TLDR Dihydrotestosterone (DHT) increases oil production in skin cells by activating mTOR, and mTOR inhibitors can reduce this effect.
The study demonstrated that dihydrotestosterone (DHT) induced lipid synthesis and storage in androgen-sensitive sebocytes through the activation of the mTOR pathway, independent of AKT activation. The use of mTOR inhibitors, such as rapamycin and torin, inhibited lipid neosynthesis and storage in DHT-treated cells. Additionally, DHT was shown to decrease autophagic flow as a result of mTOR stimulation. These findings linked mTOR and autophagic processes to androgenic stimulation in sebaceous function and suggested the potential use of mTOR inhibitors to modulate androgen-dependent sebum overproduction.
