Abstract

Unlike genetic changes, epigenetics modulates gene expression without stable modification of the genome. Even though all cells, including sperm and egg, have an epigenome pattern, most of these modifications occur during lifetime and interestingly, some of them, are reversible. Lifestyle and especially nutrients as well as diet regimens are presently gaining importance due to their ability to affect the epigenome. On the other hand, since the epigenome profoundly affects gene expression profile it can be speculated that the epigenome could modulate individual response to nutrients. Recent years have thus seen growing interest on nutrients, macronutrients ratio and diet regimens capable to affect the epigenetic pattern. In fact, while genetic alterations are mostly detrimental at the individual level, reshaping the epigenome may be a feasible strategy to positively counteract the detrimental effect of aging. Here, I review nutrient consumption and diet regimens as a possible strategy to counteract aging-driven epigenome derangement.

摘要

与遗传变化不同,表观遗传学调节基因表达而不改变基因组的稳定修饰。尽管所有细胞,包括精子和卵子,都有一个表观基因组模式,但这些修饰大多发生在一生中,有趣的是,其中一些是可逆的。生活方式,特别是营养物质和饮食方案,由于它们能够影响表观基因组,目前正变得越来越重要。另一方面,由于表观基因组深刻地影响基因表达谱,可以推测表观基因组可以调节个体对营养物质的反应。因此,近年来人们对能够影响表观遗传模式的营养物质、宏量营养素比例和饮食方案越来越感兴趣。事实上,虽然遗传改变在个体水平上大多是有害的,但重塑表观基因组可能是一种可行的策略,可以积极抵消衰老带来的有害影响。在这里,我回顾了营养物质的消耗和饮食方案作为一种对抗衰老驱动的表观基因组失调的可能策略。
