Understanding extracellular vesicles in antiaging

open access: yesPeriodontology 2000, EarlyView.
Abstract Background Aging is a multifactorial process marked by gradual cellular dysregulation, regulated by hallmarks, including genomic instability, mitochondrial dysregulation, and chronic inflammation. Extracellular vesicles (EVs), especially exosomes, have emerged as pivotal mediators of cell‐to‐cell communication with potential roles in both ...

Cytologic Characteristics of the Feline Ovary at Different Sexual Stages

open access: yesVeterinary Clinical Pathology, EarlyView.
ABSTRACT Background Cytology is a valuable diagnostic tool in veterinary medicine, allowing rapid and minimally invasive diagnosis. However, its application in the reproductive tracts of small animals is limited, primarily used to assess mammary masses and stage the estrous cycle.

Systematic Comparison of High‐Fat Diet– and Streptozotocin‐Induced Prediabetic Obese C57BL/6J Mouse Models: A Sex‐Based Protocol Optimization Study

open access: yesDiabetes, Obesity and Metabolism, Volume 28, Issue 11, Page 9897-9918, November 2026.
ABSTRACT Aims Animal models of prediabetes (Pre‐DM) are essential for studying metabolic disease and testing therapies, yet high‐fat diet (HFD) and HFD‐plus‐streptozotocin (STZ) protocols vary in feeding duration, STZ dose, and diagnostic criteria and rarely account for sex.

Effects of GnRH administration on ovulation and fertility in ewes subjected to estrous synchronization

open access: yesRevista Brasileira de Zootecnia, 2012
The objective of this study was to verify the effects of GnRH on ovulation and pregnancy of ewes subjected to a short-term synchronization of estrus. Santa Inês and crossbred Santa Inês/Dorper ewes received 60 mg MAP sponges during 6 days plus 300 IU eCG

Safe and Stable Germline Transmission of MSTN Mutations in Cattle

open access: yesAnimal Genetics, Volume 57, Issue 5, October 2026.
ABSTRACT With the global population expected to reach 10 billion by 2050, sustainable livestock production is critical. Gene editing of the myostatin (MSTN) gene represents a promising strategy to enhance muscle growth in cattle. In this study, MSTN‐mutated founder (F0) cows were used to generate F1 offspring via ovum pick‐up, in vitro fertilization ...

On the importance of including both sexes in animal studies – insights from home‐cage monitoring

open access: yesBiological Reviews, Volume 101, Issue 5, Page 2408-2426, October 2026.
ABSTRACT A review of behavioural studies using home‐cage monitoring (HCM) systems revealed that over 61% of studies used only male subjects, with only 24% including both sexes, despite evidence of substantial behavioural differences between male and female animals. This bias could influence the outcomes of biomedical research.

Ciliary Ift20 and Wwtr1 Coordinate Transforming Growth Factor‐β Receptor II Signaling to Maintain Bone–Fat Balance in Skeletal Homeostasis

open access: yesMedComm, Volume 7, Issue 10, October 2026.
Deletion of Ift20 and Wwtr1 in osteoprecursors promoted adipogenic differentiation while suppressing osteogenesis and bone remodeling through dysregulation of TGF‐β signaling. Mechanistically, Ift20 stabilized TβRII by inhibiting c‐Cbl‐mediated ubiquitination and proteasomal degradation. In parallel, Wwtr1 functioned as a transcriptional regulator that
