Levels of Protein CoAlation Regulate Redox Signaling Events of Human Sperm Capacitation [PDF]

open access: yesAntioxidants
Infertility is a global health problem, with male factors contributing to nearly half of all cases. Up to 30% of male infertility is classified as idiopathic, in part because routine semen analysis does not assess sperm fertilizing competence ...

Novel methods to detect capacitation-related changes in spermatozoa [PDF]

open access: yesTheriogenology, 2019
Prior to interaction with the oocyte, spermatozoa must undergo capacitation, which involves a series of physio-chemical transformations that occur in the female tract.

Role of tyrosine phosphorylation in sperm capacitation / acrosome reaction

open access: yesReproductive Biology and Endocrinology, 2004
Capacitation is an important physiological pre-requisite before the sperm cell can acrosome react and fertilize the oocyte. Recent reports from several laboratories have amply documented that the protein phosphorylation especially at tyrosine residues is

Systematic mRNA interactome analysis reconceptualizes translational quiescence in bovine sperm [PDF]

open access: yesCommunications Biology
Ejaculated mammalian sperm must undergo a series of biochemical changes called capacitation to gain fertilizing competence. Mounting evidence on protein synthesis during capacitation contradicts the widely accepted dogma of translational quiescence in ...

Zinc ion flux during mammalian sperm capacitation

open access: yesNature Communications, 2018
During sperm capacitation physiological changes occur that are required for fertilization. Here, the authors describe four sperm zinc signatures during invitro capacitation that are indicative of sperm quality and capacity to fertilize.

A comparative study of capacitation-mediated changes in whole mouse sperm proteome [PDF]

open access: yesAnimal Cells and Systems
Mammalian spermatozoa acquire fertilizing ability in response to environmental factors enriched in the female reproductive tract, a process called capacitation.

Epigenetic dynamics during capacitation of naïve human pluripotent stem cells [PDF]

open access: yes, 2023
Human pluripotent stem cells (hPSCs) are of fundamental relevance in regenerative medicine. Naïve hPSCs hold promise to overcome some of the limitations of conventional (primed) hPSCs, including recurrent epigenetic anomalies. Naïve-to-primed transition (

piR-121380 Is Involved in Cryo-Capacitation and Regulates Post-Thawed Boar Sperm Quality Through Phosphorylation of ERK2 via Targeting PTPN7

open access: yesFrontiers in Cell and Developmental Biology, 2022
Cryopreservation induces capacitation-like (cryo-capacitation) changes, similar to natural capacitation, and affects the fertility potential of post-thawed sperm. The molecular mechanism of sperm cryo-capacitation during cryopreservation remains unknown.

New insights into posttranslational modifications of proteins during bull sperm capacitation

open access: yesCell Communication and Signaling, 2023
Background Due to the unique nature of spermatozoa, which are transcriptionally and translationally silent, the regulation of capacitation is based on the formation of posttranslational modifications of proteins (PTMs).
