Notably, we observed a significant positive correlation between MSI2 expression and ADAR1 expression but a negative correlation between SLC38A4 expression reported in publicly available (TCGA_LIHC, ICGC_LIRI, and GSE77314) and our multistage liver cancer (Catholic_mLIHC; GSE114564) datasets (Supplementary Fig. 8). This evidence concerns the gene MSI2 and liver cancer.
