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 ...
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 ...
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 ...
Insect glycerol transporters evolved by functional co-option and gene replacement
(Nature Research, 2015-07-17)
Transmembrane glycerol transport is typically facilitated by aquaglyceroporins in Prokaryota and Eukaryota. In holometabolan insects however, aquaglyceroporins are absent, yet several species possess ...
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 ...
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 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 ...
