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. ...
The pH sensitivity of Aqp0 channels in tetraploid and diploid teleosts
(Wiley Open Access, 2015-02-09)
Water homeostasis and the structural integrity of the vertebrate lens is partially mediated by AQP0
channels. Emerging evidence indicates that external pH may be involved in channel gating. Here we ...
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 ...
Developmental RNA-Seq transcriptomics of haploid germ cells and spermatozoa uncovers novel pathways associated with teleost spermiogenesis
(Nature Research, 2022-08-19)
In non-mammalian vertebrates, the molecular mechanisms involved in the transformation of haploid germ cells (HGCs) into spermatozoa (spermiogenesis) are largely unknown. Here, we investigated this process ...
The Lineage-Specific Evolution of Aquaporin Gene Clusters Facilitated Tetrapod Terrestrial Adaptation
(Public Library of Science, 2014-11-26)
A major physiological barrier for aquatic organisms adapting to terrestrial life is dessication in the aerial environment. This barrier was nevertheless overcome by the Devonian ancestors of extant ...
The vertebrate Aqp14 water channel is a neuropeptide-regulated polytransporter
(Springer Nature, 2019-12-11)
Water channels (aquaporins) were originally discovered in mammals with fourteen subfamilies now identified (AQP0-13). Here we show that a functional Aqp14 subfamily phylogenetically related to AQP4-type ...
Auto-Adhesion Potential of Extraocular Aqp0 during Teleost Development
(Public Library of Science, 2016-05-06)
AQP0 water channels are the most abundant proteins expressed in the mammalian lens fiber membranes where they are essential for lens development and transparency. Unlike other aquaporin paralogs, mammalian ...
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 ...
Mitochondrial aquaporin-8-mediated hydrogen peroxide transport is essential for teleost spermatozoon motility
(Nature Research, 2015-01-14)
Reactive oxygen species (ROS), particularly hydrogen peroxide (H2O2), cause oxidative cell damage and inhibit sperm function. In most oviparous fishes that spawn in seawater (SW), spermatozoa may be ...
Role of aquaporins during teleost gametogenesis and early embryogenesis
(Frontiers Media, 2011-09-30)
Aquaporins are believed to be involved in homeosmotic mechanisms of marine teleosts.
Increasing data suggest that these molecular water channels play critical roles associated
with the adaptation of ...
