Changes occur in the sensitivity of the individual lobes of the rat prostate to androgen during aging. These studies provide a fundamental basis for studies of cell proliferation and cell death related to age-dependent alterations in tissue- and cell-specific structure and function associated with carcinogenesis and hyperplasia of the prostate. We are currerntly investigating the regulation of stem/progenitor cell renewal, proliferation and differentiation in the aging prostate. We are particularly interested in how the stromal-epithelial cell microenvironment influences the quiescence and proliferation of stem/progenitor cells relative to the pathogenesis of prostatic hyperplasia in aging rats and men.

A second project focuses upon spermatogenesis and its dependence upon adequate levels of intratesticular androgen, primarily testosterone, and how the androgen receptor mediates the actions of androgens in Sertoli cells. Our goal is to identify and characterize the transcription factors that regulate AR gene expression and other factors that interact with AR to facilitate or repress its activity in the regulation of androgen-dependent genes in the testis.
