SciLifeLab in brief

Over the past three years, Science for Life Laboratory (SciLifeLab) has been built up in Stockholm and Uppsala to serve as a national infrastructure for high-throughput and technically advanced research in the life sciences, and to provide an attractive research environment for top-level research groups. SciLifeLab was established in 2010, with support from the Swedish government. It is a collaboration between the Royal Institute of Technology (KTH), Karolinska Institutet (KI), Stockholm University (SU) and Uppsala University (UU).

SciLifeLab’s vision is to be an internationally leading center in large-scale life science research. With the motto Health and Environment the research supported and performed is spanning a broad field, aiming not only for deeper knowledge about human diseases, improved health care, development of diagnostic tools and potential drugs, but also for mapping of microbial activities in sensitive ecosystems, engineering for biofuel production and plant biotechnology.

By combining a “tool box” of advanced instrumentation and expertise from a wide range of life science areas, interdisciplinary research involving highthroughput DNA sequencing, analysis of gene expression, protein profiling, cellular profiling, advanced bioinformatics, biostatistics and systems biology, is carried out. The two nodes in Stockholm and Uppsala will in the middle of 2013 merge into one organization. This report describes the activities of SciLifeLab Stockholm during 2012.

SciLifeLab Stockholm 2012

The year of 2012 has been an exciting and rewarding year for SciLifeLab Stockholm.

The development of SciLifeLab Stockholm has continued at a rapid pace during 2012 and the year has been scientifically productive. The center has noticed an increased interest from researchers to use the state-of-the-art technologies provided by the platform facilities. Hundreds of collaborative and service projects have been completed with users from all major universities in Sweden. To further broaden the resources available, three new platform facilities have been established. The center has also expanded with an additional 170 researchers, reaching 350 persons at the end of 2012. These include almost 40 senior research leaders performing research in a wide range of molecular bioscience areas. SciLifeLab Stockholm will continue to expand during 2013 when an adjacent building will be inaugurated, then encompassing more than 600 researchers and 14,000m2 of space for the technical infrastructure and research within large-scale life science. Substantial external funding has enabled investments in new instrumentation and recruitment of personnel to several platform facilities. Through generous grants from the Knut and Alice Wallenberg Foundation the Genomics facility has been able to triple the sequence capacity during the year and an infrastructure for in-depth bioinformatics support has been established. This kind of support is an important key for success in on-going large-scale studies.

The strengthened research environment is illustrated by the considerable increase in number of publications produced by SciLifeLab Stockholm researchers over the year. During 2012 one article per week has been published in high impact journals such as Nature, Science and PNAS. Read more about some of the research highlights at SciLifeLab Stockholm on page 12 to 22. Several patents have also been filed, and there are lively collaborations with industry on different levels.

Development of SciLifeLab Stockholm from the start in 2010. The center has expanded with new Platform Facilities and research groups each year. In 2013 the nodes in Stockholm and Uppsala will merge into one organization and become a national infrastructure for large-scale biosciences.

In 2012, the Swedish government decided on additional funding to SciLifeLab, with the mission to unify the Stockholm and Uppsala nodes and become an infrastructure with a national responsibility. SciLifeLab will provide large-scale state-of-the-art instrumentation and technical know-how, including in-depth bioinformatics support, to all Swedish researchers in order to strengthen multidisciplinary research throughout the nation.

SciLifeLab in constant progress

SciLifeLab aims to be an internationally leading center for providing and developing state-of-the-art technology and expertise in large-scale molecular biosciences and to produce first-class interdisciplinary research.

From 2013 SciLifeLab will receive substantially increased funding from the Swedish government and become a national infrastructure for large-scale bioscience. A new organization will start in the middle of 2013 when the two nodes in Stockholm and Uppsala will merge into one organization with a common board.

The aim is also to accommodate national and international research groups with strategically important expertise to join SciLifeLab. Fellowships will allow young research leaders to work in the interdisciplinary environment of SciLifeLab for a shorter or longer period and contribute to an even more dynamic research environment.

SciLifeLab’s vision to take part in strengthening health care, through new technologies and products, has resulted in the start up of two new areas in the center. The first one is a platform for Drug Development that will bring activities already ongoing, such as small molecule library and RNAi cell screening, under one roof and expand and complement these activities with expertise in drug development. Second, to further strengthen the collaboration and integration with the health care sector, SciLifeLab Stockholm will expand its activities with a clinical genomics facility to perform next generation sequencing on patient samples with fast processing time.

The links to other Swedish universities will be further strengthened during the years to come, as SciLifeLab will have a national responsibility to provide access to advanced technologies and expertise in bioscience. Several areas of expertise in life science at other universities will also be formally linked to SciLifeLab. The National Reference Committee, with representatives from all major Swedish universities, will continue to give strategic advice on the development of SciLifeLab and monitor the accessibility and output from the platform facilities. In order to provide access to technologies and expertise and to support knowledge exchange and the spread of new technologies, space for guests has been made available both in offices and laboratories and a program of courses, workshops and seminars will be provided.

During 2013 SciLifeLab Stockholm will grow with approximately 30 new research groups, encompassing more than 600 persons at the end of the year.

The organization of SciLifeLab Stockholm 2012

SciLifeLab Stockholm is a collaboration between the Royal Institute of Technology (KTH), Karolinska Institutet (KI) and Stockholm University (SU). The SciLifeLab Board has the responsibility for decisions regarding the budget and strategic development of the center. The board consists of six members, two from each university. An international Scientific Advisory Board and the National Reference Committee give advice to the board. In the end of 2012, a new operative management structure at SciLifeLab Stockholm was introduced comprising three Center Directors and three Scientific Directors, each representing one of the universities. The Center Directors are responsible for implementing the board’s decisions about the center budget and activities. Moreover, a Site Director is responsible for the day-to-day operations.

is generally used. The platform facilities are units each representing a certain technology and which can offer services to internal and external research groups. A number of senior researchers are appointed as Platform Directors with responsibility for the scientific development of the platforms. The day-to-day activities of the platform facilities are headed by Facility Managers. The Affiliated Faculty of SciLifeLab Stockholm is a network of representatives from all departments, research centers and other organizations in the Stockholm region with an interest in the activities at SciLifeLab Stockholm. In order to coordinate activities between the Stockholm and Uppsala node and plan for a common organization in 2013 a coordination committee was initiated in 2012. This committee consists of one representative from each of the four universities (KTH, SU, KI and UU). The research leaders of SciLifeLab Stockholm are presented on page 24–25. More information about the Platform facilities and the services available can be found on page 10 and 28–45 and at

The center included seven platforms during 2012 and a number of platform facilities. The platforms represent areas of research where a combination of technologies

SciLifeLab Stockholm Annual report 2012 | 9

The platforms offer technology infrastructure and competence

Each platform facility is headed by a facility manager with responsibility for the daily work, personnel and budget. The strategic development and overall budget for the platform is managed by a platform director. In several cases, the platform facilities in Stockholm are jointly run with a similar facility at the Uppsala node. This allows efficient handling of large numbers of projects and samples. In other areas, the technologies and expertise are unique to each site. During 2012, the number of projects carried out in the facilities has increased considerably with users from all Swedish universities. The projects cover a broad range of molecular bioscience research and considerable parts of the research being performed is focusing on an increased molecular level/mechanistic understanding of human diseases, plants, and microbes, finding new biomarkers for disease and development of new treatments. 10 | 2012 Annual report SciLifeLab Stockholm

The Genomics platform is the most established platform and carried out several hundreds of research projects during 2012. It offers massively parallel DNA sequencing and bioinformatics support for projects in plants, humans, microorganisms and cell lines. With the latest instrumentation, an entire human genome can be sequenced in 27 hours. During 2013, the new technology and expertise will enable a new facility “Clinical genomics� to emerge. Next generation sequencing on patient samples will be performed in collaboration with the treating physicians and hospital geneticists. The MS proteomics platform as well as the Functional biology and Bioimaging platforms are also carrying out large numbers of projects. Other platforms, such as Affinity proteomics and Functional genomics require more detailed experimental planning and are customized for each user. In many cases, SciLifeLab Stockholm can provide unique competence and resources. One example is the Affinity Proteomics platform that uses the unique resource of affinity reagents from the Human Protein Atlas (HPA) project allowing high-throughput biomarker discovery screening in large cohorts of clinical samples. This platform also provides means to validate antibodies and/or cell lines in a subcellular fashion using the HPA reagents and confocal microscopy. The Platform facilities are presented in more detail on page 28 to 45. More information about the Platform facilities is available at

The Subcellular Protein Atlas

All cells of higher organisms such as humans or animals are organized into compartments with specialized functions. These so called organelles are defined by their own chemical characteristics and molecular composition. For example an organelle called mitochondrion has the function to provide energy for the cell, whereas the cytoskeleton serves to maintain cellular shape, movement and functions as a railroad for intracellular transport. Thus, knowing the exact

selected based on gene transcript expression levels (1). Furthermore, a pipeline for validation of antibody binding and protein subcellular location using siRNA (2) and automated classification of staining patterns (3) has been developed. Beyond this, we have demonstrated the added value of using a complementary technique such as live cell imaging of tagged proteins to allow a complete investigation of the subcellular human proteome (4).

subcellular location of a given protein is of great importance as it indicates the protein function and leads to a better understanding of how and why proteins interact in networks and signaling pathways.

Ever since the human genome was first characterized much efforts has been put into the identification and characterization of the gene products – the proteins. A key to unlock a more complete understanding of the information embedded in the human genome and the complex machinery of living cells is to know the subcellular localization for every protein. As part of the Human Protein Atlas project our research is therefore focused on determining the subcellular localization of all human proteins by the use of specific antibodies and high-resolution microscopy. During 2012, the Subcellular Protein Atlas program at SciLifeLab Stockholm has expanded in different directions, as reported in several publications. The panel of human cells has increased to fifteen cell lines of different origin from which the most suitable is

Currently, the Subcellular Protein Atlas contains ~100,000 images corresponding to the localization of over 12,000 proteins. The aim of the presented atlas is to make subcellular information for all human proteins publicly available, with the ultimate aim to facilitate functional studies of proteins. References 1.

Targeting DNA repair to find novel anti-cancer treatments

Cancers are characterized by genetic mutations and an overall high load of DNA damage, which can be exploited for novel therapies. Our laboratory focuses on a multidisciplinary approach to understand basic properties of DNA repair at a molecular level, and identify and validate novel protein targets within the DNA repair pathway (1, 2). Using an open innovation approach, in close collaboration with academic groups and clinicians, we develop small molecule inhibitors to novel targets that are tested in early proof of concept trials in patients.

Cancer remains the most common cause of death for individuals aged below 80 in industrialized countries and novel more effective treatments for cancer are urgently needed. Traditional radio- and chemo­ therapy work by causing an unbearable load of DNA damage in cancer cells, which effectively eradicate the cancer, but also cause harmful side effects. Our aim is to selectively introduce DNA damage in tumors without harming non-malignant cells. We previously demonstrated that cancers caused by mutations in BRCA1 or BRCA2 genes rely on PARP for survival and that PARP inhibitors can selectively kill off the cancers (3). This is now tested in numerous clinical trials. Based on this new concept of synthetic lethality, we are identifying genes that are required for survival only in the mutated cancer cells.

required for cancer development. However, to avoid lethal DNA damage cancer cells appear dependent on new proteins to survive; such as nucleotide hydrolases. By specifically targeting nucleotide hydrolases we have identified a new strategy to attack cancer. We have developed small molecule inhibitors against these proteins, which kill cancer cells without harming normal growing cells. Our most effective inhibitors will be further optimized, tested in in vivo tumor models and passed on to clinical trials with the aim of treating cancer patients. By working in a multidisciplinary fashion we are able to combine expertise from several disciplines such as biochemistry, medicinal chemistry, molecular biology, clinical oncology and pharmacology. In addition, we are fortunate to have a number of collaborations, both national and international, across a range of disciplines to complement our in-house expertise. References 1.

Membrane protein biogenesis

All cells are surrounded by a lipid membrane that separates them from the outside world and protect their content. Cell membranes are stuffed full of proteins. Membrane proteins are central players in all types of cells, from bacteria to man. They make it possible for cells to take up nutrients from the environment, to excrete waste products, and to receive and transmit various kinds of signals from other cells. Being

enter a membrane (1). This has been a conundrum, but we now understand the basic principles. Another advance is the development of a new method that allows us to measure forces acting on membrane proteins during their insertion into the membrane (2). This has not been possible before, and opens up a new window for probing the molecular mechanisms that underlie membrane protein folding in the cell.

the gatekeepers of the cell, membrane proteins are also favorite drug targets; it is estimated that more than half of all drugs currently on the market bind to and change the activity of membrane proteins.

Much effort is currently spent across the world to determine high-resolution structures of membrane proteins in order to understand their function on the molecular level. But in order to fully understand membrane proteins, structures are not enough. We also need to figure out how membrane proteins are manufactured in the cell, how they are inserted into the membrane, and how they fold into the final structure. This is important not only from a basic science perspective, but also to understand how mutations in medically important membrane proteins can cause proteins to misfold and thereby destroy their function. Our research is focused on these early stages in the life of membrane proteins. In particular, we have recently been able to discover some “tricks” that nature has invented in order to make membrane proteins with membrane-embedded parts that by themselves cannot

Reading the Genome

After the human genome was sequenced in 2000, it was hoped that the knowledge of the entire sequence of human DNA could rapidly be translated to medical benefits such as novel drugs, and predictive tools that would identify individuals at risk of disease. However, this turned out to be harder than expected, one of the reasons being that only the 1% of the genome that codes for proteins could be read. The remaining 99% contains information about when and where these proteins are made, and is to us like a book written in a foreign language – we know the letters but cannot understand why a human genome makes a human or the mouse genome a mouse. Why some individuals have higher risk to develop common diseases such as heart disease or cancer is even less well understood. The Taipale group addresses this problem by studying the human proteins that read the gene regulatory code: transcription factors (TFs).

The human genome encodes approximately 1000 TFs, and they bind specifically to short 5 to 20 base pair sequences of DNA, and control production of other proteins. Through the use of a highly automated laboratory, we have identified DNA sequences that bind to over 400 such proteins, representing approximately half of all human TFs. We have also developed computational tools that can use such information to identify gene variants that are linked to disease. We have analysed one particular single nucleotide variant in a region associated with increased risk for developing colorectal and prostate cancers. Although 16 | 2012 Annual report SciLifeLab Stockholm

this variant increases cancer risk only by 20 per cent, it is very common and therefore accounts for more inherited cancer than any other currently known genetic variant or mutation. We removed the gene region containing the risk variant from the mouse genome and found that as a result the mice were healthy, but displayed a small decrease in the expression of a nearby cancer gene, called MYC. However, when these mice were tested for the ability to form tumors after activation of an oncogenic signal that causes colorectal cancer in humans, they showed dramatic resistance to tumor formation. The removed gene region thus appears to act as an important gene switch promoting cancer, and without it tumors develop much more rarely. This study highlights that growth of normal cells and cancer cells is driven by different gene switches, suggesting that further work to find ways to control the activity of such diseasespecific switches could lead to novel, highly specific approaches for therapeutic intervention.

Recent studies have shown that the sodium pump, Na,K-ATPase, not only pumps ions but also has an important role as a signal transducer (1). We have shown that binding of cardiotonic steroids to Na,KATPase trigger frequency modulated Ca2+ oscillations with downstream anti-apoptotic effects.

The functional significance of neuronal expression of two different isoforms of Na,K-ATPase, a1 and a3, has been studied by intracellular Na+ imaging. The a3 isoform, which has a higher Na+ affinity than a1, was identified to have a specific role in restoration of intracellular Na+ after the transient influx that occurs during synaptic activity (2). Applying super resolution microscopy (STED, PALM, SIM) we revealed for the first time the discrete localization of the neuron specific a3 isoform to the neck of dendritic spines (3) and also the spatial interrelationship to dopamine D1R receptors (4).

Spatial transcriptomics of the brain

The human body comprises over 100 trillion cells and is organized into more than 200 different organs and tissues. The development and organization of complex organs, such as the brain, are far from understood and there is a need to dissect the expression of genes using quantitative methods. The organs are in themselves a mixture of differentiated cells to enable all body functions such as nutrient transport, defense etc. Consequently, cell function is context dependent, and the context provided by tissue structure is being disentangled at the transcriptional level within the spatial transcriptomics project.

The new advances in high-throughput genomics have reshaped the biological research landscape and in addition to complete characterization of genomes we are also able to study the full transcriptome in a digital and quantitative fashion. The bioinformatics tools to visualize and integrate these comprehensive sets of data have also been significantly improved during recent years. Findings by deep RNA sequencing have demonstrated that a majority of the human genes are active in a cell and that a large fraction (75%) of the human protein-coding genes are expressed in most tissues. The transcriptional machinery can therefore be described to be promiscuous at a global level but remains dynamically complex, demonstrated by burst transcription, where brief pulses of transcription are separated by periods of transcriptional silence. 18 | 2012 Annual report SciLifeLab Stockholm

We have recently devised a simple strategy that enables global gene expression analysis in histological tissue sections, yielding transcriptomic information with two-dimensional spatial resolution. This enables the identification of individual transcriptomes of single cells while maintaining the positional information of those cells in the tissue. The RNA sequencing data is visualized in the computer together with the tissue section, for instance to display the expression pattern of a gene of interest across the tissue. It is also easy to mark different areas of the tissue section on the computer screen and obtain information on differentially expressed genes between any selected areas of interest. We are currently creating spatial transcriptional maps of the brain, arguably the most complex organ in the body, with at least hundreds of different distinct neuronal subtypes that are interconnected in precise patterns. Our aim is to improve understanding of neurological and psychiatric diseases, as our current knowledge is still limited, contributing to the difficulty in developing therapies for many of these diseases. Psychiatric and neurological diseases cause much suffering of affected patients and their families and enormous costs to society. References Patent PCT/EP2012/056823

Data analysis. The data from the spatial transcriptomics experiment is visualized in the spatial transcriptomics viewer software. Virtual analysis of the tissue section is enabled and the user can select and analyze the gene expression in a cell or an area of interest. The user can also look at differential expression between selected regions, or perform an automated virtual analysis for identification of cell types based on predefined expression profiles.

Understanding the molecular basis of nerve signals Tracking the activation cycle of a voltage-gated ion channel

Ion channels that open and close in response to electrical signals are membrane proteins that constitute the fundamental building blocks responsible for e.g. our nerve signaling and heartbeats. These channels sense differences in voltage across a cellular membrane with four special voltage sensor parts (domains) whose structure changes. It has previously not been possible to determine how these changes occur. During the last year, we were able to solve this problem with a new combination of experiments, bioinformatics and simulations, which now enables us to track a complete cycle of a voltage sensor activation in response to voltage in full atomic detail.

Since it is difficult or impossible to determine a crystal structure with a voltage applied, the only structures available this far have corresponded to the open state of the Kv1.2-2.1 potassium channel. However, in collaboration with Linköping University we have been able to design electrophysiology experiments that capture information from intermediate states only visited briefly during channel opening or closing. This provides a wealth of new indirect structural information, and in combination with molecular modeling and molecular simulation it enabled us to predict a range of five different atomicdetail models corresponding to states ranging from fully activated to resting voltage-sensor domains (1). This results in a virtual movie of the complete cycle of structural changes of the ion channel, and makes it possible to explain how the gating occurs. For each 20 | 2012 Annual report SciLifeLab Stockholm

intermediate stage, one more charge in a specific part of the protein is moved across a hydrophobic region in the core of the ion channel, which effectively moves it from one side of the membrane to the other (2). We have also been able to use combined experiments and simulations to show that a specific residue (F233) in this region is responsible for making the closing process of potassium channels very slow (3). This likely explains a key property of our nerve system, where all nerve impulses are created by fast (sodium) channels first opening to depolarize the membrane, followed by the slower potassium channel opening to restore the equilibrium – if the latter closed instantly the nerve system would not work.

Bioinformatics for network and systems biology

As more and more high-throughput biological data is generated, there is a growing need to understand how genes and proteins are organized in networks. We have developed a bioinformatics framework for mapping diverse types of data into a single network of functional couplings. Such network maps are a tremendous

a 5-fold increase in sensitivity compared to traditional gene enrichment analysis, which does not use a network (2). Moreover, we have developed an efficient and highly accurate bioinformatics method that improves gene list analysis by clustering the genes into distinct functional groups (3).

resource for identifying the functional partners of genes and proteins, and to analyze relations between groups of genes. To this end, we have developed bioinformatics tools to assess the statistical significance of network crosstalk between gene groups. We are also elucidating gene regulatory networks by perturbation experiments and improved bioinformatics methodology.

Network biolog y. FunCoup is a data integration project for producing global comprehensive gene/protein networks of functional couplings. Release 2.0 was built using 9 different types of high-throughput data from 11 different species (1). FunCoup achieves its high coverage by orthology-based transfer of functional coupling between species. The FunCoup website provides unique facilities for analyzing network context of query genes and the conservation of subnetworks in multiple species. Functional analysis. The FunCoup networks can be used for pathway annotation of gene lists using ”Network Crosstalk Enrichment Analysis”. This measures enrichment of network crosstalk between an experimentally derived gene list and known pathways. We have shown that this approach yields 22 | 2012 Annual report SciLifeLab Stockholm

Systems biolog y. Dynamic transcriptional gene regulatory networks can be inferred by perturbing some genes, e.g. with RNA interference, and measuring the effect this has on other genes. Several modeling techniques exist for such inferences, but a major problem has been estimating the sparsity of the network, leading to very poor accuracy. To resolve this, we have developed a method that, given sufficiently informative data, predicts the optimal sparsity and produces correct regulatory networks (4). Together with SciLifeLab facilities, we are elucidating gene regulatory networks relevant to cancer. References 1.

Collaboration with industry

Collaborations between academia and industry are becoming increasingly important and SciLifeLab Stockholm is working actively to find new forms of collaboration with national and international industry partners. These collaborations have large potential for societal gains in a wide range of applications. Examples range from a faster route to convert new knowledge into products or therapies in medicine and health care to new ways to produce biofuels.

Based on the advanced technologies and instrumentation available, SciLifeLab Stockholm aims to be involved in the development of new techniques and instrumentation in collaboration with industry and to be a reliable and competent partner for development and testing of new technology. Several such collaborations are ongoing at SciLifeLab Stockholm. Another interesting possibility for industrial collaboration is to get smaller companies to use the resources at SciLifeLab as means for increasing their international competitiveness. This will be based on a full-cost policy, but might still be attractive for some companies. Finally, SciLifeLab Stockholm is an attractive partner for pharmaceutical industry in larger scientific studies. One interesting possibility here is to use the infrastructure built up in SciLifeLab along with Sweden’s unique clinical materials and skills to promote Sweden as a location for research on the major international pharmaceutical companies.

research program has also been established for collaborations between AstraZeneca and SciLifeLab associated groups. Example of collaboration: GE Healthcare

The GE Healthcare DemoLab is a facility equipped with GE Healthcare’s instrumentation and reagents for life science research. This complements the instrumentation and competence provided by SciLifeLab and facilitates collaboration between industry and academia. The instrumentation includes ÄKTA for purification and analysis of biomolecules, Biacore and MicroCal technology for biomolecular interaction analysis and the imaging systems Image Quant and Typhoon, and IN Cell Analyzer. During 2012, GE DemoLab has been carrying out a large number of projects together with research groups in the Stockholm-Uppsala region.

In June 2012, AstraZeneca started up the Translational Science Centre in collaboration with Karolinska Institutet. The center is situated at SciLifeLab Stockholm and will be focusing on finding biomarkers for different chronic diseases, such as cancer, rheumatoid arthritis, cardiovascular disease and dementia.
