Molecular cloning, spatial and temporal expression analysis of CatSper genes in the Chinese Meishan pigs

Reproductive Biology and Endocrinology, 2011
Background Sperm ion channel proteins (CatSpers) are essential for sperm hyperactivated motility, and then penetration through the zona pellucida. The CatSper class of proteins have well been characterized in the mouse and human.

Homozygous in-frame deletion inCATSPEREin a man producing spermatozoa with loss of CatSper function and compromised fertilizing capacity

Human Reproduction, 2018
Does a man (patient 1) with a previously described deficiency in principle cation channel of sperm (CatSper) function have a mutation in the CatSper-epsilon (CATSPERE) and/or CatSper-zeta (CATSPERZ) gene?Patient 1 has a homozygous in-frame 6-bp deletion in exon 18 (c.2393_2398delCTATGG, rs761237686) of CATSPERE.CatSper is the principal calcium channel ...

Increased mitochondrial activity upon CatSper channel activation is required for mouse sperm capacitation

Redox Biology, 2021
To fertilize an oocyte, sperm must undergo several biochemical and functional changes known as capacitation. A key event in capacitation is calcium influx through the cation channel of sperm (CatSper).

Viscoelasticity‐Induced Controllable Periodic Meso‐Textures of Liquid Crystal Polymers in Additive Manufacturing

Advanced Functional Materials, Volume 36, Issue 32, 20 April 2026.
Viscoelasticity‐driven instabilities are harnessed to create tunable, periodic textures in 3D‐printed liquid crystalline polymers. This study illustrates how processing parameters control these spontaneous meso‐scale patterns. These unique structural architectures unlock new possibilities for functional devices, ranging from photonic components to ...

Molecular Mechanism Underlying the Action of Zona-pellucida Glycoproteins on Mouse Sperm

Frontiers in Cell and Developmental Biology, 2020
Mammalian oocytes are enveloped by the zona pellucida (ZP), an extracellular matrix of glycoproteins. In sperm, stimulation with ZP proteins evokes a rapid Ca2+ influx via the sperm-specific, pH-sensitive Ca2+ channel CatSper.

Transmission Ratio Distortion Detection Using Microsatellite and Single Nucleotide Polymorphism Markers in Hanwoo of Gyeongnam Province

Animal Genetics, Volume 57, Issue 2, April 2026.
ABSTRACT This study aimed to identify and compare transmission ratio distortion (TRD) patterns using microsatellite (MS) markers and single nucleotide polymorphism (SNP) markers in a Hanwoo population from Gyeongnam Province. The objective was to construct parent‐offspring trios and investigate TRD patterns that may influence mortality and economic ...

The Oxytocin Receptor in Spermatozoa May Originate From Both Spermatogenesis and Epididymal Maturation, and Regulates Capacitation

Andrology, Volume 14, Issue 3, Page 747-765, March 2026.
Abstract Background The oxytocin receptor (OR) is a G‐protein‐coupled receptor recently identified in human spermatozoa, whose origin and role in sperm physiology remain unknown. Objectives In this study, using the pig as a model, we examine the presence of the OR in ejaculated spermatozoa through immunofluorescence and immunoblotting, and investigate ...
