Across TCGA pan-cancer cohorts, SFI1 mass-spec protein differs between tumor and matched normal tissue in 2 of 18 cancer types tested, making tumor–normal expression one of SFI1’s most consistent transcriptional readouts.

The strongest signal is observed in lung adenocarcinoma (LUAD), where SFI1 mass-spec protein is more highly expressed in tumor relative to normal tissue. In most cancer types SFI1 is over-expressed in tumor.

LUAD and CCRCC are the cancer types where SFI1 tumor–normal differential expression is most reproducible.

mass-spec protein tumor vs normal associations by lineage

Ranked by sampling consensus. Fold-change is the tumor-versus-normal difference in SFI1 mass-spec protein (log₂); positive values indicate higher expression in tumor. p-values are from the differential-expression test.
