research Development of a Liquid Chromatography/Mass Spectrometry-Based Inhibition Assay for the Screening of Steroid 5-α Reductase in Human and Fish Cell Lines
A new method was created to test the effectiveness of Dihydrotestosterone (DHT) inhibitors, like finasteride and dutasteride, in human and fish cells. The results showed fish cells are more sensitive to these treatments, and dutasteride works better than finasteride in all tested cells.
research Markers of peripheral androgen action in vivo and in vitro
Dihydrotestosterone (DHT) is crucial for conditions like male-pattern baldness and acne, and measuring a byproduct, androstanediol glucuronide, is a better way to assess DHT's effects than DHT blood levels.
