Human adrenomedullin up-regulates interleukin-13 receptor alpha2 chain in prostate cancer in vitro and in vivo: a novel approach to sensitize prostate cancer to anticancer therapy.
In castrated animals, intraperitoneal injection of AM resulted in a 240+/-18% (P<0.001) increase in tumor volume 36 days after treatment, indicating that the nature of effect of AM in CaP depends on the presence or absence of endogenous androgen.
To elucidate the potential role of the AM gene in prostate cancer progression, we have stably-transfected the PC3 human prostate cancer cell line with an AM gene expression vector.
