It is the causative agent of Japanese encephalitis with approximately 50,000 infection cases and 10,000 fatal cases annually in Asia （Erlanger et al., 2009）. Although liveattenuated JEV vaccine has been developed and used for human and pig vaccination, JE occurs epidemically or sporadically in some developing countries or even in vaccinated areas （Solomon, 2006）. Host resistance factors play an important role in the outcome of viral infection.展开更多
Liver normal cells and cancer cells co-cultured on surfaces modified by different chemical functional groups, including mercapto （-SH）, hydroxyl （-OH） and methyl （-CHz） groups.

The results showed that different cells exhibited changes in response to different surfaces. Normal cells on -SH surface exhibited the smallest contact area with mostly rounded morphology, which led to the death of cancer cells, while cancer cells could not grow on -CH3 groups, which also died. In the co-culture system, the -CH3 group exhibited its unique effect that could trigger the death of cancer cells and had no effects on normal cells. Our findings provide useful information on strategies for the design of efficient and safe regenerative medicine materials.展开更多
食管癌相关基因4(esophageal cancer related gene 4,ECRG4)是一个在基因表达和蛋白作用方式方面独具特点的抑癌基因。生物信息学分析显示ECRG4的基因结构在不同种属中十分保守,提示其在维持细胞的正常生理功能方面可能发挥着重要作用...食管癌相关基因4(esophageal cancer related gene 4,ECRG4)是一个在基因表达和蛋白作用方式方面独具特点的抑癌基因。生物信息学分析显示ECRG4的基因结构在不同种属中十分保守,提示其在维持细胞的正常生理功能方面可能发挥着重要作用。本文对ECRG4的生物学背景和其在生理条件及病理条件下的表达情况和功能进行了综述,并对ECRG4在精准医疗中的可能作用进行了讨论,以期为以ECRG4为靶点的诊断和治疗提供可能的线索。展开更多

It controls the stem cell functions by controlling a wide range of pathological and physiological processes, including development, differentiation, cellular proliferation, programmed cell death, oncogenesis and metastasis. Through either mRNA cleavage or translational repression, miRNAs alter the expression of their cognate target genes; thereby modulating cellular pathways that affect the normal functions of stem cells, turning them into cancer stem cells, a likely cause of relapse in cancer patients. This present review further emphasizes the recent discoveries on the functional analysis of miRNAs in cancer metastasis and implications on miRNA based therapy using miRNA replacement or anti-miRNA technologies in specific cancer stem cells that are required to establish their efficacy in controlling tumorigenic potential and safe therapeutics.展开更多
