Isotretinoin (C0022265)

Definition (NCI) A naturally-occurring retinoic acid with potential antineoplastic activity. Isotretinoin binds to and activates nuclear retinoic acid receptors (RARs); activated RARs serve as transcription factors that promote cell differentiation and apoptosis. This agent also exhibits immunomodulatory and anti-inflammatory responses and inhibits ornithine decarboxylase, thereby decreasing polyamine synthesis and keratinization.
Definition (NCI) A drug that is used in the treatment of acne and psoriasis and is being studied in cancer prevention. It is a type of retinoid.
Definition (CSP) a topical dermatologic agent that is used in the treatment of acne vulgaris and several other skin diseases.
Definition (PDQ) A naturally-occurring retinoic acid with potential antineoplastic activity and teratogenic properties. 13-cis retinoic acid binds to and activates nuclear retinoic acid receptors (RAR), thereby regulating cell proliferation and differentiation. This agent also exhibits immunomodulatory and anti-inflammatory responses and inhibits ornithine decarboxylase, thereby decreasing polyamine synthesis and keratinization.
