Terazosin treatment suppresses basic fibroblast growth factor expression in the rat ventral prostate.

Purpose: Alpha1-adrenergic receptor antagonists may not act solely on smooth muscle contractility. We evaluated the in vivo effect of the alpha1 blocker, terazosin, on the expression of basic fibroblast growth factor (bFGF) in the rat ventral prostate.

Methods: Wistar rats were treated with terazosin (1.

Expression of transforming growth factor beta in renal cell carcinoma and matched non-involved renal tissue.

TGFbeta1 is one of several cytokines produced by proximal tubular and renal cancer cells. Previous studies have been mainly focused on determining plasma or serum TGFbeta levels, its effect on RCC cultures, and the expression of TGFbeta mRNA. Cancerous and autologous normal kidney samples were obtained from 24 patients treated by radical nephrectomy.
