Differential effects of Hsc70 and Hsp70 on the intracellular trafficking and functional expression of epithelial sodium channels.

abstract：:Studies of prostate cancer pathogenesis and development of new therapies have been hampered by a lack of appropriate mouse models. We have generated PSA-Cre-ER(T2) mice that express the tamoxifen-dependent Cre-ER(T2) recombinase selectively in prostatic epithelium, thus allowing us to target floxed genes selectively i...
