The role of PRMT1-mediated alternative splicing in dilated cardiomyopathy

(University of Tsukuba) In a study published in iScience, Professor Akiyoshi Fukamizu of the Life Science Center for Survival Dynamics, Tsukuba Advanced Research Alliance (University of Tsukuba, JAPAN) and the research group reported a new work on discovery of the important role of PRMT1 in dilated cardiomyopathy (DCM).

AbstractAimsThe alarmin S100A8/S100A9 (S100A8/A9) is released by activated monocytes/macrophages and neutrophils in the setting lymphocytic myocarditis (MC). We recently demonstrated its therapeutic potential in experimental acute MC. Now, we investigated the diagnostic relevance of S100A8/A9 serum levels in patients with suspected acute and chronic MC and in patients with heart failure without cardiac inflammation.Methods and ResultsSerum S100A8/A9 levels were analysed in patients with a recent onset of MC [ ≤ 30 days,n = 32; ejection fraction (EF): 45.4 ± 12.9%], dilated cardiomyopathy ...

Authors: Samejima Y, Iuchi A, Kanai T, Noda Y, Nasu S, Tanaka A, Morishita N, Suzuki H, Okamoto N, Harada H, Ezumi A, Ueda K, Kawahara K, Hirashima T Abstract Cardiac side effects associated with immune checkpoint inhibitors (ICIs) are an uncommon but serious complication with a relatively high mortality. We experienced a case of cardiomyopathy induced by nivolumab. Echocardiography showed diffuse hypo-kinesis of the left ventricular cardiac wall and a significant decrease in the ejection fraction, like dilated cardiomyopathy. The myocardial biopsy showed non-inflammatory change; cardiac function gradually improved...

AbstractBackgroundContemporary survival trends of Dilated Cardiomyopathy (DCM) patients are largely unknown. The aims of this study are to describe clinical descriptors, survival trends and the prognostic impact of etiological characterization in DCM patients.MethodsDCM patients were consecutively enrolled and divided into 4 groups according to the period of enrolment: 1st: 1978 ‐1984; 2nd: 1985 ‐1994; 3rd: 1995 ‐2004; 4th: 2005 ‐2015. A cohort of patients with DCM with specific etiology, enrolled from 2005 to 2015, was also analyzed.ResultsOver a mean follow ‐up of 12±8 years, 1284 DCM patients (52...

In this study, we constructed a high specific and efficient serum biomarker discovery pipeline. We utilized dysregulated proteins identified in primary tissue and potentially secreted into the blood as biomarker candidates. The scheduled multiple reaction monitoring method was performed to accurately quantify and verify these candidates directly in serum, thus circumventing the effects of high-abundance proteins. We then generated new variables through assigning values to protein-protein correlations to extend the dimensionality of the dataset (PPC-VDE), and the specificity of disease classification. We successfully applie...

ConclusionsThe conformational auto ‐epitope targeted by cardio‐pathogenic β1‐receptor autoantibodies is faithfully conserved in cyclopeptide homologues of the β1ECII loop bearing the NDPK211 –214 motif and the C209↔C215 bridge while lacking cysteine C216. Such molecules provide promising tools for novel diagnostic and therapeutic approaches in β1‐autoantibody‐positive CHF.

Conclusions: We herein present a comprehensive single-cell landscape of the cardiac immune cells in different EAM phases. In addition, we elucidated the contribution of Hif1a to the inflammatory response through the regulation of immune cell activity, particularly of macrophage cluster 2 and Th17 cells. Moreover, a Hif1a inhibitor alleviated inflammatory cell infiltration of the EAM model and may serve as a potential therapeutic target in the clinic.
