MAPK8 and gastric cancer: To further investigate the impact of the JNK-MAPK/JUN pathway on the glycolysis regulated by uMtCK in GC cells, we first suppressed JNK-MAPK/JUN signaling pathway by added inhibitor of the JNK-MAPK/JUN signaling pathway (SP600125) in GC cells with stable overexpression of uMtCK.
