More recently, androgen receptors have been shown to have a second mode of action. As has been also found for other steroid hormone receptors such as estrogen receptors , androgen receptors can have actions that are independent of their interactions with DNA. [13] [29] Androgen receptors interact with certain signal transduction proteins in the cytoplasm. Androgen binding to cytoplasmic androgen receptors can cause rapid changes in cell function independent of changes in gene transcription, such as changes in ion transport . Regulation of signal transduction pathways by cytoplasmic androgen receptors can indirectly lead to changes in gene transcription, for example, by leading to phosphorylation of other transcription factors.

Azelaic acid is used to treat mild to moderate acne, both comedonal acne and inflammatory acne. [6] [7] It belongs to a class of medication called dicarboxylic acids . It works by killing acne bacteria that infect skin pores. It also decreases the production of keratin, which is a natural substance that promotes the growth of acne bacteria. [8] Azelaic acid is also used as a topical gel treatment for rosacea , due to its ability to reduce inflammation. [7] It clears the bumps and swelling caused by rosacea. The mechanism of action is thought to be through the inhibition of hyperactive protease activity that converts cathelicidin into the antimicrobial skin peptide LL-37. [9] Azelaic acid has been used for treatment of skin pigmentation including melasma and postinflammatory hyperpigmentation , particularly in those with darker skin types. It has been recommended as an alternative to hydroquinone . [10] As a tyrosinase inhibitor, azelaic acid reduces synthesis of melanin . [11]
