Mitogenic‐activated protein kinase (MAPK)/extracellular signal‐regulated kinase (ERK) signaling pathway has been found to play a role in some cancer therapies, as ERK1/2, one of MAPK/ERK kinases, was highly expressed in cervical cancer tissues 13, which also regulates many biological factors that affect types of miRNAs and their relevant machinery 14. The gene discussed is MAPK1; the disease is cancer.
