Analyses of the impact of ERK5 protein expression on patient survival in the patient cohort, which included patients with all sarcoma types analyzed with clinical follow-up data (n = 55), showed a significant negative relationship between ERK5 expression and patient survival (p-value = 0.0295, HR = 0.05086 (0.2599–0.9956)) (Fig. 3e). Here, MAPK7 is linked to sarcoma.
