SEMA3G

Across TCGA pan-cancer cohorts, SEMA3G mass-spec protein differs between tumor and matched normal tissue in 2 of 18 cancer types tested, making tumor–normal expression one of SEMA3G’s most consistent transcriptional readouts.

The strongest signal is observed in lung squamous cell carcinoma (LSCC), where SEMA3G mass-spec protein is repressed in tumor relative to normal tissue. In most cancer types SEMA3G is over-expressed in tumor, although a few such as LSCC and LUAD show the opposite, repressed pattern.

LSCC and LUAD are the cancer types where SEMA3G 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 SEMA3G mass-spec protein (log₂); positive values indicate higher expression in tumor. p-values are from the differential-expression test.
