January 2012 in “Biological & pharmaceutical bulletin” This study found that the protein hairless acts as both a corepressor and coactivator of the vitamin D receptor, influencing gene transcription in a ligand-selective manner.
April 2016 in “Journal of Investigative Dermatology” This study found that inhibiting JAK signaling can unexpectedly trigger hair growth in resting-phase mouse skin, implicating JAK-STAT pathways and oncostatin M in maintaining hair follicle stem cell quiescence.
April 2016 in “Journal of Investigative Dermatology” This study suggests that dsRNA may enhance KRT9 expression in palm and sole skin through β-catenin signaling, potentially linking mechanical damage to specific skin features and certain skin conditions.
April 2026 in “bioRxiv (Cold Spring Harbor Laboratory)” In this study, periodic exposure to red light in aged mice led to increased histone acetylation and activated mitochondrial fatty acid oxidation, which collectively mitigated cellular aging by modulating metabolism, inflammation, and gene expression.
