Testicular mRNA‐LNP Delivery: A Novel Therapy for Genetic Spermatogenic Disorders

open access: yesAdvanced Science, Volume 13, Issue 22, 17 April 2026.
In the current study, we developed a novel therapy for genetic spermatogenic disorders. It was revealed that in vivo delivery of mRNA LNP3 could restore spermatogenesis in Msh5D486Y/D486Y and Maps KO mouse models with meiotic arrest. Notably, the offspring without genomic integration was born using ICSI derived from the rescue of Msh5D486Y/D486Y mouse ...

NuSAP Safeguards Centriole Integrity to Mediate CEP57‐CEP152 Torus Recruitment for Proper Engagement

open access: yesAdvanced Science, Volume 13, Issue 19, 2 April 2026.
This study reveals a novel role for the microtubule stabilizer NuSAP at centrioles. NuSAP depletion destabilizes the centriole's tubulin structure, causing premature disengagement, PCM defects, and mis‐localization of the CEP57‐CEP63‐CEP152 complex. By reinforcing centriole architecture, NuSAP enables early CEP57 loading and initiates a newly proposed ...

Identification of A p300–SP1–BRD4 Transcriptional Axis as a Key Driver of AR Hyperactivation in Polycystic Ovarian Syndrome

open access: yesAdvanced Science, Volume 13, Issue 23, 23 April 2026.
This study reveals a pivotal epigenetic regulatory role for the histone acetyltransferase p300, demonstrating that its acetylation of histone 3 at lysine 18 and 27 (H3K18ac and H3K27ac), alongside the formation of the p300/BRD4/SP1 complex, drives AR activation and ovarian fibrosis in PCOS.

PIK3CA Mutations Downregulate PPT1 to Promote Adipogenesis by Suppressing P300 Depalmitoylation and Phase Separation

open access: yesAdvanced Science, Volume 13, Issue 19, 2 April 2026.
This study demonstrates that somatic PIK3CA mutations suppress PPT1 expression via activation of the PI3K–AKT–c‐JUN axis. This reduction in PPT1 weakens its interaction with P300, thereby increasing palmitoylation at C1176 of P300 and protecting P300 from lysosomal degradation.

Implementation of immature oocytes by cryopreservation technique and subsquent in vitro maturation and fertilization post-thawing

open access: yes, 2011
The aim of this study was to cryopreserve by vitrification by propylene glycol (PROH) and dimethylsulfoxide (DMSO) immature bovine oocytes in straws and to investigate the effects of vitrification on post-thaw oocyte maturation and fertilization. A total of 983 cumulus oocyte complexes were obtained by follicle aspiration from 263 ovaries of cows ...

Molecular bases of insect odorant receptor function: specificity and evolution

open access: yesBiological Reviews, Volume 101, Issue 2, Page 1036-1049, April 2026.
ABSTRACT Insect odorant receptors (ORs) are a class of chemoreceptors that insects use to detect volatile cues in their environment. In recent years, major advances in the field of structural biology have made it possible to obtain the first structures of insect ORs.

One Case of Transvaginal and Transabdominal Oocyte Retrieval Guided by Ultrasound Probe: A Case Report

open access: yesClinical Case Reports, Volume 14, Issue 4, April 2026.
ABSTRACT Transvaginal ultrasound‐guided oocyte retrieval is routine for assisted reproduction, but unfit for some special patients. We report an elderly infertile patient with adenomyosis, whose transvaginal retrieval was high risk. Intraoperative conversion to transabdominal retrieval succeeded safely.

Look Who Is Talking: Extracellular Vesicles as Mediators of Intercellular and Interorgan Communication

open access: yesComprehensive Physiology, Volume 16, Issue 2, April 2026.
Extracellular vesicles (EVs) mediate intercellular and interorgan communication during both physiological and pathological conditions. EVs include exosomes, ectosomes, and apoptotic bodies and contain bioactive molecules. EVs are delivered to proximal cells or can travel in bodily fluids and reach distant organs, where they trigger a response from the ...
