Effects of 5-Azacitidine on Dnmt2/Trdmt1 expression levels and endoplasmic reticulum stress in cellular models of insulinoma

Diabetes mellitus affects people all over the world of all ages or social groups making it a worldwide healthcare challenge. Moreover, untreated or badly treated diabetes carries a risk of serious complications including premature death (IDF Diabetes Atlas 9th edition, 2019). The main symptom of diabetes is insulin secretion and/or action disorder leading to hyperglycemia what results in impaired carbohydrate, fat, and protein metabolism (“Diagnosis and Classification of Diabetes Mellitus,” 2013). Dnmt2/ Trdmt1 in its structure and sequence is similar to DNA methyltransferases, however, it has been shown that mainly methylates aspartic acid transfer RNA, specifically at the cytosine-38 resi…
