Carbapenemase Gene Spread in CREC Hospitals
2026-09-01
Chen and colleagues combined gene localization, antimicrobial susceptibility testing, conjugation assays, mobile-element analysis, and ERIC-PCR typing to examine carbapenem-resistant Enterobacter cloacae across eight teaching hospitals in Guangdong. The findings emphasize plasmid-associated blaNDM-1, efficient laboratory transfer of carbapenemase-encoding genes, and genetically related isolates distributed across departments and hospitals.

ZK53 Activates ClpP in Lung Squamous Cancer
2026-09-01
The reference study identifies ZK53 as a selective activator of human mitochondrial ClpP and shows that excessive ClpP activity disrupts respiratory-chain proteostasis in lung squamous cell carcinoma. By connecting mitochondrial ATP loss with E2F-target suppression, ATM-mediated DNA damage response signaling, and cell-cycle arrest, the work establishes a mechanistic framework for targeting mitochondrial quality control in LUSC.

Gut Microbial H2S Suppresses GLP-1 in Male Mice
2026-08-31
The reference study identifies Desulfovibrio-derived hydrogen sulfide as a gut-to-host metabolic signal that suppresses GLP-1 production in male mice. By linking microbial H2S to impaired mitochondrial respiration and the unfolded protein response in intestinal L cells, the work provides a mechanistic framework for how dysbiosis may contribute to metabolic syndrome and shows that bismuth subsalicylate can improve metabolic outcomes in the tested models.

hiPSC Intestinal Organoids for Pharmacokinetic Studies
2026-08-31
Saito and colleagues developed a direct three-dimensional culture strategy for generating expandable intestinal organoids from human induced pluripotent stem cells. The organoids could be propagated, cryopreserved, and converted into epithelial monolayers containing enterocytes with cytochrome P450 and transporter activities, creating a more human-relevant platform for pharmacokinetic studies.

Lipo3K Transfection Reagent for PTX-Resistance Studies
2026-08-30
Use Lipo3K Transfection Reagent to build reproducible DNA, siRNA, mRNA, and co-transfection workflows in resistant breast cancer models. Its low-toxicity cationic lipid chemistry is particularly useful when transporter perturbation, drug accumulation, and cell viability must be measured in the same experiment.

Cefazedone–Etimicin PK by UFLC–MS/MS
2026-08-28
The reference study developed and validated a rapid UFLC–MS/MS assay for simultaneous measurement of cefazedone and etimicin in beagle dog plasma. Its application to intravenous dosing found no obvious pharmacokinetic difference between combination treatment and either antibiotic administered alone, providing a useful analytical basis for evaluating coadministration.

Annexin V-FITC/7-AAD Apoptosis Kit Guide
2026-08-26
The Annexin V-FITC/7-AAD Apoptosis Kit provides a rapid dual-fluorescence method for separating viable, early apoptotic, and membrane-compromised cell populations in cell viability and cytotoxicity workflows. It is intended for intact cells analyzed by fluorescence microscopy or flow cytometry, not as a standalone proof of apoptotic mechanism or a clinical diagnostic test.

Resazurin Sodium Salt in iPSC-CF Testing
2026-08-25
Patient-derived iPSC airway models are making cystic fibrosis drug testing more genotype-aware, but translational decisions require both disease-specific functional measurements and robust cell-state controls. This article positions Resazurin sodium salt as a complementary redox-based readout for viability, metabolic activity, assay quality, and screening scalability—not as a substitute for direct CFTR function assays.
