Epigenetics in Cancer Therapy

Abstract

Epigenetics regulates parts of the genetic information accessible to cellular machinery, thus contributing to cellular diversity. Disruption of epigenetic harmonisation can lead to dysregulation of signaling pathways and contribute to diseases like cancer. Epigenetic processes are crucial in coordinating the normal growth and preservation of gene activity unique to mammal tissues. Epigenetic studies in current cancer research are vital for early detection through biomarker identification, understanding tumor heterogeneity, predicting treatment responses, and uncovering resistance mechanisms. This knowledge informs targeted therapies, enhances personalized medicine, and improves overall outcomes in cancer patients. This review comprehensively explores epigenetic processes in healthy cells, emphasizing histone modification-lysine acetylation and DNA methylation. The intricate mechanisms governing genetic expression and their dysregulation in cancer progression are also reviewed. Examining prevalent cancer types, this review stresses the pivotal role of epigenetics in understanding and potentially targeting these processes for therapeutic interventions.
