    Notes: Summary The presence of the CRF-containing neurons in the hypothalamus was investigated in four different species (cats, dogs, pigs, and monkeys) by the peroxidase-antiperoxidase technique using specific anti-serum to CRF. In all animals examined, CRF-containing perikarya were found mainly in the paraventricular and supraoptic nuclei, and a small number of the immunoreactive cells were observed in the accessory supraoptic nucleus and the lateral hypothalamic area. The size of the CRF-containing perikarya ranged from 20–35 μm in diameter. These findings suggest that the magnocellular paraventricular and supraoptic nuclei are the center not only of the classical neurosecretory system for the production of the posterior lobe hormones, but also that of the CRF neuronal system.

    Notes: Abstract The Borg (binder of Rho GTPases) family proteins interact with CDC42 and TC10 in a guanosine triphosphate (GTP)-dependent manner. We have isolated a full-length cDNA of the mouse Borg4 gene, which is a member of this family. Sequence analysis revealed that this gene encoded a putative 349-amino acid protein. By reverse transcription — coupled polymerase chain reaction (RT-PCR) analysis, we observed that Borg4 was expressed ubiquitously in adult tissues. Additionally, we determined the entire cDNA sequence of the putative human Borg4 orthologue. By fluorescence in situ hybridization, mouse Borg4 and the putative human orthologue have been assigned to mouse chromosome 11E and human chromosome 17q24–25, which has been described as syntenic to the mouse region.

    Notes: Summary A specific rabbit anti-CRF serum and the immunoperoxidase technique were used to show that CRF-containing neurons are mainly distributed in the paraventricular and supraoptic nuclei of the rat hypothalamus. In addition, immunoreactive neurons are scattered in other hypothalamic regions. These neurons are 20–30 μm in diameter. From the present and previous investigations it may be concluded that the hypothalamic magnocellular nuclei, i.e., paraventricular and supraoptic, and other hypothalamic accessory nuclei, are the producing sites not only for vasopressin and oxytocin, but also for corticotropin-releasing factor.
