Purine nucleoside diphosphate biosynthetic process

Across TCGA patient cohorts, RNA activity of the Purine nucleoside diphosphate biosynthetic process pathway is significantly associated with the protein abundance of multiple proteins, with the OV cohort showing a particularly strong set of associations.

The most reproducible pathway-associated proteins across cancer lineages are AK4, FKBP7, and SGCD, each associated with the pathway in up to 9 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 scatter plot shows the strongest association, Purine nucleoside diphosphate biosynthetic process activity versus AK4 in OV (Pearson r = 0.36).

Pathway-associated proteins 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.
