MN•CS•IO System: Cross‐Species Study for HBB Function in High‐Altitude Hypoxia Adaptation

Advanced Science, EarlyView.
We developed an integrative mesh‐nanorod sorting, chitosan nanoparticle delivery, and intraosseous injection (MN•CS•IO) system to investigate HBB in high‐altitude hypoxia adaptation. Transplanting Tibetan animals' HBB‐modified Lin‐ cells into mice achieved 95.59% transfection efficiency and 8.15% HBB expression. High‐altitude HBB recipients upregulated

Divergent vigilance strategies in sympatric seals facing shared predation risk

FACETS
Predator–prey dynamics shape animal behaviour and distribution, and vary across space and time. As Arctic ecosystems change, long-standing ecological relationships may shift, yet species’ behavioural responses to changing predation pressure remain poorly

Status of harbour seals (Phoca vitulina) in Atlantic Canada

NAMMCO Scientific Publications, 2010
Harbour seals are associated with small islets, reefs and rocks exposed at low tide and estuarine habitats throughout eastern Canada. Evidence of harvesting by indigenous people has been found in pre-European contact archaeological excavations.

Neonatal Sevoflurane Exposure Induces Long‐Term Cognitive Impairment via Epigenetically Mediated MMP9 Activation and Perineuronal Net Disruption in the Hippocampal CA2

Advanced Science, EarlyView.
Hippocampal CA2 perineuronal nets ensheathing excitatory pyramidal neurons are selectively vulnerable to repeated neonatal sevoflurane exposure. Epigenetic upregulation of MMP9 via reduced H3K27me3 disrupts PNN integrity, impairs BDNF–TrkB signaling, and causes synaptic protein loss and dendritic spine deficits, leading to persistent social and spatial

ELF5‐Mediated Enhancer–Promoter Interaction Regulates LALBA Expression in Ovine Mammary Gland

Advanced Science, EarlyView.
In the study, we systematically investigate the epigenetic mechanisms underlying lactation traits in sheep by integrating transcriptomic, chromatin accessibility, histone modification, and functional analyses. We identify a super‐enhancer at the LALBA locus and demonstrate that enhancer E4 functions as its core regulatory element.
