Regulation of Cell Cycle and Tissue-Specific Genes Controlling Proliferation and Differentiation in Biological Control and Cancer

The central theme of our research program has been to discover mechanisms controlling proliferation and differentiation in mammalian cells with emphasis on compromised regulation that is linked with disease.  We pioneered characterization of transcriptional regulation that mediates cell cycle control.  The laboratory is investigating molecular mechanisms regulating gene expression that controls competency for cell cycle progression at the G1/S phase transition in normal and tumor cells and for an abbreviated pluripotent cell cycle in human embryonic stem cells.  A second field in which our laboratory is making a major impact is skeletal biology, where we established the foundation for addressing bone tissue specific gene expression.  Current initiatives include microRNA-mediated control and molecular, cellular, biochemical and in vivo genetic parameters of skeletal development and bone remodeling, aberrations that accompany the onset and progression of skeletal disease, as well as perturbations related to breast and prostate cancer metastasis to bone.  Our research group has been instrumental in defining functional relationships between subnuclear organization of regulatory proteins and gene expression.  We have made important contributions to mechanisms that support combinatorial organization and assembly of regulatory machinery for gene expression in nuclear microenvironments and epigenetic control of cell fate and lineage commitment in biological control and cancer.  The architectural parameters of regulatory networks that are obligatory for fidelity of gene expression are being clarified as a basis for therapeutic strategies with high specificity and reduced off target effects.

Postdoctoral Position Available Cell Cycle and Tissue-Specific Transcriptional Control Postdoctoral position available to investigate transcriptional regulation of cell cycle and tissue-specific genes. Emphasis is on developmental, growth factor and steroid hormone responsive control of proliferation and differentiation in normal and tumor cells. We are actively pursuing functional interrelationships between nuclear architecture (chromatin structure, nucleosome organization and the nuclear matrix) and expression of cell cycle and phenotype restricted genes (see Vaughan et al., Nature 377:362-365; Zeng et al., PNAS 94:6746-6751; Guo et al., PNAS 94:121-126).
