Spatiotemporal distribution of neural crest cells in the common wall lizard Podarcis muralis
Developmental Dynamics, Volume 254, Issue 6, Page 551-567, June 2025.Abstract Background Neural crest cells (NCCs) are migratory embryonic stem cells that give rise to a diverse set of cell types. Here we describe the dynamic distribution of NCCs in developing embryos of the common wall lizard Podarcis muralis inferred from 10 markers.

A Comprehensive Review of Mitochondrial Complex I During Mammalian Oocyte Maturation
genesis, Volume 63, Issue 3, June 2025.ABSTRACT This review provides a comprehensive overview of Complex I during mammalian oocyte maturation. Complex I (NADH:ubiquinone oxidoreductase) is a crucial member of the electron transport chain and serves two principal functions during oxidative phosphorylation: NADH oxidation and proton pumping.

Sperm Cells as DNA Vectors for the Preparation of Transgenic Animals
CHIMIA, 1999 Sperm-mediated DNA transfer strategy which has been used for the preparation of genetically modified, transgenic organisms is discussed, and sperm-mediated transgenesis of Xenopus laevis frogs with retroviral Rous sarcoma virus DNA is summarized.

Plant Direct, Volume 9, Issue 6, June 2025.ABSTRACT An efficient nitrate uptake system contributes to the improvement of crop nitrogen use efficiency under low nitrogen availability. The High Affinity nitrate Transport System (HATS) in plants is active in low range of external nitrate and is mediated by a two‐component system (high affinity transporters NRT2 associated to a partner protein NRT3

Journal of Peptide Science, Volume 31, Issue 6, June 2025.This study cyclized conotoxin Vc1.1 using polyethylene glycol (PEG) linkers of different lengths and demonstrates that linker length modulates the peptide's helicity, thereby influencing its biological activity and stability. ABSTRACT α‐Conotoxin Vc1.1 is a disulfide‐rich peptide and a promising drug candidate for treating neuropathic and chronic pain.

Vestibular modulation by stimulant derivatives in a pentameric ligand‐gated ion channel
British Journal of Pharmacology, Volume 182, Issue 12, Page 2790-2802, June 2025.Background and Purpose Allosteric modulation of pentameric ligand‐gated ion channels (pLGICs) are critical for the action of neurotransmitters and many psychoactive drugs. However, details of their modulatory mechanisms remain unclear, especially beyond the orthosteric neurotransmitter‐binding sites. The recently reported prokaryotic symbiont of Tevnia

The FEBS Journal, Volume 292, Issue 11, Page 2715-2736, June 2025.The silencing of transposable elements is mediated by piRNAs through post‐transcriptional and transcriptional regulation. In Drosophila, piRNAs are processed within unique non‐membrane structures: nuage in germline cells and Yb bodies in somatic gonadal cells.
