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.

TECTB Variants Reveal Tectorial Membrane Vulnerability in Dominant Non‐Syndromic Hearing Loss

Advanced Science, EarlyView.
TECTB is a non‐collagenous protein of the tectorial membrane – an extracellular matrix of the cochlea. This study identifies dominant missense variants in TECTB linked to human hereditary deafness in two unrelated families. Genetically engineered mice homozygous for one of the variants are profoundly deaf, whereas heterozygous mice have normal hearing ...

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.

Characterization of human zona pellucida glycoproteins [PDF]

Molecular Human Reproduction, 1999
The human egg may only be fertilized by one spermatozoon to prevent polyploidy. In most mammals, the primary block to polyspermy occurs at the zona pellucida (ZP). Little is known of the human ZP and the changes occurring following fertilization to prevent polyploidy. Using antibodies directed against synthetic peptides predicted from the human ZP2 and

Follicle Stimulating Hormone in Cattle Breeding: Fundamentals, Innovations, and Scope

Animal Research and One Health, EarlyView.
FSH is crucial in cattle reproduction, with exogenous administration enhancing breeding and embryo production. Recombinant FSH offers advantages over pituitary‐extracted variants, including fewer injections, reduced stress, and safer production. These innovations improve breeding efficiency, optimize reproductive outcomes, and contribute to sustainable

Impact of donor mare and stallion identity on the likelihood of pregnancy after transfer of in vitro produced embryos

Equine Veterinary Journal, EarlyView.
Abstract Background The success of in vitro embryo production (IVEP) is influenced by donor mare and stallion. Objectives To determine whether donor mare and stallion influence the pregnancy rate after transfer of in vitro produced (IVP) blastocysts and to identify factors influencing the likelihood of obtaining one or more pregnancies from a single ...

Protease activity involvement in the passage of mammalian sperm through the zona pellucida

Biological Research, 2011
The interaction between acrosome-reacted sperm and zona pellucida proteins is not yet fully understood. Serine protease acrosin and its zymogen proacrosin have been proposed to fulfill this function due to their capacity to bind zona pellucida ...

Cupulin is a zona pellucida-like domain protein and major component of the cupula from the inner ear. [PDF]

PLoS ONE, 2014
The extracellular membranes of the inner ear are essential constituents to maintain sensory functions, the cupula for sensing torsional movements of the head, the otoconial membrane for sensing linear movements and accelerations like gravity, and the ...

Assessing Metabolic and Reproductive Consequences of Prenatal Paracetamol Exposure in Female CD1 Mice

Journal of Applied Toxicology, EarlyView.
ABSTRACT Paracetamol is a widely used analgesic during pregnancy; however, emerging evidence suggests it may act as an endocrine/metabolism disrupting compound. Using an F1 female CD1 mouse model, this study scrutinized the long‐term metabolic and reproductive consequences linked to intrauterine paracetamol exposure.
