Sodium Overload, Mitochondria, and NECSO
2026-08-12
Qiao et al. identify mitochondrial energy failure as the mechanistic link between TRPM4-mediated sodium influx and necrosis by sodium overload (NECSO). The study connects sodium accumulation, NCLX-dependent calcium loss, impaired oxidative phosphorylation and TCA-cycle activity, ATP depletion, Na/K-ATPase failure, and cellular lysis in a unified model of necrotic injury.

Sulfo-NHS-SS-Biotin: Practical Labeling Guide
2026-08-10
Sulfo-NHS-SS-Biotin provides water-compatible, amine-reactive biotinylation for protein labeling, cell-surface analysis, and affinity capture. It is appropriate when reversible retrieval of the biotin tag is useful, but it requires fresh preparation, rapid use, compatible buffers, and validation before application to sensitive proteins or intact-cell assays.

In Vitro Drug Responses in Cancer
2026-08-09
Hannah Schwartz’s dissertation distinguishes relative viability from fractional viability, showing that these commonly conflated readouts capture different relationships between proliferative arrest and cell death. Its main practical implication is that drug-response studies should interpret endpoint identity and response timing together rather than treating a single viability value as a complete measure of drug activity.

Adamtsl3, MMP9, and Adult Cortical Plasticity
2026-08-08
The reference study identifies Adamtsl3 as a cell-autonomous regulator of perineuronal net integrity in parvalbumin-positive interneurons. Its genetic, imaging, biochemical, and plasticity experiments connect Adamtsl3 loss to elevated MMP9 activity, reduced Otx2 uptake, oxidative stress, and the reactivation of juvenile-like cortical plasticity.
