15-Lipoxygenase 2 (15-LOX2) is the major mammalian lipoxygenase expressed in normal human adult prostate and its expression is decreased or lost in high-grade prostate intraepithelial neoplasia (HGPIN) and prostate cancer (PCa). Our recent work has demonstrated that (1) 15-LOX2 has multiple alternatively spliced isoforms and is a negative cell-cycle regulator in normal human prostate (NHP) epithelial cells; (2) 15-LOX2 in NHP cells is positively regulated by Sp1 and negatively regulated by Sp3; (3) 15-LOX2 in NHP cells may be partially involved in cell differentiation; (4) 15-LOX2 is cell-autonomously upregulated in cultured NHP cells and its induction is associated with NHP cell senescence; and (5) 15-LOX2 is a functional prostate tumor suppressor. Here we summarize these new findings to provide a concise view of the potential biological functions of 15-LOX2 in NHP cells and of its deregulation in PCa development.
