The eyes were periodically examined by retinoscopy, and A-scan ultrasonography. Two weeks later, the eyeballs were removed and the apoptotic cells were determined by electron microscopy, TUNEL technique and flow cytometry in scleras. Both bFGF and the bcl-2 protein were determined by the immunohistochemisty method and the Western-blot method. Results: All eyes treated with -10.00D or -20.00D concave lens produced defocus-induced myopia.

Aberrant DNA methylation patterns go beyond the fields of epigenesis. Its mainly about a reaction of cytosine transformation into S-methylcytosine mediated by methyltransferases.

DNA甲基化是表遗传学上研究最深入的一种机制，是由甲基转移酶介导，将胞嘧啶变为S—甲基胞嘧啶的一种反应。

The types of histone methyltransferases, the relationship between methylation of Lysine 9 of H3 and the formation of heterochromatin, gene regulation in euchromatin, and that with DNA methylation, were mainly introduced.

主要阐述了组蛋白甲基转移酶的类型，组蛋白H3中第9位赖氨酸甲基化与异染色质的形成、常染色体中基因表达的调控，以及与DNA甲基化之间的关系，说明了组蛋白甲基化与组蛋白乙酰化、磷酸化的相互关系，指出组蛋白甲基化对维持细胞各种状态的平衡起到极其重要的作用。

Among these systems, the expression level of ZNF191(243—368) was increased in inclusion body system under a higher isopropylthio-β- D -galactoside concentration, but the non-target proteins were also increased more, which made its purification more difficult and the yield lower.

为了能够得到充足的锌指蛋白ZNF191(243-368)来研究其性质、结构和功能间的关系，本文研究了包涵体、谷胱甘肽 S－转移酶和组氨酸标签三个表达体系来表达ZNF191(243-368)。
