Successful capacitation and homologous fertilization in vitro in Calomys musculinus and Calomys laucha (Rodentia, Sigmodontinae)
(Portland Press, 2000-02)
Small South American rodents of the genus Calomys have been used extensively for virology and ecological research. Previous studies have demonstrated that Calomys musculinus and Calomys laucha have a relatively short ...
Impaired sperm fertilizing ability in mice lacking Cysteine-RIch Secretory Protein 1 (CRISP1)
(Elsevier, 2008-12)
Mammalian fertilization is a complex multi-step process mediated by different molecules present on both gametes. Epididymal protein CRISP1, a member of the Cysteine-RIch Secretory Protein (CRISP) family, was identified by ...
Sperm morphology of two marine neogastropods from the southwestern Atlantic Ocean (Caenogastropoda: Volutidae and Olividae)
(Bailey-Matthews Shell Museum, 2009-10)
The testes of Caenogastropoda typically produce two types of spermatozoa, euspermatozoa and paraspermatozoa. The structures of both morphological forms of sperm contribute to our understanding of reproductive biology, and ...
Molecular mechanisms involved in gamete interaction: evidence for the participation of cysteine-rich secretory proteins (CRISP) in sperm-egg fusion
(Nottingham University Press, 2007)
Epididymal protein DE and testicular protein Tpx-1 are two cysteine-rich secretory proteins also known as CRISP-1 and CRISP-2, respectively. DE/CRISP-1 is localised on the equatorial segment of acrosome-reacted sperm and ...
Cysteine-rich secretory proteins (CRISP) proteins are key players for mammalian fertilization and fertility
(Frontiers Media, 2021)
Mammalian fertilization is a complex process involving a series of successive sperm-egg interaction steps mediated by different molecules and mechanisms. Studies carried out during the past 30 years, using a group of ...
Evidence for the involvement of Proline-rich Tyrosine Kinase 2 (PYK2) in tyrosine phosphorylation downstream of PKA activation during human sperm capacitation
(Oxford University Press, 2014-09-01)
Sperm capacitation involves an increase in intracellular Ca(2+) concentration as well as in protein kinase A (PKA)-dependent protein tyrosine (Tyr) phosphorylation. Interestingly, in humans, a decrease in extracellular ...
Evidence for the involvement of testicular protein CRISP2 in mouse sperm-egg fusion
(Society for the Study of Reproduction, 2007)
Porcine oocyte preincubation in oviductal fluid flush before in vitro fertilization in the presence of oviductal epithelial cells improves monospermic zygote production
(Cambridge University Press, 2021-02)
The present study was designed to evaluate the effect of the combination of oviduct fluid flush (OFF) and oviduct epithelial cells (OEC) in modulating the incidence of polyspermy in pigs. Therefore, for in vitro fertilization ...
