Comparisons of browning in visceral white adipose tissue. (A) Histological analyses of epididymal WAT (eWAT) by H&E staining. (B) qPCR analyses of representative brown genes expression in eWAT. (C) qPCR analyses of adipocyte markers and representative white genes expression in eWAT. (D) qPCR analyses of expression of browning regulators in eWAT. *: p < 0.05, **: p < 0.01 for 129/Sv vs. C57BL/6; Δ: p < 0.05, ΔΔ: p < 0.01 for FVB/D vs. C57BL/6, n = 8, 8, 8.
