A number of studies have reported on RBM10 with respect to lung adenocarcinoma, colorectal cancer, pancreatic cancer, endometrial cancer, and the relationship between malignant tumors such as breast cancer, but most of the research has mainly focused on RBM10 in studies on the function and mechanism of action of tumors; thus, the effect of the tumor microenvironment on tumor immune regulation and drug sensitivity is unclear [21]. The gene discussed is RBM10; the disease is breast cancer.
