Glycogen synthase kinase3 (GSK3α and GSK3β) are serine/threonine protein kinases acting on numerous substrates and involved in the regulation of various cellular functions such as their proliferation, survival, glycogen metabolism, and autophagy. Accumulating evidence indicates that the expression of GSK3α is increased mainly in androgendependent while that of GSK3β in androgenindependent prostate cancer, and that GSK3β is also involved in the regulation of the transactivation of the androgen receptor (AR) and growth of prostate cancer. Animal experiments have proved that some GSK3 inhibitors, such as lithium, can significantly suppress tumor growth in different animal models of prostate cancer.

Aim: To determine the role of Notch1 and Hes1 in regulating the activation of hepatic stellate cells (HSCs) and whether Hes1 is regulated by transforming growth factor (TGF)/bone morphogenetic protein (BMP) signaling.

Methods: Immunofluorescence staining was used to detect the expression of desmin, glial fibrillary acidic protein and the myofibroblastic marker α-smooth muscle actin (α-SMA) after freshly isolated, normal rat HSCs had been activated in culture for different numbers of days (0, 1, 3, 7 and 10 d). The expression of α-SMA, collagen1α2 (COL1α2), Notch receptors (Notch1-4), and the Notch target genes Hes1 and Hey1 were analyzed by reverse transcriptase-polymerase chain reaction.
