The enzyme CD73 helps control human hair growth and could be targeted to treat hair growth disorders.
research AN ATTEMPT TO ASSESS THE MAGNITUDE OF ENDOGENOUS ANDROGEN PRODUCTION IN A CASE OF THE ADRENOGENITAL SYNDROME*
A 17-year-old female with adrenogenital syndrome produces very high levels of androgens, which prevent complete feminization despite high estrogen doses.
research Treatment with and withdrawal from finasteride alter ethanol intake patterns in male C57BL/6J mice: Potential role of endogenous neurosteroids?
Finasteride affects alcohol intake in male mice, possibly due to neurosteroids.
research Coat condition, housing condition and measurement of faecal cortisol metabolites - a non-invasive study about alopecia in captive rhesus macaques (Macaca mulatta)
Alopecia in captive rhesus macaques is affected by season, sex, age, housing, and stress, with complex links between stress hormones and hair loss.
research Endogenous retinoids in the hair follicle and sebaceous gland
Maintaining the right amount of retinoic acid is crucial for healthy hair and skin.
