The GABAB receptor inhibits activation of hepatic stellate cells.


PMID 19229613

Abstract

Angiotensin II (Ang II) plays an important role in the activation of hepatic stellate cells (HSCs). In this study it was found that expression of the GABA(B) receptor was elevated in HSCs treated with Ang II. We attempted to elucidate the mechanism of the GABA(B) receptor in HSCs activation. First, the target gene (GABA(B) receptor) was screened by gene chip in HSCs treated with Ang II. Second, the biological function of the GABA(B) receptor was analyzed by MTT, cell-cycle assay, real-time PCR, and western blot. The methods of MTT and cell-cycle assay were used to evaluate the effect of the GABA(B) receptor on proliferation and DNA synthesis of HSCs. Expression of ECM, TGF-beta1, and alpha-SMA was analyzed by real-time PCR and western blot. The GABA(B) receptor's specific agonist CGP35348 inhibited the activation of HSCs, which could be partially reversed by the GABA(B) receptor's antagonist. Our in-vitro results demonstrated that the GABA(B) receptor could inhibit HSCs activation.
