In agreement with these results, by analyzing an additional 56 cases HCC samples, we found that RARγ expression is overexpressed in tumor tissues (Fig. 1c and d), and further upregulated in those with lymph node metastasis (LNM) (Fig. 1e and f), suggesting RARγ’s potential role in invasive progression of HCC. This evidence concerns the gene RARG and neoplasm.
