ERRFI1 and hepatocellular carcinoma: Additionally, ERRFI1 is deeply involved in various physiological and pathogenic events, such as lung development [78], endometrial epithelial cell proliferation [79], lung tumorigenesis [80–82], gliomagenesis [83, 84], hepatocellular carcinoma [85, 86], and neointimal hyperplasia in vascular smooth muscle cells [87].
