EdU Flow Cytometry Assay Kits (Cy5): Practical Guide
2026-09-13
EdU Flow Cytometry Assay Kits (Cy5) provide a workflow for measuring DNA synthesis during S-phase by combining EdU incorporation with copper-catalyzed azide-alkyne cycloaddition (CuAAC) and Cy5 fluorescence. The assay is suitable for flow cytometry-based proliferation studies, but it should not be used alone to infer viability, completed cell division, cell-cycle duration, or genotoxicity.

FGFR3 Inhibition in SLC26A2 Chondrodysplasia
2026-09-12
The reference study combines genetic mouse models, inducible postnatal deletion, chondrocyte assays, and pharmacological intervention to show that excessive FGFR3 signaling contributes to SLC26A2-related chondrodysplasia. Its findings support NVP-BGJ398 as a preclinical tool for testing FGFR3 pathway inhibition, while also highlighting the limits of translating a pan-FGFR inhibitor from mice to human skeletal disease.

Sex Differences in Angiotensin II Hypertension
2026-09-11
Xue, Pamidimukkala, and Hay used radiotelemetry in conscious, freely moving mice to show that chronic angiotensin II produces a substantially greater hypertensive response in males than in females. Gonadectomy, baroreflex testing, and ganglionic blockade further linked this divergence to sex-dependent hormonal and autonomic regulation rather than to baseline blood pressure differences alone.

WNT5a/GSK3/β-Catenin Controls FAP Adipogenesis
2026-09-10
The reference study identifies the WNT5a/GSK3/β-catenin axis as a central regulator of adipogenic differentiation in skeletal muscle fibro/adipogenic progenitors (FAPs). By combining pharmacological perturbation, single-cell mass cytometry, transcriptomic integration, and mouse models, it links β-catenin stabilization to reduced PPARγ-driven adipogenesis and improved satellite-cell support.

PS Nanoplastics, NMNAT3, and Placental Ferroptosis
2026-09-10
This study identifies an NMNAT3-dependent metabolic cascade linking gestational polystyrene nanoplastic exposure to placental NAD+ depletion, mitochondrial dysfunction, ferritinophagy, ferroptosis, and fetal growth restriction. Its integrated metabolomics, cellular rescue, and nicotinamide-intervention strategy provides a mechanistic framework for investigating nanoplastic-induced reproductive toxicity and potential metabolic countermeasures.

Light-Inducible RNA Release for Regulated Gene Therapy
2026-09-09
A 2026 Trends in Biotechnology study presents a rationally designed light-inducible RNA-releasing protein (LIRP) that controls therapeutic protein production at the translation stage. By combining LIRP with AAV delivery and light-accessible tissues, the authors demonstrate reversible regulation in models of obesity and retinal neovascular disease, offering a safety-oriented framework for on-demand gene therapy.

Renal OCT2/MATE1 Inhibition by 5-HT3 Antagonists
2026-09-09
George and colleagues compared five 5-HT3 antagonist drugs in complementary cellular models of renal organic cation transport. Their results identify transporter-specific inhibition patterns and show that several agents, including tropisetron, can reduce OCT2/MATE1-dependent secretion in vitro, supporting further investigation of cationic drug interactions.

Cycloastragenol in Glucocorticoid-Induced Osteonecrosis
2026-09-08
A 2024 in vivo study shows that cycloastragenol reduced femoral-head necrosis and trabecular bone loss in a methylprednisolone-induced rat model of glucocorticoid-induced osteonecrosis of the femoral head. By combining micro-CT, angiography, histology, qPCR, and Western blotting, the study links structural preservation to reduced osteoclast activity and altered RANKL–OPG signaling, while leaving important translational questions unresolved.

Serine/Glycine-Free Diet and PD-L1 Lactylation
2026-09-08
The Cell Metabolism study by Tong et al. shows that a serine/glycine-free diet can inhibit colorectal cancer growth and increase cytotoxic T-cell activity, while simultaneously promoting immune evasion through PD-L1 lactylation. Its preclinical and early clinical findings support combining metabolic dietary intervention with immune checkpoint blockade, but randomized efficacy studies and more detailed clinical validation remain necessary.
