IL-6干預(yù)下HBx基因?qū)02細(xì)胞增殖影響的研究
[Abstract]:Objective (1) to construct a L02-HBx cell model with stable expression of HBx gene. The aim of this study was to explore the physicochemical and biological properties of HBx protein and its relationship with the occurrence and outcome of (HCC) in hepatocellular carcinoma. (2) to observe the growth trend of L-02 cells infected with HBx after co-culture of exogenous IL-6. Cell cycle changes, In order to explore whether IL-6 can promote liver regeneration or improve liver cirrhosis, we hope to provide new target and theoretical basis of cytokine therapy for patients with hepatitis B virus infection. Methods (1) A dose-response assay was designed to investigate the lowest lethal concentration of purine mycin against L-02. (2) L02 cell line expressing HBx stably was established by lentivirus vector method. L02-HBx cells were screened with the lowest lethal concentration of purine mycin to obtain positive clones, L02-HBx cells were amplified and cultured, and L02-con and L02 cells were used as controls. Fluorescence quantitative RT-PCR and protein imprinting Western blot technique were used to detect the transcription of HBxDNA and the translation of HBx protein, so as to ensure that the L02 cell model infected by HBx was successfully constructed. (3) L02-HBx cells were co-cultured with IL-6. L02-HBx cells of the same transmission algebra were cultured without IL-6 synchronously as negative control of L02-HBx cells. The morphological characteristics of L02-HBx cells in each group were observed by inverted phase-contrast microscope with high configuration, and the proliferation of L02-HBx cells in each group was detected and compared by CCK8 method. At the same time, flow cytometry was used to detect the cell cycle and the proportion of the cells in each cell cycle to the total number of cells, so as to analyze and compare the cell proliferation and the similarities and differences of cell cycle in each group. Results (1) the results of dose-response analysis of purine mycin showed that purine mycin at concentration of 400-1000ng/ml killed all of the cultured L02 cells, while cells survived below 400ng/ml. Therefore, 400ng/ml was the lowest lethal concentration of purine mycin to screen L02 cells. (2) after 5-7 days of 400ng/ml purine mycin screening and transfection of HBx L02 cells, the positive cells were cloned, and L02-con and L02 cells were used as control group. The expression of HBx DNA was detected by reverse transcription polymerase chain reaction (RT-PCR), and the translation of HBx protein was detected by Western blot. (3) under inverted phase contrast microscope, the growth pattern of L02-HBx cells co-cultured with engineering L-6 was different from that of control cells. The boundary of CCK8 was not clear. The results of CCK8 further showed that the growth of L02-HBx cells was inhibited after co-culture with IL-6. Compared with the control group, the percentage of S phase cells in L02-HBx cells was significantly decreased, while that in G 2 / M phase was significantly increased. Conclusion (1) the L02-HBx cell model with stable expression of HBx gene was successfully constructed. It lays a solid foundation for further exploring the physicochemical and biological properties of HBx protein and its relationship with the development and transformation of HCC in primary liver cancer. (2) the generation of L02-HBx cells in exogenous IL-6 co-culture environment. The length is obviously suppressed, G 2 / M arrest occurs in cell cycle, which may lead to mutation and mutagenesis, which eventually leads to malignant change and carcinogenesis. It also reveals that the most important point is that HBX may play a specific biological effect in its specific environment.
