What does the aryl hydrocarbon receptor do?
The aryl hydrocarbon receptor (AhR) is a ligand-activated transcription factor present in many cells. The AhR links environmental chemical stimuli with adaptive responses, such as detoxification, cellular homoeostasis or immune responses.
Where are aryl hydrocarbon receptors?
Protein domains found in the aryl hydrocarbon receptor (AHR) and aryl hydrocarbon receptor nuclear translocator (ARNT). The nuclear localization sequence (NLS) and nuclear export sequence (NES) are found within the basic helix loop helix (bHLH) region. The bHLH also plays a critical role in DNA binding.
Is Tapinarof a biologic?
Abstract. Tapinarof (GSK2894512) is a naturally derived topical treatment with demonstrated efficacy for patients with psoriasis and atopic dermatitis, although the biologic target and mechanism of action had been unknown.
What is the connection of the aryl hydrocarbon receptor AhR and dioxin?
The dioxin/aryl hydrocarbon receptor (AhR) functions as a ligand-activated transcription factor regulating transcription of a battery of genes encoding xenobiotic metabolizing enzymes. Known receptor ligands are environmental pollutants including polycyclic aromatic hydrocarbons and polychlorinated dioxins.
What is the AIP gene?
AIP (Aryl Hydrocarbon Receptor Interacting Protein) is the name of the gene which causes pituitary adenomas in some families with acromegaly and occasionally prolactinomas, and very rarely with other types of pituitary adenomas.
Is Tapinarof FDA approved?
FDA Approves Dermavant’s VTAMA® (tapinarof) cream, 1% for the Treatment of Plaque Psoriasis in Adults: First Topical Novel Chemical Entity Launched for Psoriasis in the U.S. in 25 Years.
When will Tapinarof be available?
Jefferies sees tapinarof revenue this year hitting $10 million at the high end, should it launch around mid-2022, and ramping up to $50 million in 2023 for its psoriasis label.
What is AhR and dioxin?
What are AhR ligands?
AhR Ligands. The aryl hydrocarbon receptor (AhR) is a ligand-dependent transcriptional factor able to sense a wide range of structurally different exogenous and endogenous molecules. AhR ligands vary in their structure, and their binding affinity can significantly differ between mouse and human AhR [1].
Where is the APC gene located?
The human APC gene is located on the long (q) arm of chromosome 5 in band q22. 2 (5q22.
What happens when APC gene is mutated?
People with mutations in the APC gene have familial adenomatous polyposis (FAP) or attenuated FAP (AFAP). You have an increased chance to develop multiple gastrointestinal polyps, colorectal cancer, and possibly other cancers. There are risk management options to detect cancer early or lower the risk to develop cancer.
What does aryl mean?
Definition of aryl : having or being a monovalent organic radical (such as phenyl) derived from an aromatic hydrocarbon by the removal of one hydrogen atom —often used in combination.

Who makes Tapinarof?
Dermavant Sciences announced that VTAMA® (tapinarof) cream, 1%, an aryl hydrocarbon receptor agonist, indicated for the topical treatment of plaque psoriasis in adults, has been approved by the U.S. Food and Drug Administration (FDA).
Where is Ahr expressed?
Ahr is expressed in barrier tissues (e.g., the gut, the skin, and the lung) by both immune cells such as lymphocytes and tissue structural cells such as epithelial and stromal cells and in the liver by hepatocytes, consistent with its role as a sensor for environmental stimuli.
What causes APC?
Familial adenomatous polyposis (FAP) is a rare, inherited condition caused by a defect in the adenomatous polyposis coli (APC) gene. Most people inherit the gene from a parent. But for 25 to 30 percent of people, the genetic mutation occurs spontaneously.
