Recent studies have suggested that pleural or peritoneal effusion associated with metastatic tumors is induced by some mediators produced by the tumor cells. We studied the ability of well-characterized peptide growth factors to produce ascites in mice. Peritoneal administration of epidermal growth factor (EGF, 10 to 40 micrograms/mouse/wk) or transforming growth factor alpha (TGF-alpha, 10 to ...

Growth factors produced in the uterine endometrium are considered to be involved in the proliferation of the mouse uterine stromal cells induced by estradiol-17beta (E(2)) and progesterone (P). The effect of epidermal growth factor (EGF) and transforming growth factor-alpha (TGF-alpha), one of EGF-related growth factors, on the proliferation of mouse uterine stromal cells was studied in a serum...

The potential of transforming growth factor-alpha (TGF-alpha) to function as an autocrine growth factor was evaluated in numerous ovarian carcinoma cell lines. All 17 lines which were examined expressed the epidermal growth factor receptor and 16 cell lines, in addition, concomitantly secreted TGF-alpha. Radioimmunoassay of processed serum-free-conditioned medium indicated TGF-alpha concentrati...

Carrageenans, a family of polysulphated carbohydrates, inhibited binding of basic fibroblast growth factor (bFGF), transforming growth factor beta 1 (TGF beta 1) and platelet-derived growth factor (PDGF). iota-Carrageenan was the most potent bFGF antagonist (IC50 = 0.4 +/- 0.1 microgram/ml), kappa-carrageenan was the most potent PDGF antagonist (IC50 = 1.7 +/- 1.3 micrograms/ml) and lambda-carr...

The expression of genes which may be involved in the regulation of human mammary epithelial cell growth [transforming growth factors alpha and beta] and tumorigenesis [c-myc, erbB2, epidermal growth factor receptor (EGFR), Ha-ras, pS2] has been compared in similarly cultured normal cell strains and tumor cell lines. We have found that the normal breast cells produce high levels of EGFR mRNA, wh...
