Figure 1. Overexpression of MAPK4 in a subset of human cancers is associated with decreased overall survival and increased AKT activity.

Figure 1

(A) Upper panel, MAPK4 mRNA expression across 8887 tumors of various histological subtypes from The Cancer Genome Atlas (TCGA). Lower panel, Kaplan-Meier plot of overall survival in patients across all TCGA data sets, as stratified by high MAPK4 expression. P values by log-rank test and by stratified log-rank test (correcting for tumor type), as indicated. (B) Kaplan-Meier plot of overall survival in patients within specific cancer types, as stratified by high MAPK4 expression. BLCA, bladder cancer; LGG, low-grade glioma; LUAD, lung adenocarcinoma; THCA, thyroid carcinoma. P values by log-rank test. (C) Heatmaps showing the correlation of MAPK4 expression with expression of specific proteins profiled in TCGA pan-cancer datasets by Pearson’s coefficient. Significance of correlation: P < 1 × 10–17 for each protein feature.
