IHC was performed to detect the expression of HLA-DQA2, HOXA3, and SAA2 in glioma tissues, and high expression of HLA-DQA2, HOXA3, and SAA2 was observed in glioma tissues in the short-term group compared with that in the long-term group (Figures 10A, B). This evidence concerns the gene HLA-DQA2 and central nervous system cancer.
