 We are using genomic approaches for analyzing transcriptional programs and mechanisms in eukaryotic cells. One area of research involves the use of DNA microarrays to map the genome-wide, in vivo DNA binding distribution of a variety of transcription factors in yeast. Genes regulated by such transcription factors are identified by analyzing global changes in gene expression in response to modulation of the given factor. Another interest is the study of transcriptional control mechanisms in cellular proliferation and cancer biology. The expression of several transcription factors is altered during the transition of human cells from quiescence to proliferation. We are using human cDNA microarrays containing tens of thousands of human genes to identify genes involved in proliferation and to determine the downstream targets of oncogenic transcription factors.
