Combining the feature with the level of CDKN1B expression in various tumors, it was discovered that CDKN1B expression was significantly correlated with estimated infiltration values of CAFs from TCGA tumors, including CESC, COAD, HNSC, HNSC with negative human papillomavirus (HPV−)], LUAD, PAAD, STAD, and TGCT, but negatively correlated with GBM [36]. Here, CDKN1B is linked to glioblastoma.
