Figure 1c showed the total MEIS1 protein expression in breast cancer, colon cancer, LUAD, UCEC and ccRCC was higher than that in normal tissues (p < 0.001). Figure 1d revealed the correlation between pathological stages and MEIS1 expression levels, including ACC, COAD, KIRC, KIRP, and LIHC (p < 0.05). The correlation between pathological stages and MEIS1 expression levels in other cancer types with no statistical significance were shown in Figure S4. Here, MEIS1 is linked to breast cancer.
