PPAR-γ agonist, pioglitazone, reduced oxidative and endoplasmic reticulum stress associated with L-NAME-induced hypertension in rats

Publication date: Available online 12 November 2019Source: Life SciencesAuthor(s): Eman Soliman, Shereen F. Behairy, Nabila N. El-maraghy, Shimaa M. ElshazlyAbstractPeroxisome proliferator-activated receptor γ (PPAR-γ) agonist, pioglitazone, is used clinically to improve the glycemic state in patients with type-2 diabetes mellitus. Independent of its blood glucose-lowering properties, pioglitazone ameliorates different cardiovascular disorders. The aim of the present study was to investigate the effect of pioglitazone on cardiovascular complications of N-nitro-L-arginine methyl ester (L-NAME)-induced hypertension and to determine the role of oxidative and endoplasmic reticulum (ER) stress in its activity. Nitric oxide (NO) deficiency induced by chronic L-NAME administration was associated with high blood pressure (BP) and cardiac hypertrophy. L-NAME induced oxidative stress as indicated by reduced glutathione (GSH) levels, superoxide dismutase (SOD) and catalase activities as well as increased malondialdehyde (MDA) levels. Furthermore, L-NAME increased the expression of ER stress markers, activating transcription factor-4 (ATF-4) and C/EPBα-homologous protein-10 (CHOP-10) in both heart and aorta of hypertensive rats. Activation of PPAR-γ by pioglitazone reduced BP, restored the blunted NO levels, increased endothelial NO synthase (eNOS) expression, and restored the antioxidant status of L-NAME-induced hypertensive rats. Moreover, the antihypertensive a...

AbstractCardiovascular diseases (CVD) are one of the leading causes of death worldwide. Testosterone (T) is an important sex hormone that triggers several genomic and non-genomic pathways, leading to improvements of several cardiovascular risk factors and quality of life in men. At the vascular level, the key effect of T is the vasorelaxation. This review discusses the molecular pathways and clinical implications of T in the vascular system. Firstly, the mechanisms involved in the T vasodilator effect will be presented. Then, it will be discussed the association of T with the main risks for CVD, namely metabolic syndrome, ...

Authors: Arya DS, Chowdhury S, Chawla R, Das AK, Ganie MA, Kumar KMP, Nadkar MY, Rajput R Abstract Pharmacotherapy with fixed dose combination (FDC) drugs is becoming popular as evidence-based clinical guidelines recommend using multiple therapeutic agents in complex regimens for many chronic diseases including type 2 diabetes mellitus (T2DM). FDC formulations have unique advantages such as complementary mechanism of action, synergistic effects, better tolerability, elongated product life-cycle management, and cost savings. Polypharmacy is a frequent problem in T2DM patients having hypertension, dyslipidemia, and o...

The objective of this study was to determine the association of Computed tomography quantified visceral (VAT) and subcutaneous adipose tissue (SAT) with estimated glomerular filtration rate (eGFR) using CKD-EPI formula, diabetes mellitus, body mass index (BMI), proteinuria, lipid profile, and hypertension. Increased adipose tissue is the primary phenotypic characteristic of obesity. The amount and distribution of adipose tissue is associated with many adverse consequences, as hypertension, type 2 diabetes, cardiovascular disease etc. Abdominal CT with semi-automated software can quantify adipose tissue and predict the risk...

Authors: Wang Y, Koh WP, Sim X, Yuan JM, Pan A Abstract BACKGROUND: Multiple biomarkers have performed well in predicting type 2 diabetes mellitus (T2DM) risk in Western populations. However, evidence is scarce among Asian populations. METHODS: Plasma triglyceride-to-high density lipoprotein (TG-to-HDL) ratio, alanine transaminase (ALT), high-sensitivity C-reactive protein (hs-CRP), ferritin, adiponectin, fetuin-A, and retinol-binding protein 4 were measured in 485 T2DM cases and 485 age-and-sex matched controls nested within the prospective Singapore Chinese Health Study cohort. Participants were free of T2DM ...
