Gene expression analysis of 15-Lipoxygenase 2 (15-LOX2) transgenic mice

ABSTRACT: 15-Lipoxygenase 2 (15-LOX2), a human-specific lipid-peroxidizing enzyme, is mainly expressed in luminal compartment of the normal prostate and often decreased or lost in prostate cancer (PCa). Previous studies from our lab implicate 15-LOX2 as a functional tumor suppressor. To better understand the biological role of 15-LOX2 in vivo, we established prostate-specific 15-LOX2 transgenic mice using the ARR2PB promoter. Unexpectedly, 15-LOX2 expression resulted in age-dependent prostatic hyperplasia. Interestingly, transgenic expression of 15-LOX2sv-b, a splice variant that lacks the arachidonic acid metabolizing activity, also induced hyperplasia and enlargement of the prostate. Prostatic hyperplasia induced by both 15-LOX2 and 15-LOX2sv-b was associated with an increase in proliferative (i..
