Furthermore, RARγ overexpression has been observed in primary tissue samples and cell lines derived from HCC and approximately half of CCRCC patients,26, 27 indicating its potential as a target for anti‐tumour therapy. However, the relationship between RARγ expression levels in tumours and ESCC patient survival and prognosis remains unexplored territory that requires further investigation. Here, RARG is linked to hepatocellular carcinoma.
