The PPM1G mRNA expression in patients with liver cancer was significantly higher than that in normal controls in the following datasets: GSE22058 [17], GSE25097 [18], GSE36376 [19], GSE14520 (GPL3721 subset) [20], GSE10143 [21], GSE54236 [22], GSE63898 [23], GSE64041 [24], GSE76427 [25] (which from GEO database), TCGA-LIHC(which from TCGA data), and Liver Cancer-RIKEN, JP Project from International Cancer Genome Consortium (ICGC-LIRI-JP) (which from ICGC database) (Figure 2A). The gene discussed is PPM1G; the disease is liver cancer.
