Beschreibung:
Environmental exposures affect gamete function and fertility, but the mechanisms are poorly understood. Here, we show that pheromones sensed by ciliated neurons in the Caenorhabditis elegans nose alter the lipid microenvironment within the oviduct, thereby affecting sperm motility. In favorable environments, pheromone-responsive sensory neurons secrete a transforming growth factor-beta ligand called DAF-7, which acts as a neuroendocrine factor that stimulates prostaglandin-endoperoxide synthase [cyclooxygenase (Cox)]-independent prostaglandin synthesis in the ovary. Oocytes secrete F-class prostaglandins that guide sperm toward them. These prostaglandins are also synthesized in Cox knockout mice, raising the possibility that similar mechanisms exist in other animals. Our data indicate that environmental cues perceived by the female nervous system affect sperm function.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4094289/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉 〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4094289/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉McKnight, Katherine -- Hoang, Hieu D -- Prasain, Jeevan K -- Brown, Naoko -- Vibbert, Jack -- Hollister, Kyle A -- Moore, Ray -- Ragains, Justin R -- Reese, Jeff -- Miller, Michael A -- GM085105/GM/NIGMS NIH HHS/ -- HL096967/HL/NHLBI NIH HHS/ -- HL109199/HL/NHLBI NIH HHS/ -- HL110950/HL/NHLBI NIH HHS/ -- HL114439/HL/NHLBI NIH HHS/ -- P30 AR050948/AR/NIAMS NIH HHS/ -- P30 DK079337/DK/NIDDK NIH HHS/ -- P40 OD010440/OD/NIH HHS/ -- R01 GM085105/GM/NIGMS NIH HHS/ -- R01 HL096967/HL/NHLBI NIH HHS/ -- R01 HL109199/HL/NHLBI NIH HHS/ -- S10 RR19261/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 2014 May 16;344(6185):754-7. doi: 10.1126/science.1250598.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Reproductive Endocrinology and Infertility, Department of Obstetrics and Gynecology, University of Alabama at Birmingham, Birmingham, AL 35294, USA. ; Department of Cell, Developmental and Integrative Biology, University of Alabama at Birmingham, Birmingham, AL 35294, USA. ; Department of Pharmacology and Toxicology, University of Alabama at Birmingham, Birmingham, AL 35294, USA. ; Department of Pediatrics, Vanderbilt University, Nashville, TN 37232, USA. ; Department of Chemistry, Louisiana State University, Baton Rouge, LA 70803, USA. ; Department of Pediatrics, Vanderbilt University, Nashville, TN 37232, USA.
