Epigenetic Mechanisms in Type-2 Diabetes Mellitus: A Narrative Review

The incidence of Type-2 Diabetes Mellitus (T2DM) has increased significantly in the last several decades, which is an important challenge for health professionals and researchers. The systems that mediate the interaction between environmental factors and the genes, such as epigenetics, may have a specific bearing on the aetiology of T2DM. With an emphasise on the part that epigenetics plays in the pathophysiology of T2DM, the present study attempts to give a thorough overview of the mechanisms behind disease initiation, possible biomarkers, and the consequences for T2DM. The findings suggest that (3-cell malfunction, insulin resistance, and other metabolic abnormalities connected to T2DM are related to epigenetic alterations, which include that impact the development and course of the disease, including nutrition, exercise and pollution exposure, also have an impact on these epigenetic modifications. Knowing the complex interactions among genetics, epigenetics and environment is essential to pinpointing the precise aetiology of T2DM and creating customised treatment regimens. Epigenetic biomarkers could be helpful for risk assessment, early diagnosis, and tailored therapy for people with T2DM who are at risk or who have already been diagnosed. Future research must concentrate on unravelling the mechanistic understanding of the epigenetic pathways of T2DM in order to enhance therapeutic treatment and delve deeper into the pathophysiology of the condition.
