As reported by some researchers, most of them enters the ER and is esterified by an ER enzyme ACAT2,then incorporated with apo B48 to produce de novo chylomicron which goes into the lymph and then to the circulation.

据文献报道，进入肠细胞的胆固醇能在酰基辅酶A：胆固醇酰基转移酶2(Acyl-Coenzyme A Cholesterol Acyltransferase，ACAT2)的作用下形成胆固醇酯，并与apoB48组装形成乳糜微粒，经淋巴进入血液。

Part I Cbx4 promotes SUMO modification of DNA methyltransferase 3a Dnmt3a is one of de novo DNA methyltransferases in mammals, which are responsible for the generation of somatic methylation patterns during embryogenesis and gametogenesis.

第一部分：Cbx4促进DNA甲基转移酶3a的SUMO化修饰 Dnmt3a是哺乳动物中的一个起始性甲基转移酶，负责在胚胎发育和配子发生过程中创建各类细胞的甲基化谱式。

Female gametogenesis in higher plants undergoes various developmental changes, including the de novo formation of germline cells, the differentiation of the megaspore mother cell, meiosis, megaspore selection, and the development of the embryosac.

高等植物雌配子体的形成涉及孢原细胞和大孢子母细胞的确立与分化、大孢子发生、功能大孢子以及胚囊的形成和发育等多种复杂调控过程。随着当代生物技术及功能基因组学的发展，近年对雌配子体发育的研究已从细胞学描述逐渐过渡到对基因和发育调控分子机理的探索。
