Fig 6. Melanocortin 4 receptor (MC4R) expression is reduced in DMN of outbred DIO-D Sprague Dawley rats.

(A) Representative darkfield photomicrographs showing in situ hybridization of MC4R mRNA gene expression in the DMN (outlined region) from DR (left) and DIO-D (right) outbred rats. Scale: 100 μm. 3V, third ventricle. (B) In situ hybridization for MC4R resulted in fewer silver grains over individual neurons in DMN, but not PVN or ARC of DIO-D vs. DR rats. Data were obtained from 9 DR and 5 DIO rats. Numbers of cells studied per animal: PVN—n = 113 ± 15 (DR), n = 97 ± 15 (DIO), p = 0.5; ARC—n = 61 ± 4 (DR), n = 60 ± 7 (DIO), p = 0.8; DMH—n = 127 ± 13 (DR), 92 ± 14 (DIO), p = 0.12. ** p < 0.01.
