RCL1 and hepatocellular carcinoma: For 9 HCC datasets including GSE22058 (Fig. 2A), GSE25097 (Fig. 2B), GSE36376 (Fig. 2C), GSE14520 (Fig. 2D), GSE54236 (Fig. 2F), ICGC-LIR-JP (Fig. 2G), GSE63898 (Fig. 2I), TCGA-LIHC (Fig. 2J), and GSE76427 (Fig. 2K), the expression levels of Rcl1 in HCC tissues were generally lower than the ones in adjacent tissues (p < 0.001).
