HFD increased the number of ERα-expressing cells. HFD increased the number of ERα-expressing cells. A, HFD increased the number of ERα-expressing cells in the ARC, regardless of hormone treatment. This effect of HFD consumption was detected in the medial, but not anterior or posterior, ARC. B, There was a strong trend towards an HFD-induced increase in ERα expression in the medial, but not anterior or posterior, VMH. C, D, HFD increased the number of leptin-sensitive ERα neurons in the VMH, but not in the ARC. *p < 0.05, +p = 0.054, HFD vs STND. Elizabeth P.
