Plasma heme oxygenase-1 is decreased in peripheral artery disease patients.
Peripheral artery disease (PAD) is a common manifestation of atherosclerosis. A number of emerging risk factors, including oxidative stress biomarkers, free radicals and heat shock proteins, may add to the established risk factors for cardiovascular disease (CVD). The present study assessed surrogate markers of oxidative stress, including total reduced glutathione (GSH), lipid hydroperoxides (LOOH), isoprostanes, heme oxygenase‑1 (HO‑1) and metabolic biomarkers, such as adiponectin and lactate, in PAD patients (n=27). Healthy age‑matched volunteers (n=27) served as controls. GSH and LOOH were evaluated by measuring total thiol groups and iron oxidation, respectively, by spectrophotometric a…
Circulating miR-130a, miR-27b, and miR-210 in Patients With Peripheral Artery Disease and Their Potential Relationship With Oxidative Stress: A Pilot Study
Some emerging risk factors such as oxidative stress biomarkers and microRNAs (miRs) may add additional value to the established risk factors for peripheral artery disease (PAD). We enrolled 27 patients with PAD and 27 age-matched controls. We examined the levels of a series of miRs (miR-130a, miR-27b, and miR-210) in serum samples. The level of well-established oxidative stress biomarkers, such as lipid hydroperoxides, isoprostanes, hemeoxygenase-1 (HO-1) and reduced glutathione, was also measured in plasma and their relationship with the miRs was determined. Levels of miR-130a, miR-27b, and miR-210 were significantly increased in patients with PAD when compared to the controls. The level …
