Oxtr expression in the male brain.
(A) RNAscope revealed Oxtr-positive transcripts in the epididymis, but not in the liver (positive and negative controls, respectively). Also shown are representative micrographs of the posteromedial part of the amygdalohippocampal area (AHiPM) of the hypothalamus, pyramidal cell layer (Py) of the hippocampus, and the third ventricle (3V) of the ventricular regions. Scale bar: 50 µm. (B) Oxtr transcript density in the brain regions detected by RNAscope. (C) Oxtr transcript density in nuclei, sub-nuclei, and regions of the ventricular system, hypothalamus, olfactory bulb, hippocampus, cerebral cortex, medulla, midbrain and pons, forebrain, thalamus, and cerebellum.

Oxtr expression in the male brain.
Oxtr transcript number in brain regions and in nuclei, sub-nuclei, and regions of the hypothalamus, cerebral cortex, hippocampus, olfactory bulb, midbrain and pons, thalamus, medulla, forebrain, cerebellum, and ventricular system detected by RNAscope. Also shown are representative RNAscope images of several hypothalamic regions, including lateral hypothalamus (LH), tuber cinereum (TC), anterior part of the basolateral amygdaloid nucleus (BLA), dorsomedial hypothalamus (DM), and central part of ventromedial hypothalamic nucleus (VMHC). Note that LH and DM send SNS outflow to both bone and fat tissue. Scale bar: 20 µm.

Sex differences in Oxt expression in the mouse brain.
(A) The neurohypophysial hormone OXT is synthesized by magnocellular neurons primarily located in the PVH and SON hypothalamic nuclei. The magnocellular neurons send extended axonal projections into the neurohypophysis where OXT is released into the circulation in response to physiological demands. Therefore, PVH and SON served as positive controls for OXT expression in the brain. MPA: medial preoptic area; LPO: lateral preoptic area of the forebrain. Scale bar: 50 µm. (B) Sex differences in the numbers of Oxt-expressing neurons in nuclei, sub-nuclei, and regions of the hypothalamus and forebrain detected by RNAscope. (C) Total numbers of Oxt-expressing neurons in nuclei, sub-nuclei, and regions of the hypothalamus and forebrain of male and female mice. (D) Oxt transcript density in nuclei, sub-nuclei, and regions of the hypothalamus and forebrain of male and female mice. N = 3, values are shown as means ± SE. Student’s t-test.
