Abstract
Resveratrol (RSV) is used for the treatment of various diseases due to their anti-inflammatory and antioxidant activities. However, its beneficial aspects on viral hepatitis have been less investigated. This report reviews the impact of resveratrol on viral hepatitis and chronic viral hepatitis-related hepatocellular carcinoma (HCC). The systematic review was performed and reported according to the PRISMA 2020 statement. Several core databases, such as Cochrane Library, PubMed, Web of Science, EMBASE, and Scopus, were used for search on September 6, 2023. After extraction of the data, the desired information of the full text of the studies was recorded in Excel, and the outcomes and mechanisms were reviewed. RSV inhibits viral replication through anti-HCV NS3 helicase activity, maintains redox homeostasis via glutathione (GSH) synthesis, improves T and B cell activity, and suppresses miR-155 expression. It also enhances viral replication by enhancing hepatitis C virus (HCV) RNA transcription, activating sirtuin-1 (SIRT1), which can increase peroxisome proliferator-activated receptor (PPAR), and SIRT1 activates the HBV X protein (HBx). Moreover, RSV is responsible for hepatitis-related HCC proliferation via suppression of mammalian target of rapamycin (mTOR), SIRT1 up-regulation, inhibiting expression of HBx, and reducing expression of cyclin D1. Despite the promising properties of RSV in inhibiting hepatitis-related HCC cell proliferation, its antiviral effects in viral hepatitis are controversial. The antihepatitis behaviors of RSV are mainly dose-dependent, and in some studies, activating some hepatoprotective pathways increases the transcription and replication of chronic HBV and HCV. Therefore, healthcare providers should be aware of viral hepatitis before using RSV supplements.
