It was found that expression of BGN (HR 1.9 [1.56–2.32], P = 1.3 × 10–10) was associated with worse overall survival (OS) for gastric cancer patients, as well as MMP2 (HR 1.78 [1.47–2.16], P = 2.6 × 10–9), COL1A1 (HR 1.49 [1.22–1.81], P = 8.2 × 10–5) and FN1 (HR 1.46 1.23–1.74], P = 1.3 × 10–5) (Figure 3). The gene discussed is COL1A1; the disease is gastric cancer.
