Excessive UV exposure contributes to many disorders, such as photoaging, skin inflammation, and carcinogenesis.Methods: To determine the effects of bamboo extract (BEX) from our local plant, Acidosasa longiligula, on UV-irritated human skin, we conducted a variety of studies, including Western blot, apoptosis assays, reactive oxygen species (ROS) detection, and thioredoxin (TXN) and thioredoxin reductase (TXNRD) activity assays in primary skin keratinocytes.Results: We first determined that BEX protects human skin keratinocytes against UV radiation-induced apoptosis and ROS production. UV radiation can robustly impair TXN and TXNRD activity which can, in turn, be significantly rescued by BEX treatment. Moreover, BEX regulates TXN1 levels in primary skin keratinocytes and TXN1 is proved to be required for the protective function of BEX. Last, we found that the NF-κB/p65 pathway mediates the protective function of BEX against UV.Discussion: Collectively, our work delineates the beneficial role of BEX in UV-induced skin cell damage and provides a novel therapeutic reagent to prevent or alleviate the progress of photoaging and other UV-provoked skin diseases.Keywords: Acidosasa longiligula, bamboo extract, BEX, ultraviolet radiation, UV radiation, thioredoxin, TXN, NF-κB pathwayHuang JXu QLin MCheng BJi CDove Medical Pressarticleacidosasa longiligulabamboo extract (bex)ultraviolet (uv) radiationthioredoxin (txn)nf-κb pathwayGeriatricsRC952-954.6ENClinical Interventions in Aging, Vol Volume 15, Pp 897-905 (2020) |
