asymmetric siRNA androgen receptor androgenetic alopecia small interfering RNA AR gene cell-penetrating asiRNA cp-asiAR DHT dihydrotestosterone intradermal injection AR mRNA AR protein hair growth hair follicle ex vivo human scalp tissues primary human dermal papilla cells interleukin-6 transforming growth factor-β1 dickkopf-1 siRNA AR AGA hair loss hair regrowth scalp tissues dermal papilla cells
Studysummary This study found that intradermal injection of a specially designed RNA molecule, cp-asiAR, successfully reduced androgen receptor levels and promoted hair growth in a mouse model of androgenetic alopecia, while also improving hair follicle characteristics in ex vivo human scalp tissues without significant toxicity.
