Consequences Of 2,3,7,8-Tetrachlorodibenzo-P-Dioxin (Tcdd) On Hepatic Stellate Cell Activation And Extracellular Matrix Remodeling During Chronic Liver Injury, Cheri Lou Lamb
Boise State University Theses and Dissertations
2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD) is a persistent environmental pollutant and high-affinity ligand for the aryl hydrocarbon receptor (AhR). Exposure to TCDD elicits a spectrum of toxic effects, many involving aberrant cell proliferation, activation, and differentiation. The liver is a target organ for TCDD toxicity, and increasing evidence indicates that AhR signaling regulates genes that coordinate deposition and remodeling of the extracellular matrix (ECM) in the liver. Hepatic stellate cells (HSCs) are central to ECM remodeling in the liver. We recently reported that TCDD treatment increases the activation of human HSCs in vitro. The goal of this study was to …
