Using expression data of 375 GC tissues from the TCGA database, we detected a positive correlation between RNF144A-AS1 and LOX either (R2 = 0.2714, P < 0.001), which was consistent with the result from GC cells (R2 = 0.7135, P < 0.001) (Fig. 5I, J). The gene discussed is RNF144A; the disease is gastric cancer.
