Calcineurin (CN), a Ca2+/calmodulin-regulated phosphatase 2B, plays an important role in many biological processes including T-cell signal transduction. In the present study, the distribution and activity of CN were investigated in rat tissues. CN has a wide tissue distribution, as measured by enzyme-linked immunosorbent assay. CN concentrations are 0.2-0.6(More)
Aberrant activation of the signal transducer and activator of transcription (STAT) 3 occurs in many human tumors. Constitutive STAT3 activity induces specific target genes that stimulate cell proliferation, prevent apoptosis, promote angiogenesis and facilitate tumor immune evasion. Thus, STAT3 is an attractive molecular target for the development of novel(More)
Simvastatin is a cholesterol-lowering drug which exhibits numerous pleiotropic effects including anti-cancer activity. Yet, the anti-cancer effects in choroidal melanoma remain poorly characterized. Therefore, in this study, we investigated the effects of simvastatin on OCM-1 cells growth, apoptosis and cycle. Simvastatin showed an inhibitory effects on(More)
