Zhang et al. identified 16 endoplasmic reticulum (ER) stress-related genes (CYP2E1, SLN, BRCA1, CISD2, LRRK2, BMP2, MYH7, HSPB1, DNM1L, SHISA5, RNF185, RCN1, SPP1, RPN2, PDIA3 and ATP2A2), and established an ER stress risk model based on The Cancer Genome Atlas (TCGA) glioma database to reflect the immune characteristics and predict the prognosis of glioma patients [18]. The gene discussed is CYP2E1; the disease is central nervous system cancer.
