Biotin (Vitamin B7) for Motor-Protein Assays
2026-08-28
Use Biotin (Vitamin B7) as a controlled metabolic supplement, avidin-binding reference, and quality-control component in protein-labeling workflows. Applied to BicD–MAP7–kinesin experiments, it helps separate motor activation from surface capture and highlights when free biotin should—and should not—be added.

MMAE and Tumor Plasticity: A Mechanistic Guide
2026-08-28
Monomethyl auristatin E (MMAE) is more than a high-potency cytotoxic payload: its activity can expose how tumor cell state influences antibody-drug conjugate response. This guide connects MMAE assay design with mechanistic insights from EBV-associated nasopharyngeal carcinoma research while clearly separating established evidence from translational hypotheses.

Nanoparticle Uptake by Human Cornea Cells
2026-08-24
The 2024 ACS Biomaterials Science & Engineering study by Azadi and David separates nanoparticle size and surface chemistry as determinants of uptake by human corneal epithelial cells. Its in vitro mucosal model and inhibitor-based analysis indicate that energy-dependent endocytosis, particularly macropinocytosis and caveolae-mediated uptake, dominates across the tested PLGA nanoparticle designs.

METTL16–SENP3–LTF Axis in HCC Ferroptosis
2026-08-24
Wang et al. identify a METTL16–SENP3–LTF signaling axis that links m6A-dependent RNA regulation to iron handling and ferroptosis resistance in hepatocellular carcinoma. The findings suggest that disrupting this axis could increase tumor sensitivity to ferroptotic stress, although validation in additional disease contexts and treatment models remains necessary.

AIBP-LRP2 Restricts CXCR4+ Collateral Growth
2026-08-22
The reference study identifies an AIBP-LRP2–HDL–miR-223 pathway that limits expansion of CXCR4+ stemlike capillary endothelial cells during ischemic remodeling. Its two-phase model links capillary expansion to later arterialization and suggests that disrupting this axis could improve collateral circulation in peripheral artery disease.
