DNA methylation and demethylation function in the balance between cellular differentiation and cancer. Although the roles of DNA methyltransferases have been extensively explored in epidermal biology, ten-eleven translocation (TET) demethylase enzymes are poorly understood. In their new article in the Journal of Investigative Dermatology, Boudra et al. present evidence for a tumor-suppressive role of TET2 and its regulation of 5-hydroxymethylcytosine in the prevention of squamous cell carcinomas.
DNA 甲基化和去甲基化在细胞分化和癌症之间的平衡中发挥作用。尽管 DNA 甲基转移酶的作用在表皮生物学中得到了广泛的研究,但 ten-eleven translocation(TET)去甲基化酶的作用却知之甚少。在他们发表在《皮肤病学研究杂志》上的新文章中,Boudra 等人提出 TET2 具有肿瘤抑制作用,其通过调节 5-羟甲基胞嘧啶来预防鳞状细胞癌。
