March 2014 in “International Journal of Molecular Sciences” The study observed that testosterone reduced knee range of motion in ovariectomized female rats, potentially by downregulating specific relaxin receptor isoforms, with its effects mediated via dihydro-testosterone.
November 2024 in “EMJ Dermatology” In clinical studies, inhibiting androgen receptor expression using CosmeRNA ARI SAMiRNA micelles effectively treated androgenetic alopecia by significantly increasing hair growth, as reported in this research.
This research reported that AKR1C enzyme expression, particularly AKR1C4, in scalp sebaceous glands decreases with age, suggesting potential age-related changes in androgen metabolism affecting hair follicle health. Additionally, sulforaphane treatment increased AKR1C expression in related cell types.
In this study, researchers found that androgen receptor expression and AKR1C-mediated androgen inactivation, including AKR1C4, are prominent in scalp sebaceous glands, with AKR1C expression decreasing with age and differing by sex, suggesting these changes may impact hair follicle health as people age.
April 2026 in “Inflammation and Regeneration” This study found that androgen inactivation pathways in scalp sebaceous glands change with age, specifically noting that AKR1C expression, including AKR1C4 previously thought liver-specific, declines with age and is sex dependent, which could impact hair follicle health during aging.
