Dual inhibition of the endothelin and angiotensin receptor ameliorates renal and inner ear pathologies in Alport mice

Project description:Alport syndrome, a type IV collagen disorder, leads to glomerular disease and, in some patients, hearing loss. AS is treated with inhibitors of the renin-angiotensin system; however, a need exists for novel therapies, especially those addressing both major pathologies. Sparsentan is a single-molecule dual endothelin type-A and angiotensin II type 1 receptor antagonist (DEARA) under clinical development for focal segmental glomerulosclerosis and IgA nephropathy. We report the ability of sparsentan to ameliorate both renal and inner ear pathologies in an autosomal-recessive Alport mouse model. Sparsentan significantly delayed onset of glomerulosclerosis, interstitial fibrosis, proteinuria, and glomerular filtration rate decline. Sparsentan attenuated glomerular basement membrane defects, blunted mesangial filopodial invasion into the glomerular capillaries, increased lifespan more than losartan, and lessened changes in profibrotic/proinflammatory genes pathways in both the glomerular and renal cortical compartments. Notably, treatment with sparsentan, but not losartan, prevented accumulation of extracellular matrix in the strial capillary basement membranes in the inner ear and reduced susceptibility to hearing loss. Improvements in lifespan and in renal and strial pathology were observed even when sparsentan was initiated after development of renal pathologies. These findings suggest that sparsentan may address both renal and hearing pathologies in Alport syndrome patients.

Characterization of a robust mouse model for heart failure with preserved ejection fraction

Project description:Heart failure with preserved ejection fraction (HFpEF) is a clinical syndrome with multisystem organ dysfunction in which patients develop symptoms of HF as the result of high left ventricular (LV) diastolic pressure Continuous infusion of angiotensin II and phenylephrine (AngII/PE) demonstrates a strong HFpEF phenotype RNAseq data demonstrate activation of pathways leading to myocardial metabolic changes, activation of ECM deposition, microvascular rarefaction, and pressure and volume related myocardial stress

Transcriptomics of cardiac biopsies reveals differences in patients with or without diagnostic parameters for heart failure with preserved ejection fraction

Project description:Heart failure affects 2–3% of adult Western population. Prevalence of heart failure with preserved left ventricular (LV) ejection fraction (HFpEF) increases. Studies suggest HFpEF patients to have altered myocardial structure and functional changes such as incomplete relaxation and increased cardiac stiffness. We hypothesised that patients undergoing elective coronary bypass surgery (CABG) with HFpEF characteristics will show distinctive gene expression compared to patients with normal LV physiology. Myocardial biopsies for mRNA expression analysis were obtained from sixteen patients with LV ejection fraction ≥ 45%. Five out of 16 patients (31%) had echocardiographic characteristics and increased NTproBNP levels indicative of HFpEF and this group was used as HFpEF proxy, while 11 patients had Normal LV physiology. Utilising principal component analysis, the gene expression data clustered into two groups, corresponding to HFpEF proxy and Normal physiology, and 743 differentially expressed genes were identified. The associated top biological functions were cardiac muscle contraction, oxidative phosphorylation, cellular remodelling and matrix organisation. Our results also indicate that upstream regulatory events, including inhibition of transcription factors STAT4, SRF and TP53, and activation of transcription repressors HEY2 and KDM5A, could provide explanatory mechanisms to observed gene expression differences and ultimately cardiac dysfunction in the HFpEF proxy group. <br> Sequencing data from clinical patients fall under GDPR regulations of sharing of personal data and will be made available through EGA-SE.

RNA-sequencing of epicardial adipose tissue of heart failure patients with preserved ejection fraction

Project description:Recent studies have suggested that epicardial adipose tissue (EAT) play an important role in the pathogenesis of heart failure with preserved ejection fraction (HFpEF), but few have characterized the underlying mechanism between their interactions. Recent evidence suggested that molecules secreted from EAT, including exosomes carrying non-coding RNAs (ncRNAs), may participate in the development of HFpEF. The aim of the present study was to investigate the expression profile of mRNAs and ncRNAs in EAT with HFpEF.

Circulating microRNAs are candidate markers of heart failure and differentiate between heart failure with reduced vs preserved left ventricular ejection fraction.

Project description:In this study, we compared the expression profiles of circulating miRNAs in blood samples from controls and patients with heart ailment. Subject with no past history of heart failure/disease are considered as controls. The patients were classified according to the percentage of left ventricular ejection fraction. Patients were grouped as heart failure with reduced (hfREF) and preserved (hfPEF) left ventricular ejection fraction. Employing miRNA microarray, we identified 'signature miRNAs' in peripheral blood samples that distinguished Heart failure from the non-heart failure controls, as well as those of hfREF and hfPEF groups.
