Mitogen-activated protein kinases (MAPKs) including extracellular signal-regulated kinase (ERK), Jun N-terminal kinase (JNK), and p38 are important in the inflammatory response [27], and DJ-1 has been reported to influence their activity in some types of cells such as cancer cells, neurons, or astrocytes [28–32]. The gene discussed is WNK2; the disease is cancer.
