ABSTRACT
OBJECTIVE:
MicroRNAs (miR) participate in cell proliferation, apoptosis and transformation, as they can regulate gene expression and intracellular signal transduction for various physiological processes. MiR-122 and miR-22 are known to be related with occurrence and progression of hepatitis B virus (HBV)-related hepatocellular cancer (HCC). This study recruited HBV-related HCC patients, whose expression levels of miR-122 and miR-22 were determined to analyze the correlation with clinical and pathological indexes. PATIENTS ANDMETHODS:
HBV-related HCC patients were enrolled, in parallel with patients suffering from benign liver disease and non-HBV-related HCC. Real-time PCR was employed to measure miR-122 and miR-22 expression levels.RESULTS:
The relative expression levels of miR-122 and miR-22 in HBV-related HCC patients were 1.26 ± 2.73 and 5.49 ± 3.91, respectively, which were significantly lower than that in benign liver disease or non-HBV-related HCC patients (p < 0.05). No significant difference of serum miR-122 or miR-22 levels was found between benign liver disease and non-HBV-related HCC patients (p > 0.05). The miR-122 and miR-22 levels were negatively correlated with tumor size, lymph node metastasis, TNM stage, pathological type, differentiation grade, liver cirrhosis, AFP and HBV DNA, all of which were independent risk factors (p < 0.05).CONCLUSIONS:
MiR-122 and miR-22 were downregulated in HBV-related HCC patients, and were related with tumor size, lymph node metastasis, TNM stage, pathological type, differentiation grade, liver cirrhosis, AFP and HBV DNA.
