Aryl Hydrocarbon Receptor and Stem Cells
From the biochemical point of view, the aryl hydrocarbon receptor (AHR) is a highly conserved, developmentally regulated, and ligand-activated member of the bHLH/PAS family of transcription factors. The AHR was originally discovered because of the human and animal toxicity of its most potent and persistent ligand, 2,3,7,8-tetrachlorodibenzo-pdioxin, usually just referred to as “dioxin.” The can...
متن کاملBreast Cancer Stem-Like Cells Are Inhibited by a Non-Toxic Aryl Hydrocarbon Receptor Agonist
BACKGROUND Cancer stem cells (CSCs) have increased resistance to cancer chemotherapy. They can be enriched as drug-surviving CSCs (D-CSCs) by growth with chemotherapeutic drugs, and/or by sorting of cells expressing CSC markers such as aldehyde dehydrogenase-1 (ALDH). CSCs form colonies in agar, mammospheres in low-adherence cultures, and tumors following xenotransplantation in Scid mice. We hy...
متن کاملAryl hydrocarbon receptor and lung cancer.
The leading cause of lung cancer is exposure to cigarette smoke and other environmental pollutants, which include formaldehyde, acrolein, benzene, dioxin, and polycyclic aromatic hydrocarbons (PAHs). PAHs and dioxins are exogenous ligands that directly bind to the aryl hydrocarbon receptor (AhR), a transcription factor that activates xenobiotic metabolism, histone modification (an important ste...
متن کاملThe Aryl Hydrocarbon Receptor and Tumor Immunity
The aryl hydrocarbon receptor (AhR) is an important cytosolic, ligand-dependent transcription factor. Emerging evidence suggests the promoting role of the AhR in the initiation, promotion, progression, invasion, and metastasis of cancer cells. Studies on various tumor types and tumor cell lines have shown high AhR expression, suggesting that AhR is activated constitutively in tumors and facilit...
