Epidermoid cervical carcinoma cells (CaSki line) have been established in continuous culture. When leukocytes from cervical cancer patients were incubated with CaSki culture fluid concentrates, inhibition of leukocyte migration was observed in more than 70 percent of the patients tested. By contrast, significantly less inhibition was observed with normal(More)
Three fibroblast growth factors (FGFs), acidic FGF (FGF1), basic FGF (FGF2), and keratinocyte growth factor (FGF7) have been identified in prostate. To understand how FGFs regulate growth of the prostate, and to determine if regulation is altered in benign prostatic hyperplasia (BPH), the mitogenic potential of FGFs, receptor binding, and FGF-receptor(More)
Prostatic growth factor (PrGF) was purified from alkaline homogenates of human benign prostatic hyperplastic tissue by a combination of ammonium sulfate precipitation, heparin affinity chromatography, and cation-exchange chromatography. The 17,600-dalton, basic (pI 10.2) PrGF is related to basic fibroblast growth factor (bFGF) since antisera raised against(More)
Homogenates of human testes, epididymides and prostate, and calf testes and epididymides are mitogenic for cultured human foreskin fibroblasts. The growth factors appear similar in that they are inactivated by boiling and acid, but not by treatment with reducing agent. The growth factor in human and bovine testes was partially purified from tissue(More)
Basic fibroblast growth factor (bFGF) has been identified in the human prostate. The level of bFGF has been reported to be elevated in benign prostatic hyperplasia (BPH), compared with normal prostate, suggesting that the growth factor may play a role in this disease of the prostate. Basic FGF is a mitogen for cultured human prostate-derived fibroblasts(More)
Basic fibroblast growth factor (bFGF) and transforming growth factor beta 1 (TGFbeta1) are potential autocrine growth regulators of the prostatic stroma, and therefore may play a role in the development of benign prostatic hyperplasia (BPH). We reported that TGFbeta1 increased bFGF and bFGF mRNA expression in cultured human prostate stromal cells (PS). The(More)
Perfusion of the rat prostatic urethra in vivo provided a means of collecting the rat prostatic secretory product. The secretion of the protein epidermal growth factor (EGF) was investigated by radioimmunoassay (RIA). Baseline secretion of EGF into prostatic fluid was less than .03 +/- .004 SEM ng/min. The alpha-adrenergic agonist phenylephrine caused an(More)
The secretion of human chorionic gonadotropin (hCG) is stimulated by addition of N6, O2′-dibutyryl cyclic 3′:5′-AMP (dbcAMP) or theophylline to normal term placenta and human malignant trophoblast cells in vitro. To understand better the specificity of this process. malignant trophoblast cultures were incubated with 3′:5′-cyclic AMP (cAMP) derivatives,(More)
Basic fibroblast grown factor (bFGF) is a potent mitogen for mesenchymal cells, including fibroblasts cultured from prostate, and has been postulated to play a role in the development of benign prostatic hyperplasia (BPH). If this is the case, it might be expected that bFGF levels would be elevated in the adenomas of BPH and in the periurethral region of(More)
