For the relationship between hub genes expression levels and the prognosis of NSCLC from Kaplan Meier Plotter, COL3A1, COL1A2, OGN, COL15A1, ASPN, and MXRA5 were associated with the overall survival of LUAD (Figure 8A), but the expression levels of these genes did not affect overall survival of LUSC patients. The gene discussed is COL1A2; the disease is non-small cell lung carcinoma.
