(G and H) Cells were pretreated with N-AC (G) or DPI (G) for 1 h followed by treatment with gAcrp (1 μg/ml) for additional 24 h. Cytosolic and nuclear protein fractions were prepared as described previously and the expression level of FoxO3A in each fraction was determined by Western blot analysis. Images are representative of three separate experiments that showed similar results along with β-actin and laminB1 as internal loading control for each fraction. Densitometric analysis was performed to quantitate protein and is shown in the graph (lower panel) and values are presented as mean ± S.E.M.

(A) Cells were treated with gAcrp (1 μg/ml) for indicated time periods. SIRT1 protein expression was determined by Western blot analysis as described previously. (B and C) Cells were pretreated with N-AC (B) or DPI (C) for 1 h followed by treatment with gAcrp (1 μg/ml) for additional 8 h. Western blot analysis was performed to determine SIRT1 protein expression level. Representative images of three independent experiments are shown, keeping β-actin as an internal loading control. Quantitative analysis for SIRT1 expression was performed by densitometric analysis and presented as mean ± S.E.M.

(Lower panel) After transfection with SIRT1 siRNA or scrambled siRNA, cells were treated with gAcrp (1 μg/ml) for 24 h. FoxO3A protein expression levels in cytosol and nucleus were determined by Western blot analysis along with β-actin and lamin B1 as internal loading control for cytosolic and nuclear respectively.

LPS treatment induces increase in TNF-α expression in macrophages via activation of TLR4 signaling, including TRAF6 induction, MKK-6 activation, p38MAPK phosphorylation and transcriptional activation of NF-κB. Treatment of macrophages with globular adiponectin causes expression of genes related with autophagy, including LC3II and Atg5, through activation of FoxO3A signaling, which is dependent on ROS production and SIRT1 expression. The autophagosome formation by gAcrp causes sequestration and degradation of TRAF6, further dampens the LPS-activated TLR4 signaling by inhibition of phosphorylation of p38MAPK, leading to the inhibition of LPS-stimulated TNF-α expression. Detailed molecular mechanism explaining how autophagy degrades TRAF6 and inhibits p38MAPK phosphorylation remained to be determined.
