All-trans retinoic acid induces cell-cycle arrest in human cutaneous squamous carcinoma cells by inhibiting the mitogen-activated protein kinase-activated protein 1 pathway. Effect of all-trans-retinoic acid on enterovirus 71 infection in vitro. This compound also induces expression of hedgehog (Hh) signaling receptor Patched 1, inhibiting Hh signaling.Ĭhen S, Yang Y, Xu J, et al. RA decreases cellular cholesterol and inhibits Mycobacterium in an NPC2-dependent manner. In cutaneous squamous cell carcinoma cells, RA induces G1 phase cell cycle arrest, increases expression of p21 and p27, decreases expression of cyclin D1/CDK4 and cyclin E/CDK2, and induces apoptosis. In subjects with APL, retinoic acid forces promyelocytes to differentiate into normal blood cells. This compound also induces expression of IFNα in cells infected with enterovirus 71, decreasing viral infectivity. In vivo, RA inhibits fibroblast proliferation and scar formation and decreases levels of TGF-β1, IL-6, and NF-κB. ![]() RA is a vitamin A carboxylic acid that is clinically used to treat acne vulgaris, keratosis pilaris, and acute promyelocytic leukemia (APL). Trans-retinoic acid (RA) is an activator of the retinoic acid receptor (RAR) that exhibits anti-fibrotic, antiviral, antibacterial, immunomodulatory, and anticancer chemotherapeutic activities. ![]()
