Ambulatory blood pressure is better associated with target organ damage than clinic blood pressure in patients with primary glomerular disease.

Background: Blood pressure is an important and modifiable cardiovascular risk factor. Ambulatory blood pressure monitoring (ABPM) provides valuable prognostic information in patients with chronic kidney disease (CKD), yet little is known about the association of various types of BP measurements with target organ damage (TOD) in patients with primary glomerular disease. The goal of this study was to investigate whether ambulatory blood pressure is better associated with TOD than clinic blood pressure in patients with primary glomerular disease.

Activation of the Nrf2-ARE Pathway Ameliorates Hyperglycemia-Mediated Mitochondrial Dysfunction in Podocytes Partly Through Sirt1.

Background/aims: Previously we have shown that activation of the nuclear factor (erythroid-derived 2)-like 2 (Nrf2)-antioxidant response element (ARE) attenuated hyperglycemia-induced damage in podocytes, but the molecular mechanism remains unknown.

Methods: Tert-butylhydroquinone (t-BHQ) and small interfering RNAs (siRNAs) were used to regulate Nrf2 expression, while nicotinamide and siRNAs were used to regulate sirtuin 1 (Sirt1) activity and expression, respectively. Mitochondrial superoxide, membrane potential and ATP levels were measured to assess changes in mitochondrial function.
