Insights into the Role of Oxidative Stress in Hepatocellular Carcinoma Development

Abstract

Oxidative stress (OS) is linked to hepatocellular carcinoma (HCC) progression. HCC may develop as a result of genetic changes, including oxidative injury to both nuclear and mitochondrial DNA. Signaling pathways regulated by OS, such as Wnt/β-catenin and Notch pathways, are vital regulators in developing HCC. OS-mediated activation of transcription factors, including nuclear factor-κB and p53, among others, is capable of regulating the redox state of HCC cells. OS also affects the tumor microenvironment, which, in turn, regulates HCC progression. In HCC, reactive oxygen species (ROS) can potentially enhance tumor cell proliferation, metastasis, and resistance to treatment. However, elevated ROS levels can cause cytotoxicity and trigger apoptosis in HCC cells. This review highlights and explores potential oxidative stress-related treatment targets in HCC, offering novel insights for clinical therapies.
