Expression and OS curves of 12 collagen family genes are plotted for GC in GEPIA. Expression on boxplots: A COL1A1, C COL2A1, E COL3A1, G COL4A1, I COL5A1, K COL6A1, M COL7A1, O COL8A1, Q COL9A1, S COL10A1, U COL11A1, W COL12A1. Overall survival on curve diagrams: B COL1A1, D COL2A1, F COL3A1, H COL4A1, J COL5A1, L COL6A1, N COL7A1, P COL8A1, R COL9A1, T COL10A1, V COL11A1, X COL12A1. Y The COL1A1, COL4A1 and COL12A1 mRNA expression within GC cells and healthy cells. *P < 0.05, **P < 0.01 GC group vs normal group
