We investigated effects of low dose capsaicin (CAP) treatment on the different NOS isoforms in prepubertal rat ovaries. Fifteen 21-day-old female Sprague-Dawley rats were divided randomly into three groups. The first group received no treatment, the second group received 0.5 mg/kg/day CAP dissolved in the vehicle, and the third group was treated with the vehicle only. The animals were euthanized by ether inhalation after 15 days and their ovaries were excised. Ovaries were fixed in 10% neutral buffered formalin and embedded in paraffin. Sections were processed for standard immunohistochemistry using the labeled streptavidin-biotin technique for expression of nNOS, eNOS and iNOS. We demonstrated that CAP induced expression of NOS isotypes including eNOS, iNOS and nNOS in prepubertal rat ovaries. CAP may lead to release of NO either directly from nerves or indirectly by evoking release from other cells via the action of neuropeptides that are released from afferent terminals and are involved in regulating female reproductive function.eninfo:eu-repo/semantics/closedAccessBiotechnology & applied microbiologyCell biologyCapsaicineNOSiNOSnNOSOvarian folliclesFollicular developmentSmooth-muscleSubstance-pExpressionCellsLocalizationOvulationProgesteroneGonadotropinSecretionAnimaliaRattusAnimalsCapsaicinFemaleImmunohistochemistryNerve endingsNeurons, afferentNitric oxide synthaseNitric oxide synthase type INitric oxide synthase type IINitric oxide synthase type IIIOvaryRatsRats, sprague-dawleyArticle0003015300000092-s2.0-8485859187621822587321955128Biotechnology & applied microbiologyCell biologyMaturation-Promoting Factor; Oocytes; NG-nitroarginine Methyl EsterCapsaicinEndothelial nitric oxide synthaseInducible nitric oxide synthaseNeuronal nitric oxide synthaseNitric oxide synthaseNos1 protein, ratNos2 protein, ratNos3 protein, ratAnimalArticleDrug effectEnzymologyFemaleHistologyImmunohistochemistryInnervationMetabolismNerve endingOvaryRatSensory nerve cellSprague dawley rat
