E cadherin appears to be an essential on/off switch for initiating bile canaliculi formation

The paper identifies E cadherin as essential for initiating bile canaliculi formation in hepatocytes through proteomic analysis and protein repression experiments.

Identification of uranyl-binding proteins in Arabidopsis thaliana cells exposed to uranium: Insights from a metalloproteomic analysis and characterization of Glycine-Rich RNA-binding Protein 7 (GRP7)

This study identifies 57 uranyl-binding proteins in Arabidopsis thaliana cells, with GRP7 showing specific U(VI) binding and interference with RNA binding, suggesting a role in uranium toxicity.

Beyond the ink: cellular and molecular effects of iron-based pigments on macrophages

The paper investigates the effects of red and black iron oxide pigments on macrophages, finding that red iron oxide causes mitochondrial dysfunction, oxidative stress, and pro-inflammatory cytokine secretion.

Biobased, Biodegradable but not bio-neutral: about the effects of polylactic acid nanoparticles on macrophages
