Ovarian steroids regulate tachykinin and tachykinin receptor gene expression in the mouse uterus
BACKGROUND In the mouse uterus, pregnancy is accompanied by changes in tachykinin and tachykinin receptor gene expression and in the uterotonic effects of endogenous tachykinins. In this study we have investigated whether changes in tachykinin expression and responses are a result of changes in ovarian steroid levels. METHODS We quantified the mRNAs of tachykinins and tachykinin receptors in ...
متن کاملTachykinin receptor expression and function in human esophageal smooth muscle.
Tachykinins are present in enteric nerves of the gastrointestinal tract and cause contraction of esophageal smooth muscle; however, the mechanisms involved are not understood. Our aim was to characterize tachykinin signaling in human esophageal smooth muscle. We investigated functional effects of tachykinins on human esophageal smooth muscle using tension recordings and isolated cells, receptor...
متن کاملEstradiol differentially regulates c-Fos after focal cerebral ischemia.
Estrogen replacement therapy enhances mood, delays cognitive decline, and reduces the risk of neurodegeneration. Our laboratory has shown previously that pretreatment with low physiological levels of estradiol protects against middle cerebral artery occlusion (MCAO)-induced brain injury during late phases of neuronal cell death. Immediate early genes (IEGs) are induced by various forms of brain...
متن کاملNon-neuronal mammalian tachykinin expression.
Mammalian tachykinins are traditionally viewed as neuropeptides. This review describes the mammalian tachykinins and evidence for expression of these peptides by non-neuronal cells. Tachykinin expression is defined as evidence for gene transcription, peptide production, or peptide secretion. Since the functions of mammalian tachykinins have been amply reviewed, the biological roles of these pep...
متن کاملHyperexcitability-associated rapid plasticity after a focal cerebral ischemia.
BACKGROUND AND PURPOSE This article addresses how neuroplastic changes are initiated after an ischemic stroke. METHODS A focal cerebral ischemia was photochemically induced on the primary somatosensory cortex of rats, and in vivo electrophysiological recordings were performed on the peri-infarct cortex before and from 1 to 6 hours after the infarction. RESULTS Paired-pulse analysis of evoke...
