Breakpoint analysis of the pericentric inversion distinguishing human chromosome 4 from the homologous chromosome in the chimpanzee (Pan troglodytes)

Human Mutation, 2005
The study of breakpoints that occurred during primate evolution promises to yield valuable insights into the mechanisms underlying chromosome rearrangements in both evolution and pathology.

A Two‐Protein Chemoreceptor Complex Regulates Oxygen Thresholds in Bacterial Magneto‐Aerotaxis

Advanced Science, EarlyView.
Magnetotactic bacteria align with Earth's magnetic field, helping them migrate toward low‐oxygen environments. This study reveals how Magnetospirillum gryphiswaldense uses a specialized flavin adenine dinucleotide (FAD)‐dependent chemoreceptor, composed of two interacting proteins, for precise navigation in oxygen gradients.

Tracing and Capturing the Epiblast Pluripotency of Sheep Preimplantation Embryos

Advanced Science, EarlyView.
This study performs a comprehensive single‐cell transcriptome analysis of sheep embryos from embryonic (E) day 1 to E14 to elucidate the mechanism of early lineage specification and the pluripotency changes (naïve, formative, and primed) of epiblast.

QSOX2‐Mediated Disulfide Bond Modification Enhances Tumor Stemness and Chemoresistance by Activating TSC2/mTOR/c‐Myc Feedback Loop in Esophageal Squamous Cell Carcinoma

Advanced Science, EarlyView.
High QSOX2 enhances stemness, drug resistance, and metastasis of ESCC cells. QSOX2‐mediated disulfide bond modification activates mTOR/c‐Myc signaling. CAFs‐secreted IGF‐1 drives mTOR/c‐Myc/QSOX2 positive feedback loop. Combining Ebselen, rapamycin, and cisplatin induces tumor dormancy in mice.

A companion to the preclinical common data elements for rodent genetic epilepsy models. A report of the TASK3‐WG1B: Paediatric and genetic models working group of the ILAE/AES joint translational TASK force

Epilepsia Open, EarlyView., 2022
Abstract Rodent models of epilepsy remain the cornerstone of research into the mechanisms underlying genetic epilepsy. Reproducibility of experiments using these rodent models, occurring across a diversity of laboratories and commercial vendors, remains an issue impacting the cost‐effectiveness and scientific rigor of the studies performed.
