Message from the Chair Reflecting on the recent activity of the Biomedical Sciences Department, I have the sense that efforts begun in the last few years are coming to fruition and the deDr. Rena D'Souza partment is now moving "full steam ahead" toward becoming one of the top biomedical sciences departments in the country. This newsletter reports on some of the activities and happenings in our department in 2008. Progress was made, challenges were addressed, and new initiatives were begun in our teaching, research and service responsibilities. Significant advances were made in the training and education of students. Our newly funded NIH Comprehensive T32 grant, B-STARS, offers research training and development for dual-degree (DDS/PhD) students, PhD-only students, postdoctoral fellows and MS clinical researchers. Another NIH-funded initiative involving several BMS faculty is the R25 Oral Health Research Education project ("CUSPID: Clinicians Using Science Produce Inspired Dentists"). The goal of CUSPID is to create a four-year curriculum for the predoctoral students on the use of evidence-based dentistry (EBD). In this initial year of the funding period, the first-year students were introduced to the concept of evidence-based dentistry and its importance. In the 2009-2010 academic year, the second year of instruction will be initiated, and by 2011-2012, all four years of EBD courses will have been introduced. Another "first" was the use of peer-teaching of dissection in the first-year Gross Anato-
my course. Groups of six students, divided into subgroups of three, took turns teaching each other the dissections they performed throughout the semester. The instructors reported greater student interest and engagement in the course work. Our research programs continued to be productive in 2008. The programs in developmental biology and genetics of craniofacial tissues, morphogenesis and stem cellmediated tissue engineering and regenerative medicine, TMJ development and response to pain, mineralized tissues studies, and the development of biomedical dental devices were strong and contributed to the knowledge base in each of these areas. Several new and renewed NIH R01 applications were funded along with grants from other agencies. The time of publication of this newsletter coincides with the passage of the American Recovery and Reinvestment Act and the award of incentive monies to the NIH. I am pleased that the department is well positioned to benefit from the unprecedented opportunity to seek funding for projects and equipment that will produce significant results within a two-year time period. We appointed additional adjunct faculty to our department and continue to do so in an effort to develop professional affiliations with the top researchers and clinicians in many of the fields of study listed above. These and other experts in the biomedical sciences were featured speakers in our Pathways to Excellence seminars, which is reaching the end of another successful series of presentations on cuttingedge research. The faculty in the Department of Biomed-
ical Sciences contributed significantly to professional service at all levels in 2008 and held important offices in the American Association of Anatomists, the American Association for the Advancement of Science, the International Association for Dental Research and other organizations. Specific leadership and activities by our faculty are listed on pages 14 and 15. The department is best known by the achievements each of its faculty, staff and students contribute every day. The wonderful mix of personalities, nationalities, and abilities makes our department a vibrant place to work; the collective energy and collegiality of the faculty and staff of this department are a daily inspiration to me. Of tremendous importance is the continued support of our programs and activities by Dr. James Cole, Dean. We thank him profusely, as well as Drs. Larry Bellinger and Charles Berry, who have given much administrative assistance and encouragement. Our cumulative efforts are directed toward the basic goals of helping Baylor College of Dentistry educate excellent dentists and produce top-notch research that will eventually lead to a better understanding of the etiology of craniofacial, oral and dental diseases. The following pages of this newsletter showcase these efforts taking place during 2008. We look forward to the activities and challenges ahead of us in 2009, which we will report in electronic format in the next annual newsletter. In the meantime, we send best wishes to you, our colleagues and friends around the world, and invite you to share your comments with us about our newsletter and to stop by to visit Baylor College of Dentistry when you are in the Dallas area.

Dr. Yongbo (Bob) Lu
Yongbo (Bob) Lu, M.D., Ph.D., is the most recent faculty member to join the Department of Biomedical Sciences. He was educated at Qingdao Medical College, Shandong, China, where he earned M.D. and M.S. degrees. He was an Instructor in the Department of Medical Microbiology at the Qingdao Medical College from 1997 to 1999.
In 1999, Dr. Lu began a postdoctoral fellowship lasting until 2002 at the University of Missouri-Kansas City (UMKC) in the Department of Oral Biology. He earned a PhD in that department in 2007 and then was supported by another Postdoctoral Fellowship from 2007 to 2008. His appointment as Assistant Professor at Baylor College of Dentistry became effective on January 1, 2009.
Gabriele Mues, M.D., Assistant Professor, has a wealth of research experience in molecular biology and genetics acquired in several settings. She was born and educated in Germany where she earned an M.D. degree attending the Universities of Marburg and Essen and later, a doctoral degree in academic medicine followed Dr. Gabriele Mues by a master’s degree in psychology at the University of Bochum. She passed the U.S. Medical Licensing Examinations (USMLE) 1 and 2 in 1997, and the USMLE 3 in 2003. In 2004 she was board-certified in clinical pathology by the American Board of Pathology. After interning in hospitals in Karlsruhe and in Bochum, Germany, Dr. Mues came to the United States in 1981 to work as a Research Fellow in neuropeptide research for two years at the School of Public Health at the University of California, Berkeley. From there, she moved to the north Texas area where she held several positions at the University of Texas Southwestern Medical Center and at Baylor University Medical Center. Dr. Mues joined the Texas A&M Health Science Center
Dr. Lu's research is mainly focused on odontogenesis, specifically on studies of the way in which cranial neural crest cells migrate to the frontonasal processes and first branchial arches, and how they interact reciprocally with the dental epithelium and differentiate into odontoblasts forming dentin. He is particularly interested in the roles of Wnt/β-catenin signaling, FGF signaling as well as transcription factors, Runx2 and Twist1, in odontogenesis, using a transgenic mouse model, in vitro tooth germ culture, and time-lapse imaging approaches. He believes these studies will produce further insights into the molecular mechanisms of tooth morphogenesis, and will also provide molecular clues for the screening and treatment of human genetic disease. Dr. Lu was the recipient of the Webster Jee Young Investigator Award in 2005 from the American Society for Bone and Mineral Research (ASBMR)-International Chinese Hard Tissue Society (ICHTS). He also won the Young Investigator Award in 2006 at the ASBMR 28th Annual Meeting and the New Investigator Award at the 9th International Conference on the Chemistry and Biology of Mineralized Tissues in 2007. Dr. Lu is a co-author of 20 articles published in peer-reviewed journals; nine of these articles are first-authored or cofirst authored.
Baylor College of Dentistry in 2006 as a Research Associate I in the Department of Biomedical Sciences. She was appointed Assistant Professor in 2008. In her career, Dr. Mues has been involved in both clinical and basic research. The former encompassed studies about the diagnostic value of enzyme excretion patterns, which were conducted as part of her doctoral thesis. Later Dr. Mues concentrated on the development of clinical molecular tests such as assessment of clonality and “loss-of-heterozygosity (LOH)" in tumor cells and the evaluation of bone marrow engraftment and gene mutations in a variety of disorders. Previous basic science research included early investigations on the physiological and behavioral effects of neuropeptides followed by a shift of interest towards molecular biology and genetics with isolation and structural evaluation of several genes, including heat shock, neurotransmitter- synthesizing and radiation-induced genes. Dr. Mues' current research interests lie in the area of molecular tooth development and the genetics of tooth agenesis. Several genes which are expressed in early tooth development have been shown to carry mutations in patients with inborn missing teeth. However, for the majority of tooth agenesis patients the causative genes have not yet been identified. Identification of these genes and their functional analysis is important for genetic counseling, early diagnosis, development of optimal therapy including gene product replacement, tooth bioengineering and regeneration, and for gaining basic knowledge about tooth development in general.
BMS Faculty Team-Teach New D1 Course in Evidence-Based Dentistry (EBD) In April 2008, BCD received funding from the National Institute for Dental and Craniofacial Research (NIDCR) for an Oral Health Research Education (R25) grant application that proposed to implement a series of curricular changes collectively designated as "CUSPID" (Clinicians Using Science Produce Inspired Dentists). CUSPID outlined multi-pronged strategies for the early instruction of clinicians-in-training with the key skills required for the filtering, appraisal and synthesis of scientific information needed for clinical decisions. Specifically, CUSPID seeks to create a curricular theme throughout all four years of dental school centered on the knowledge, principles, and skills of scientific inquiry necessary for the dentist to critically evaluate new information and advances in treatment for evidencebased practice and to participate in dental practice research networks. BMS faculty, led by Dr. Paul Dechow, have been instrumental in the development of a course for first-year dental students entitled Introduction to EvidenceBased Dentistry & Clinical Research. The year-long course, which consists of large group interactive sessions and small group dis-
Dr. Paul Dechow
cussions and seminars, has two primary aims: 1) to provide a foundation of knowledge important for the effective practice of EBD; and 2) to begin to develop the practical skills needed for such practice. Foundational knowledge includes a background in applied clinical epidemiology, biostatistics, and some areas of modern dental and craniofacial research. The development of practical skills will emphasize how to evaluate clinical studies, how to formulate a focused clinical research question, and how to search the dental literature to find and evaluate evidence to answer that question. The didactic portion of the course makes generous use of audience response systems (‘clickers’) to involve students interactively in course content. The small group sessions consist of biweekly meetings of around eight students with one or two faculty to discuss an assigned paper on a clinically-relevant topic using a standardized article review format. Paper topics in the Spring semester include breastfeeding and caries, fluoride in water and hip fracture, tobacco use and tooth loss, and fluoride varnish and caries prevention. Dr. Dechow shares the course directorship with Dr. Hoda Abdellatif (Department of Public Health Sciences). Drs. Bob Hinton, Bob Hutchins, Lynne Opperman, Emet Schneiderman, and Robert Spears have assisted in the small group sessions. This course provides the foundation for additional didatic and practical experiences that will be developed in the second, third, and fourth years of the curriculum.
Dr. Williams Presented with BMS Golden Apple Educator Award Dr. Fred Williams, Associate Professor in Biomedical Sciences, was presented with the first Biomedical Sciences Golden Apple Educator Award at the D1 luncheon on August 12, 2008. The award was established by Dr. Rena D'Souza, Professor and Chair of Biomedical Sciences, to honor faculty members for excellence in basic science teaching in the biomedical sciences. Dr. Williams received a golden brass apple trophy with his name inscribed on it and $1000 to be used to travel to a professional conference on educational technology. A plaque with Dr. Williams' name on it was hung in the Blanton Conference Room and Library on the 4th floor; future award winners' names will also be inscribed on it. Dr. Williams started teaching physiology at BCD in 1972, and since then has spent hours and hours both teaching in class and meeting with students one-on-one outside of class. Just one indication of Dr. Williams' influence on students' learning is that in 27 of the last 30 years, physiology has had the highest score made by BCD students on the Part I National Board scores.
Dr. D'Souza stated, "Dr. Williams is a very special member of the Biomedical Sciences department, and we are honoring him for his many years of excellent teaching. He serves as an outstanding example to other faculty of dedication to his profession and to his students." In accepting the award, Dr. Williams said, "I am deeply honored to be chosen to receive the first Golden Apple Award, and I accept it on behalf of all my colleagues in Biomedical Sciences, who have worked very hard over the years to give the students at BCD a strong foundation in the biological sciences." Dr. Williams (middle) is pictured with Dr. D'Souza during the award presentation, along with a fellow Physiology teaching colleague, Dr. Larry Bellinger, Regent’s Professor in Biomedical Sciences and Associate Dean for Research and Graduate Studies.

Dr. Feng Invited to University of Western Australia
Dr. Opperman Attends Program at Harvard
Dr. Jian (Jerry) Feng, Professor, was invited to visit the University of Western Australia (UWA), Perth, as a Raine Visiting Professor for three weeks in March 2008. The professorship was sponsored by the Raine Medical Research Foundation and the Centre for Orthopaedic Research, School of Surgery and Pathology. Dr. Feng was one of a total of 14 visiting professors from the U.S., England, CanDr. Jerry Feng ada, and South Africa who spent a few weeks working with faculty researchers at UWA during 2008. During his visit, Dr. Feng lectured to the students, guided the graduate students and postdoctoral fellows in their research, and interacted with faculty members on several collaborative projects. Specifically, Dr. Feng gave three talks: a Raine Visiting Professor Lecture to faculty, students and staff in the School of Surgery and School of Medicine (entitled "Think Outside the Current Dogma While Doing Daily Research"), a lecture on Osteocyte Research, and a lecture on cell fate. Most importantly, Dr. Feng and Professor Ming Hao Zheng, Director of Orthopaedic Research at UWA, worked on a joint project that was recently funded by the National Health and Medical Research Council (NIH equivalent). Dr. Feng also spent a day at the ANZAC Research Institute, University of Sydney, Australia, where he gave a talk entitled “DMP1 Roles”.
Dr. Lynne Opperman, Professor, was selected through an application process to attend the Management Development Program at Harvard University held on June 14-28, 2008. This course is offered through the Programs in Professional Education of the Harvard Graduate School of Education. The goal of the program is to prepare participants to become better leaders in their institutions and Dr. Lynne Opperman to teach them to lead in ways that support institutional objectives. The topics covered included Fostering Innovation and Change, Diversity and Community, and Professional Renewal. In her role as Director of Technology Development, Dr. Opperman benefited from the interaction with both the Harvard faculty and the participants, who come from a broad spectrum of higher education institutions and job responsibilities. Dr. Rena D'Souza, Professor and Chair of Biomedical Sciences, believes Dr. Opperman was ideal for this program, based on her willingness and desire to take on leadership roles in the department, in BCD and the HSC. She commented, "I know Lynne contributed valuable insights in group discussions and was enriched with the new knowledge she gained through this experience. Importantly, she became a program alumnus who brought much distinction to the program."
Faculty and Staff Promotions The following members of BMS were promoted in 2008: Dr. Lynne Opperman, promoted to Professor Dr. Allen Honeyman, promoted to Associate Professor with tenure Dr. Robert Spears, promoted to Associate Professor with tenure Ms. Connie Tillberg, promoted to Research Associate Ms. Vanessa Winger, promoted to Research Associate
Congratulations to all!
BMS 2009 Faculty Retreat Dr. Charles Shuler, Dean of The Faculty of Dentistry, University of British Columbia (UBC), will be the keynote speaker at the Biomedical Sciences’ annual retreat on April 24, 2009. The department has invited Shuler to share his experience in integrating the basic and clinical sciences, as well as leading initiatives in translational research. Prior to his appointment as Dean at UBC, Dr. Shuler held the George & Mary Lou Boone Chair and Professorship of the Center for Craniofacial Molecular Biology, School of Dentistry, University of Southern California, from 1995 to 2007. Dr. Shuler is now a leader in dental education, but still an active scientist, attested by his role as principal investigator in a major grant from NIDCR on the molecular mechanisms of TGF- β3 signaling in the regulation of palatal fusion. Dr. Shuler also played a major role in the development of a problem-based learning curriculum at USC and will be sharing his experience with the retreat attendees. The BMS faculty are looking forward to spending a stimulating day interacting with this distinguished colleague.

BMS Interest Groups Offer In-Depth Study of Topic Areas Mineralized Tissue Interest Group The Mineralized Tissue Interest Group (MTIG) was initiated in the fall of 2007. MTIG consists of 8-9 faculty members, along with approximately 15-20 postdoctoral fellows/graduates/research associates, who are involved in studies on bone, dentin and cementum. Members of the MTIG meet at noon of every other Thursday (twice a month). The major objectives of MTIG include: 1) to train junior investigators (postdoctoral research fellows/graduates/research associates) in oral presentation and discussion, 2) to obtain insights and comments on the research projects of each principal investigator, 3) to keep investigators updated about the research field of mineralized tissues, 4) to teach techniques in mineralized tissue research, 5) to enhance collaborations among research laboratories in the school as well
as in the Department of Biomedical Sciences, and 6) to broaden the knowledge of principal investigators and junior investigators. Up to February 2009, more than 20 postdoctoral research fellows/graduates/research associates had given oral presentations (sharing of their research data), and four faculty members had given seminar/journal club talks for the MTIG. The activities of MTIG have been particularly beneficial to the junior investigators who oral presentation training.
transplantation of a small region of an amphibian embryo onto a different site of a second embryo, that in a fraction of cases, developed secondary structures including a second body axis. During the 85 years hence, inductive signals and downstream pathways mediating cell fate change during development have been identified and established in different tissue contexts in model organisms and in humans. Dysregulation of the signaling pathways is often linked to cancers, other disorders and disease.

New Discoveries and Ideas in Dentinogenesis and Osteogenesis Dr. Chunlin Qin, Assistant Professor, performs research on the mechanisms governing the formation of dentin, cementum and bone, with particular emphasis on understanding the properties, Dr. Chunlin Qin tissue/cell expression, biosynthesis, metabolic pathways and biological roles of one category of non-collagenous proteins termed the “Small Integrin-Binding LIgand, N-linked Glycoprotein” (SIBLING) family. This family includes dentin matrix protein 1 (DMP1), dentin sialophosphoprotein (DSPP), bone sialoprotein (BSP) and osteopontin (OPN) and are critical for the formation of dentin, cementum and bone. Dr. Qin’s research group aims to elucidate the mechanisms of how dentin, cementum and bone are formed and mineralized under normal and pathological conditions. A better understanding of these mechanisms is essential for establishing scientifically based treatment modalities for dental and skeletal diseases such as dentinogenesis imperfecta and osteoporosis. Additionally, Dr. Qin studies the mechanisms by which FAM20C, a protein whose mutations are associated with lethal osteosclerotic bone dysplasia (Raine syndrome), is involved in dentinogenesis and osteogenesis. Following is a brief summary of the major research projects currently going on in Dr. Qin’s laboratory.
in rat bone and dentin is proteolytically processed into an NH2terminal (37 kDa) fragment and a COOH-terminal (57 kDa) fragment by selective cleavage at four NH2terminal peptide bonds of aspartyl residues, and that, in addition to its core protein form, the NH2terminal fragment also occurs as a proteoglycan in bone and dentin. Based on the hypothesis that the conversion of the full-length form of DMP1 to NH2-terminal and COOH-terminal fragments is an activation step, releasing active products at the correct time and site to control the mineralization process of
1. Roles of Dentin Matrix Protein 1 (DMP1) in Biomineralization
2. Roles of Dentin Sialophosphoprotein (DSPP) in Biomineralization
In vitro and in vivo studies have shown that that DMP1 plays a crucial role in the mineralization of dentin, cementum and bone. However, details about the precise involvement of this protein in controlling the mechanisms of biomineralization are unknown. By studying DMP1 and its fragments isolated from the extracelluar matrix (ECM) of dentin and bone, Dr. Qin discovered that DMP1
DSPP in dentin and bone is proteolytically processed into an NH2-terminal fragment (DSP) and a COOHterminal fragment (DPP). This project aims to: 1) study the functions of fulllength DSPP, of DSPP with the substitution of an amino acid residue at the cleavage site, and of DSP and DPP fragments on the mineralization of dentin and bone; 2) identify molecules that interact with these DSPP
bone and dentin and that different variants of DMP1 play different roles in biomineralization, Dr. Qin performs experiments to: 1) study the effects of the processed fragments of DMP1 on mineralization; 2) elucidate the biosynthetic pathways of DMP1 and its fragments; 3) test the in vivo effects of DMP1 variants; and 4) determine which enzyme(s) is responsible for catalyzing the proteolytic processing of DMP1. The results will help determine the mechanisms governing the mineralization of dentin, cementum and bone.
variants; 3) characterize the proteoglycan form of DSP and identify the site at which the glycosaminoglycan side chain(s) is attached; and 4) study the interactions between DSPP and DMP1 variants. Successful completion of this research will provide unique insights into dentinogenesis and osteogenesis. 3. Roles of FAM20C in the Development and Mineralization of Bone and Dentin. Mutations in the FAM20C gene are associated with lethal osteosclerotic bone dysplasia (Raine syndrome). While FAM20C is expressed at a relatively high level in osteoblasts and odontoblasts, its specific roles in osteogenesis and dentinogenesis are completely unknown. Dr. Qin’s laboratory is using transgenic and conditional gene ablation approaches to study the mechanisms by which FAM20C participates in the development and mineralization of bone and dentin. It is anticipated that these studies will help to better understand the roles of FAM20C in osteogenesis and dentinogenesis as well as elucidate the pathogenesis underlining lethal osteosclerotic bone dysplasia.
Other studies being carried out in Dr. Qin’s laboratory include: Roles of phosphorylation of SIBLING family members in biomineralization; Roles of glycosylation of SIBLING family members in biomineralization; SIBLING family members and chondrogenesis and SIBLING family members and tumor metastasis to bone.
Spotlight on Faculty: The "Evolution" of Bob Hinton Dr. Robert (Bob) Hinton followed a "long and winding road" to get to where he is today: a professor in Biomedical Sciences (BMS) who has taught many students, performed research, and given BMS a great deal of stability during periods of change. Although Dr. Hinton now teaches courses in the broad area of human anatomy (gross anatomy, head and neck anatomy, and human craniofacial development and growth), his educational background indicates that he started out in a very different field: nuclear engineering. He chose engineering because it was the era of Sputnik, when greater emphasis was being placed on the sciences in American schools; also, his father was an engineer. Dr. Hinton attended the University of Tennessee and graduated with honors with a degree in nuclear engineering. The next few years found him at the Oak Ridge National Laboratory in Oak Ridge, TN, where he worked in the computing technology division, which employed computer programs to assess safe ways of handling spent nuclear fuel. Convinced by his stint at Oak Ridge that nuclear engineering was not to be his life's work, Dr. Hinton decided to switch fields to an interest developed from electives during studies for his B.S. degree: anthropology. He decided to enter a new PhD program in anthropology being offered at the University of Tennessee by Dr. Bill Bass, a world-renowned forensic anthropologist. After completing some of the course work for an advanced degree in anthropology at the University of Tennessee, Dr. Hinton transferred to the program at the University of Michigan, where he earned his M.A. (Anthropology) and Ph.D. (Biological Anthropology). His dissertation, entitled, "The Influence of Dental Function on Form of the Human Mandibular Fossa", foreshadowed his lifelong research interest in the temporomandibular joint. This achievement was followed by a three-year NIH-funded postdoctoral fellowship at the University of Michigan Center for Human Growth and Develop-
ment and Department of Anatomy. During his postdoctoral fellowship, he met future faculty Dr. Paul Dechow (another post-doc) and Dr. Emet Schneiderman (a graduate student). His mentors for that post-doctoral fellowship were Drs. James McNamara and Dr. David Carlson, who would 10 years later come to BCD as chair of Biomedical Sciences.
given freely of his time to the department by serving on several faculty search committees, the Predoctoral Committee, and the Task Force on a new Cell/Molecular Biology course. Mostly importantly, he took on the responsibility of serving as Acting Chair of Biomedical Sciences from 2003 to 2006 and as Vice Chair from 1999 to 2003 and 2006 to 2008.
Dr. Hinton has taught in a number of courses for dental, dental hygiene and graduate students, and has served as course director of many of these. He is currently the contact PI on a Dr. Bob Hinton recently funded NIH "Research Curriculum" grant that is introducing evidence-based dentistry content throughout the four years of the DDS curriculum. He has served on many M.S. and Ph.D. committees and as a research mentor to predoctoral summer research students. His research on the development, growth, adaptation, aging and degeneration in the temporomandibular joint and other secondary cartilages has been funded by major NIH/NIDCR grants. This work produced approximately 40 peerreviewed publications and 8 book chapters.
Dr. Rena D'Souza, BMS Chair, comments that "Bob Hinton has filled many roles in this department as it has developed through the years. I know I speak for all the department personnel who are grateful for his steadfast willingness to serve as needed and for the continunity he has provided in times of change."
In addition to his teaching and research responsibilities, Dr. Hinton has been very active in institutional and professional committee work. At BCD, he has been a member of the Institutional Animal Care and Use Committee, the Strategic Planning Committee, Promotion and Tenure Committee, several SACS accreditation-related committees, the Undergraduate Curriculum Committee, and numerous other standing and ad hoc committees. Highlights of his service outside BCD include helping design the first promotion and tenure document for the new Texas A&M Health Science Center and his current service on the ADA Anatomic Sciences Test Construction Committee. He has
Although the road to a career as a faculty member in a dental school was not entirely direct, Dr. Hinton found himself in the end in a place where he has enjoyed the interaction with students and colleagues, where the department - in his words has a "congenial atmosphere and is a good size. It's big enough to do significant research but small enough where people have the opportunity to work together." He seems to have no regrets about leaving all that uranium in Oak Ridge.

nuclear effectors that transduce the signals to influence cell fate. The Signaling Pathways in Development and Disease Journal Club provides a forum to discuss recent advances in the field, with an emphasis on craniofacial development, including bone, tooth, neural crest and palate formation. An Endnote library of original papers and reviews has been assembled to provide a framework for selection. The journal club places a premium on communication between participants, in particular, graduate students and postdoctoral trainees. Faculty help guide, but don't exclusively fuel, the discussion of the science.
