Fonction de l'ARNnc exosomal HEIH dans le carcinome h épatocellulaire associé au virus de l'hépatite B

This study aimed to investigate the expression of exosomal lncRNA-HEIH in B-HCC patients and explore its clinical significance. We collected blood samples from 60 B-HCC patients, 60 non-hepatitis virus-associated HCC (N-HCC) patients, and 50 healthy volunteers. Exosomal lncRNA-HEIH levels were measured by real-time PCR and analyzed for their correlation with patient prognosis using Kaplan-Meier analysis. Multivariate COX regression analysis was conducted to identify factors affecting patient outcomes. The effects of lncRNA-HEIH on carcinogenesis were also investigated by constructing a Huh7 cell line stably expressing the hepatitis B virus. In the B-HCC group, there was a positive correlation between hepatitis B virus and exosomal lncRNA-HEIH. The 5-year survival rate of the exosomal lncRNA-HEIH high-expression group was significantly lower than that of the low-expression group in the B-HCC group, but not in the N-HCC group. Exosomal lncRNA-HEIH level was related to the TNM stage, lymph node metastasis and AFP. Exosomal lncRNA-HEIH level was independent risk factors for poor prognosis in B-HCC patients. In Huh7-HBV cells, lncRNA-HEIH level was significantly higher than in control, and the migration capacity of Huh7-HBV cells decreased significantly after down-regulating lncRNA-HEIH. Our findings suggest that exosomal lncRNA-HEIH is abnormally expressed and closely related to poor prognosis in B-HCC patients, indicating its potential as a diagnostic and therapeutic target for ...
