Potential Role of Acetylation on Equine Sperm Capacitation

, 2021
A series of biochemical and physical modifications in the sperm during the transport in the female reproductive tract that make the sperm capable of fertilization are called capacitation.

Time to revise: impact of methodology on boar sperm capacitation in vitro via phosphotyrosine patterns

BMC Veterinary Research
Capacitation is a crucial sperm maturation process occurring in vivo in the female reproductive tract, enabling spermatozoa to fertilize the oocyte. In vitro, capacitation can be induced using defined capacitation media (CM), with further assessment of ...

High throughput small RNA and transcriptome sequencing reveal capacitation-related microRNAs and mRNA in boar sperm

BMC Genomics, 2018
Background Capacitation, a prerequisite for oocyte fertilization, is a complex process involving series of structural and functional changes in sperms such as membrane modifications, modulation of enzyme activities, and protein phosphorylation.

Exogenous Albumin Is Crucial for Pig Sperm to Elicit In Vitro Capacitation Whereas Bicarbonate Only Modulates Its Efficiency

Biology, 2021
This work sought to address whether the presence of exogenous bicarbonate is required for pig sperm to elicit in vitro capacitation and further progesterone-induced acrosome exocytosis. For this purpose, sperm were either incubated in a standard in vitro

Dissociation between AKAP3 and PKARII promotes AKAP3 degradation in sperm capacitation. [PDF]

PLoS ONE, 2013
Ejaculated spermatozoa must undergo a series of biochemical modifications called capacitation, prior to fertilization. Protein-kinase A (PKA) mediates sperm capacitation, although its regulation is not fully understood.

Membrane Potential Assessment by Fluorimetry as a Predictor Tool of Human Sperm Fertilizing Capacity

Frontiers in Cell and Developmental Biology, 2020
Mammalian sperm acquire the ability to fertilize eggs by undergoing a process known as capacitation. Capacitation is triggered as the sperm travels through the female reproductive tract.

Tyrosine Phosphorylation Events in Mouse Sperm Capacitation

, 2009
Mammalian sperm are not able to fertilize immediately upon ejaculation; they become fertilization-competent after undergoing changes in the female reproductive tract collectively termed capacitation.

The ABCA1 blocking agent probucol decreases capacitation in ejaculated dog spermatozoa

Acta Veterinaria Scandinavica, 2020
Background The ATP binding cassette (ABC) transporters participate in the cholesterol and phospholipid transport within and through cell membranes of many cells including spermatozoa. Cholesterol efflux is important for capacitation of spermatozoa. ABCA1

Quantitative phosphoproteomics analyses reveal the regulatory mechanisms related to frozen-thawed sperm capacitation and acrosome reaction in yak (Bos grunniens)

Frontiers in Physiology, 2022
Mammalian spermatozoa are not mature after ejaculation and must undergo additional functional and structural changes within female reproductive tracts to achieve subsequent fertilization, including both capacitation and acrosome reaction (AR), which are ...
