The analysis data showed that H2BC9 mRNA expression level was positively correlated with the mRNA expression levels of marker genes in neutrophils, eosinophils, M1 macrophages T cells, myeloid-derived suppressor cell (MDSC) in glioma, and negatively correlated with the mRNA expression levels of marker genes in NKT cells and cDC2s cells. The gene discussed is H2BC9; the disease is central nervous system cancer.
