Age- and substrain-dependent sperm abnormalities in BALB/c mice and functional assessment of abnormal sperm by ICSI [PDF]

Human Reproduction, 2008
Male BALB/c mice produce a high proportion of morphologically abnormal sperm. Although the BALB/c male may be a useful model of human male infertility, it remains unclear whether the sperm abnormality rate (SAR) is affected by age or the BALB/c substrain.SARs (head shape) were assessed in three BALB/c substrains (A, AnN, ByJ) at 7 and 9 weeks and 6-10 ...

Heat Stress in Quail: Impacts on Health and Productivity, and Mitigation Strategies

Animal Research and One Health, EarlyView.
Heat stress disrupts physiological homeostasis in quail, inducing oxidative stress, immune dysregulation, and metabolic imbalance, which impair growth, reproduction, product quality, and welfare. Integrating nutritional, environmental, and genetic–epigenetic strategies enhances thermotolerance, sustains productivity, and supports climate‐smart quail ...

Grandparent Prenatal Tobacco, Alcohol, Coffee, and Tea Consumption and Autism in the Third Generation

Autism Research, EarlyView.
ABSTRACT Exogenous prenatal exposures may affect neurodevelopment across multiple generations. We investigated grandmother and grandfather smoking, alcohol, coffee, and tea consumption during pregnancy in relation to their grandchildren's risk of autism spectrum disorder (ASD).

The Role of Sperm Centrioles in Human Reproduction – The Known and the Unknown

Frontiers in Cell and Developmental Biology, 2019
Each human spermatozoon contains two remodeled centrioles that it contributes to the zygote. There, the centrioles reconstitute a centrosome that assembles the sperm aster and participate in pronuclei migration and cleavage. Thus, centriole abnormalities

Heat stress in spermatogenesis: a redox‐dependent decision network linking ROS, autophagy, and regulated cell death

Biological Reviews, EarlyView.
ABSTRACT Heat stress (HS) is an increasing threat to male reproductive health, disrupting spermatogenesis through complex and interdependent cellular responses within the seminiferous epithelium. Although excessive reactive oxygen species (ROS) production is a hallmark of HS, ROS also act as central regulators of cell fate decisions beyond their role ...

The Influence of Drosophila Spire and Myosin V During Mid‐Oogenesis Is Independent of Their Direct Interaction

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 ...
