Abstract:

Objective

To study the expression of HBx protein (Hepatitis B virus X antigen,HBx)and miR-143 in the serum of patients with hepatitis B related liver disease, and to explore the relationship between HBx protein and miR-143, and their roles in hepatitis B related liver cancer.

Methods

169 serum samples were collected from patients with HBV-related liver disease in the Laboratory Department of the Second Affiliated Hospital of Guangzhou Medical University. According to the course of hepatitis B disease, they were divided into chronic hepatitis B group (78 cases), HBV-related liver cirrhosis group (53 cases) and HBV-related liver cancer group (38 cases). Serum samples from 20 healthy people were selected as the control group. Serum HBx protein and hepatitis B were detected by ELISA; Serum miR-143 and HBV DNA were detected by Quantitative Real-time PCR(qPCR); AFP was detected by automatic chemiluminescence immunoassay (CLIA).

Results

The expression levels of miR-143 and AFP in HBx positive group were significantly higher than those in HBx negative group (P<0.05); The positive rate of HBx and the expression of miR-143 in the high level group of hepatitis B virus replication were significantly higher than those in the other three groups (P<0.05); The positive rate of HBx in liver cirrhosis group and liver cancer group was significantly higher than that in chronic hepatitis B group. The expression of serum miR-143 and AFP in liver cancer patients was significantly higher than that in the other three groups (P<0.05); The relative expression of miR-143 in HBx positive group was significantly higher than that in HBx negative group (P<0.05).

Conclusions

serum HBx is closely related to the expression of miR-143 in a dose-dependent manner. miR-143 may be involved in the progression of hepatitis B virus X protein mediated hepatitis B liver cancer. Both of them play an important role in the development of chronic hepatitis B into liver cancer, which provides a new direction for the diagnosis and treatment of hepatitis B liver cancer.

Key words: HBx protein, miR-143, Hepatitis B related liver cancer
