Natural phenylethanoid glycoside forsythoside A alleviates androgenetic alopecia by selectively inhibiting TRPV3 channels in mice.

Eur J Pharmacol

January 2025

Department of Pharmacology, School of Pharmacy, Qingdao Medical College of Qingdao University, Qingdao, China; Institute of Innovative Drugs, Qingdao University, Qingdao, China.

Dihydrotestosterone (DHT), an androgen derivate, is known to be a key factor involved in androgenetic alopecia. DHT suppresses the growth of outer root sheath cells and induces apoptosis of hair keratinocytes, thereby causing hair follicle miniaturization and hair regrowth inhibition. Forsythoside A, a natural substance derived from Forsythia suspensa, has been shown to reduce DHT-induced apoptosis in human hair cells and suppress hair regrowth inhibition induced by DHT in mice.

Human-induced global warming, primarily attributed to the rise in atmospheric CO, poses a substantial risk to the survival of humanity. While most research focuses on predicting annual CO emissions, which are crucial for setting long-term emission mitigation targets, the precise prediction of daily CO emissions is equally vital for setting short-term targets. This study examines the performance of 14 models in predicting daily CO emissions data from 1/1/2022 to 30/9/2023 across the top four polluting regions (China, India, the USA, and the EU27&UK).
