Tag-and-Trigger: Basolateral Amygdala Stimulation Reinforces Behaviorally Tagged Hippocampus-Cortical Circuits to Enhance Memory Consolidation and Reverse Alzheimer's Disease Pathology in 5XFAD Mice

This study demonstrates that a "Tag-and-Trigger" paradigm, which combines spatial learning with precisely timed basolateral amygdala stimulation, rescues memory deficits, restores synaptic plasticity, and reverses Alzheimer's pathology in 5XFAD mice by leveraging activity-dependent mechanisms to reinforce specific hippocampal-cortical circuits.

A highly contiguous reference genome for the Argentine hake (Merluccius hubbsi Marinni 1923, Gadiformes, Merluccidae)

This study presents the first high-quality, de novo reference genome for the economically and ecologically vital Argentine hake (*Merluccius hubbsi*), which not only elucidates its evolutionary history and demographic fluctuations but also confirms its current robust genetic diversity and lack of recent inbreeding despite historical climate changes and intense fishing pressure.

The IGF2BP2/HMGA2/FOSL1 Axis Controls Cell Plasticity and Therapy Resistance in Neuroblastoma

This study identifies the m6A reader IGF2BP2 as a critical regulator of the HMGA2/FOSL1 axis that drives the adrenergic-to-mesenchymal transition, chromatin remodeling, and therapy resistance in high-risk neuroblastoma, thereby revealing epitranscriptomic and transcriptional vulnerabilities for therapeutic intervention.

Prevalence of Virulence-Associated Genes in Culture-Confirmed Vibrio cholerae Isolates: A PCR-Based Study

This study analyzed 125 culture-confirmed *Vibrio cholerae* isolates from Ethiopian cholera outbreaks using multiplex PCR and found that all nine targeted virulence-associated genes were present across the isolates, with *hlyA* being the most prevalent, thereby highlighting the significant pathogenic potential of circulating strains and establishing a molecular baseline for future epidemiological research in the region.

Correcting mutant CFTR with a stabilizing nanobody reveals a novel active conformation of the channel

This study demonstrates that delivering a stabilizing nanobody (T2a) via mRNA lipid nanoparticles corrects F508del-CFTR trafficking and reveals a novel, non-canonical open-channel conformation, offering a new therapeutic paradigm for cystic fibrosis and other protein misfolding diseases.

Umbilical cord-derived mesenchymal stromal cells attenuate neurogenic degeneration in infantile acute encephalopathy mice

This study demonstrates that intravenous administration of human umbilical cord-derived mesenchymal stromal cells (UC-MSCs) attenuates neurogenic degeneration and behavioral abnormalities in an infantile acute encephalopathy mouse model by suppressing neuroinflammation and modulating microglial activation.

Alpha Reactivity Dynamics Reveal Multi-System Variability Without Global Alpha Slowing in Fragile X Syndrome

This study demonstrates that Fragile X syndrome is characterized by region-specific alpha reactivity deficits and distributed network alterations without global alpha slowing, supporting a multi-system model of dysfunction where these dynamics serve as a promising translational biomarker.

TopBP1 condensates orchestrate nuclear actin assembly to ensure genome stability

This study reveals that TopBP1 condensates act as central architectural hubs that orchestrate nuclear actin assembly and nuclear envelope integrity via ATR-mTOR signaling to maintain genome stability during replication stress, a mechanism that is hijacked by chemo-resistant colorectal cancer cells to promote survival.
