Inhibiting PI3K/Akt with LY294002, Capivasertib (AZD5363), or using an inactive Akt mutant significantly increased p35 expression and subsequently enhanced AR stability and activation in PCa cells. Importantly, CDK5 knockdown further reduced PI3K/Akt-inhibition-induced AR and cell viability maintenance, suggesting a compensatory role for CDK5-AR in maintaining cell viability under Akt inhibition. In conclusion, PI3K/Akt inhibition could trigger p35-CDK5-dependent AR activation and cell viability, highlighting p35-CDK5 as a critical link connecting PI3K/Akt inhibition to AR activation and pivotal in PCa cell resistance to PI3K/Akt blockade.
