17β-Estradiol and ICI-182780 Regulate the Hair Follicle Cycle in Mice Through an Estrogen Receptor-α Pathway
TLDR Estradiol stops hair growth in mice, but an antagonist can reverse this effect.
The study investigated the effects of 17β-estradiol and ICI-182780 on the hair follicle cycle in mice, focusing on the estrogen receptor-α pathway. Researchers found that 17β-estradiol prolonged the telogen (resting) phase of the hair cycle, while ICI-182780, an estrogen receptor antagonist, shortened it. These findings suggested that estrogen receptor-α played a significant role in regulating hair follicle cycling, with potential implications for understanding hair growth and alopecia.
