Tetraethylammonium Chloride: Mechanistic Assay Guide
2026-09-02
Tetraethylammonium chloride (TEAC) is more than a generic potassium-channel inhibitor: its pore-blocking behavior can help distinguish direct ion-conduction effects from downstream physiology. This guide connects TEAC assay design with classic β-cell electrophysiology, vascular research, and practical interpretation of channel experiments.

CLCC1 and Herpesvirus Nuclear Egress Fusion
2026-09-01
The reference preprint identifies the host protein CLCC1 as a required factor for the membrane-fusion step of herpesvirus nuclear egress, separating this process from the better-characterized viral budding stage. Its combination of a whole-genome CRISPR screen, infection phenotyping, and nuclear-pore analysis links viral capsid transport to an ancient cellular membrane-remodeling mechanism.

Gestational Polystyrene Nano-plastics Impair Male Fertility
2026-09-01
This 2026 Environment International study integrates testicular transcriptomics, serum metabolomics, histopathology, and adverse outcome pathway reasoning to examine how gestational polystyrene nano-plastics exposure compromises reproduction in adult male offspring. Its partial-AOP model links lipid and oxidative disturbances with cellular injury, testicular dysfunction, and abnormal spermatogenesis, while also identifying experimental priorities for validating intergenerational toxicity mechanisms.

KIR2.1 Inhibition in Pulmonary Vascular Remodeling
2026-08-31
The reference study identifies KIR2.1 as a functional regulator of pulmonary artery smooth muscle cell proliferation and migration in pulmonary hypertension models. Using monocrotaline-induced disease, PDGF-BB stimulation, ML133 inhibition, and pathway blockade, the authors connect KIR2.1 activity with the TGF-β1/SMAD2/3 axis, osteopontin, and PCNA.

CLCC1 and Herpesvirus Nuclear Egress Fusion
2026-08-29
A bioRxiv study identifies the host protein CLCC1 as an essential factor in the membrane-fusion step of herpesvirus nuclear egress, a stage that had remained mechanistically unresolved. Combining a whole-genome CRISPR screen with cellular and virological analyses, the authors connect CLCC1 loss to perinuclear capsid accumulation, impaired nuclear pore complex insertion, and reduced viral production.

Shufeng Xingbi Therapy in Allergic Rhinitis Rats
2026-08-28
This preprint investigates how Shufeng Xingbi Therapy affects allergic rhinitis in rats by integrating nasal inflammation, Th1/Th2-associated signaling, intestinal microbiota, and short-chain fatty acids. Its main contribution is a host–microbiome framework suggesting that therapeutic benefit may involve reduced Th2-associated activity alongside microbiota and metabolite changes, although the pre-peer-review design requires cautious interpretation.

Small-Molecule Antagonists of Shh–Heparin Binding
2026-08-27
Lamson and colleagues screened 34,560 compounds to identify small molecules that disrupt Sonic hedgehog N-terminal fragment binding to heparin, yielding 26 confirmed antagonists and two compounds with selective cellular activity. The study establishes Shh–heparin engagement as a tractable ligand-level target and shows how SAG can distinguish ligand inhibition from downstream Smoothened blockade.

3D Shell MEAs Map Cardiac Organoid Electrophysiology
2026-08-26
Choi and colleagues developed shape-adaptive shell microelectrode arrays that conform to cardiac organoids and record electrical activity across their three-dimensional surfaces. The platform combines 3D activation mapping, conduction-velocity analysis, calcium imaging, and pharmacological challenges to support more realistic cardiac electrophysiology research and drug-response assessment.

Pol II Degradation and Transcription-Independent Cell Death
2026-08-26
The preprint by Lee and colleagues argues that degradation of RNA polymerase II can activate cell death through a mechanism that is not explained solely by the loss of transcription. Its central contribution is a causal framework for separating transcriptional shutdown from the consequences of physically removing a core transcription complex, with implications for interpreting proteostasis, stress, and cancer biology experiments.
