Morning Training Improves Endurance Adaptation in Mice
2026-09-09
Hesketh and colleagues show that early-active-phase endurance training produces larger performance gains than late-active-phase training in female mice, even when the early-active group completes less absolute work. The study links this adaptation to selected skeletal-muscle metabolic and contractile changes rather than to measurable differences in muscle or liver glycogen, refining how exercise timing should be interpreted in circadian physiology.

QPRT Promotes Breast Cancer Invasion via Myosin Light Chain
2026-09-08
Liu and colleagues show that elevated quinolinate phosphoribosyltransferase (QPRT) is associated with breast cancer invasiveness and promotes migration through a purinergic, Rho–ROCK–PLC–MLCK signaling axis that increases myosin light chain phosphorylation. The study positions QPRT as a mechanistic link between NAD+ metabolism and cytoskeletal remodeling, while also illustrating how pharmacological pathway perturbation can test invasion mechanisms.

Standardized Whole-Blood Stimulation in Immunometabolism
2026-09-08
This protocol establishes a reproducible whole-blood platform for testing how metabolic interventions alter immune-cell cytokine responses to defined microbial and pattern-recognition receptor stimuli. Its main contribution is methodological: it connects standardized sample handling, controlled stimulation, metabolic perturbation, and cytokine quantification in a format suitable for comparative and cohort-based immunometabolism research.

GRA12 and Conserved Toxoplasma Virulence
2026-09-07
This preprint uses pooled in vivo CRISPR-Cas9 screens across Toxoplasma gondii strains and mouse backgrounds to identify virulence factors that remain important across host–parasite combinations. GRA12 emerged as a conserved dense-granule effector that protects the parasitophorous vacuole from immune-associated collapse and premature parasite egress, providing a framework for studying broadly transferable mechanisms of infection.

UBR1 and UBR2 as Mammalian ER Stress Sensors
2026-09-04
The reference study identifies the N-recognin E3 ligases UBR1 and UBR2 as stress-responsive regulators of mammalian endoplasmic reticulum protein quality control. Its findings connect N-degron-mediated ubiquitination with ER stress adaptation and provide a framework for interpreting trafficking and apoptosis assays without equating all ER perturbations with the same molecular pathway.

Drug Response Metrics in Cancer: Beyond Viability
2026-09-04
Hannah R. Schwartz’s dissertation distinguishes relative viability from fractional viability, showing that growth inhibition and cell killing are related but non-equivalent drug-response processes. This framework supports more precise interpretation of in vitro cancer experiments by accounting for response magnitude, mechanism, and timing rather than relying on a single viability endpoint.

Direct Mouse Genotyping Kit: Practical PCR Workflow
2026-09-03
The Direct Mouse Genotyping Kit simplifies PCR amplification from mouse tissue by combining direct genomic DNA release with a ready-to-use PCR master mix with dye, avoiding conventional DNA purification for routine assays. It is appropriate for mouse genetic screening and high-throughput genotyping, but direct lysates are not the preferred input for applications requiring ultra-pure or high-molecular-weight DNA.
