E-mail: arul@umich.edu <h3>SPECIFIC AIMS</h3> Our aim was to identify gene expression changes occurring in the human prostate gland at puberty, a crucial juncture in prostate development that is androgen dependent, and to thereby identify novel in vivo targets of androgen action. <h3>PRINCIPAL FINDINGS</h3> Prostate tissues obtained from cadaveric organ donors were grouped into two categories: the pubertal group comprised individuals from 9 to 13 years
