    Current Research and Scholarly Interests Telomeres are nucleoprotein complexes that protect chromosome ends and shorten with cell division and aging. We are interested in how telomere shortening influences cancer, stem cell function, aging and human disease. Telomerase is a reverse transcriptase that synthesizes telomere repeats and is expressed in stem cells and in cancer. We have found that telomerase also regulates stem cells and we are pursuing the function of telomerase through diverse genetic and biochemical approaches.

    Professor of Biochemistry, Emeritus

    Current Research and Scholarly Interests I closed my laboratory when I retired in 1998. I continue to do research, chiefly in collaboration with Franc Avbelj, on problems of protein folding energetics, especially peptide backbone solvation, and to write reviews.

    The Ernest and Amelia Gallo Professor in the School of Medicine and Professor of Developmental Biology

    Current Research and Scholarly Interests Function of Hedgehog proteins and other extracellular signals in morphogenesis (pattern formation), in injury repair and regeneration (pattern maintenance). We study how the distribution of such signals is regulated in tissues, how cells perceive and respond to distinct concentrations of signals, and how such signaling pathways arose in evolution. We also study the normal roles of such signals in stem-cell physiology and their abnormal roles in the formation and expansion of cancer stem cells.

    Current Research and Scholarly Interests For about 10 years until 2000, my lab's research activities were focused on the mechanism of recombinational repair of double-strand breaks in DNA. We focused our efforts on two model systems: one involved the repair of restriction enzyme cleavages at specific mammalian chromosomal loci and the second explored the biochemical properties of purified yeast Rad51 protein, an essential catalyst for synapsing the broken ends of DNA with an intact homologue of that sequence. We also explored the roles of Rad52 and PRA (single-strand DNA binding protein) in the repair process.

    In 2000, I became Emeritus Professor in Biochemistry and stepped down from the Directorship of the Beckman Center. Much of my activities since then have been involved in writing a biography of the genetics pioneer George Beadle, published in 2003, plus articles for other publications elaborating on Beadle's legacy for today's science. Over the years I have been and continue to be an activist in public policy issues affecting biomedical issues, e.g. recombinant DNA and more recently, issues concerning embryonic stem cells.

  • Onn Brandman

    Onn Brandman

    Assistant Professor of Biochemistry

    Current Research and Scholarly Interests The Brandman Lab studies how cells ensure protein quality and how they signal stress. To achieve this, we employ an integrated set of techniques including single cell anaysis of stress pathways, structural studies, in vitro translation, and full genome screens in yeast and mammalian cells.

  • Patrick O. Brown

    Patrick O. Brown

    Professor of Biochemistry

    Current Research and Scholarly Interests Dr. Brown's research group uses diverse experimental and computational methods to investigate the logic and mechanisms that control a genome's expression program. The Brown laboratory is systematically characterizing the genetic scripts that control the expression of our genes, in normal development and physiology and in diseases like cancer, with a particular focus on post-transcriptional regulation. The Brown lab also develops strategies and assays for early detection and diagnosis of cancer.

  • Douglas L. Brutlag

    Douglas L. Brutlag

    Professor of Biochemistry, Emeritus

    Current Research and Scholarly Interests My primary interest is to understand the flow of information from the genome to the phenotype of an organism. This interest includes predicting the structure and function of genes and proteins from their primary sequence, predicting function from structure simulating protein folding and ligand docking, and predicitng disease from genome variations. These goals are the same as the goals of molecular biology, however, we use primarily computational approaches.

  • Gilbert Chu

    Gilbert Chu

    Professor of Medicine (Oncology) and of Biochemistry

    Current Research and Scholarly Interests Our laboratory focuses on understanding how cells respond to DNA damage. Our research currently involves areas that interact with each other: repair of radiation damage, and transcriptional responses to DNA damage.

  • Rhiju Das

    Rhiju Das

    Assistant Professor of Biochemistry

    Current Research and Scholarly Interests Our lab seeks an agile and predictive understanding of how nucleic acid and protein codes underlie the activities of living systems. We are creating new computational and chemical tools to tackle the de novo modeling of protein and RNA puzzles, the biophysics of functional and random RNAs, and the design of new RNA shapes and switches.

    Professor of Biochemistry and of Genetics

    Current Research and Scholarly Interests We are using Saccharomyces cerevisiae and Human to conduct whole genome analysis projects. The yeast genome sequence has approximately 6,000 genes. We have made a set of haploid and diploid strains (21,000) containing a complete deletion of each gene. In order to facilitate whole genome analysis each deletion is molecularly tagged with a unique 20-mer DNA sequence. This sequence acts as a molecular bar code and makes it easy to identify the presence of each deletion.
