METHODS： Sixty clean-grade Sprague-Dawley rats were divided randomly into six groups： normal control （NC）, asthma model, Guilong Kechuanning （GK） group, as well as high, intermediate-, and lowdose XP groups. Rats were sensitized with ovalbu- min （OVA） to trigger asthma. Serum concentrations of ECP, TNF-a and IL-4, eosinophil counts, as well as expression of MMP-9 and TIMP-1 in lung tissues were evaluated using an immunofluorescence method, mRNA expression of MMP-9 and TIMP-1 was determined using real-time quantitative poly- merase chain reaction. RESULTS： Compared with the asthma-model group, serum concentrations of ECP, TNF-a, and IL-4, and eosinophil counts decreased significantly in the high- and intermediate-dose XP groups and GK group （all P 〈 0.01）. Protein expression of MMP-9 and TIMP-1 decreased significantly in the high- and intermediate-dose XP groups and GK group （all P 〈 0.01）. Transcription of MMP-9 and TIMP-1 mRNA and the ratio of expression of MMP-9：TIMP-1 in lung tissue were significantly lower （P 〈 0.01）. CONCLUSION： XP can reduce TNF-a secretion, sup- press the infiltration/activation of eosinophils, re- duce serum concentrations of ECP and IL-4, reduce the protein and mRNA expression of MMP-9 and TIMP-1 in lung tissue, and regulate the balance between expression of MMP-9 and TIMP-1. In these ways, XP alleviated the inflammation and remodel- ing of the airways.展开更多

文摘目的:构建人血管抑素K1-3的重组酵母胞内表达质粒PH IL-D2/K1-3,获得重组目的蛋白。方法:从胎儿肝脏组织用RT-PCR方法扩增人血管抑素K1-3目的基因,克隆至酵母胞内表达质粒PH IL-D2中,线性化后转化到毕赤酵母GS115胞内,经PCR和Sourthern杂交筛选出阳性转化子,并用甲醇诱导表达。表达产物进行SDS-PAGE(12%)和W estern b lot检测,经赖氨酸亲和层析柱纯化后,用Lowry法测定蛋白含量,并进行生物活性测定。结果:SDS-PAGE和W estern b lot结果显示,表达蛋白质的相对分子量为30kd左右,低糖基化。Lowry法测定蛋白表达量为6.8mg/L。活性测定实验表明重组血管抑素能特异抑制人血管内皮细胞的增殖。结论:在毕赤酵母GS115胞内成功表达了人血管抑素K1-3重组蛋白。
