Corticotropin-releasing hormone (CRH) is a key regulator of the mammalian stress response, mediating a wide variety of stress-associated behaviors including stress-induced inhibition of reproductive function. To investigate the potential direct action of CRH on pituitary gonadotrope function, we examined CRH receptor expression and second messenger signaling in alpha T3-1 cells, a murine gonado...
Urocortin 3 (UCN3) is strongly expressed in specific nuclei of the rodent brain, at sites distinct from those expressing urocortin 1 and urocortin 2, the other endogenous ligands of corticotropin-releasing hormone receptor type 2 (CRH-R2). To determine the physiological role of UCN3, we generated UCN3-deficient mice, in which the UCN3 open reading frame was replaced by a tau-lacZ reporter gene....
The urocortins are a family of endogenously produced peptide hormones that show great promise as potential drugs for the treatment of heart disease. They can increase contractility and cardiac output without causing changes in mean arterial blood pressure. As expected, the receptor for these peptides is present in cardiomyocytes, and they can bind and protect these cells from simulated ischemia...
On the basis of extensive basic and clinical studies, corticotropin-releasing hormone (CRH) and its related family members are considered to play a pivotal role in stress-related disorders, such as anxiety and depression. CRH is regarded as the principal mediator in the brain of the stress response, as it mediates neuroendocrine, autonomic, and behavioral responses to stressful challenges. Rece...
Because of the difficulties in developing suitable animal models, the pathogenesis of stress-induced functional gastrointestinal disorders is not well known. Here we applied the communication box technique to induce psychological stress in rats and then examined their gastrointestinal motility. We measured upper and lower gastrointestinal motility induced by acute and chronic psychological stre...
BACKGROUND Urocortin is analogous to corticotrophin-releasing factors (CRFs) and a member of the CRF family. We previously demonstrated that urocortin mRNAs were expressed in both human and rat glioma cell lines, and that some of these lines transcribed the receptors. We hypothesize that urocortin might also be expressed in a gastric cancer cell line. The aim of the present study was to clarify...
The presence of the opioids, beta-endorphin, met-enkephalin, and endomorphin, and of corticotropin-releasing factor (CRF) and the CRF family member, urocortin (Ucn), is described in cerebrospinal fluid-contacting neurons in the brain of the amphibian, Xenopus laevis.
