PICK1对人肝癌细胞HepG2增殖的影响
Function of PICK1 on proliferation of human HepG2 cells
摘要
Abstract
Objective To investigate the probably value of PICK1 in HCC patients after hepatectomy and to deter-mine the effects of PICK1 on the proliferation of human hepatocellular carcinoma cell lines HepG2 . Methods The differential expression of PICK1 in paired tumor and non-tumorous tissue was evaluated by RT-PCR, Western blot and immunohistochemistry. Exposure HepG2 cells with different concentrations of FSC-231(a small molecule inhib-itor of the PICK1 PDZ Domain). MTT assay was used to evaluate the inhibitory rate of proliferation of HepG2. Af-ter 24 h treatment of FSC-231 in HepG2 cells, the modulation of FSC-231 on cell cycle distribution of HepG2 cells was detected by flow cytometer, the CyclinD1, C-myc, Notch1, Hes-1 expression of HepG2 cells were examined by RT-PCR and Western blot. Results Compared with paired non-tumorous tissues, PICK1 were highly expressed in HCC tissue, significantly increased mRNA and protein level of PICK1 was observed in HCC tissue(P<0. 05);FSC-231 was able to effectively inhibit cell proliferation in a concentration and time dependent pattern and signifi-cantly decreased the protein levels of CyclinD1,C-myc and Notch1, Hes-1(P<0. 05). Conclusion PICK1 may be a potential therapeutic target gene for human hepatocellular carcinoma, probably correlating with Notch signal pathway.关键词
