Figure 4. PI3K-Akt signaling pathway was activated upon AA treatment.

Figure 4

(A) Examination of Akt activation. NRK-49f cells were incubated with 0 and 12 µM AA for 1, 3 and 6 h. The phosphorylated activation form of Akt was detected by immunoblotting. (B) The levels of phosphorylated PDK1 and PI3K-p85 were evaluated by Western Blot at indicated periods of AA treatment. (C) The interaction of phosph-PDK1 with Akt. After 1 h of 0 and 12 µM AA treatments, cells were immunoprecipitated with anti-Akt antibody. The immunoprecipitated pellets were further immnoblotted with anti-phospho PDK1 or anti-Akt antibody. The input and mouse IgG were served as positive and negative control, respectively.
