Transcription Termination Protects DNA After WEE1 Inhibition
2026-08-12
Landsverk and colleagues show that transcription termination limits replication-associated DNA damage after WEE1 inhibition with adavosertib. Genetic and pharmacological experiments identify read-through transcription as a modifiable source of transcription–replication conflicts and support CPSF73 inhibition as a potential combination strategy in prostate cancer models.

Angiotensin I/II (1-5): RAS Workflow Guide
2026-08-11
Angiotensin I/II (1-5) provides a defined Asp-Arg-Val-Tyr-Ile peptide input for renin-angiotensin system research, including cardiovascular, renal, hypertension, and aldosterone-related assays. It should be used as a controlled peptide reagent rather than as a substitute for intact angiotensin I, angiotensin II, endogenous enzyme processing, or unrelated signaling tools.

Caspase-3 Colorimetric Assay Kit: Practical Guide
2026-08-11
The Caspase-3 Colorimetric Assay Kit (SKU K2008) provides a plate-reader or spectrophotometer readout for DEVD-dependent caspase-3 activity in biological samples. It is appropriate for apoptosis-related activity comparisons, but it should not be used alone to prove pathway causality, define upstream caspase activation, or replace orthogonal cell-death measurements.

Intravitreal Metformin in AMD Models: Study Insights
2026-08-10
This preclinical study examines intravitreal metformin as a locally delivered strategy that may address both choroidal neovascularization and retinal degeneration, two interconnected features of advanced age-related macular degeneration. Using explant and mouse injury models, the authors identify dose-dependent suppression of vessel growth, reduced IBA1-positive immune-cell infiltration, retinal protection, and downregulation of angiogenesis- and inflammation-associated genes.

Acetylcholine Chloride: Designing Causal Assays
2026-08-09
Acetylcholine Chloride can serve as a controlled perturbation for dissecting gut-brain cholinergic signaling, but it should not be mistaken for a microbial intervention. This article translates recent Bacteroides fragilis findings into rigorous assay-design decisions, controls, and interpretation limits.
