6C Culture Prolongs Mouse Corneal Epithelial Growth
2026-08-17
An et al. developed a serum-free, feeder-free 6C culture system that preserves mouse corneal epithelial cell proliferation and epithelial identity across ex vivo expansion. By combining six pathway-modulating small molecules with air-lift culture, the study improved cell yields, limited epithelial–mesenchymal transdifferentiation, and supported corneal epithelial repair in vivo.

Phosbind Biotin LC: PVDF Workflow Guide
2026-08-16
Phosbind Biotin LC is a phosphate-binding reagent for detecting phosphorylated proteins on PVDF membranes without relying on a sequence-matched phospho-specific antibody. It is suited to Western Blot phosphorylated protein detection with streptavidin-HRP and chemiluminescence, but not to aqueous-only workflows or long-term storage of working solutions.

AZD8055: Practical mTOR Inhibitor Workflow
2026-08-14
AZD8055 is a selective, ATP-competitive mTOR inhibitor for controlled studies of mTORC1 signaling, mTORC2 signaling, cancer cell proliferation, and metabolism. It is useful for mechanistic preclinical experiments but is not appropriate for water-based formulations or studies whose primary goal is clinical efficacy prediction.

iPSC Organoids Reveal Pan-Genotype HEV Tropism
2026-08-14
This 2025 Gut study establishes induced pluripotent stem cell-derived liver, intestinal and brain organoids that support the complete life cycle of clinical hepatitis E virus genotypes 1, 3 and 4. The models resolve tissue-specific viral tropism, injury responses and partial ribavirin sensitivity, creating a human-relevant platform for HEV pathogenesis and antiviral research.

Anp32e Drives Renal Interstitial Fibrosis via TGF-β
2026-08-13
This study identifies Anp32e as an active promoter of renal interstitial fibrosis rather than merely a fibrosis-associated marker. Using patient tissue, a unilateral ureteral obstruction model, and proximal tubular cells, the authors connect Anp32e to TGF-β1/Smad3 activation and show that pathway inhibition can reverse Anp32e-associated fibrotic protein deposition.

Cy5 NHS ester(Et): Practical Labeling Guide
2026-08-11
Cy5 NHS ester(Et) is a water-soluble reagent for covalently attaching fluorescent Cy5 groups to primary amines in proteins, peptides, and related biomolecules. It is suited to immediate-use protein fluorescent labeling, immunofluorescence staining, flow cytometry, and fluorescence microscopy workflows, but not to ethanol-based protocols or long-term storage of prepared solutions.

MEG3, TGF-β, and NiO NP Pulmonary Fibrosis
2026-08-10
The reference study identifies a mechanistic relationship between reduced lncRNA MEG3, elevated TGF-β1, PI3K/AKT activation, and collagen deposition after nickel oxide nanoparticle exposure. Its combination of rat pulmonary injury modeling, A549-cell experiments, pharmacological inhibition, and MEG3 overexpression supports MEG3 as a regulatory brake on nanoparticle-associated fibrotic signaling.
