Abstract

Inhibition of apoptosis is a critical pathophysiological factor that contributes to the development of prostate cancer. Recently, PAX2, a transcriptional regulator implicated in oncogenesis, has been demonstrated to be expressed by prostate cancer. However, its downstream molecular pathways for suppression of apoptosis, other than the tumor suppressor gene p53, have yet to be elucidated. Here, we examine the effects of inhibiting PAX2 expression by prostate cancer cells that differ in p53 gene status. These data collectively demonstrate that PAX2 inhibition results in cell death independent of p53, and that additional tumor suppressors or cell death pathways may be inhibited by PAX2 in prostate cancer cells.
