SCARA5 and lung cancer: In order to explore the mechanistic basis for the effect of SCARA5 on lung cancer, we divided the samples of GEO datasets GSE12667 and GSE2109 into two categories according to the median expression of SCARA5 (Figure 4A), and Gene Set Enrichment Analysis (GSEA) was performed with the GEO datasets GSE12667 and GSE2109.
