We observed a positive correlation between CKMT1A expression and cancer pathological stages in LUAD and UCEC (Fig. 1d, all P < 0.05), and a negative correlation in ESCA and KIRP (Fig. 1d, all P < 0.05), the violin plots of other cancers were show in Fig. S1b (Additional file 1 Fig. S1b). This evidence concerns the gene CKMT1A and cancer.
