Role of the aryl hydrocarbon receptor in tobacco smoke extract–induced matrix metalloproteinase‐1 expression

Abstract excerpt

Findings from large epidemiologic studies indicate that there is a link between smoking and extrinsic skin ageing. We previously reported that matrix metalloproteinases (MMPs) mediate connective tissue damage in skin exposed to tobacco smoke extracts. Tobacco smoke contains more than 3800 constituents, including numerous water-insoluble polycyclic aromatic hydrocarbons (PAHs) that trigger aryl hydrocarbon...
