Sponsored by: the Office of Biomedical Research, Education and Training (BRET) PAGE 2 Neuroscience Program by Jessica Moore Karoly Mirnics, in collaboration with David Lewis at the University of Pittsburgh and Pat Levitt, recently published a paper in Biological Psychiatry titled "Molecular Evidence for Increased Expression of Genes Related to Immune and Chaperone Function in Prefrontal Cortex in Schizophrenia." This microarray study demonstrates that mRNAs for eleven genes involved in the response to infection are increased in schizophrenia patients. The study of schizophrenia's complex etiology benefits from methods that do not require defined hypotheses, such as gene expression profiling. This method reveals novel connections between this mental disorder, which affects ap- proximately one percent of the population, and gene networks and has previously identified changes in expression of genes in the GABA and glutamate systems, in oligodendrocytes, at synapses, and in mitochondria. These studies, and the newly published research, examine gene expression in the prefrontal cortex because of the centrality of functions requiring this area, such as working memory and goal-directed behavior, to schizophrenia (Lewis DA and Mirnics K, Progress in Brain Research 2006). This study minimizes confounds common to microarray research, allowing replicable conclusions. The design of the custom-made microarray decreases cross-hybridization and its impact on the results. Further, the gene expres- sion changes reported meet significance requirements when analyzed four different ways. Expression of 67 genes differs between the schizophrenia samples and controls, including 45 downregulated and 21 upregulated transcripts, many confirming previous findings. Most importantly, clustering analysis reveals that upregula- tion of eleven of the genes, all of whose functions are immune or chaperone (to prevent protein aggregation in re- sponse to cellular stress), is strongly correlated and that a subset of schizophrenic subjects contribute to their signifi- cance. This study provides cortical gene expression evidence for the neuroimmune hypothesis of schizophrenia, so far based on epidemiological, serological, and pathological data (Rothermundt et. al., Brain, Behavior, and Immunity 2001). The increased expression of these genes might represent either a response to a chronic infection or an autoimmune condition, or permanent damage from an earlier infection or immune challenge, possibly during brain development. The authors favor the latter interpretation because expression of markers of acute immune response are similar be- tween groups and prenatal exposure of rodents to maternal immune response has previously been shown to cause behavioral and pathophysiological effects similar to schizophrenic symptoms (Ozawa et. al., Biological Psychiatry 2006, Zuckerman et. al., Neuropsychopharmacology 2003). Further, the researchers speculate that early-life elevation of in- "researchers...have flammatory cytokines in the brain causes symptoms of schizophrenia both by altering development of brain circuits and by continuing to affect cognitive function through increased immune gene expression throughout life. unambiguously Karoly Mirnics, MD, (firstname.lastname@example.com) joined the faculty of the Graduate Program in Neuroscience, the Kennedy Center for Research on Human Development, and the Department of Psychiatry at Vanderbilt in 2006. identified a genetic Pat Levitt, Ph.D. (firstname.lastname@example.com) is a Vanderbilt faculty member in the Department of Pharmacology and Neuroscience Program, and is the Director of the Kennedy Center for Research on Human Development. variant...that is associated with an increased risk for Human Genetics Department by Stephen Turner Several groups of human genetics researchers in the United States and abroad, including Jonathan Haines's group in the Center for Human Genetics Research here at Vanderbilt University, have unambiguously identified a genetic variant developing in the interleukin 7 receptor (IL7R) that is associated with an increased risk for developing multiple sclerosis, a neurode- generative disorder that afflicts over a quarter million Americans. multiple sclerosis" These findings, published simultaneously in Nature Genetics and The New England Journal of Medicine on July 29 repre- sent the first major discovery in MS genetics in 30 years. Researchers have known for quite some time that MS has a strong genetic component that has remained elusive until now. "The effect of a single genetic variant is not overwhelm- ing," said Jonathan Haines, senior corresponding author on the Nature Genetics paper, in an interview. "The techniques that worked well for identifying genes causing Mendelian genetic disorders do not work well for more common, complex diseases," remarked Haines. Although there is certainly a strong genetic element that increases risk of developing MS, the genetic effect is subtle, and more sophisticated techniques are needed to identify the genes involved. When asked to comment on the implications of this finding for future MS treatment and research, Haines remarked that this discovery would not lead to any immediate changes in the way MS patients are treated, but that researchers would now better know where to focus their studies. One of the most important questions raised by this finding is de- termining the significance of variation in the soluble to membrane-bound isoform ratio of the receptor, which is caused by this variant in IL7R. Once this is answered, researchers may be able to rationally design drugs that target constituents in the IL7R pathway. Haines also noted that this study would not have been possible without an interdisciplinary approach. "This would have been impossible without our collaboration with clinicians who make accurate diagnoses, specialists in ascertainment and sample collection, molecular geneticists, and statisticians with analytical expertise." As for ongoing research, the genetic basis of MS is far from being fully explained. The variant described in these stud- ies does not by itself cause MS – it only increases one's risk of developing MS. The variant is quite common, and many individuals inherit the variant but never develop symptoms of MS. It is unclear whether the product of this gene interacts with other genes, environmental factors, or both. As part of her Ph.D. thesis research, Rebecca Zuvich, a third year graduate student in the Haines lab, will be examining other genes in the IL7R and related pathways to see if variation in any of these genes will allow us to more completely explain the genetic basis of MS. Jonathan Haines, Ph.D. (email@example.com) is a faculty member at Vanderbilt in the Departments of Molecular Physiology and Biophysics and Human Genetics, and is the Director of the Center for Human Ethics Research. PAGE 3 Cell and Developmental Biology Department by Lindsay Bramson In the first issue of ABSTRACT, the department of Cell and Developmental biology (CDB) column will profile the two new faculty mem- bers that have joined the department this year. Melanie Ohi and Ryoma (Puck) Ohi began their scientific journey at Vanderbilt as graduate students in the lab of Kathy Gould and are now returning to start their own labs. Dr. Melanie Ohi's lab, located on the third floor of MRBIII, will be studying two major complexes: the spliceosome, which she has studied in both her graduate and post-doctoral training, and the Anaphase Promoting Complex (APC/C). In order to further understand the spli- ceosome, splicing complexes will be isolated during different stages of the splicing process and characterized both structurally and biologi- cally in S. pombe. Studies on the APC/C will be centered around the isolation of its components and characterization of its structure. Graduate students who would like to join Melanie's lab will study these structures with an integrated approach, utilizing biochemistry, genet- ics, and structural biology. First-year students who wish to rotate here will begin the initial characterization of one of the components from the spliceosome or APC/C and observe how the cryo-electron microscope is utilized for these projects. Dr. Puck Ohi's laboratory, also located on the third floor of MRB III, will identify and study substrates of the protein kinase Aurora B to better understand its function(s) during mitosis. In collaboration with an investigator at Colorado State University, alanine and phosphomi- metic mutants of the known Aurora B substrate Hec1 will be utilized to examine the function of Hec1 phosphorylation at the kinetochore. Studies will also examine whether the activities of Kif18a, a microtubule depolymerizing kinesin whose function is required for normal chro- mosome dynamics during metaphase (Figure below), are controlled by Aurora B-catalyzed phosphorylation. The third focus of Puck's re- search concentrates on identifying the phosphatase that antagonizes Aurora B activity. Students rotating in Puck's laboratory can pick a project based on their scientific and technical interests. One potential project will use live cell imaging to investigate the consequence of removing KIF18a on the accuracy of chromosome segregation during anaphase. Another potential rotation project is to assess the effect of removing the phosphatase PP6 from Xenopus egg extracts on spindle assembly. Graduate students interested in learning more about either of these labs may contact Melanie at email@example.com and Puck at firstname.lastname@example.com. Functional consequences of KIF18a siRNA. HeLa cells were transfected with either control or KIF18a siRNAs. Forty-eight hours later, cells were fixed and processed for immunofluorescence using either CREST (red) or anti-tubulin (green) antibodies to detect kinetochores and microtubules, respectively. Chromosomes in control cells are aligned at the metaphase plate and have robust kinetochore fibers. In contrast, chromosomes in KIF18a- cells fail to congress and are attached to weakly developed kineto- chore-fibers.

This PAGE 4 Pathology Department by Robin Marjoram Over the last few years, the Department of Pathology has grown in all areas it encompasses, including its investi- gative programs in vascular biology and cancer biology. Recently, the cancer biology program was fortunate enough to recruit two new faculty members to the department and Vanderbilt University: Christine Eischen, Ph.D. and An- dries Zijlstra, Ph.D., who have started exciting research programs in lymphoma pathobiology and tumor cell invasion and metastasis, respectively. Dr. Eischen obtained her Ph.D. in Immunology from the Mayo Clinic in Dr. Paul Leibson's lab, did a postdoctoral fellowship at St. Jude Children's Research Hospital in the lab of Dr. John Cleveland, and then joined the Eppley Insti- tute for Research in Cancer at the University of Nebraska as an Assistant Professor. In November 2006, she moved her lab to Vanderbilt University to continue her research on genes that regulate B cell lymphoma development by affecting known tumor suppressor and oncogenic pathways. Dr. Eischen's lab has demonstrated that progression to B cell malignancy is accelerated when there are alterations in the tumor suppressors p53 and ARF. Alternatively, a deficiency in the oncogene Mdm2 results in the suppression of lymphoma development. A manuscript on this topic is currently in press (Wang P., et al., 2007, Oncogene) showing that elevated Mdm2 expression induces chromosomal instability and confers a survival and growth advantage to B cells. The lab has other studies underway to further characterize these findings and elucidate novel pathways that regulate transformation. Results from these studies will provide a better understanding of the genes and pathways that regulate tumorigenesis and cancer development, which will lead to improved therapeutics for human lymphomas and other malignancies. Dr. Zijlstra obtained his Ph.D. in Genetics and Cell Biology from Washington State University. Prior to coming to Vanderbilt, he conducted research at the Italian National Institute for Cancer Research in Genova and the Scripps Research Institute. He chose Vanderbilt as the institution to start his lab because it offered a highly collaborative environment and the Department of Pathology lends itself to translational research. Dr. Zijlstra's research is primar- ily focused on the metastatic dissemination of tumor cells and the contributing molecular processes, with particular interest in migration and invasion by utilizing the chicken embryo as a model organism. Their recent work has fo- cused on the role of CD151, a tetraspanin whose function is poorly understood. They believe that this molecule can control migration by regulating detachment at the rear of the cells, since promoting immobility through CD151 re- "New, duces metastasis by more than 90%.

New, groundbreaking research in the study of autism is evolving the under- standing of the disorder's genetic and genomic basis, says Jim Sutcliffe, Ph.D, associate professor in the department of genetic and Molecular Physiology and Biophysics. Dr. Sutcliffe is a member of the Autism Genome Project Consortium (AGPC), a worldwide collaboration of autism genomic basis." researchers. Recently the AGPC published an article in Nature Genetics (vol. 39, no. 3, March 2007) examining ge- nomic anomalies in families containing 2 or more subjects with autism spectrum disorders (ASDs). The study included over 1400 affected families from all over the world, and is to date the largest collection of families ever studied in autism research. Instead of looking at the risk conferred by specific genes, studies of this scope are examining which networks of genes are important and are common throughout autistic populations. Using cohorts of this size is es- sential in order to overcome the complex heterogeneity of these disorders and allowed the authors to use a combina- tion of approaches to increase the power of their findings. In the AGPC study, after each subject was genotyped, the authors used the intensity of the signal from the SNP array to infer the copy number of an individual, relative to the other samples. Copy number variations (CNVs) refer to changes in DNA sequence that occur in individuals, and are an increasingly-common tool in genetic research. CNVs can be inherited, occur sporadically, or be mixed. The sites of these CNVs can then be used as putative risk loci for ASDs, and also as a sorting mechanism to reduce genetic heterogeneity for linkage studies. Finally, linkage analysis was used to find genomic regions of interest that may increase the risk of autism in families. The group's findings have significantly changed the way researchers are approaching the study of the genetic bases for ASDs. Most importantly, using linkage studies based on the CNV analysis, this study identified a specific area of the genome, chromosome 11p13, as highly significant in conferring risk for autism. More generally, however, it showed that CNVs are important for the risk of autism at a global, population-wide level- a genomic, not just genetic, risk. Dr. Sutcliffe and other AGPC researchers hope this type of finding will shift the focus of the field from looking primarily at candidate genes and linkage studies to piecing together the broader scope of genetic variations that under- lie autism disorders. Dr. Jim Sutcliffe, Ph.D (firstname.lastname@example.com) is a faculty member in the Departments of Psychiatry and Molecular Physiology and Biophysics at Vanderbilt.

These talented minds are anxious to continue their training, and many desire to make the move from academia to industry. However, this move is often constrained by geography; Ten- nessee does not possess the huge variety of biotechnology and pharmaceutical opportunities that are abun- dant in areas like southern California, Boston, or Research Triangle Park. But for young professionals who are nurturing careers as well as the responsibilities of their personal lives, such a move may be difficult. Are there any opportunities for young scientists in the Volunteer State? Nashville and middle Tennessee: Well within the comfort zone for Vanderbilt trainees is the nearby Cool Springs Life Sciences Center (CSLSC) in Williamson County. This $74 million, 10-acre campus was designed attract biotechnol- ogy and bioscience companies to the area. The first of the three buildings on campus is completed and is occupied by several organizations that may provide opportunities for scientists. In addition to Vanderbilt's continued involvement in the project, the campus is home to the Williamson Office of Economic Develop- ment and its Knowledge Quest Institute to foster the development of a knowledge-based economy and the workforce to staff such endeavors. The bench-science space at CSLSC is occupied by BioMimetic Theraputics, Inc. This growing company focuses on the development of drug-device combination products, most notably their product for the treatment of bone and tissue loss due to periodontal disease. At the time of publication, BioMimetic Theraputics featured advertisements seeking scientists and research associates skilled in immunology, pro- tein chemistry, and clinical research. With two additional, larger facilities under development, CSLSC may prove to be a valuable asset for scientists seeking to remain in middle Tennessee while still progressing in their careers. "Scientists looking East Tennessee: to stay in The most well-know research center in East Tennessee is the Oak Ridge National Laboratory.

Networking and finding more opportunities: Scientists looking to stay in Tennessee may have to work harder or be more creative about find- ing opportunities and making career connections. Local organizations to foster education and biotechnol- ogy, such as Memphis BioWorks Foundation and Tennessee Biotechnology Association, can aid in this net- working. These organizations bring together scientists and non-scientists interested in increasing the bio- technology presence in Tennessee. Many directors of the major biotechnology companies in the area are highly involved in these organizations, providing a valuable link to the newest opportunities and develop- ments in the area.

PAGE 8 A LETTER FROM THE EDITORS Dear Vanderbilt Community, We hope that you found the inaugural issue of ABSTRACT to be both informative and thought-provoking. As students ourselves, we feel that it is important for developing sci- entists to stay informed of not only progress in our respective fields but also important issues in the societal, legislative, and economic environment in which we approach our sci- entific pursuits. Our goal in establishing this student and postdoctoral publication is three- fold: to inform readers about a variety of important developments in the realms of science, business and government to maintain trainees' intellectual connections with all biomedical departments, in keep- ing with the interdisciplinary goals of biomedical education at Vanderbilt. to provide Vanderbilt students and postdoctoral fellows with an opportunity to gain experience in science writing We hope that you will look to ABSTRACT for coverage of current progress at Vanderbilt and in the broader scientific community and that the information provided here will spark discussion and debate among colleagues. Finally, we would like to thank the Office of Biomedical Research, Education and Training (BRET) and, more specifically, Drs. Roger Chalkley and Kim Petrie for their support. We would also like to thank our writers, whose talent and investment have shaped our first issue and made ABSTRACT a reality. It is our sincere hope that ABSTRACT will become a staple of the student and postdoctoral experience at Vanderbilt, and thus we encourage you to contact us with your questions and comments.
