AKT activity and levels of endogenous phospho-substrates of AKT are increased in Jade-1-silenced HK-2 cells. A. Endogenous AKT was immunoprecipitated from cellular extracts of HK-2 stable cell lines and then incubated with purified GSK3β substrate. The amount of phosphorylated GSK3β S9 was assessed by immunoblotting. B. Cell lysates from HK-2 cell lines were probed with a phospho-AKT substrate antibody. C. Levels of endogenous phospho-GSK3β S9, a known substrate of phospho-AKT, were assessed by immunoblot. D. Levels of endogenous p21 in the HK-2 cell lines were assessed without or with LY294002.
