Amiloride (MK-870): Ion Transport Evidence
2026-08-27
Amiloride (MK-870) is an epithelial sodium channel probe supplied as BA2768 for mechanistic ion transport research. In a grass carp reovirus entry study, amiloride did not inhibit infection under the tested conditions, demonstrating why cellular endocytosis modulation requires pathway-specific controls.

HCN4 Heat Sensing and Heart Rate Control
2026-08-26
This bioRxiv preprint identifies an M407/Y409 motif in the S4–S5 linker of HCN4 as a determinant of heat-induced pacemaker current and heart-rate acceleration. By combining modeling, mutagenesis, isolated sinoatrial-node assays, and mouse genetics, the study connects thermal sensing to both HCN4 gating and cAMP-dependent cardiac modulation.

Aneugen Mechanisms Revealed by a 27-Chemical Assay
2026-08-24
Bernacki and colleagues describe a tiered flow-cytometric strategy that moves beyond detecting genotoxicity to identifying whether aneugenic chemicals act through tubulin stabilization, tubulin destabilization, or mitotic kinase inhibition. The study shows how fluorescent Taxol responses, mitotic phospho-histone H3, Ki-67, and machine learning can support mechanism-oriented genotoxicity profiling.
