This research also studied the relationship between serum concentration of TGFβ1 and childhood asthma. Method: From June 2022 to December 2023, 121 children had physical examination in affiliated Hospital of Youjiang Medical University for Nationalities were selected as control group and 118 children suffered from asthma in affiliated Hospital of Youjiang Medical University for Nationalities during the same period were selected as asthma group. Result: There was no correlation between rs1800469, rs1800470, rs2241712, rs2241715, rs4803455 and asthma in Baise, Guangxi children. Linkage disequilibrium analysis showed that there were strong linkage disequilibrium among rs1800469, rs1800470, rs2241712, rs2241715 and rs4803455. Their haplotypes had no significant correlation with childhood asthma. The serum concentration of TGFβ1 in asthma group was lower than that in control group (p β1 had no significant relationship with the genotypes of rs1800469, rs1800470, rs2241712, rs2241715 and rs4803455.展开更多
为研究TGF-β通路对猪颗粒细胞增殖、凋亡的影响,本研究对TGF-β通路基因进行调控处理,设计并筛选可高效干扰TGFβRⅠ及TGFβRⅡ表达的载体,转染不同干扰载体及添加10 ng/m L TGFβ1和25 ng/m L FSH,采用Westernblot、MTT和流式细胞法...为研究TGF-β通路对猪颗粒细胞增殖、凋亡的影响,本研究对TGF-β通路基因进行调控处理,设计并筛选可高效干扰TGFβRⅠ及TGFβRⅡ表达的载体,转染不同干扰载体及添加10 ng/m L TGFβ1和25 ng/m L FSH,采用Westernblot、MTT和流式细胞法检测不同处理对颗粒细胞TGFβ RI和TGFβ RII蛋白表达量和细胞增殖凋亡的影响。结果表明:成功筛选出干扰效率最高的p OSP1-TGFβRⅠ-sh5和p OSP1-TGFβRⅡ-sh3载体,对TGFβRⅠ和TGFβRⅡ的抑制率分别为78.00%和84.10%;转染后TGFβRⅠ干扰组的TGFβRⅠ蛋白表达量显著低于其阴性对照组;TGFβRⅡ干扰组、TGFβ1组和FSH组的TGFβRⅡ蛋白表达量显著低于其阴性对照组;TGFβ RI干扰组、TGFβ RII干扰组的增殖抑制率极显著高于PLL3.7空载体组,TGFβ 1组细胞增殖抑制率极显著高于空白对照组且FSH组的增殖抑制率显著高于空白对照组;TGFβRⅠ干扰组和TGFβRⅡ干扰组细胞凋亡率极显著高于PLL3.7空载体组;TGFβ1组和FSH组细胞凋亡率极显著高于空白对照组。总之,RNAi介导的TGFβRⅠ和TGFβRⅡ沉默和外源因子(10 ng/m L TGFβ1和25 ng/m L FSH)引起的TGFβRⅡ蛋白下调,均会减弱TGF-β信号传导通路对卵泡颗粒细胞的促进作用,进而抑制卵泡颗粒细胞的增殖,促进其凋亡。展开更多
