OSKM誘導(dǎo)過(guò)表達(dá)c-Jun肝癌細(xì)胞重編程
[Abstract]:Objective to construct OSKM induced reprogramming cell line of c-Jun cells (C3A-c-Jun) and to investigate the effect of exogenous c-Jun on reprogramming of hepatoma cells. Methods after overexpression of c-Jun in C3A cells, OSKM induction reprogramming was carried out, and C3A-c-Jun induced tumor stem cell line C3A-c-Jun-i CSCs. was established by using alkaline phosphatase staining and real-time PCR, immunoblotting, immunofluorescence and other techniques. Results the C3A-c-Jun-i CSCs clones were domed and obtuse at the edge. The cells in the clones were small and tightly arranged and distributed in multiple layers. The expression of exogenous and endogenous Sox2 in OCT4,SOX2;C3A-c-Jun-i CSCs group was significantly higher than that in C3A-i CSCs control group, and the expression of c-Jun continued during reprogramming. Conclusion OSKM induces reprogramming of C3A- C3A-c-Jun hepatoma cells and establishes C3A-i CSCs and C3A-c-Jun-i CSCs cell lines respectively. It is found that exogenous c-Jun promotes the reprogramming process of HCC cells by up-regulating the expression of Sox2 gene and initiating a series of downstream reactions.
