cytochrome c oxidase subunit IIIGenealiases: COIII · MTCO3
Q-omics provides the consensus-scored MT-CO3 profile across patient tissues and cancer cell-line models. MT-CO3 expression is associated with patient survival in 22 of 34 cancer types, with the highest sampling consensus in SKCM. Among the 18 cancer types available for tumor–normal comparison, MT-CO3 is differentially expressed in 9, with the highest sampling consensus in KIRC. Additionally, MT-CO3 protein abundance shows 19,459 significant protein co-abundance associations, with the highest sampling consensus in PDAC. Together, these results highlight SKCM, KIRC, and PDAC as cancer lineages where MT-CO3 shows reproducible signals across survival, tumor–normal expression, and patient cross-omics analyses.
Every result is evaluated using two consensus scores. Sampling consensus measures how consistently a finding is reproduced within a cancer lineage across different conditions. Lineage consensus measures how broadly the result is shared across cancer types, distinguishing pan-cancer signals from lineage-specific patterns.

This table summarizes MT-CO3 survival associations across molecular data types. MT-CO3 RNA expression shows survival associations in the most cancer types (22), followed by mass-spec protein abundance (7). The rightmost column indicates the cancer type with the highest sampling consensus for each molecular layer.
This table ranks reproducible MT-CO3 RNA expression–survival associations across cancer types. High MT-CO3 expression shows unfavorable associations in SKCM, but favorable associations in PAAD, KICH, ACC, LUSC and KIRP. The SKCM Kaplan–Meier curve shows clear separation, with the high-expression group declining faster, consistent with the unfavorable association (log-rank p < 0.001). Together, the overview and detailed table identify SKCM as the clearest survival context for MT-CO3 RNA expression.
This table summarizes MT-CO3 tumor–normal expression differences by data type. RNA shows broader differences across cancer types, with a lineage consensus of 9, while mass-spec protein shows differences in 5. The strongest signals are observed in KIRC for RNA and CCRCC for protein.
This table ranks reproducible tumor–normal expression differences for MT-CO3. A negative fold-change indicates higher expression in normal tissue than in tumor tissue. MT-CO3 shows lower tumor expression in KIRC, KIRP, BRCA, COAD and LIHC and higher tumor expression in KICH. The KIRC box plot shows higher MT-CO3 RNA expression in normal versus tumor tissue (log2 FC = −1.200, t-test p < 0.001).
This table shows molecular features associated with MT-CO3 in patient tissues and cancer cell lines. In patient samples, MT-CO3 shows the broadest associations at the RNA and protein expression levels, with PDAC recurring as the lineage with the largest associated feature set. In cancer cell lines, MT-CO3 RNA and mutation anchors are most strongly linked to RNA-expression features, especially in UPPER_AERODIGESTIVE_TRACT, while CRISPR and shRNA rows add functional-dependency signals in BLOOD_Leukemia and LUNG_SCLC.
