Firstly, for MEA1, it was upregulated in tumor tissue, and the results of various pathways including gastric cancer, breast cancer, basal cell carcinoma, and signaling pathways regulating the pluripotency of stem cells (Figure 6B), and MEA1 was negatively correlated with the abundance of most immune cells (Figure 6I), indicating that MEA1 was involved in tumor progression. Here, MEA1 is linked to breast cancer.
