NCOA5 knockout suppresses epithelial-to-mesenchymal transition (EMT) impairing cell proliferation and migration in Hepatocellular Carcinoma cells

Nuclear receptor coactivator 5 (NCOA5) is an AF2-independent coactivator that contains both transcriptional activation and repression domains. Previous studies have shown that NCOA5 plays an important role in the development of a variety of malignancies. However, the underlying mechanisms remain unclear. In our study, we successfully generated the NCOA5 knockout liver cancer cell lines by CRISPR/Cas9 -mediated genome editing and found that NCOA5 knockout inhibited the proliferation and migration of hepatocellular carcinoma (HCC) cells significantly, meanwhile led to a marked decrease in tumor microsphere formation. Furthermore, mechanistic analyses indicated that NCOA5 knockout can inhibit the EMT process. In this study, knocking out NCOA5 in hepatoma cells LM3 with CRISPR/Cas9 provides an important cellular model for studying role of NCOA5 in HCC. In conclusion , Oour study provides new insights and evidence that NOCA5 was significantly correlated with the progression of HCC and was particularly involved in EMT. Overall design: Hepatocellular Carcinoma cells mRNA profiles of wide type(WT) and NCOA5 knockout LM3 cells were generated by deep sequencing, using Illumina HiSeq.
