Published: 16 November 2013
FIG. 5. PDCD4 deficiency attenuates WAT inflammation in HFD-fed mice. WT and PDCD4−/− mice were fed a ND or HFD for 24 weeks. The macrophage infiltration in epididymal adipose tissues and inflammatory cytokine secretion by epididymal adipose tissue explants were detected. (A) Immunohistochemical study (CD68 staining) and (B) percentage of CD68+ macrophages on sections from epididymal adipose tissues (n ≥ 3 mice/condition); the arrows indicate inflammation. Original magnification is 200, scale bar is 50 μm. (C) Representative data of cytometric bead array immunoassay and (DI) statistical data for inflammation detection on supernatants from cultured epididymal adipose tissue explants (n = 4–9 mice/group). Data are presented as mean ± SEM. IFN-γ, interferon-γ; MCP, monocyte chemoattractant protein. *P < 0.05, **P < 0.01, ***P < 0.001. FIG. 5.
