[目的]探究Runt相关转录因子1(RUNX1)对金黄色葡萄球菌(Staphylococcus aureus,***)诱导的奶牛乳腺上皮细胞(MAC-T)发生上皮细胞间质转化(EMT)的作用及机制。[方法]通过CCK-8法检测不同感染复数的热灭活金黄色葡萄球菌处理后对MAC-T细胞活力的影响;通过倒置显微镜观察经金黄色葡萄球菌处理后MAC-T细胞的形态变化。通过实时荧光定量PCR和Western blotting技术检测金黄色葡萄球菌处理MAC-T细胞后,细胞中EMT标志分子(E钙黏蛋白(E-cadherin)、N钙黏蛋白(N-cadherin)、α平滑肌动蛋白(α-SMA)、波形蛋白(Vimentin))、TGF/Smad通路信号分子(TGF-β1、Smad2、Smad3、Smad4)和RUNX1的表达量变化情况;并比较了分别使用RUNX1和TGF-β特异性抑制剂前后细胞EMT标志分子、TGF/Smad通路信号分子和RUNX1的表达水平变化。[结果]不同浓度热灭活金黄色葡萄球菌处理72 h后,MAC-T细胞活力较24和48 h组均极显著下降(P<0.01),通过显微镜观察发现此时细胞出现漂浮死亡现象。因此后续观察细胞形态变化时设置时间为12、24、36和48 h。当用感染复数(MOI)为100热灭活金黄色葡萄球菌处理MAC-T细胞48 h后,细胞形态由上皮细胞典型的“鹅卵石”样转变为间质细胞的“长梭状”;实时荧光定量PCR和Western blotting检测结果发现,与正常细胞相比,EMT标志分子E-cadherin mRNA表达量极显著下调(P<0.01),Vimentin、α-SMA、N-cadherin、TGF-β1、Smad2、Smad3、Smad4和RUNX1 mRNA表达量显著或极显著上调(P<0.01);且Vimentin、α-SMA、P-Smad2和RUNX1蛋白表达量明显上调。经LY2109761抑制剂处理后,与感染组相比,2个抑制剂组MAC-T细胞中Smad2、Smad3、Smad4、N-cadherin、Vimentin、α-SMA和RUNX1的mRNA表达量均极显著下调(P<0.01),E-cadherin mRNA表达量极显著上调(P<0.01);经抑制剂Ro5-3335处理后,MAC-T细胞形态未出现显著的间质细胞样变化;与感染组相比,2个抑制剂Ro5-3335组细胞中E-cadherin的mRNA表达量极显著上调(P<0.01),N-cadherin、Vimentin、α-SMA(除10μmol/L Ro5-3335抑制剂组α-SMA外)、TGF-β1、Smad2、Smad3和Smad4的mRNA表达水平均极显著降低(P<0.01)。[结论]热灭活金黄色葡萄球菌处理MAC-T细胞48 h可激活TGF/Smad通路诱导MAC-T细胞发生EMT变化;RUNX1可通过介导TGF/Smad通路调节金黄色葡萄球菌诱导的MAC-T细胞EMT过程。

Using two structurally related benzoates bearing different H-bond acceptors as co-ligands, three new azido-CuⅡ compounds, [Cu(L1)(N3)(H2O)]n (1), [Cu(L1)(N3)(MeOH)]n (2), and [CuL2HL2(N3)3(H2O)]n (3) (HL1 = 4-nitrobenzoic acid; HL2 = 2-phenyl-4-quinolinecarboxylic acid), have been synthesized and structurally characterized. 1 is a carboxylate/EO-azido bridged copper chain, forming 3D structure by H-bonds, and 2 has a similar chain structure as 1 but forming a 2D structure by H-bonds, while 3 is a 3D supramolecular network with ternary center H-bonds. Magnetic study indicates that domain ferromagnetic coupling interactions were found to exist in complexes 1 and 3.

本试验旨在研究玉米-杂粕型饲粮中添加不同水平的复合纤维素酶对蛋鸡生产性能、蛋品质、肝脏中糖代谢相关酶活性、内源消化酶活性以及肠道中葡萄糖转运载体基因表达的影响,并筛选出复合纤维素酶的适宜添加量。选取288只健康状况良好的53周龄海兰褐蛋鸡,随机分为4组,每组6个重复,每个重复12只鸡。对照组饲喂玉米-杂粕(豆粕-棉籽粕-菜籽粕)型饲粮,3个试验组在玉米-杂粕型饲粮中分别添加200、400、600 mg/kg复合纤维素酶(主要成分为纤维素酶、木聚糖酶、淀粉酶和蛋白酶)。预试期7 d,正试期84 d。结果显示:1)与对照组相比,400 mg/kg组产蛋率显著提高(P0.05)。3)与对照组相比,玉米-杂粕型饲粮中添加400或600 mg/kg复合纤维素酶可以显著提高蛋鸡肝脏中丙酮酸激酶活性(P<0.05)。4)与对照组相比,400 mg/kg组蛋鸡空肠中淀粉酶与胰蛋白酶活性显著提高(P<0.05)。5)与对照组相比,玉米-杂粕型饲粮中添加400或600 mg/kg复合纤维素酶均可以显著提高蛋鸡空肠中钠-葡萄糖协同转运蛋白-1(SGLT-1)mRNA相对表达量(P<0.05)。综上可知,在玉米-杂粕型饲粮中添加复合纤维素酶可以通过提高饲粮中营养物质的释放量而增强蛋鸡小肠消化酶活性及肝脏中糖代谢相关酶活性,还能提高空肠中SGLT-1 mRNA相对表达量,进而改善生产性能。在本试验条件下,蛋鸡玉米-杂粕型饲粮中复合纤维素酶的最适添加量为400 mg/kg。
