维生素A和锌是两种极为重要且我国居民膳食相对容易缺乏的微量营养素。研究发现,维生素A严重缺乏可导致胚胎一系列畸形,其原因与发育基因表达水平有关。锌与体内数百种酶的结构和功能相关,有报道缺锌可致胚胎畸形,其机制是缺乏可影响染色质的结构和基因表达水平。HOX基因是目前研究最多的胚胎发育控制基因。为了进一步揭示维生素A、锌的营养水平和胚胎发育的关系,本文
Vitamin A and zinc are two extremely important micronutrients that are relatively deficient in our diet. The study found that a serious lack of vitamin A can lead to a series of embryonic deformities, the reason and developmental gene expression levels. Zinc is associated with the structure and function of hundreds of enzymes in the body. It has been reported that lack of zinc causes embryo malformations, and its mechanism is lack of structure and gene expression that can affect chromatin. HOX gene is currently the most studied embryonic development control gene. In order to further reveal the relationship between vitamin A, zinc nutrition and embryonic development, this article
