Xenogeneic Mitochondrial Transplantation Improves Selected Age‐Associated Phenotypes in Mice

open access: yesAdvanced Science, EarlyView.
Yak‐derived xenogeneic mitochondrial transplantation improves selected age‐associated phenotypes in mice, enhances mitochondrial functional readouts, and engages host mitochondrial quality‐control pathways. Broad tissue biodistribution, increased ATP production and mtDNA copy number, reduced ROS levels and dysfunctional mitochondria, improved motility ...

Endobody: Genetically Encodable Nanobody‐CPP Chimeras for Degradation of Membrane and Extracellular Proteins

open access: yesAdvanced Science, EarlyView.
We introduced genetically encodable, receptor‐independent nanobody‐CPP chimeras, termed endobodies, as robust and modular membrane protein degraders. Additionally, proteasome‐targeting domain (PTD)‐tethered endobody demonstrates further enhanced degradation potency.

NAD+ Metabolism Licenses Zygotic Genome Activation via PARP7‐Mediated ADP‐Ribosylation of UHRF1 in Mouse Early Embryos

open access: yesAdvanced Science, EarlyView.
This study uncovers a metabolic‐epigenetic axis licensing zygotic genome activation (ZGA) in mouse embryos. A developmental decline in NAD+ levels activates PARP7, which mono‐ADP‐ribosylates and stabilizes UHRF1. This modification promotes the establishment of permissive histone acetylation marks, thereby facilitating timely ZGA.

The KIF6‐RBP Complex Orchestrates mRNA Transport Required for Sperm Flagellar Assembly

open access: yesAdvanced Science, EarlyView.
Two homozygous deleterious KIF6 variants are identified in unrelated men with impaired sperm motility. Mouse models and multi‐omics analyses reveal that KIF6 cooperates with the RNA‐binding proteins FMRP and FXR1 to deliver mRNAs essential for sperm flagellar assembly, linking disrupted mRNA transport to reduced abundance of key structural and ...

A Metabolomic Profile of Seminal Fluid in Extremely Severe Oligozoopermia Suggesting an Epididymal Involvement

open access: yesMetabolites, 2022
Male infertility has increased in the last decade. Pathophysiologic mechanisms behind extreme oligospermia (EO) are not yet fully understood. In new “omics” approaches, metabolomic can offer new information and help elucidate these mechanisms.

LXR regulate cholesterol homeostasis in the proximal mouse epididymis.

open access: yes, 2010
Oxysterol nuclear receptors liver x receptors (LXRalpha and LXRbeta) regulate lipid homeostasis when cells have to face high amounts of cholesterol and/or fatty acids.

Developmental morphology of claspers and clasper‐glands during maturation in Potamotrygon wallacei (Chondrichthyes: Potamotrygoninae)

open access: yesThe Anatomical Record, EarlyView.
Abstract The claspers are the copulatory organs in male elasmobranchs, responsible for directing the semen into the female cloaca (C). However, the microscopic morphology of the claspers remains poorly understood. This study describes the morphology of the claspers and clasper glands (CGs) of cururu stingray (Potamotrygon wallacei) at different ...

Effect of alcoholic extract of soy bean consumption by pregnant mice on the testis and epididymis of their male offspring's

open access: yesAl-Mustansiriyah Journal of Pharmaceutical Sciences, 2013
Soy is flavones are phytoestrogens with potential hormonal activity due to their similar chemical structure to 17-B-estradiol. The increasing availability of Soy is flavones throughout the food supply and through use of supplements has prompted ...

Modern competency‐based teaching of human sexual development

open access: yesAnatomical Sciences Education, EarlyView.
Abstract Embryology is an integral part of anatomy and a key subject in basic medical education. The development of the sexual tract, which is closely associated with the formation of the urinary tract and the organs of continence, is particularly complex and relevant for many medical disciplines.
