Nejire/dCBP-mediated control of H3 acetylation and transcriptional regulation by testis-specific Plus3 domain proteins during Drosophila spermatogenesis [PDF]

open access: yes, 2018
Spermatogenesis describes the development from germ line stem cells to highly specialized sperm. Drosophila melanogaster spermatogenesis is a good model system for chromatin remodelling processes as many of these processes are similar in mammals and in ...

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.

PENGARUH PEMBERIAN RANITIDINE TERHADAP SPERMATOGENESIS TIKUS Wistar DENGAN INTOKSIKASI METANOL AKUT DILIHAT SECARA HISTOPATOLOGIS

open access: yesJurnal Kedokteran Diponegoro, 2017
Latar belakang: Metanol memiliki efek toksik melalui metabolitnya yaitu asam format yang mengakibatkan gangguan spermatogenesis. Ranitidine mempunyai enzim yang dapat menghambat terbentuknya metabolit asam format sehingga diharapkan akan mengurangi efek ...

Methylation of the Gpat2 promoter regulates transient expression during mouse spermatogenesis [PDF]

open access: yes, 2015
Spermatogenesis is a highly regulated process that involves both mitotic and meiotic divisions, as well as cellular differentiation to yield mature spermatozoa from undifferentiated germinal stem cells.

Transcriptome profiling of laser-captured germ cells and functional characterization of zbtb40 during 17alpha-methyltestosterone-induced spermatogenesis in orange-spotted grouper (Epinephelus coioides)

open access: yesBMC Genomics, 2020
Background Spermatogenesis is an intricate process regulated by a finely organized network. The orange-spotted grouper (Epinephelus coioides) is a protogynous hermaphroditic fish, but the regulatory mechanism of its spermatogenesis is not well-understood.

Multipathway synergy promotes testicular transition from growth to spermatogenesis in early-puberty goats

open access: yesBMC Genomics, 2020
Background The microscopic process of postnatal testicular development in early-puberty animals is poorly understood. Therefore, in this study, 21 male Yiling goats with average ages of 0, 30, 60, 90, 120, 150 and 180 days old (each age group comprised ...

Pathological and molecular examinations of postmortem testis biopsies reveal SARS-CoV-2 infection in the testis and spermatogenesis damage in COVID-19 patients

open access: yesCellular & Molecular Immunology, 2020
In late December 2019, the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which causes coronavirus disease 2019 (COVID-19), was identi fi ed in Wuhan, China, and the ensuing pandemic has led to more than 50 million infected ...

Developmental changes in the histological structure of the testes, and testosterone profiles in male guinea fowls (Numida meleagris) [PDF]

open access: yes, 2017
Owing to the paucity of information on the reproductive biology of guinea fowls, a study involving a total of 66 males was conducted, and documented the developmental changes in histological structure of the testes of guinea cocks from hatching until ...

Gene expression profiles of mouse spermatogenesis during recovery from irradiation

open access: yesReproductive Biology and Endocrinology, 2009
Background Irradiation or chemotherapy that suspend normal spermatogenesis is commonly used to treat various cancers. Fortunately, spermatogenesis in many cases can be restored after such treatments but knowledge is limited about the re-initiation ...

Follistatin-like 3 (FSTL3) mediated silencing of transforming growth factor (TGF ) signaling is essential for testicular aging and regulating testis size [PDF]

open access: yes, 2013
Follistatin-like 3 (FSTL3) is a glycoprotein that binds and inhibits the action of TGFβ ligands such as activin. The roles played by FSTL3 and activin signaling in organ development and homeostasis are not fully understood.
