UCLA Genomic Analysis Training Program: Faculty
The UCLA faculty Genomic Analysis and Interpretation Training Program are organized into six research areas. Trainees working with these faculty are, of course, not limited to these research areas. Neither are trainees limited to these faculty. Potential additional faculty are urged to contact the Training Program Directors.
Laboratories at UCLA are on the forefront of developing many of the technologies that will be used in future genomic research. These technologies range from microarrays to positron imaging. Students trained by faculty in this area are expected to gain insight into potential applications of the latest technologies, to apply them to solve problems in genetics, and to develop novel technologies themselves.
Arnold Berk studies molecular interactions that regulate transcription in mammalian cells, in particular transcription factors encoded by oncogenes and tumor suppressors and the regulation of cell replication. He studies proteins expressed early during infection by DNA viruses because these proteins interact with key host cell regulatory proteins such as p53, the Retinoblastoma protein family, the mediator of transcription complex, and chromatin modifying complexes. He also studies inactivation of the p53 tumor suppressor by adenovirus E1B. His work can explain how all p53 molecules are inactivated when only ~1% are modified by SUMO1. He applies "ChIP on chip" methodology to discover how the adenovirus small e1a protein forces contact-inhibited human cells to proliferate: small e1a directly re-localizes major chromatin-modifying complexes on a global genomic scale. He also works in the area of gene therapy: he engineered an adenovirus-Epstein-Barr virus hybrid vector that introduces stable episomes into infected cells in tissues of intact animals. [website]

Steve Young's research has demonstrated the in vivo importance of the post-translational modifications of isoprenylated proteins. Another focus of his laboratory has been gene-trapping in embryonic stem (ES) cells. Over the past five years Dr Young has led BayGenomics, an NHLBI-funded gene-trapping consortium involving investigators from UCSF and UCLA. BayGenomics uses gene-trapping techniques to randomly inactivate genes in mouse embryonic stem cells. One of the other goals of BayGenomics is to identify new genes that are relevant to cardiopulmonary development and disease. Dr Young has used BayGenomics ES cells to create knockout mice lacking several triglyceride biosynthetic enzymes. These knockouts permit identification of genes responsible for triglyceride synthesis in mammary epithelium, brown adipose tissue, skin, and cartilage. [website]
Model organisms have been applied very successfully by participating faculty at UCLA in identifying genes contributing to heart disease and psychiatric disorders. Several disease predisposing genes have been cloned, and a unique resource of genome tagged mice is available for mapping new genes and testing their interactions. Because animal models are proving crucial to mapping genes for complex traits, students working with faculty in this area will be well positioned for future careers in either mouse or human genetics.
Esteban C. Dell'Angelica's laboratory conducts research aimed at understanding (1) the molecular basis for protein trafficking and organelle biogenesis within the endosomal/lysosomal system and (2) how defects in these processes can lead to human disease. Current efforts are focused on a small group of genes associated with schizophrenia or Hermansky-Pudlak syndrome (HPS), of which model mutant mice and flies have arisen through spontaneous mutations or created by targeted gene disruption. Studies using these mutant model organisms are complemented with biochemical and functional characterization of the gene products in vitro and in cultured cell lines. [website]
Katrina Dipple's research focuses on understanding the complexity of simple Mendelian disorders. Her laboratory investigates how genetic variation causes human disease and how single gene mutations are affected by the other genetic mutations and polymorphisms in the genome, using glycerol kinase deficiency as a model. Dr Dipple also studies the complexity and interconnectivity of metabolic genetic diseases. Her laboratory uses human and animal models in combination with molecular biology techniques and metabolic engineering concepts (including metabolic flux analysis, network component analysis, and mathematical modeling of protein functions) to unravel these complex interactions and networks.

Specific questions that he has addressed in his research include: how genes organized in the genome, what are the mechanisms that control the regulation of plant gene expression, what are the sequences that program plant gene expression during development, what are the genes that control the differentiation of specific plant cell types, and what events cause an undifferentiated cell to take on a specialized state. He is a member of the seed institute, a collaborative effort to understand the genes and processes required to "make a seed." [website]
Aldons (Jake) Lusis has studied many complex genetic diseases and associated traits, particularly those tied to atherosclerosis and its risk factors. It is now clear that these traits can be attacked by quantitative trait locus (QTL) mapping using inbred animal strains. Thus far, Dr Lusis and his colleagues have identified murine loci contributing to cholesterol metabolism, obesity, and arterial inflammation. The major challenge is to understand the action of these disease genes at the molecular level. Dr Lusis is a well-respected teacher and mentor at UCLA. His 17 former doctoral students hold research positions in industry and faculty appointments at several major research universities. He is currently mentoring one postdoctoral and nine predoctoral students. [website]

His laboratory also uses whole genome comparative analyses across species to gain insight into the evolution of molecular mechanisms required for stem cell formation and maintenance. [website]
Karen Reue has used naturally occurring mutations in mouse models to identify genes important in human metabolic diseases. With this approach, her group has discovered a novel gene known as lipin, which is associated with obesity and diabetes, and a second novel gene that protects against high cholesterol levels and atherosclerosis. She is currently working to elucidate the function of these genes and their potential role in human disease using a combination of cell and molecular biology, transgenic and knockout mouse models, and studies in human subjects. [website]
Desmond Smith is interested in understanding how the genome constructs the brain in both health and disease. He has developed technologies for genome-scale acquisition of expression patterns in the brain. These methods, voxelation and gene expression tomography, survey both the transcriptome and proteome and combine the mathematical concepts of biomedical imaging with the high-throughput analytic tools of genomics. He is also employing genetic mapping to identify loci influencing behavior in the mouse. His ultimate goal is to decode how the conceptual wiring diagram of the genome gives rise to the neuronal wiring diagram of the brain. Dr. Smith was named to the "Scientific American 50" in 2008.

Michael Alfaro studies the factors that govern the evolutionary dynamics of organismal diversification. In particular he is interested in why are some groups morphologically diverse, whether there are general laws or themes that can be used to explain the uneven distribution of diversity in physiological traits across lineages and whether morphological diversity always signal mechanical, functional, or ecological diversity. His research approach is interdisciplinary and quantitative and crosses traditional boundaries among evolutionary morphology, molecular phylogenetics, and theoretical evolution. [website]
David Eisenberg and his colleagues in the UCLA DOE Laboratory of Structural Biology and Molecular Medicine are assessing sequence and folding patterns that contribute to heat stability in proteins of extreme thermophiles. The DOE Lab plans to determine the 3D crystallographic structure and function of as many members as possible of the proteome of the thermophilic microbe, Pyrobaculum aerophilum. Over the past decade, Eisenberg's interests have increasingly focused on structural genomics and computational biology. Following a thread of discovery from his earlier work on sequence families and assignment of protein sequences to 3D folds, he is now concentrating on assigning genome sequences to biological functions. His new methods depend on correlated inheritance of proteins in species; correlated fusion of domains into single protein chains; and correlated mRNA expression patterns. Dr Eisenberg is a member of the US National Academy of Science and the Howard Hughes Medical Institute. He has mentored over 100 students, many who have gone on to significant careers in genomics.

Marc Suchard is helping to develop the nascent field of evolutionary medicine. This field harnesses the power of methods and theory from evolutionary biology to advance our understanding of human disease processes. Just as phylogenetic approaches have stimulated the field of evolution at large, they posses the potential to revolutionize evolutionary medicine, particularly in the study of rapidly evolving pathogens. To bridge the gap between phylogenetics and human-pathogen biology, Dr Suchard's interests focus on the development of novel reconstruction methods drawing heavily on statistical, mathematical and computation techniques. Some of his current projects involve jointly estimating alignments and phylogenies from molecular sequence data and mapping recombination hot-spots in the HIV genome. [website]
