Methods: Astrocytes were cultured from SD neonate rats. The expression and distribution of Cdk5 and p35 in cultured astrocytes were analyzed by immunofluorescence staining. Primary cultured astrocytes were subjected to oxygen-glucose deprivation/reperfusion(OGD/R),and the changes in Cdk5 and p35 expression after OGD/R were observed by Western blot. Results:Cdk5 and p35 were expressed in astrocytes,mainly in the cytoplasm and less in the nucleus,and both displayed similar cellular distribution.The expression of Cdk5 and p35 in astrocytes was increased during early phases and decreased during late phases after OGD/R. Conclusion: Both Cdk5 and p35 were expressed in astrocytes, and both showed similar, mainly cytoplasmic distribution. Cdk5 and p35 expression in astrocytes exhibited dynamic changes after OGD/R.

    • 摘要: Objective To study the influence of Cdk5 activity on the structure and function of glomerulus podocyte by transfection of p25 gene. Methods In 2014,differentiated and mature isolated mouse podocytes were cultured in RPMI 1640 medium with 10% fetal bovine serum and divided into three groups including control group,empty group and p25 group. p25 gene was cloned through the pAdTrack-CMV viral vector,and transfected into podocytes. After 48 hours,cells were collected for further analysis. Cdk5,p25,p35,Cleaved caspase3 expressions were detected by Western blotting method;Cdk5 activity were tested through immunoprecipitation and isotope γ-32 P marking methods. In order to observe the expression of Cdk5,p35 and structure of Actin in podocyte,immunofluorescent staining were conducted. Results Cak5 in HEK293 cells had positive expression while p35 had negative expression;there were different levels of Cdk5 and p35 in renal cortex,podocyte and glomerulus. p25 had negative expression in control group and empty group while positive expression in p25 group. As for the expression levels of Cleaved caspase3 and Cdk5 activity in different groups,differences were of statistical significance( P <0. 05);the expression levels of Cleaved caspase3 and Cdk5 activity in p25 group was higher than those in the other two groups (P < 0. 05). In p25 group,Actin within podocyte were arranged in disorder and forms of cells were abnormal,while those conditions were on the contrary in the other two groups. Conclusion p25 causes overactivation of Cdk5 and induces podocyte morphological change,Actin arrangement disorder and cell apoptosis. Therefore,Cdk5 activity plays an important role in maintaining normal structure and function of podocyte.%目的:通过在肾小球足细胞中转染 p25基因,探讨周期素依赖性蛋白激酶5(Cdk5)的活性对足细胞结构及功能的影响。方法2014年度,于含10%胎牛血清的 RPMI 1640培养液中培养分化成熟的小鼠离体足细胞,将足细胞分为对照组、空转染组和 p25转染组。应用 pAdTrack-CMV 病毒载体克隆 p25基因,并转染足细胞,48 h 收集细胞;采用 Western blotting 法测定 Cdk5、p25、p35及细胞凋亡相关蛋白 Cleaved caspase3的表达水平;应用免疫沉淀和同位素γ-32 P 标记法测定 Cdk5活性;足细胞免疫荧光化学染色,观察 Cdk5、p35在足细胞中的表达,以及足细胞 Actin的排列情况。结果 HEK293细胞 Cdk5表达阳性,p35表达阴性,肾脏皮质、足细胞和肾小球中均有不同程度的 Cdk5和 p35的表达。对照组和空转染组 p25表达阴性,p25转染组 p25表达阳性。各组细胞凋亡相关蛋白 Cleaved caspase3表达水平和 Cdk5活性比较,差异有统计学意义(P <0.05);其中 p25转染组细胞凋亡相关蛋白 Cleaved caspase3表达水平和 Cdk5活性高于对照组和空转染组(P <0.05)。p25转染组足细胞内 Actin 排列紊乱,细胞形态发生异常改变,对照组和空转染组细胞内 Actin 排列正常,细胞形态没有发生改变。结论 p25引起 Cdk5过度活性可致肾小球足细胞形态改变,Actin 排列紊乱,诱发细胞凋亡。因此,Cdk5的活性在维持足细胞正常结构和功能方面发挥重要作用。

Methods Fifty adult male SD rats were randomly divided into 0 h, 6 h, 12 h, 24 h, 3 d, 5 d, 7 d, 10 d after focal cerebral contusion, control and sham-operated groups (5 rats each group). The focal cerebral contusion rat model was established. The expression of p35 and p25 protein of the damage peripheral zone in brain were detected by HEstain-ing, immunohistochemistry and western blotting at different injury time. Results Alarge number of p35 protein and a small amount of p25 protein were expressed in control group and sham-operated group. After focal cerebral contusion, p35 presented unimodal change with time and p25 presented bimodal changes with time. Conclusion Expression of p35 and p25 showed different regularity with good time correlation, which could help to estimate the brain injury time.

    • 摘要: OpIAP (Orgyia pseudotsugata inhibitor of apoptosis protein) gene encodes an inhibitor of apoptosis protein (IAP) which comes fromOrgyia pseudotsugatamulticapsid polyhedrosis virus.p35geneisolated from anAutographa californicanu-cleo-polyhedron virus encodes a 35 kDa apoptosis protein inhibitor. The expression of both genes displays enhanced resistance in tobacco, maize and cotton. In this study, the full-length coding sequences ofOpIAPand p35 genes were synthesized, respectively. The transformation vector pUbi:p35-RSS1P:Myc-OpIAP containing two gene expression cassettes was constructed. In the expres-sion vector pUbi:p35-RSS1P:Myc-OpIAP, theOpIAP gene was driven by the rice sucrose synthase-1 promoter and thep35 gene was driven by the maizeubiquitin promoter. Embryo calli of Yangmai 16 were bombarded by the gold particle containing pUbi:p35-RSS1P:Myc-OpIAP vector DNA. Transgenic wheat plants in T0–T2 generations were subjected to PCR, RT-PCR, qRT-PCR, and Western blot analyses. The results indicated that the introducedOpIAPand p35genescould beinherited and ex-pressed in four transgenic wheat lines.Rhizoctonia cerealisisolate R0301 or WK207 was used to inoculate T1 andT2 plants for sharp eyespot severity assessments. The results showed that the transgenic wheat plants expressingOpIAPand p35 displayed sig-nificantly enhanced resistance to sharp eyespotcompared with non-transgenic wheat Yangmai 16. Thus, the introducedOpIAPand p35genes could be used in improving wheat resistance to wheat sharp eyespot caused by differentRhizoctonia cerealisisolates.%OpIAP (Orgyia pseudotsugata inhibitor of apoptosis protein)是黄杉毒蛾核型多角体病毒中编码细胞凋亡抑制蛋白(inhibitor of apoptosis protein, IAP)的基因,p35基因编码苜蓿斜纹夜蛾核型多角体病毒中具细胞凋亡抑制作用的35 kDa蛋白。本研究人工合成了OpIAP和p35基因,构建了同时含有OpIAP和p35表达盒的转双价基因载体pUbi:p35-RSS1P:Myc-OpIAP,两基因分别由玉米泛素基因启动子(Ubiquitin, Ubi)和水稻蔗糖合酶-1启动子(sucrose synthase-1 promoter,RSS1P)驱动。通过基因枪介导法将该载体导入小麦品种扬麦16,获得双价转基因小麦。对T0~T2代植株,利用PCR、RT-PCR、qRT-PCR及Western blot分析,确认导入的外源OpIAP和p35基因能够在4个转双价基因小麦株系中遗传并表达。用来源不同、致病力不同的禾谷丝核菌强致病株型 R0301和 WK207对转双价基因小麦的T1、T2代植株分别进行纹枯病抗性鉴定,结果表明,与受体扬麦16相比,双价转基因小麦的T1、T2代植株对纹枯病的抗性明显提高,说明OpIAP和p35基因的表达可以增强转基因小麦对来源不同、致病力不同的禾谷丝核菌的抗性。
