Tissue distribution and potential alternative splicing of insulin-like growth factor I (IGF-I) messenger RNA were studied using reverse transcriptase-polymerase chain reaction (RT-PCR) on RNA from several tissues at various stages of the life cycle of coho salmon (Oncorhynchus kisutch). DNA sequence analysis of RT-PCR products revealed three IGF-I mRNA(More)
This study investigated the cytotoxic effect of zinc-citrate compound (CIZAR) on choriocarcinoma cell lines. Primary cultured normal trophoblast cells (NPT), human tumorigenic poorly differentiated trophoblast cell line (HT), and choriocarcinoma cell line (BeWo) were exposed to different concentrations of CIZAR and cultured at different times.

Transforming growth factor-beta 1 (TGF-beta 1) and androgen are potential physiological regulators of prostate cancer cells. In the present study, we have used LNCaP cells as a model of androgen-responsive prostate cancer to investigate the effects of dihydrotestosterone (DHT) on the sensitivity to TGF-beta 1. The ability of LNCaP cells to respond to(More)
Of the three ubiquitously expressed transforming growth factor-beta (TGF beta) receptors, only type I and type II receptors contain serine/threonine kinase activity and have a direct role in TGF beta signal transduction. In the prostate, it has been reported that the level of type III receptor expression increases transiently after castration. However, the(More)
mST3GalV synthesizes ganglioside GM3, the precursor for simple and complex a- and b- series gangliosides, and the expression and regulation of mST3GalV (CMP-NeuAc: lactosylceramide alpha2,3-sialyltransferase) activity is central to the production of almost all gangliosides, a class of glycosphingolipids implicated in variety of cellular processes such as(More)
