摘要：
A mechanism for survival of prostate cancer cells in an androgen-deprived environment remains elusive Here, we find that expression of neuronal apoptosis inhibitory protein (NAIP) was significantly increased in vivo and in vitro in response to androgen deprivation therapy (ADT). Increased expression of NAIP corresponded to increased DNA-binding activity of NF-kappa B that physically associated to previously uncharacterized kappa B-like sites in the NAIP locus. Importantly, expression of NAIP was significantly increased (p = 0 04) in clinical samples of prostate cancer from patients receiving ADT. Expression of NAIP may be associated with enhanced survival of prostate cancer in response to castration (C) 2009 Elsevier Ireland Ltd. All rights reserved
