Across TCGA pan-cancer cohorts, MT-ND4 RNA is linked to patient survival in 23 of 34 cancer types, making it the most broadly survival-associated MT-ND4 data layer compared with 6 for mass-spec protein.
The strongest signal is observed in adrenocortical carcinoma (ACC), where higher MT-ND4 RNA is associated with better disease-free survival. In most high-consensus cancer types, elevated MT-ND4 expression acts as an unfavorable survival marker, although some lineages such as ACC and KICH show a favorable association.
ACC, KICH, and KIRC are the cancer types where MT-ND4 RNA most reproducibly stratifies survival.
RNA survival associations by lineage
Ranked by sampling consensus. AUC1 and AUC2 indicate survival in the high- and low-expression groups, respectively; the lower AUC marks the poorer-surviving group. p-values are from the log-rank test.
