Control of oocyte maturation
(2014-01-01)
Oocyte maturation is a complex process involving nuclear and cytoplasmic maturation. The nuclear maturation is a chromosomal segregation and the cytoplasmic maturation involves the reorganization of the cytoplasmic organelles, ...

Influence of nitric oxide during maturation on bovine oocyte meiosis and embryo development in vitro
(CSIRO PUBLISHING, 2008)
The effect of s-nitroso-N-acetyl-1,1-penicillamine (SNAP, a nitric oxide donor) during in vitro maturation (IVM) on nuclear maturation and embryo development was investigated. The effect of increasing nitric oxide (NO) ...
Regulation of meiosis initiation in the mammalian testis: novel aspects
(Elsevier, 2020-10)
Meiosis first appears at puberty in the mammalian testis, is central to spermatogenesis, and relies on androgens and retinoic acid (RA). While the role androgens play in meiosis initiation is well characterized, the mechanism ...
Distribution of constitutive heterochromatin in two species of triatomines: Triatoma lenti Sherlock and Serafim (1967) and Triatoma sherlocki Papa, Jurberg, Carcavallo, Cerqueira & Barata (2002)
(2013-01-01)
Triatoma lenti and Triatoma sherlocki are hemipterans that belong to the brasiliensis subcomplex. In triatomines, the constitutive heterochromatin pattern is species-specific and allows, in many cases, for the grouping of ...

Prorenina e receptor de (pro)renina no período peri-ovulatório bovino
(Universidade Federal de Santa MariaBRMedicina VeterináriaUFSMPrograma de Pós-Graduação em Medicina Veterinária, 2013-02-28)
The objectives of this study were: to determine the presence of prorenin and the receptor of (pro)renin [(P)RR] in cumulus cells (CC) and oocytes; evaluate the role of prorenin in the resumption of oocyte meiosis, ovulation ...
BRDT is an essential epigenetic regulator for proper chromatin organization, silencing of sex chromosomes and crossover formation in male meiosis
(Public Library Science, 2018)
The double bromodomain and extra-terminal domain (BET) proteins are critical epigenetic
readers that bind to acetylated histones in chromatin and regulate transcriptional activity
and modulate changes in chromatin structure ...
