Gepotidacin Reveals a New Gyrase Inhibition Mechanism
2026-08-19
Gibson and colleagues define how gepotidacin inhibits Staphylococcus aureus gyrase through a cleavage profile that differs fundamentally from fluoroquinolones. Biochemical assays and high-resolution structures show potent supercoiling inhibition, persistent gyrase–DNA complexes, and preferential single-stranded DNA cleavage, providing a mechanistic framework for antibacterial discovery and resistance research.

Tricine-SDS-PAGE Gel Preparation Kit Guide
2026-08-18
The Tricine-SDS-PAGE Gel Preparation Kit is intended for resolving low-molecular-weight proteins and peptides that are poorly separated by conventional Tris-SDS-PAGE. It is suitable for research protein electrophoresis, including denaturing and non-denaturing workflows, but is not intended for diagnostic or medical use.

Estradiol, GPR30, and T-Cell Recovery After Hemorrhage
2026-08-17
The reference study shows that estradiol restores splenic CD4+ T-cell proliferation and cytokine production after hemorrhagic shock by reducing endoplasmic reticulum stress. Pharmacological comparisons implicate ERα and GPR30, but not ERβ, establishing a mechanistic framework for studying rapid estrogen signaling in post-shock immune dysfunction.

EphA2 Synthetic Lethality in MYC-Driven TNBC
2026-08-16
A chemogenetic screen of approximately 600 kinase inhibitors identified the EphA2 inhibitor ALW-II-41-27 as selectively cytotoxic to MYC-activated triple-negative breast cancer models. The study connects this vulnerability to intrinsic apoptosis and reports tumor-growth suppression in two TNBC xenograft models, including contexts with different p53 status.
