Are Mitochondrial Fusion and Fission Impaired in Leukocytes of Type 2 Diabetic Patients?

2016

Mitochondrial fusion/fission alterations have been evaluated in different tissues of type 2 diabetic (T2D) patients. However, it is not known whether mitochondrial dynamics is disturbed in the leukocytes of T2D patients and whether glycemic control affects its regulation. Anthropometric and metabolic parameters in 91 T2D patients (48 with glycated hemoglobin [HbA1c]6.5% and 43 with HbA1c6.5%) were characteristic of the disease when compared with 78 control subjects. We observed increased reactive oxygen species production in leukocytes from diabetic patients, together with a reduced mitochondrial oxygen consumption rate, especially in poorly controlled patients. Mitochondrial fusion was red…

Insulin Resistance in PCOS Patients Enhances Oxidative Stress and Leukocyte Adhesion: Role of Myeloperoxidase

2016

Cardiovascular diseases and oxidative stress are related to polycystic ovary syndrome (PCOS) and insulin resistance (IR). We have evaluated the relationship between myeloperoxidase (MPO) and leukocyte activation in PCOS patients according to homeostatic model assessment of IR (HOMA-IR), and have explored a possible correlation between these factors and endocrine and inflammatory parameters. This was a prospective controlled study conducted in an academic medical center. The study population consisted of 101 PCOS subjects and 105 control subjects. We divided PCOS subjects into PCOS non-IR (HOMA-IR2.5). Metabolic and anthropometric parameters, total and mitochondrial reactive oxygen species (…

The mitochondria-targeted antioxidant MitoQ modulates oxidative stress, inflammation and leukocyte-endothelium interactions in leukocytes isolated fr…

2016

It is not known if the mitochondria-targeted antioxidants such as mitoquinone (MitoQ) can modulate oxidative stress and leukocyte-endothelium interactions in T2D patients. We aimed to evaluate the beneficial effect of MitoQ on oxidative stress parameters and leukocyte-endothelium interactions in leukocytes of T2D patients. The study population consisted of 98 T2D patients and 71 control subjects. We assessed metabolic and anthropometric parameters, mitochondrial reactive oxygen species (ROS) production, glutathione peroxidase 1 (GPX-1), NFκB-p65, TNFα and leukocyte-endothelium interactions. Diabetic patients exhibited higher weight, BMI, waist circumference, SBP, DBP, glucose, insulin, HOMA…
