Methods:The luciferase reporter plasmids of MDM2 P2 promoter containing different SNP309 were contructed,and cotransfected into CV-1 cells with AML1-ETO,AML1 and SP1 expression plasmid.The transactivities of luciferase were assayed by luminometer to determine the impact of AML1,AML1-ETO,and SP1 on MDM2 P2 promoter.
研究方法:构建含不同SNP309位点的MDM2 P2启动子的报告质粒,与AML1-ETO、AML1以及SP1的表达质粒单独或共转染CV-1细胞,测定荧光素酶的活性,分析AML1-ETO、AML1以及SP1对MDM2 P2启动子的影响。

We demonstrate that both the IL-5 mRNA expression and IL-5 protein production were stimulated by TSA and NaBu treatments. Chromatin immunoprecipitation assays showed that treatments of TSA and NaBu caused hyperacetylation of histones H3 and H4 at the IL-5 gene promoter in Jurkat cells, which consequently promoted the exogenous luciferase activity driven by this promoter.
TSA和丁酸钠能促进IL-5基因的mRNA和蛋白的表达水平,并增强该基因启动子所介导的外源荧光素酶报告基因的活性,这一增强作用与两种抑制剂介导的IL-5基因启动子上组蛋白H3和H4的高乙酰化有关。

Results:One hundred and eleven eyes were treated with PRP, 95 eyes were treated with mild-PRP. Visual acuity was increased by 1~3 lines in 82 eyes(35%), not changed in 94 eyes(46%) and decreased in 30 eyes(19%). On Fundus fluorescein angiography 3 months later, new vessels shrinked and retinal edema recovered in most cases, but in 10 eyes, new vessels and small nonperfusional areas still could be seen after the treatment, which was treated again.
结果:111只眼行广泛视网膜光凝术治疗,95只眼行亚广泛视网膜光凝术治疗。82只眼视力提高1~3行,占35%;94只眼视力无变化,占46%;30只眼视力下降,占19%。3个月后行荧光素眼底血管造影检查,新生血管大部分萎缩,视网膜水肿消退,有10只眼残留新生血管及小片状无灌注区,再次补充光凝。
