LASP1, a Novel Protein in Spermatozoa and Acrosome Reaction

Molecular Reproduction and Development, Volume 93, Issue 7, July 2026.
LASP1 is expressed in spermatozoa, binds to F‐actin, and builds up the equatorial ring structure during acrosome reaction, which is important for hyaluronan receptor surface presentation. ABSTRACT LIM and SH3 protein 1 (LASP1) is a widely expressed scaffold protein associated with actin‐rich structures. In Lasp1‐knockout mice, reproductive defects such

Panax ginseng induces the expression of CatSper genes and sperm hyperactivation

Asian Journal of Andrology, 2014
The cation channel of sperm (CatSper) protein family plays important roles in male reproduction and infertility. The four members of this family are expressed exclusively in the testis and are localized differently in sperm. To investigate the effects of

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 ...

Investigation of the effect of diazinon on CatSper 1 gene expression, sperm motility and germinal epithelium thickness in adult male mice [PDF]

مجله علمی دانشگاه علوم پزشکی کردستان, 2020
Background and Aim: Genetic changes and mutations in the genes involved in spermatogenesis can occur by environmental and congenital factors. Considering, the extensive use of diazinon in the farms and because we found no study on the effects of diazinon

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 ...

Lupeol and pristimerin do not inhibit activation of the human sperm CatSper Ca(2+)-channel [version 2; peer review: 2 approved, 1 approved with reservations]

F1000Research, 2022
Opposing findings have been published on the regulation of the sperm-specific Ca2+ channel CatSper (cation channel of sperm) in human sperm cells by the plant triterpenoids lupeol and pristimerin.

Calpain‐1 and Cholesterol Regulate the Dynamics of the Lipid Membrane Domains Essential for Suitable Capacitation and Acrosomal Reactions

Journal of Cellular Physiology, Volume 241, Issue 2, February 2026.
The role of calpain‐1 and cholesterol during capacitation. The activation of calpain‐1 and cholesterol redistribution directs distinct events involved in capacitation, including the degradation of the spectrin cytoskeleton, protein phosphorylation at Tyr, actin polymerization, lipid rafts remodeling, and calcium influx, among others. ABSTRACT Calpain‐1

Deciphering mRNA Translation During Sperm Capacitation: A New Frontier in Fertility Research

Molecular Reproduction and Development, Volume 93, Issue 2, February 2026.
ABSTRACT Male infertility accounts for approximately 50% of infertility cases, with nearly 30% remaining unexplained after standard evaluations. This highlights the need for a better understanding of sperm function to advance diagnostic and therapeutic strategies. Sperm were long considered translationally quiescent; however, emerging evidence suggests
