    TLDR Minoxidil can reduce functions related to androgen receptors.
    The 2014 study investigated the effects of Minoxidil, a common treatment for androgenetic alopecia (AGA), on androgen receptor (AR)-related functions. Contrary to previous studies, the researchers found that Minoxidil does affect AR-related functions. Specifically, Minoxidil was found to suppress AR transactivation, target gene expression, and the growth of androgen-sensitive prostate cancer cells. It also interfered with peptide-AR interactions and disrupted AR N- and C-terminal interactions, which are necessary for full transcriptional activity of the AR. Furthermore, Minoxidil was found to decrease AR stability. The study concluded that Minoxidil can suppress AR-related functions, including AR transcription and AR-related cell growth, suggesting that the mechanism of action of Minoxidil may include a decrease in AR stability.
