Double-strand break repair via synthesis-dependent strand annealing

Across TCGA patient cohorts, RNA activity of the Double-strand break repair via synthesis-dependent strand annealing pathway is significantly associated with the protein abundance of multiple proteins, with the LSCC cohort showing a particularly strong set of associations.

The most reproducible pathway-associated proteins across cancer lineages are RFC2, RRM1, and SMC2, each associated with the pathway in up to 10 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, Double-strand break repair via synthesis-dependent strand annealing activity versus RFC2 in LSCC (Pearson r = 0.60).

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.
