Cy5 amine (non-sulfonated): Protocol Guide
2026-09-28
Cy5 amine (non-sulfonated), SKU A8143, is a primary-amine cyanine reagent for covalent labeling through activated esters, carbodiimide-activated carboxy groups, or epoxides. It is suitable for controlled mixed-solvent workflows but insoluble in water, so it should not be added as a direct aqueous labeling reagent or used for diagnostic or medical applications.

Locust PLK1 Links Midgut Health and Molting
2026-09-28
The study characterizes Polo-like kinase 1 in the migratory locust and reports that LmPLK1 knockdown damages the midgut, disrupts molting-associated processes, and increases susceptibility to malathion. Partial rescue by 20-hydroxyecdysone (20E) supports a connection between LmPLK1 and endocrine regulation, while leaving the precise molecular steps to be established.

Nuclear cGAS Limits LINE-1 Retrotransposition
2026-09-27
This study identifies a nuclear function for cGAS: it limits LINE-1 retrotransposition by helping the E3 ligase TRIM41 ubiquitinate and degrade the essential L1 protein ORF2p. The findings connect DNA-damage signaling through CHK2 to control of a mobile genetic element, while highlighting a distinct mechanism from cGAS’s canonical cytosolic innate-immune activity.

MAPK10, KRT16, and NSCLC Metastasis
2026-09-22
This study identifies MAPK10 as a metastasis-suppressive kinase that phosphorylates KRT16, promoting RNF213-dependent ubiquitination and proteasomal degradation. The findings connect MAPK10 activity with reduced NSCLC invasion, favorable prognosis, and a potentially actionable MAPK10/KRT16/RNF213 regulatory axis.

RGFP966: HDAC3 Mechanism and HO-1 Context
2026-09-22
RGFP966 is a pharmacological HDAC3 inhibitor with evidence from memory-formation studies, whereas AMC-Hem is a fluorescent probe for heme oxygenase-1 activity. The available evidence does not establish that RGFP966 directly changes HO-1 activity, so the two reagents should be used as separate experimental tools.

Digoxin Inhibits HIF-1α in Thyroid Eye Disease
2026-09-21
A 2026 Biochemical and Biophysical Research Communications study identifies HIF-1α as a mechanistic link between hypoxia, inflammation, fibrosis, STAT3 signaling, and GSDME-mediated pyroptosis in thyroid eye disease. In primary orbital fibroblast models, low-nanomolar Digoxin reversed several of these responses, supporting pharmacological HIF-1α inhibition as a research direction while leaving important translational questions unresolved.
