Analysis of the correlation between the expression of PPP2R3A gene and prognosis in patients with HBV-related hepatocellular carcinoma
Objective To investigate the expression level of protein phosphatase 2A regulatory subunit B alpha(PPP2R3A)gene in patients with Hepatitis B virus(HBV)related hepatocellular carcinoma and its relationship with prognosis.Methods Utilizing the immunohistochemical method,we analyzed the expression levels of PPP2R3A protein in 82 samples of HBV-related hepatocellular carcinoma and 21 cases of benign liver disease.Additionally,the RT-PCR technique was applied to quantify the mRNA levels.Results Our findings revealed that the PPP2R3A protein expression in liver cancer tissue(95.12％)was substantially elevated compared to its levels in pericancerous tissue(43.9％),with statistical significance(P＜0.05).There was a notable correlation between the expression intensity of PPP2R3A protein and the AFP value of liver cancer patients,exhibiting statistical difference(P＜0.05).RT-PCR analysis indicated that the median mRNA expression level of PPP2R3A in HCC tissues was 0.183(0.008～0.667),which was significantly higher than that in adjacent tissues(0.098(0.004～0.583)(Z=6.839,P＜0.05).By analyzing the survival data of follow-up HCC patients,it was found that the median overall survival(OS)of patients in the PPP2R3A high expression group was 46.6 months,which was significantly different from that in the low expression group(82.9 months)(P＜0.05).The median survival of RFS in patients PPP2R3A the high-expression group was 18.3 months,which was lower than that in the low-expression group(42.6 months)(P＜0.05).The median survival of PFS in patients PPP2R3A the high-expression group was 15.9 months,which was lower than that in the low-expression group(34.4 months)(P＜0.05).The median survival of DSS in patients PPP2R3A the high-expression group was 70.5 months,which was lower than that in the low-expression group(84.7 months)(P＜0.05).Conclusion The high expression of PPP2R3A protein in HBV-related hepatocellular carcinomar tissue and serum is related to the clinicopathological characteristics of liver cancer,which may be related to the poor prognosis of liver cancer.
