| 1 | Chaga mushroom (Inonotus obliquus) induces G0/G1 arrest and apoptosis in human hepatoma HepG2 cells显示文摘AIM: To investigate the anti-proliferative and apoptotic effects of Chaga mushroom (Inonotus obliquus) water extract on human hepatoma cell lines,HepG2 and Hep3B cells. METHODS: The cytotoxicity of Chaga extract was screened by 3-4,5-dimethylthiazol-2-yl-2,5-diphenyltetrazolium bromide (MTT) assay. Morphological observation,flow cytometry analysis,Western blot were employed to elucidate the cytotoxic mechanism of Chaga extract. RESULTS: HepG2 cells were more sensitive to Chaga extract than Hep3B cells,as demonstrated by markedly reduced cell viability. Chaga extract inhibited the cell growth in a dose-dependent manner,which was accompanied with G0/G1-phase arrest and apoptotic cell death. In addition,G0/G1 arrest in the cell cycle was closely associated with down-regulation of p53,pRb,p27,cyclins D1,D2,E,cyclin-dependent kinase (Cdk) 2,Cdk4,and Cdk6 expression. CONCLUSION: Chaga mushroom may provide a new therapeutic option,as a potential anticancer agent,in the treatment of hepatoma. | Myung-Ja Youn Jin-Kyung Kim Seong-Yeol Park Yunha Kim Se-Jin Kim Jin Seok Lee Kyu Yun Chai Hye-Jung Kim Ming-Xun Cui Hong Seob So Ki-Young Kim Raekil Park | 2008 | World Journal of Gastroenterology2008，14，4： | 13 |
| 2 | Cisplatin ototoxicity involves cytokines and STAT6 signaling network显示文摘我们此处调查了在支持 inflammatory cytokines 和 cisplatin ototoxicity 的生产表明串联的 STAT 的角色。cisplatin 注射引起的一个重要听觉缺陷在 Balb/c 被观察(野类型, WT ) 并且 STAT4 −/−, 然而并非在 STAT6 −/− 老鼠。而且,蛋白质的表示层次和支持 inflammatory cytokines 的 mRNA,包括 TNF-α, IL-1β,并且 IL-6,显著地在 WT 和 STAT4 −/−, 然而并非 STAT6 −/− 老鼠的浆液和蜗被增加。Organotypic 文化表明 stereocilia 捆的形状和在从 STAT6 −/− 鼠标的 Corti 的机关的感觉毛细胞层的数组在有 cisplatin 的处理以后是未经触动的,而那些高度在处理以后从 WT 和 STAT4 −/− 鼠标被弄歪并且弄乱。Cisplatin 在 HEI-OC1 听觉的房间导致了 STAT6 的 phosphorylation,并且由显著地保护的 STAT6 特定的 siRNA 的 STAT6 击倒从导致 cisplatin 的房间死亡的 HEI-OC1 听觉的房间和禁止的支持 inflammatory cytokine 生产。我们进一步证明 cisplatin 导致的 IL-4 和 IL-13 与 IL-4 受体 alpha 和 IL-13Rα 由绑定调制了 STAT6 的 phosphorylation; 1。这些调查结果建议发信号的 STAT6 在调停 cisplatin 的支持 inflammatory cytokine 生产和 ototoxicity 起一个枢轴的作用。 | Hyung-Jin Kim Gi-Su Oh Jeong-Han Lee Ah-Ra Lyu Hye-Min Ji Sang-Heon Lee Jeho Song Sung-Joo Park Yong-Ouk You Jeong-Dug Sul Channy Park Sang-Young Chung Sung-Kyun Moon David J Lim Hong-Seob So Raekil Park | 2011 | Cell Research2011，21，6： | 2 |
