Oocyte–cumulus cell interaction: a key factor in early embryo development
Biological Reviews, EarlyView.ABSTRACT The evaluation of oocyte competence is a fundamental step in achieving successful outcomes following assisted reproduction techniques (ART). At present, however, conventional oocyte maturation assessment is carried out by morphological observation, which is a subjective method that does not consider molecular features.

Toxic Effects of Miller on Chromosomes and Sperms of Albino Males Mice
Science Journal of University of Zakho, 2014 The genotoxicity of Miller (glyphosate) herbicide was evaluated in males albino mice Mus muscles BALB/c strain. The tested parameters were chromosomal aberrations and sperm abnormalities to evaluate a possible damage effects on genetic material and ...

The costs of extra‐pair behaviours in birds
Biological Reviews, EarlyView.ABSTRACT Extra‐pair behaviours – reproductive behaviours, including those related to copulation and paternity of offspring, amongst animals outside of a social pair bond – have long intrigued behavioural ecologists, particularly from the female animal's perspective.

Cytoskeleton, EarlyView.ABSTRACT Of the three types of cytoskeleton known in animals—actin, microtubules, and intermediate filaments—only actin and microtubules exist in plants. Both play important roles in cellular shaping, organelle movement, organization of the endomembrane system, and cell signaling.

Engineering Applications of Computational Fluid Mechanics, 2020 This paper presents a numerical study on a sperm swimming in a viscous fluid by using an immersed boundary-lattice Boltzmann method (IB-LBM). The sperm is modeled simply by integrating a slender tail and an elliptical head.

Cytoskeleton, EarlyView.ABSTRACT Post‐translational modifications (PTMs) to tubulin subunits in microtubule filaments are thought to comprise a component of the tubulin code that specifies microtubule functions in cell physiology and animal development. Acetylation of Lysine‐40 (K40) on α‐tubulin (αTub‐K40ac) and glutamylation of both α‐ and β‐tubulin are two tubulin PTMs of ...

Cytoskeleton, EarlyView.ABSTRACT Cooperativity between cytoskeletal proteins is crucial for spatiotemporal coordination in biological processes, like oogenesis. In mammalian and Drosophila oogenesis, proper assembly and function of actin networks require coordination between actin assembly factors Spire and formins, as well as actin‐associated proteins like myosins and Rab ...

Developmental Dynamics, EarlyView.Abstract Background Biomineralization is a vital biological process through which organisms produce mineralized structures such as shells, skeletons, and teeth. Microtubules are essential for biomineralization in various eukaryotic species; however, their specific roles in this process remain unclear.

CCDC28A deficiency causes head-tail coupling defects and immotility in murine spermatozoa
Scientific ReportsMale infertility presents a substantial challenge in reproductive medicine, often attributed to impaired sperm motility. The present study investigates the role of CCDC28A, a protein expressed specifically in male germ cells, whose paralog CCDC28B has ...
