Abstract:
Objective To investigate the correlation between the expression of phospholipase Cβ1 (PLCβ1) and the clinical relevant parameters and prognosis in patients with hepatocellular carcinoma (HCC).Methods By using tissue microarray technique and immunohistochemical method,the expressions of PLCβ1 in tumor and pericancerous tissues were tested in 141 HCC patients.The relationship between the expressions of PLCβ1 and the clinical and pathological characteristics was analyzed.Colony formation assay and apoptosis experiments were used to check the effect of PLCβ1 on proliferation of HCC cells.KaplanMeier analysis and Cox multivariate regression model analysis were adopted to analyze the prognosis of HCC patients.Results The expression level of PLCβ1 in tumor tissues was obviously higher than that in pericancerous tissues,which was closely related to the tumor staging.Kaplan-Meier survival analysis indicated that the survival rate in HCC patients with high expression level of PLCβ1 was lower than that in HCC patients with low expression level of PLCβ1.Cox multivariate regression analysis revealed that high expression of PLCβ1 was an independent prognostic factor for HCC patients.Over expression of PLCβ1 in HCC cells could promote the proliferation of HCC cell and inhibit its apoptosis.Further investigation showed that activation of extracellular regulated protein kinase signaling pathway might be involved in PLCβ1-mediated HCC cell growth.Conclusion PLCβ1 can promote the progression of HCC,and the expression level of PLCβ1 can be regarded as an independent prognostic factor for HCC,and it is expected that PLCβ1 may become an ideal therapeutic target.
