June 1979 in “Proceedings of the National Academy of Sciences” This study demonstrated that keratin is widely present in various epithelial cells, providing structural strength and potential insights into the origin of cell lines.
June 2026 in “International Journal of Molecular Sciences” This study found that shallot (Allium ascalonicum) extracts reduced oxidative stress in human nasal epithelial cells caused by PAH exposure by decreasing ROS generation, suppressing lipid peroxidation, and restoring SOD activity, with quercetin being a key antioxidant component.
