Aquaporin splice variation differentially modulates channel function during marine teleost egg hydration
(Public Library of Science, 2023-11-27)
Aquaporin-mediated oocyte hydration is a developmentally regulated adaptive mechanism that co-occurs with meiosis resumption in marine teleosts. It provides the early embryos with vital water until ...
Functional Evolution of Clustered Aquaporin Genes Reveals Insights into the Oceanic Success of Teleost Eggs
(Oxford University Press, 2023-03-22)
Aquaporin-mediated oocyte hydration is considered important for the evolution of pelagic eggs and the radiative success of marine teleosts. However, the molecular regulatory mechanisms controlling this ...
Neurohypophysial and paracrine vasopressinergic signaling regulates aquaporin trafficking to hydrate marine teleost oocytes
(Frontiers, 2023-08-11)
The dual aquaporin (Aqp1ab1/Aqp1ab2)-mediated hydration of marine teleost eggs, which occurs during oocyte meiosis resumption (maturation), is considered a key adaptation underpinning their evolutionary ...
Unravelling the complex duplication history of deuterostome glycerol transporters
(MDPI, 2020-07-10)
Transmembrane glycerol transport is an ancient biophysical property that evolved in selected subfamilies of water channel (aquaporin) proteins. Here, we conducted broad level genome (>550) and transcriptome ...
Role of Ion Channels in the Maintenance of Sperm Motility and Swimming Behavior in a Marine Teleost
(MDPI, 2022-10-11)
In oviparous marine fishes, the hyperosmotic induction of sperm motility in seawater (SW) is well established, however, the potential function of ion channels in the maintenance of post activated ...
Gonadotropin induction of spermiation in Senegalese sole: Effect of temperature and stripping time
(Elsevier, 2021-12-21)
Treatments with homologous recombinant follicle-stimulating and luteinizing hormones (rFsh and rLh, respectively) are known to enhance spermatogenesis and sperm production in sole, but the response can ...
Kisspeptin influences the reproductive axis and circulating levels of microRNAs in Senegalese sole
(MDPI, 2020-11-28)
Kisspeptin regulates puberty and reproduction onset, acting upstream of the brain–pituitary–gonad (HPG) axis. This study aimed to test a kisspeptin-based hormonal therapy on cultured Senegalese sole ...
Providing recombinant gonadotropin-based therapies that induce oogenesis from previtellogenic oocytes to produce viable larvae in a teleost, the flathead grey mullet (Mugil cephalus)
(Elsevier, 2021-01-27)
Under intensive captive conditions, wild-caught flathead grey mullet (Mugil cephalus) females remained arrested in previtellogenic stages of gonadal development and no sperm could be obtained from males. ...
