Abstract

Epigenetic alterations play an important aspect in the pathogenesis of oral cancer, affecting gene regulation occurs without altering the DNA sequence itself. These alterations include processes like DNA methylation, histone modification, and the regulation mediated by non-coding RNAs (ncRNAs), contribute to the initiation, progression, and metastasis of oral squamous cell carcinoma (OSCC). This review comprehensively examines the major epigenetic mechanisms implicated in oral cancer, elucidates potential biomarkers for early detection and prognosis, and explores emerging epigenetic therapies with significant potential for targeted treatment. The reversible characteristics of epigenetic modifications render them promising therapeutic targets and offers hope for improved clinical outcomes. We also discuss the current limitations in research and suggest future directions for developing effective epigenetic-based diagnostic and therapeutic strategies.
