我们最近证明,在早期发育期间暴露于次优饮食导致编码HNF-4α的基因的启动子-增强子相互作用的异常表观遗传调节,HNF-4α是胰腺β细胞分化和葡萄糖稳态所需的关键转录因子。此外,我们的研究表明,次优的母亲饮食放大了该位点与年龄相关的表观遗传沉默。在这个研究的角度来看,我们讨论了这些新的发现的背景下,越来越多的表观遗传机制,环境可以影响基因活性,并强调其影响的2型糖尿病的发展与年龄的机械基础的理解。
We have recently demonstrated that exposure to a suboptimal diet during early development leads to abnormal epigenetic regulation of a promoter-enhancer interaction at the gene encoding HNF-4α, a key transcription factor required for pancreatic β-cell differentiation and glucose homeostasis. In addition, our studies revealed that the suboptimal maternal diet amplifies the age-associated epigenetic silencing of this locus. In this research perspective we discuss these novel findings in the context of the growing list of epigenetic mechanisms by which the environment can affect gene activity and emphasize their implications for the understanding of the mechanistic basis of the development of type 2 diabetes with age.
