| 1 | Celastrus orbiculatus extract induces mitochondrial-mediated apoptosis in human hepatocellular carcinoma cells显示文摘OBJECTIVE:To investigate the apoptotic effects and underlying molecular mechanisms of Celastrus orbiculatus(C.orbiculatus) extract in human hepatocellular carcinoma cells.METHODS:Human hepatocellular carcinoma cells(HCCLM6) were treated with C.orbiculatus extract(COE) at different nontoxic concentrations(10,20,40,80,and 160 μg/mL).The effect of COE on HC-CLM6 viability was examined using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide(MTT) assays.Cellular apoptosis following COE treatment was assessed by flow cytometry and western blot analysis.RESULTS:COE significantly inhibited cell viability and induced apoptosis of HCCLM6 cells in a dose-dependent manner.Apoptosis was accompanied by increased Bax expression and decreased Bcl-2 expression.In addition,COE treatment led to the release of cytochrome c,activation of caspase-3,and cleavage of poly(ADP-ribose) polymerase(PARP).Furthermore,activation of extracellular signal-regulated kinase(ERK),p38 kinase,and c-Jun N-terminal kinase(JNK) phosphorylation,and down-regulation of Akt phosphorylation was observed.CONCLUSION:COE induces mitochondrial-mediated,caspase-dependent apoptosis in HCCLM6 cells,which might be attributed to the activation of mitogen-activated protein kinase(MAPK) and inhibition of Akt signaling pathways.These data suggest that COE may be a potential treatment for human hepatocellular carcinoma. | Hua Zhang Yayun Qian Yanqing Liu Guoqing Li Pingfang Cui Yaodong Zhu Hui Ma Xue Ji Shiyu Guo Hisamits Tadashi | 2012 | Journal of Traditional Chinese Medicine2012，32，4： | 18 |
| 2 | Attenuated phenotypes and analysis of a herpes simplex virus 1strain with partial deletion of the UL7, UL41 and LAT genes显示文摘We previously constructed a herpes simplex virus 1(HSV-1) UL7 mutant virus(M1) and showed that a partial deletion mutation of the UL7 gene led to a lower proliferative rate and an attenuated phenotype. Using the M1 mutant, we further modified the UL41 gene, which encodes another tegument protein, and the latency-associated transcript(LAT) gene. Observations of the resulting mutants with modified UL7 and UL41(M2) or UL7, UL41 and LAT(M3) genes indicated attenuated phenotypes, with lower proliferative ratios in various cells, non-lethal infections in mice and lower viral loads in nervous tissues compared with the wild-type strain. Furthermore, no LAT stable intron could be detected in the trigeminal ganglion of M3-infected animals. The results obtained with the three HSV-1 mutants indicate that the M3 mutant is an attenuated strain with low pathogenicity during both acute and latent infections. Together, the results support the use of the M3 mutant as a candidate for the development of an HSV-1 vaccine. | Xingli Xu Yingqiu Guo Shengtao Fan Pingfang Cui Min Feng Lichun Wang Ying Zhang Yun Liao Xiaolong Zhang Qihan Li | 2017 | Virologica Sinica2017，32，5： | 6 |
| 3 | A comparative study of the characteristics of two Coxsackie A virus type 16 strains (genotype B)显示文摘Coxsackie A virus is one of the major pathogens associated with hand, foot and mouth disease (HFMD). The etiological characteristics of Coxsackie A virus type 16 (CA16) are thought to correlate with the pathological process of its infection. Two CA16 strains that were isolated from a severe HFMD patient presented with different plaque forms. This observation, along with biological analysis, indicated that the differences in the strains' biological characteristics, such as proliferation kinetics and immunogenicity, correlate with differences in their pathogenicity toward neonatal mice. Furthermore, these differences are thought to be associated with the sequence of the 5′ non-coding region of the viral genome and the VP1 structural region sequence. The results suggest that the biological and genetic characteristics of the CA16 viral strains are relevant to their pathogenicity. | YANG ErXia ZHAO Heng ZHANG Ying LIU JianSheng LIAO Yun WANG LiChun CUI PingFang YANG LiXian LIU LongDing DONG ChengHong DONG ShaoZhong SHAO CongWen JIANG Li SUN Le LI QiHan | 2012 | Science China(Life Sciences)2012，55，4： | 5 |
