December 2024 in “Frontiers in Pharmacology” In this study, human cell models of hair follicles showed that araliadiol, a plant-derived polyacetylene compound, promotes hair growth through the p38/PPAR-γ signaling pathway, suggesting its potential as a new drug candidate for alopecia treatment.
September 2019 in “The journal of investigative dermatology/Journal of investigative dermatology” This study found that the PPARγ modulator NAC-GED-0507-Levo may protect hair follicles from chemotherapy-induced damage, potentially offering a strategy to address irreversible hair loss in cancer patients.
This study found that loss of the DNA methyltransferase Dnmt3a, but not Dnmt3b, increased carcinogen-induced squamous tumors in murine epidermis, with combined deletion leading to more aggressive and metastatic carcinomas.
The research found that while Dnmt3a and Dnmt3b are not necessary for skin homeostasis in mice, the loss of Dnmt3a increases squamous tumor formation from carcinogens, and combined deletion of both results in more aggressive and metastatic tumors.
May 2009 in “Faculty Opinions – Post-Publication Peer Review of the Biomedical Literature” This study suggests that decreased PPARgamma function may trigger the pathogenesis of lichen planopilaris, and PPARgamma-targeted therapy could be a potential treatment method.
