The results showed that the expression of GINS2 is negatively correlated with CAF abundance in most cancer types in BRCA, COAD, GBM, HNSC, LUAD, LUSC, OV, PAAD, PCPG, READ, SARC, STAD, THCA, THYM, and UCEC tumours extracted from TCGA database; the expression of GINS2 is negatively correlated with the infiltration of CAFs. The gene discussed is GINS2; the disease is glioblastoma.
