ERRFI1 Induces Apoptosis of Hepatocellular Carcinoma Cells in Response to Tryptophan Deficiency

The authors showed that ERRFI1 was upregulated in sensitive hepatocellular carcinoma (HCC) cells, but not in resistant HCC cells, in response to tryptophan deficiency, and ERRFI1 expression level positively correlated with HCC patient overall survival.
