Across TCGA pan-cancer cohorts, PPP1R1C mass-spec protein is linked to patient survival in 1 of 34 cancer types, making it a survival-associated PPP1R1C data layer compared with 26 for mass-spec protein and 3 for mutation status.
The strongest signal is observed in glioblastoma multiforme (GBM), where higher PPP1R1C mass-spec protein is associated with worse disease-free survival. In most high-consensus cancer types, elevated PPP1R1C expression acts as an unfavorable survival marker.
GBM are the cancer types where PPP1R1C mass-spec protein most reproducibly stratifies survival.
