SEM1

Across TCGA pan-cancer cohorts, SEM1 mass-spec protein is linked to patient survival in 2 of 34 cancer types, making it a survival-associated SEM1 data layer compared with 23 for mass-spec protein and 5 for mutation status.

The strongest signal is observed in head and neck squamous cell carcinoma (HNSC), where higher SEM1 mass-spec protein is associated with better disease-free survival. In most high-consensus cancer types, elevated SEM1 expression acts as an unfavorable survival marker, although some lineages such as HNSC and LSCC show a favorable association.

HNSC and LSCC are the cancer types where SEM1 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.
