March 2026 in “The Journal of Steroid Biochemistry and Molecular Biology” This study found that mice lacking both vitamin D and calcium-sensing receptors in epidermal keratinocytes are predisposed to developing squamous cell carcinoma as they age, due to impaired oxidative stress response and reduced DNA repair capabilities.

January 2020 in “The journal of investigative dermatology/Journal of investigative dermatology” This study found that epidermolysis bullosa simplex keratinocytes had impaired mitochondrial activity and more dispersed mitochondrial distribution compared to normal human keratinocytes.
March 2013 in “Molecular & Cellular Toxicology/Molecular & cellular toxicology” In this study, exposure to m-Aminophenol in human keratinocytes altered the expression of thousands of genes involved in inflammation and stress responses, suggesting potential biomarkers for MAP-induced skin toxicity.

January 2024 in “iScience” The researchers reported that stress-induced keratins in human skin are expressed at lower levels than those in healthy skin and are co-regulated with genes involved in differentiation, inflammation, and immunity, rather than replacing keratins of normal differentiation or indicating cell proliferation.
