HDAC6 and cancer: We also analyzed the correlation between CSNK2B expression and HDAC family‐related genes in the TIMER2.0 public database of multi‐cancer, and we found that the expression of CSNK2B showed a positive correlation with HDAC1, HADC2, HDAC5, HDAC6, and HDAC8 in LUAD and LUSC (Figure S10A,B, Supporting Information).
