Cardiac gene expression profiling of heart failure treatment with the anti-ischemic drug ranolazine

Project description:Heart failure is a leading cause of cardiovascular mortality with limited options for treatment. We analyzed whether the anti-ischemic drug ranolazine could retard the progression of heart failure in an experimental model of heart failure induced by 6 months of chronic pressure overload. The study showed that 2 months of ranolazine treatment improved cardiac function of aortic constricted C57BL/6J (B6) mice with symptoms of heart failure as assessed by echocardiography. The microarray gene expression study of heart tissue from failing hearts relative to ranolazine-treated and healthy control hearts identified heart failure-specific genes that were normalized during treatment with the anti-ischemic drug ranolazine. Microarray gene expression profiling was performed with heart tissue isolated from three study groups: (i) untreated 10 month-old C57BL/6J (B6) mice with heart failure induced by 6 months of abdominal aortic constriction (AAC), (ii) 10 month-old B6 mice with 6 months of AAC and two months of treatment with the anti-ischemic drug ranolazine (200 mg/kg), and (iii) age-matched, untreated, sham-operated B6 control mice.

Cardiac gene expression profiling of apoE-deficient mice receiving heart failure treatment with the anti-ischemic drug ranolazine

Project description:Heart failure is a leading cause of cardiovascular mortality with limited options for treatment. We used 18 month-old apolipoprotein E (apoE)- deficient mice as a model of atherosclerosis-induced heart failure to analyze whether the anti-ischemic drug ranolazine could retard the progression of heart failure. The study showed that 2 months of ranolazine treatment improved cardiac function of 18 month-old apoE-deficient mice with symptoms of heart failure as assessed by echocardiography. To identify changes in cardiac gene expression induced by treatment with ranolazine a microarray study was performed with heart tissue from failing hearts relative to ranolazine-treated and healthy control hearts. The microarray approach identified heart failure-specific genes that were normalized during treatment with the anti-ischemic drug ranolazine. Microarray gene expression profiling was performed with heart tissue isolated from (i) untreated 18 month-old apoE-deficient mice with heart failure relative to (ii) 18 month-old apoE-deficient mice treated for two months with the anti-ischemic drug ranolazine (200 mg/kg), and (iii) age-matched non-transgenic C57BL/6J (B6) control mice.

Transcriptome analysis of diabetic and non diabetic patients affected by post-ischemic heart failure

Project description:Increased morbidity and mortality associated with post-ischemic heart failure (HF) in diabetic patients underscore the need for a better understanding of the underlying molecular events. Indeed, effective HF therapy in diabetic patients requires a complex strategy encompassing the development of improved diagnostic and prognostic markers and innovative pharmacological approaches. Whole mRNAs expression was measured in the heart of patients with heart failure (HF) with or without concomitant Type 2 diabetes mellitus (T2DM) and compared it to control non-failing hearts. We identified distinct genes modulated in HF patients compared to controls, as well as to T2DM HF patients compared to not diabetic HF patients. Our study included left ventricle (LV) cardiac biopsies taken from the vital, non-infarcted zone (remote zone) derived from patients affected by dilated hypokinetic post-ischemic cardiomyopathy, undergoing surgical ventricular restoration procedure. Inclusion criteria for diabetic were: GLICEMIA: >=126 mg/dl, previous T2DM diagnosis or anti-diabetic therapy, while for non diabetic: GLICEMIA: <100 mg/dl and HbA1c: n.v. 4.8-6.0%. Moreover, HF patients were matched for End Systolic Volume (ESV), Ejection fraction (LVEF), Age, Sex, Ethnic distribution, Smoke habits, Hypertension, Glomerular filtration rate (GFR), Body Mass Index (BMI). Genes expression was assessed by Affymetrix GeneChips Human Gene 1.0 ST array, using total RNA extracted from 7 T2DM HF patients, 12 non-T2DM HF patients and 5 controls.
