Chromodomain Helicase DNA–Binding Proteins and Spermatogenesis: Current Advances

open access: yesAndrology, EarlyView.
ABSTRACT Background Male infertility is a prevalent clinical condition, with approximately one‐third of cases classified as idiopathic, frequently stemming from impaired spermatogenesis because of dysregulated gene expression. Chromodomain helicase DNA‐binding (CHD) proteins are central chromatin remodelers that orchestrate this epigenetic regulation ...

Non-random chromosome positioning in mammalian sperm nuclei, with migration of the sex chromosomes during late spermatogenesis [PDF]

open access: yes, 2005
Chromosomes are highly organized and compartmentalized in cell nuclei. The analysis of their position is a powerful way to monitor genome organization in different cell types and states.

SOX30 Governs Synaptonemal Complex Assembly and Homologous Recombination in Male Meiosis

open access: yesCell Proliferation, EarlyView.
The transcription factor SOX30 directly binds promoter regions of SYCE1 and SYCE2 to mediate their transcriptional activation, thereby enabling proper assembly of central elements within the synaptonemal complex. Structural destabilisation of the synaptonemal complex in Sox30 KK spermatocytes triggers synaptic discontinuity, impairs homologous ...

Evolutionary conservation of lampbrush-like loops in drosophilids

open access: yesBMC Cell Biology, 2007
Background Loopin-1 is an abundant, male germ line specific protein of Drosophila melanogaster. The polyclonal antibody T53-F1 specifically recognizes Loopin-1 and enables its visualization on the Y-chromosome lampbrush-like loop named kl-3 during ...

Histomorphometrical study of gonads in the endemic cyprinid fish, Cyprinion tenuiradius Heckel, 1847 (Cypriniformes: Cyprinidae) [PDF]

open access: yes, 2017
To describe the morphological and histological changes during the annual reproductive cycle of the gonads of Cyprinion tenuiradius, a total of 341 specimens (102 female and 235 male specimens) were collected monthly from the Rudbal River (in the Qarah ...

Spermatogenesis and sertoli cell activity in mice lacking Sertoli cell receptors for follicle stimulating hormone and androgen [PDF]

open access: yes, 2008
Spermatogenesis in the adult male depends on the action of FSH and androgen. Ablation of either hormone has deleterious effects on Sertoli cell function and the progression of germ cells through spermatogenesis.

Plasticity in the reproductive biology of Yellowstone cutthroat trout Oncorhynchus virginalis bouvieri in Yellowstone Lake following lake trout Salvelinus namaycush invasion

open access: yesJournal of Fish Biology, EarlyView.
Abstract Yellowstone cutthroat trout Oncorhynchus virginalis bouvieri in Yellowstone Lake are the focus of intensive conservation efforts due to the threat of predation by invasive lake trout Salvelinus namaycush. Suppression gillnetting has reduced the abundance of predatory lake trout, and the Yellowstone cutthroat trout population is recovering ...

Reproductive behaviour of the ocean triggerfish Canthidermis sufflamen (Tetraodontiformes: Balistidae) in the shallow waters of the marine‐protected area of El Hierro Island (Canary Islands)

open access: yesJournal of Fish Biology, EarlyView.
Abstract The abundance of Canthidermis sufflamen has increased worldwide, including around the Canary Islands, due to global ocean warming. The reproductive behaviour of this species was studied within a marine‐protected area (MPA) and its adjacent areas off the island of El Hierro (Canary Islands).
