克隆了‘津田芜菁’(Brassica rapa subsp. rapifera‘Tsuda’)通用调节因子14-3-3基因cDNA序列,命名为Br14-3-3(GenBank登录号为MK896872)。该基因全长1 113 bp,开放阅读框全长774 bp,编码含有257个氨基酸的多肽。荧光定量PCR分析Br14-3-3在‘津田芜菁’不同组织中及其在温度、脱水、渗透、ABA和无机盐等非生物胁迫下幼苗中的表达,结果表明该基因在‘津田芜菁’的花中表达量最高,幼苗中次之;低温抑制了Br14-3-3的表达,其他非生物胁迫可诱导该基因表达,暗示Br14-3-3在非生物胁迫应答中发挥功能。 相似文献

以龙眼(Dimocarpus longan Lour. ) 为试材, 应用同源克隆和RACE方法从花芽中获得了调控
蛋白14-3-3的全长cDNA序列, GenBank登录号为FJ479618 (GI: 218202931) 。该cDNA全长1 121 bp, 包括一个783 bp的开放阅读框, 编码261个氨基酸, 序列比较分析显示14-3-3 cDNA具有较高的保守性。半定量RT-PCR分析结果表明, 14-3-3 mRNA在龙眼叶芽、叶片、花芽和成熟的花中都有表达, 但在花芽中表达量最大。构建了pET14-3-3原核表达系统, 将14-3-3全长cDNA在大肠杆菌中表达, 获得一个分子量约为34 kD的可溶性融合蛋白, 经Western blotting验证, 该蛋白为14-3-3蛋白。 相似文献

AIM: The present study was designed to investigate the effect of adenovirus-mediated 14-3-3σ on the proliferation of Rat1-Akt cells and to explore whether this effect is completed regulating p27.METHODS: The effect of Ad-14-3-3σ gene transfection on Rat1-Akt cell proliferation was observed by using 5-bromodeoxyuridine (BrdU).Then immunofluorescence and kinase assay were used to detect the effect of Ad-14-3-3σ on the phosphorylated level and intracellular location of p27.RESULTS: Ad-14-3-3σ-infected cells had fewer BrdU-positive cells (45%) than control (which was set at 100%).However,Ad-β-gal-infected cells had a high percentage of BrdU-positive cells (98%).14-3-3σ gene transfection downregulated phosphorylation level of p27 and decreased Akt-mediated intracellular location of p27.CONCLUSION: Transfection of 14-3-3σ gene suppresses the proliferation of Akt overexpession cell line Rat1-Akt.14-3-3σ decreases phosphorylation of p27 by downregulating Akt kinase,blocks Akt-mediated cytoplasm dislocation of p27,and inhibits proliferation of Rat1-Akt cells. 相似文献

AIM:The present study was designed to investigate the effect of adenovirus-mediated 14-3-3σ on Rat1-Akt cell xenografts and to explore whether the effect was mediated through negative regulation of Akt. METHODS:The effect of Ad-14-3-3σ on Rat1-Akt cells xenografts was observed in nude mice ex vivo and in vivo. Western blotting was used to detect 14-3-3σ protein,phospho-Akt (Thr 308), phospho-Akt (Ser 473), and phospho-(Ser/Thr) Akt substrate in tumor tissue after transfection of 14-3-3σ gene. RESULTS:The tumor volume was dramatically decreased and its emergence was delayed, regardless of using Ad-14-3-3σ-treated Rat1-Akt cells (ex vivo) or injected Ad-14-3-3σ in vivo, of which the effect of the continuously injected group was the best. Levels of Akt protein, phosphorylated Akt and phosphorylated Akt substrates in tumors obtained from Ad-14-3-3σ-treated mice were markedly less than those in PBS or Ad-β-gal-treated mice. CONCLUSION:14-3-3σ suppressed Akt overexpession in cells of Rat1-Akt xenografts by negatively regulating Akt. 相似文献
