Expression data from hepatocellular carcinoma cell lines

In this study, we demonstrated that mitochondrial respiratory defect enhanced NFE2L1 transcription via reactive oxygen species (ROS)-mediated STAT3 activation and the up-expressed NFE2L1 increased hepatoma cell invasiveness by inducing syntaxin 12 (STX12) expression. Bioinformatic analysis of The Cancer Genome Atlas Liver Hepatocellular carcinoma (TCGA-LIHC) open database showed that NFE2L1 expression is strongly positively correlated with STX12 expression and, furthermore, epithelial-mesenchymal transition (EMT)-related core genes were significantly upregulated in the tumors expressing both NFE2L1 and STX12. The effect of NFE2L1/STX12 axis on lung metastasis of hepatoma cell was proved in nude mice model. Collectively, our results indicate that NFE2L1 was a key mitochondrial retrograde signaling-mediated primary gene product to enhance hepatoma cell invasiveness via STX12 expression
