The survival analysis using GEPIA2 revealed that low expression of six genes, namely KNG1, ACTN2, VCAM1, MYDN, COL6A2, and ACTC1, was significantly associated with poor overall survival (OS) and represented cancer risk factors (P < 0.05, HR > 1, group cutoff = median, (Figure 6A). This evidence concerns the gene KNG1 and cancer.
