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 ...
A multiplier peroxiporin signal transduction pathway powers piscine spermatozoa
(National Academy of Sciences, 2021-03-09)
The primary task of a spermatozoon is to deliver its nuclear payload to the egg to form the next-generation zygote. With polyandry repeatedly evolving in the animal kingdom, however, sperm competition ...
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 ...
Lineage-level divergence of copepod glycerol transporters and the emergence of isoform-specific trafficking regulation
(Nature Research, 2021-05-31)
Transmembrane conductance of small uncharged solutes such as glycerol typically occurs through aquaglyceroporins (Glps), which are commonly encoded by multiple genes in metazoan organisms. To date, ...
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 ...
The cellular localization and redistribution of multiple aquaporin paralogs in the spermatic duct epithelium of a maturing marine teleost
(Wiley, 2018-05-27)
Aquaporin‐mediated fluid transport in the mammalian efferent duct and epididymis is believed to play a role in sperm maturation and concentration. In fish, such as the marine teleost gilthead seabream ...
Toward developing recombinant gonadotropin-based hormone therapies for increasing fertility in the flatfish Senegalese sole
(Public Library of Science, 2017-03-22)
Captive flatfishes, such as the Senegalese sole, typically produce very low volumes of sperm. This situation is particularly prevalent in the first generation (F1) of reared sole males, which limits the ...
Seasonal-and dose-dependent effects of recombinant gonadotropins on sperm production and quality in the flatfish Solea senegalensis
(Elsevier, 2018-07-02)
Consecutive treatments with recombinant follicle-stimulating and luteinizing hormones (rFsh and rLh, respectively) stimulate spermatogenesis and potentiate sperm production in pubescent specimens of the ...
