Phalloidin B7678: F-Actin Workflow Guide
2026-09-14
Phalloidin B7678 is a high-affinity F-actin probe for preserving and visualizing filament organization in fixed or permeabilized cells, tissue sections, and cell-free assays. Its filament-stabilizing activity makes it unsuitable for live-cell imaging, reversible actin studies, or direct measurement of native G-actin behavior.

p-Cresyl Metabolites and Biliary Epithelial Injury
2026-09-13
The reference study shows that the gut microbial metabolites p-cresyl sulfate and p-cresyl glucuronide promote apoptosis and inflammatory signaling in biliary epithelial cells. By combining a human cell model with mouse exposure experiments, it connects Clostridium-associated metabolite biology with hepatobiliary immune injury while identifying important limitations for translation to primary biliary cholangitis.

CRTC–CREB Senses Proteotoxic Stress in Drosophila
2026-09-12
The reference study identifies the CRTC–CREB transcriptional axis as a stress sensor that connects proteasome inhibition to ROS/JNK signaling and adaptive proteostasis programs. Using Drosophila, cultured cells, transcriptomics, and a Huntington’s disease model, the authors show that increasing CRTC/CREB activity can improve protein quality control and reduce aggregation-related phenotypes.

Isradipine (Dynacirc): L-Type Channel Logic
2026-09-11
Isradipine (Dynacirc) is more than a calcium-channel inhibitor: it is a tool for separating L-type calcium influx from broader calcium-dependent phenotypes. This guide uses neuronal channel-classification evidence to improve mechanistic interpretation in vascular, excitotoxicity, and neurodegenerative disease model research.

Carbapenemase Gene Transmission in CREC
2026-09-10
Chen et al. mapped carbapenemase-encoding genes in 54 carbapenem-resistant Enterobacter cloacae isolates from eight Guangdong teaching hospitals, combining gene localization, antimicrobial susceptibility, conjugation, mobile-element analysis, and ERIC-PCR typing. The study identifies plasmid-borne blaNDM-1 as a major transferable resistance determinant and provides a practical framework for interpreting both horizontal gene transfer and clonal dissemination in hospital surveillance.

Tivozanib (AV-951): VEGFR Assay Workflows
2026-09-10
Build sharper anti-angiogenic experiments with Tivozanib (AV-951), from VEGFR pathway readouts to renal cell carcinoma models. This workflow separates growth arrest from true cell killing, helping researchers interpret potency, selectivity, and combination effects more reliably.

PXR Activation Links Liver Regeneration to CYP Activity
2026-09-09
Bi et al. show that activating pregnane X receptor (PXR) in rats produces more than liver enlargement: it also increases the protein expression and in vivo metabolic activity of CYP3A1/2 and CYP2C6/11. The study provides an integrated view of hepatic regeneration and drug-metabolizing capacity, while highlighting important limits for translating rodent PXR findings to human pharmacology.

FH1 for iPS-Derived Hepatocyte Maturation
2026-09-09
FH1 supports functional maturation of iPS-derived hepatocyte-like cells by pairing stronger albumin output with higher CYP3A4 and lower AFP. This workflow shows how to use FH1 in hepatocyte culture, build orthogonal maturity readouts, and evaluate its potential as a foundation for controlled gene-expression assays.

IGFBP2–THBS1 Axis in Growth Hormone Therapy
2026-09-08
The reference study identifies an IGFBP2–THBS1 regulatory axis that links growth hormone treatment to IGF-1 pathway activation in idiopathic short stature-associated chondrocytes. Its combination of patient plasma analysis, bioinformatics, and gain- and loss-of-function experiments provides a mechanistic framework for interpreting variable responses to GH therapy and designing more focused growth-plate studies.

RNA Pol II Inhibition Activates Apoptosis
2026-09-07
Harper et al. show that RNA polymerase II inhibition kills cells through an active apoptotic signaling program rather than through passive depletion of transcripts and proteins. Their identification of the Pol II degradation-dependent apoptotic response (PDAR) provides a mechanistic framework for interpreting transcription-targeting drugs and designing cell-death experiments.

CTDNEP1–NEP1R1 Control of ER Lipid Homeostasis
2026-09-05
This study shows that NEP1R1 stabilizes CTDNEP1 to control lipin 1 and restrict endoplasmic reticulum expansion, while CTDNEP1 can regulate lipid droplet formation without the same regulatory-subunit dependence. Its structure–function and biochemical evidence supports a model in which ER membrane synthesis and lipid storage are differentially controlled.
