OCIAD2 and neoplasm: Furthermore, pathway enrichmentanalysis was conducted on the proteomic data derived from our cohort to determine the biofunctions of OCIAD2 andthe OCIAD2-mediated signaling pathways in tumor initiation and progression.Furthermore, the mitochondrial metabolic change induced by the alterationof the OCIAD2 was measured to explore the functional role of theOCIAD2 in mitochondria-related pathways in lung adenocarcinoma.
