Oocyte analysis of species Arca noae Linnaeus, 1758 (Mollusca: Bivalvia) from Adriatic Sea
The European Zoological Journal, 2021 Noah’s ark shellfish is a commercially important species in the Adriatic Sea, but its populations are overexploited. The objective of this study was to complete the information on reproduction for potential commercial breeding.

Advanced Science, EarlyView.Oocytes play crucial roles in maintaining ovarian fate in adult gonochoristic fish. Targeted oocyte ablation with aromatase inhibition triggers the activation of surviving germline stem cells and the transdifferentiation of somatic cells from granoulosa/theca to Sertoli/Leydig lineages, inducing a complete and functional female‐to‐male sex reversal ...

Advanced Science, EarlyView.Maternal exercise (ME) increases apelin abundance across maternal and fetal tissues and is associated with improved fetal osteogenesis under POLG mutation‐induced mitochondrial dysfunction. Apelin‐APJ signaling is linked to enhanced mitochondrial function, Akt phosphorylation, and ATF4‐RUNX2 association, supporting coordinated fetal bone remodeling ...

Advanced Science, EarlyView.Phase separation of SF3B1 acts as a key regulatory mechanism for dynamic alternative splicing throughout early mouse embryogenesis. Its absence triggers extensive splicing errors, which induce persistent DNA damage, defective cell cycle progression, and failed cell lineage commitment, and ultimately hinder the normal growth and development of ...

Advanced Science, EarlyView.A minimal extracellular epitope from voltage‐gated sodium channel NaV1.7 was engineered into an isotope‐labelled antigen for antigen‐detected nuclear magnetic resonance (NMR). Together with AlphaFold2 (AF2), this enabled structure‐guided selection of R4C8, a human NaV1.7‐selective nanobody that labels fixed NaV1.7‐expressing cells and produces staining

CRISPR and Gene Augmentation Rescue Trabecular Meshwork Dysfunction in iPSC Models of Lowe Syndrome
Advanced Science, EarlyView.By modeling Lowe syndrome using patient‐derived iPSCs, this study establishes a human disease model that faithfully recapitulates OCRL deficiency‐associated ciliary and cytoskeletal defects. The model enables evaluation of both mutation‐agnostic DNA augmentation and CRISPR‐mediated mutation correction strategies, both of which restore OCRL function and
