LncRNA HOTAIR Enhances Epithelial-to-mesenchymal Transition to Promote the Migration and Invasion of Liver Cancer by Regulating NUAK1 via Epigenetic Inhibition miR-145-5p Expression.

LncRNA HOTAIR play important roles in the epigenetic regulation of carcinogenesis and progression in liver cancer. Previous studies suggest that the overexpression of HOTAIR predicts poor prognosis. In this study, through transcriptome sequencing data and experiments, we found that HOTAIR were more highly expressed and there is significantly positive relationship between HOTAIR and NUAK1 in liver cancer tissues and cell lines.

Inhibition of TIGAR Increases Exogenous p53 and Cisplatin Combination Sensitivity in Lung Cancer Cells by Regulating Glycolytic Flux.

The metabolism and apoptosis of tumor cells are important factors that increase their sensitivity to chemotherapeutic drugs. p53 and cisplatin not only induce tumor cell apoptosis, but also regulate the tumor cell metabolism. The TP53-induced glycolysis and apoptosis regulator (TIGAR) can inhibit glycolysis and promote more glucose metabolism in the pentose phosphate pathway.

Androgen receptor splicing variant 7 (ARv7) promotes DNA damage response in prostate cancer cells.

In the treatment of patients with locally advanced prostate cancer (PCa), androgen deprivation therapy (ADT) significantly enhances the efficacy of radiotherapy by weakening the DNA damage response (DDR) pathway. Recently, several studies have suggested that androgen receptor splicing variants (ARvs) may mediate a compensatory DDR pathway when canonical androgen receptor (AR) signaling is inhibited, thus contributing to the resistance of some patients to this combinational treatment. However, the specific roles of certain ARvs as well as the detailed mechanism of how ARvs regulate the DDR are not well understood.
