MAPK8 and colon adenocarcinoma: Finally, we validated the function of the key genes by receiver operating characteristic (ROC) curve analysis, multivariate cox proportional hazards model and COAD cell lines.<h4>Results</h4>There is a strong association between the 4 key genes (UCHL1, HSPA1A, MAPK8, and PLEC) of COAD and the necroptotic&mitophagy, which were found to be lowly mRNA level in COAD cell lines.
