| 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 |
| 7 | Neuromodulation-Based Stem Cell Therapy in Brain Repair:Recent Advances and Future Perspectives显示文摘Stem cell transplantation holds a promising future for central nervous system repair. Current challenges, however, include spatially and temporally defined cell differentiation and maturation, plus the integration of transplanted neural cells into host circuits. Here we discuss the potential advantages of neuromodulation-based stem cell therapy, which can improve the viability and proliferation of stem cells, guide migration to the repair site,orchestrate the differentiation process, and promote the integration of neural circuitry for functional rehabilitation.All these advantages of neuromodulation make it one potentially valuable tool for further improving the efficiency of stem cell transplantation. | Ti-Fei Yuan Yi Dong Li Zhang Jieyu Qi Chun Yao Yongjun Wang Renjie Chai Yan Liu Kwok-Fai So | 2021 | Neuroscience Bulletin2021，37，5： | 0 |
