Subsequently, gene set enrichment analysis showed that the function of KAT5 was different from that of KAT6A, KAT6B and KAT7. The expression levels of KAT6A, KAT6B and KAT7 had significant positive correlations with cancer immune infiltrates such as B cells, CD4+ T cells and CD8+ T cells. Here, KAT5 is linked to cancer.
