Phloretin cytoprotection and toxicity

Chemico-Biological Interactions, 2018
Phloretin (Phl) is a dihydrochalcone flavonoid with significant cytoprotective properties; e.g., free radical trapping, electrophile scavenging. Based on this, it has been suggested that Phl might be useful in the treatment of pathogenic processes and prevention of drug toxicities.

Deconstruction of Human Age‐Related Cataract Capsules Defines Aging

Advanced Science, EarlyView.
We generate a comprehensive atlas of age‐related cataracts (ARC) at a single‐cell resolution, encompassing three disease states—mild cataract group (Mild), severe cortical cataract group (Severe_C), and severe nuclear cataract group (Severe_N). We find that ARC involves seven distinct lens capsule cell types, with notable differences in cellular ...

Gastrointestinal Cytoprotection by PPAR Ligands [PDF]

PPAR Research, 2010
Peroxisome proliferator-activated receptor (PPAR) is a nuclear receptor that is known to play a central role in lipid metabolism and insulin sensitivity as well as inflammation and cell proliferation. According to the results obtained from studies on several animal models of gastrointestinal inflammation, PPAR has been implicated in the regulation of ...
