PTBP1

mass-spec protein & survival
Survivalmass-specKaplan–Meier · TCGA cohorts

Across TCGA pan-cancer cohorts, PTBP1 mass-spec protein is linked to patient survival in 5 of 34 cancer types, making it a survival-associated PTBP1 data layer compared with 25 for mass-spec protein and 2 for mutation status.

The strongest signal is observed in colon adenocarcinoma (COAD), where higher PTBP1 mass-spec protein is associated with better disease-free survival. In most high-consensus cancer types, elevated PTBP1 expression acts as an unfavorable survival marker, although some lineages such as COAD and CCRCC show a favorable association.

COAD, HNSC, and CCRCC are the cancer types where PTBP1 mass-spec protein most reproducibly stratifies survival.

mass-spec protein 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.
