Siglec–15 promotes a feed-forward loop between TNBC cells and macrophages via the NF- κB/DcR3/CCL18/STAT3 axis

This study reveals that Siglec-15 drives a feed-forward loop in triple-negative breast cancer by activating the NF-κB/DcR3 pathway to induce M2-like macrophage polarization and CCL18 secretion, which in turn enhances Siglec-15 expression via STAT3 phosphorylation to further promote tumor progression.

Bodily Self-Perception During Vestibular Galvanic Stimulation in Virtual Reality: A Replication and Extension of Karnath et al. (2019)

This study replicated and extended Karnath et al. (2019) by using virtual reality and galvanic vestibular stimulation on twenty healthy participants, ultimately confirming that neither DC nor AC GVS significantly modulates perceived arm size, while also failing to replicate the original study's finding regarding body side effects.

Water oxidation-driven histidine dioxidation enables probe-free proximity labeling

This study introduces PF-Map, a probe-free proximity labeling strategy utilizing an organic photocatalyst (IDM) to generate hydroxyl and superoxide radicals that dioxidize proximal histidine residues into stable, chemically addressable states, thereby enabling minimally biased spatial proteome mapping in live cells and revealing hidden vesicle trafficking subproteomes missed by traditional probe-dependent methods.

Bioactive dietary polyphenols modulate hippocampal inflammasome activation and sex- specific affective behavioral deficits following peripheral Foxp3 + regulatory T cell depletion

This study demonstrates that peripheral Foxp3+ regulatory T cell depletion triggers sex-specific hippocampal inflammasome activation and affective behavioral deficits, which are selectively attenuated by bioactive dietary polyphenols in male but not female subjects.

Sambucus nigra L. preserves redox homeostasis and modulates autophagy and UPS in oxidatively stressed HT-22 hippocampal cells

The aqueous extract of *Sambucus nigra* L. flowers protects oxidatively stressed HT-22 hippocampal cells by primarily restoring redox homeostasis through antioxidant mechanisms, while also modulating autophagy and the ubiquitin-proteasome system to enhance cell viability.

Proteomic alterations in mitochondrial metabolism during the early development from the beating heart primordium to the primitive heart tube in rats

This study reveals that the transition from the beating heart primordium to the primitive heart tube in rats involves coordinated upregulation of mitochondrial metabolism proteins, particularly those in the tricarboxylic acid cycle, likely driven by insulin-like growth factor 2 to support the increasing energetic demands of early cardiac development.
