Structural analysis of peptide-analogues of human Zona Pellucida ZP1 protein with amyloidogenic properties: insights into mammalian Zona Pellucida formation. [PDF]

PLoS ONE, 2013
Zona pellucida (ZP) is an extracellular matrix surrounding and protecting mammalian and fish oocytes, which is responsible for sperm binding. Mammalian ZP consists of three to four glycoproteins, called ZP1, ZP2, ZP3, ZP4.

Antigenicity of the Human Zona Pellucida [PDF]

Biology of Reproduction, 1977
Antigenicity of the human zona pellucida was investigated. Rabbit antiserum against saline homogenates of human ovary yielded a minimum of 9 precipitin bands when reacted against human ovary in agar-gel double diffusion analyses. The same antiserum also cross-reacted in varying degrees when tested against 21 other human tissues and fluids. Anti-human-

Sperm morphology and DNA fragmentation after zona pellucida selection

Reproduction and Fertility, 2021
Sperm DNA fragmentation (SDF) and sperm morphological defects can negatively affect ART outcomes. Consequently, there is a need for additional semen processing technique that accounts for sperm DNA status and morphology prior to ICSI.

Vitrification of human immature oocytes before and after in vitro maturation: a review [PDF]

, 2017
The use of immature oocytes subjected to in vitro maturation (IVM) opens interesting perspectives for fertility preservation where ovarian reserves are damaged by pathologies or therapies, as in PCO/PCOS and cancer patients. Human oocyte cryopreservation

Ovarian Matrisome Dynamics and αvβ3‐Mediated Regulation in Early Follicular Development

Advanced Science, EarlyView.
The matrisome undergoes dynamic remodeling during early follicular development. Integrin αvβ3 mediates matrisome signals, regulating primordial follicle activation/atresia and secondary follicle growth via Hippo/mTOR pathways, with conserved roles in human ovaries, offering therapeutic targets for ovarian disorders.

CaMKIIalpha interacts with multi-PDZ domain protein MUPP1 in spermatozoa and prevents spontaneous acrosomal exocytosis [PDF]

, 2009
The success of acrosomal exocytosis, a complex process with a variety of inter-related steps, relies on the coordinated interaction of participating signaling molecules.

Cryopreservation of equine oocytes: looking into the crystal ball [PDF]

, 2020
In vitro embryo production has evolved rapidly in the horse over the past decade, but blastocyst rates from vitrified equine oocytes remain quite poor and further research is needed to warrant application.

Paternal Circadian Disruption Impairs Offspring Cognition via Sperm microRNAs

Advanced Science, EarlyView.
Paternal circadian disruption remodels the sperm small RNA payload, elevating miR‐92a‐3p/miR‐25‐3p levels and perturbing early embryonic gene regulatory programs. Microinjection experiments and single‐embryo transcriptomics reveal sex‐specific developmental vulnerabilities, ultimately impairing offspring hippocampal synaptic plasticity and cognition ...

Demonstration of ovarian and brain tissue interactions as a result of stimulation of oogenesis in Migraine Modeled rats.

Revista Científica
Migraine, is a primary neurological disease. Although there is no gender difference in the prepubertal period, migraine is more common in adult women than in adult men. This situation decreases with menopause, but still its dominance in women continues.

Expression of genes encoding zona pellucida glycoproteins and cortical granule distribution in porcine oocytes isolated from small and medium follicles in relation to puberty status of donors

Czech Journal of Animal Science, 2017
The zona pellucida proteins belong to a group of proteins that regulate the processes of gamete recognition, interaction, and fusion, since they are recognized as primary and secondary sperm receptors.
