KAT2B and cancer: Firstly, PCAF is a direct target of several microRNAs (miRNAs), such as miR-181a/b, miR-17, miR-32, miR-106b, and miR-25, which use a plethora of mechanisms to affect PCAF protein levels, e.g., they trigger its degradation or decrease its translational rate in both cancer and normal cells [76,77,78].
