Bioassays and Inactivation of Prions [PDF]

, 2017
The experimental study of prions requires a model for their propagation. However, because prions lack nucleic acids, the simple techniques used to replicate bacteria and viruses are not applicable.

CCL26‐Mediated Modulation of Endothelial Secretome by Hypoxia‐Induced Tumor‐Derived Exosomes Enhances Metastatic Progression in Head and Neck Cancer

Head &Neck, EarlyView.
ABSTRACT Background Tumor cells adapt to hypoxia by releasing hiTDExs enriched with bioactive molecules that modulate endothelial behavior and promote tumor progression. This study aimed to characterize how hypoxia‐induced HNSCC exosomes reshape the endothelial secretome and contribute to metastatic potential.

Mode‐of‐Action and Human Relevance Assessment for Diisononyl Phthalate‐Induced Liver Tumors in Rodents

Journal of Applied Toxicology, EarlyView.
ABSTRACT Diisononyl phthalate (DINP) is a high molecular weight phthalate and high production volume chemical. DINP's carcinogenic potential has been investigated in four rodent bioassays, with liver tumors observed in three of the studies. Authoritative assessments have hypothesized that DINP acts through the peroxisome proliferator‐activated receptor

The TRPM2–PARP‐1 Axis Involvement in Bisphenol A and Nonylphenol‐Induced Ferroptosis in Trigeminal Ganglion Cells

Journal of Applied Toxicology, EarlyView.
ABSTRACT Environmental contaminants like bisphenol A (BPA) and nonylphenol (NP) are recognized neurotoxicants; however, the molecular mechanisms underlying their impact on sensory ganglia, specifically the trigeminal ganglion (TG), remain critically underexplored.
