LAG3 and hepatocellular carcinoma: To determine whether there is association between RCOR members and some immune checkpoint genes, we categorized the HCC samples into high and low groups in terms of median expression value of RCORs, then compared the expression of immune checkpoint molecules (CD274, CTLA-4, LAG-3, LGALS9, HAVCR2, PDCD1, PDCD1LG2) between different groups of RCORs.
