Effects of acute stressors on the expression of oxytocin receptor mRNA in hearts of rats with different activity of HPA axis
2012
Abstract
The expression of OTR mRNA in all heart compartments of controls as well as after stress exposure in Sprague-Dawley and Lewis rats support the notion that OTR plays a regulatory role in the cardiovascular system and is also involved in the regulations in the heart after stress. The immunofluorescent observation that OTRs coexpress in areas of cell nuclei in certain heart compartments and after acute stress, compared to controls, requires further studies.
