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. Hepatocellular Carcinoma cells mRNA profiles of wide type(WT) and NCOA5 knockout LM3 cells were generated by deep sequencing, using Illumina HiSeq.
