Positive regulation of membrane protein ectodomain proteolysis

Across TCGA cell cohorts, RNA activity of the Positive regulation of membrane protein ectodomain proteolysis pathway is significantly associated with the shRNA dependency of multiple genes, with the URINARY_TRACT cohort showing a particularly strong set of associations.

The most reproducible pathway-associated genes across cancer lineages are SNX9, UBR7, and FURIN, each associated with the pathway in up to 8 cancer types. Since the analysis shows associations rather than directional relationships, both pathway-to-partner and partner-to-pathway views are reported.

Each partner is linked to its corresponding Q-omics profile. The box plot shows the strongest association, SNX9 grouped by Positive regulation of membrane protein ectodomain proteolysis-low versus -high activity in URINARY_TRACT.

Pathway-associated genes by consensus

Ranked by combined sampling and lineage consensus. X-score (pathway→partner) and Y-score (partner→pathway) are standardized regression coefficients; both directions are reported because the association is undirected. The reported p-values are derived from the association test.
