| 1 | Inhibitory effect of apolipoprotein A-I on matrix metalloproteinase-2 expression in vivo and in vitro显示文摘在现在的学习,我们调查了 apolipoprotein A-I 的效果(apoA -- 我) 在矩阵 metalloproteinase-2 (MMP-2 ) 上在 vivo 并且在 vitro 的表示。首先,我们检测了 apoA 的效果 -- 我在主动脉 MMP-2 上,激活 proliferator 的受体 /(PPAR /) , cyclooxygenase-2 (COX-2 ) ,和在动脉粥样硬化患者兔子的原子因素 kappa B (NF-B ) 表情用 immunohistochemical 方法建模的 peroxisome。结果证明 MMP-2, COX-2,和 NF-B 的表情在与 apoA 对待的动脉粥样硬化患者兔子的主动脉被减少 -- 我,当 PPAR / 表示被增加时。然后,我们选择了重要发炎房间,在 vitro 证明那些效果的巨噬细胞。巨噬细胞被划分成六个组并且与 apoA 的不同集中对待 -- 我, MMP-2 的 mRNA 表情, PPAR / ,和 COX-2 然后用 PPAR 的反向抄写的聚合酶链反应,和蛋白质表示被决定, NF-B 被西方的污点分析检测。在有教养的上层清液的 MMP-2 和 PPAR 的层次用连接酶的 immunosorbent 试金被决定。有趣地,在里面 vitro 结果类似于结果在里面 vivo 学习。在有 apoA 的孵化以后 -- 我为 24 h, MMP-2 的表情, COX-2,和 NF-B 被减少,当 PPAR / 表示被增加时。在他们在在 vivo 并且在 vitro 做匾马厩的进程的特别角色的考虑,我们推测 apoA 的禁止的效果 -- 我可以与 apoA 的效果在 MMP-2 表示上有一种靠近的关系 -- 我在 PPAR / , COX-2,和 NF-B 表达式上。尽管进一步的研究被需要澄清这些效果的内在的机制,我们的调查结果提供新奇卓见进 apoA 的反动脉粥样硬化患者匾破裂效果 -- 我。 | Weina Wang Xunlong Shi Yuan Yuan Haiyan Zhu Wei Zhou Hai Huang Meiqing Feng | 2013 | Acta Biochimica et Biophysica Sinica2013，45，3： | 2 |
| 3 | Houttuynia cordata polysaccharides alleviate ulcerative colitis by restoring intestinal homeostasis显示文摘Houttuynia cordata is traditionally used as phytoantibiotics for treating lung disease in China.Houttuynia cordata polysaccharides(HCPs)have been reported to alleviate influenza virus-induced intestinal and lung immune injury by regulating the gutlung axis.The present study aims to investigate the effects and mechanisms of HCPs on ulcerative colitis(UC).Male C57BL/6 mice were induced by dextran sodium sulfate(DSS)to establish the UC animal model.Our results showed that HCPs significantly reduced the weight loss and the shortening of colon length in colitis mice,and relieved the pathological damage of colon mucosa and inhibited the expression of pro-inflammatory cytokines such as TNF-α,IL-1β,IL-6,etc.It was suggested that HCPs could significantly improve DSS-induced colitis in mice.HCPs directly protected intestinal epithelial cells,ameliorated epithelial barrier dysfunction and cell apoptosis,which was also proved in H2O2 stimulated cell apoptosis model.HCPs inhibited inflammation in the colon,which was related to suppressing the infiltration of macrophages,inhibiting the expression of pro-inflammatory cytokines and proteins(TLR4,NF-κB),and restoring the dysfunction of Th17 and Treg cells.HCPs also restored the alteration of intestinal flora induced by DSS,increased the abundance of Firmicutes and Bacteroides,and reduced the abundance of Proteobacteria.This study confirmed the protective effect of Houttuynia cordata polysaccharide extracted from traditional Chinese medicine on ulcerative colitis,of which the mechanism was closely related to the maintenance of intestinal homeostasis(intestinal barrier,immune cells,and intestinal bacteria). | CEN Lifeng YI Tong HAO Yuanzhen SHI Chenchen SHI Xunlong LU Yan CHEN Daofeng ZHU Haiyan | 2022 | Chinese Journal of Natural Medicines2022，20，12： | 1 |
