Circular RNAs in hepatitis B virus-induced hepatocellular carcinoma: A comprehensive review and recent advances.

Circular RNAs (circRNAs) are a class of stable and versatile non-coding RNAs that are pivotal in the occurrence and development of some diseases, particularly tumors. Hepatitis B virus (HBV)-induced hepatocellular carcinoma (HCC) is a liver disease with substantial global impact. Despite efforts towards adequate management, the survival of patients with HBV-induced HCC has been consistently low. circRNAs regulate various physiological activities of HBV-induced HCC. This review aims to elucidate the biogenesis of circRNAs and the pathophysiology of HBV-induced HCC and comprehensively analyze the applications of circRNAs in oncology and therapeutics. In addition, this review summarizes past research achievements on circRNAs in HBV-induced HCC. Finally, the limitations of existing methodologies and circRNA research in HBV-induced HCC have been discussed to provide a blueprint for future investigations.
