PFOA exposure increased insulin sensitivity in the livers and muscles of mice.
(a) Western blots of liver, muscle and white adipose tissues (WATs) lysates prepared from PFOA-exposed mice treated with insulin with antibodies of phosphorylated and total PTEN, AKT and GSK3β. (b) Relative fold change of band densities from livers (n = 3). (c) Relative fold change of band densities from muscles (n = 3). (d) Relative fold change of band densities from WATs (n = 3). Data are means ± SE. Significantly different from control group (*p < 0.05, **p < 0.01, N.S., not significant).
