Pyridine nucleotide biosynthetic process

Across TCGA patient cohorts, RNA activity of the Pyridine nucleotide biosynthetic process pathway is significantly associated with the RNA expression of multiple genes, with the BRCA cohort showing a particularly strong set of associations.

The most reproducible pathway-associated genes across cancer lineages are PTPN7, GZMA, and RTP4, each associated with the pathway in up to 6 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, Pyridine nucleotide biosynthetic process activity versus PTPN7 in BRCA (Pearson r = 0.38).

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.
