Promotes Hepatocyte Proliferation Via NF-κB and ERK Pathway by Targeting , and

Phospholipase Cγ2 (PLCG2) has been implicated in the regulation of cell proliferation, transformation, and tumor growth. In this study, we investigate the mechanism of action using a short interference RNA (siRNA) method. The effects of on rat liver BRL-3A cells treated siRNA were studied by 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide (MTT assay), bromodeoxyuridine (BrdU) labelling assay, flow cytometry method (FCM), quantitative real-time polymerase chain reaction (qRT-PCR) and western blot. The results showed when PLCG2 was reduced, cell vitality and proliferation rate were significantly decreased ( < .05 vs. control). FCM analysis showed that the number of cell division phase (G2 + M) was declined ( < .05 vs. control). RT-PCR and western blot revealed that the expression of signalling related genes and target genes and were remarkably down-regulated in cells treated with PLCG2 siRNAs. Based on these results, we conclude PLCG2 plays an important role in rat liver cell proliferation via ERK and NF-κB pathway by regulating the expression of and .
