Fig. 3From: PHLPP isoforms differentially regulate Akt isoforms and AS160 affecting neuronal insulin signaling and insulin resistance via ScribbleEffect of PHLPP2 silencing on PHLPP isoforms, Akt isoforms and AS160 in insulin signaling and insulin resistant condition in neuronal cells (N2A). Three days post-proliferation, PHLPP2 was silenced using PHLPP2 specific siRNA. N2A cells were differentiated in serum-free medium in the absence of (MF) or chronic presence of 100 nM insulin (MFI) for 3 days. Cells were lysed and subjected to western blotting, followed by probing with relevant primary antibodies. A Bar represents relative change in PHLPP2 probed with anti-PHLPP2 antibody. B Bar represents relative change in PHLPP1 probed with anti-PHLPP1 antibody. C Bar represents relative change in pAkt1 (Ser-473) probed with anti-Akt1 antibody. D Bar represents relative change in pAkt2 (Ser-474) probed with anti-Akt2 antibody. E Post-insulin stimulation, lysates were subjected to immunoprecipitation using anti-Akt3 antibody. Bar represents relative change in pAkt (Ser-473) probed with anti-Akt3 antibody. F Bar represents relative change in pAS160 (Ser-588) when probed with anti-AS160 antibody. G Bar represents relative change in pAS160 (Thr-642) when probed with anti-AS160 antibody. GAPDH has been used as a loading control. Experiments were executed three times and a representative result is shown. Data expressed are mean ± SE. ***P < 0.001, **P < 0.01, *P < 0.05 compared to lane 1, ###P < 0.001, ##P < 0.01, #P < 0.05 as compared to lane 2, $$P < 0.01 compared to lane 6 IB Immunoblot; IP ImmunoprecipitationBack to article page
