The breast cancer STRING network where Chi Square χ2 ≥ 15 from fully tryptic peptides. Breast cancer tryptic peptide frequency difference greater than 15 and χ2 value greater than 15 at degrees of freedom of 1 (p < 0.0001). Network Stats: number of nodes, 173; number of edges, 260; average node degree, 3.01; avg. local clustering coefficient, 0.378; expected number of edges, 206; PPI enrichment p-value, 0.000175
