AKT3-174aa competitively interacts with p-PDK1 form ATK2/3. a PDK1 kinase activity was determined in U251 and U373 cells with circ-AKT3 overexpression and their control cells at the indicated time point. Error bars represent three independent experiments, **, p < 0.01. b Upper, AKT kinase activity was determined in U251 and U373 cells with circ-AKT3 overexpression and their control cells (48 h); or in SW1783 and Hs683 cells with circ-AKT3 knocking down and their control cells (48 h). Error bars represent three independent experiments, *, p < 0.05, **, p < 0.01. Lower, p-SGK level was determined in indicated cells. c U251 cells were transfected with increasingly dose of circ-AKT3. IP was performed by using AKT2, AKT3 and p-PDK1 antibodies and followed by immunoblot using indicated antibodies. d SW1783 cells were transfected with increasingly dose of circ-AKT3 shRNA. IP was performed by using AKT2, AKT3 and p-PDK1 antibodies and followed by immunoblot using indicated antibodies
