Nuclear factor-KB signaling pathway and gender differences in alcoholic liver fibrosis / 解剖学报

Objective To investigate the relationship between nuclear factor(NF)-κB signaling pathway and gender differences in alcoholic liver fibrosis. Methods C57BL/6 N mice at 7-8 weeks of age were randomly divided into: male normal group, male model group, female normal group and female model group of 20 mice each. The normal group was fed with control liquid diet for 8 weeks, and the model group was fed with alcoholic liquid diet for 8 weeks combined with 31.5% ethanol gavage (5g/kg twice a week) to establish an alcoholic liver fibrosis model. The mice were executed at the end of 8 weekends, and the alanine aminotransferase (ALT), aspartate aminotransferase (AST) activity, estradiol (E

Changes of Alternative Splice Variant of the SRSF12 by Cisplatin in Multiple Cells / 昆明医科大学学报

Objective To detect the changes of mRNA isoforms in multiple cancer cell lines with dose of cisplatin. Methods Total RNA of the cells treated by cisplatin were abstracted 24 h after the treatment. mRNA isoforms of SRSF12 gene were detected by semiquantitative RT-PCR. The ratios of mRNA isoforms were analyzed by gel image software and statistical analysis. Results Under the cisplatin treatment, 2 mRNA isoforms of SRSF12 were detected in five cells except Caski cells,their ratios and relative mRNA levels were changed. With the increase of dose of cisplatin, the ratio of isoform-a was slightly increased; but the ratio of isoform-b was different, the changes were not obvious in the A549 and 293FT cells, the weaker expression was expressed in the H1299 and C33A cells, and the two isoforms were gradually weakening in the Siha cells. Conclution Under the cisplatin treatment in multiple cancer cells, the expression of SRSF12 shows tissue-specific and cell type-specific patterns .
