Assessing mitochondrial redox status by flow cytometric methods: vascular response to fluid shear stress.

Assessing mitochondrial redox status by flow cytometric methods: vascular response to fluid shear stress. Curr Protoc Cytom. 2011 Oct;Chapter 9:Unit9.37 Authors: Li R, Jen N, Yu F, Hsiai TK Abstract Mitochondria are an important source of superoxide production contributing to physiological and pathological responses, including vascular oxidative stress that is relevant to cardiovascular diseases. Vascular oxidative stress is intimately linked with pro-inflammatory states and atherosclerosis. Oxidized low-density lipoprotein (OxLDL) modulates intracellular redox status and induces apoptosis in endothelial cells. Hemodynamic, specifically, fluid shear stress imparts both biomechanical and metabolic effects on vasculature. Mitochondria are an important source of superoxide production contributing to vascular oxidative stress with relevance to cardiovascular diseases. We hereby present biophysical and biochemical approaches, including fluorescence-activated cell sorting, to assess the dynamics of vascular redox status. PMID: 21965108 [PubMed - indexed for MEDLINE]
