Item Epigenetic Alterations in Hepatocellular Carcinoma: Mechanisms, Biomarkers, and Therapeutic Implications(Pharmaceuticals, 2025) Wali, Adil Farooq; Ansari, Abid Reza; Mir , Prince Ahad; El-Tanani , Mohamed; Babiker , Rasha; Hussain, Md Sadique; Uppal, Jasreen; Zargar, Asma Ishrat; Mir, Reyaz HassanHepatocellular carcinoma (HCC), the most prevalent primary liver cancer, continues to pose a significant global health burden due to its high mortality rate. In addition to genetic alterations, epigenetic aberrations, including DNA methylation, histone modifications, chromatin remodeling, and noncoding RNA (ncRNA) dysregulation, play critical roles in HCCinitiation and progression. Notably, miR-375 and miR-483-5p are among the most dysregulated miRNAs in HCC, with their altered expression levels closely associated with tumor stage and patient survival. These epigenetic modifications offer promising therapeu tic avenues due to their reversibility and dynamic nature. Furthermore, specific epigenetic signatures such as CDH1 promoter hypermethylation and HOTAIR overexpression are being explored as potential biomarkers for early detection and treatment response. In this chapter, we review recent advances in the epigenetic landscape of HCC and discuss their diagnostic and therapeutic implications, highlighting their potential to improve patient outcomes through personalized medicine approaches
