We used triple labeling immunohistochemistry to show that neurons in the hypothalamus and amygdala of diazepam-treated BPH/2 mice that had been activated by restraint stress (contained c-Fos protein in the nucleus) also contain GABAAR. By contrast, neurons activated by restraint stress in the same regions of diazepam-treated BPN/3 mice did not label for GABAAR. Presumably this is because they were inhibited by the diazepam treatment unlike those of BPH/2 mice, which did not respond to diazepam. The gene discussed is FOS; the disease is benign prostatic hyperplasia.
