March 2015 in “Cell death and differentiation” This study found that H-Ras activation in aged mouse skin leads to increased dysplasia and progression to in situ squamous cell carcinoma, highlighting an age-linked connection between immune changes, senescence, and cancer risk.
December 2012 in “Journal of Dermatological Science” This study found that activating Wnt/beta-catenin signaling in hair follicles is sufficient to induce adipocyte generation in the dermis, affecting both hair follicle stem cell activation and adipocyte differentiation.
