Special Issue Information

Dear Colleagues,

Since the initial discovery of microRNAs’ specific biological functions in the late 1990s, our understanding of these unique RNA molecules in both health and disease has grown exponentially. The impact of miRNA biology continues to be wide-reaching and often surprising—particularly in the field of cardiovascular physiology. Beyond the canonical functions of individual microRNAs that affect their isolated gene targets and downstream pathophenotypes, developing concepts in cardiovascular biology include the study of paracrine or endocrine functions of extracellular forms of microRNAs, an increasing appreciation for the complexity of regulation of microRNAs via other non-coding RNA molecules, and a growing interest in understanding the "network-based" pleiotropy of microRNAs through a combination of computational and experimental methods.

This special issue will provide an open access opportunity for publishing research work and review articles related to cardiovascular biology and disease, and to offer comprehensive new insights into the current and future directions of this exciting and important research field.

Submission

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. Papers will be published continuously (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are refereed through a peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Cells is an international peer-reviewed Open Access quarterly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 500 CHF (Swiss Francs). English correction and/or formatting fees of 250 CHF (Swiss Francs) will be charged in certain cases for those articles accepted for publication that require extensive additional formatting and/or English corrections.

Abstract: The importance of microRNAs, for maintaining stability in the developing vertebrate heart has recently become apparent. In addition, there is a growing appreciation for the significance of microRNAs in developmental pathology, including for congenital heart defects. We examined the expression of microRNAs in right ventricular (RV) myocardium from infants with idiopathic tetralogy of Fallot (TOF, without a 22q11.2 deletion) and found 61 microRNAs to be significantly changed in expression in myocardium from children with TOF compared to normally developing comparison subjects (O’Brien et al. 2012). The pattern of miRNA expression in TOF myocardium had a surprising resemblance to expression patterns in fetal myocardium. Predicted targets of microRNAs with altered expression were enriched for gene networks that regulate cardiac development. We derived a list of 229 genes known to be critical to heart development and found 44 had significantly changed expression in TOF myocardium relative to normally developing myocardium. These 44 genes had significant negative correlation with 33 microRNAs, each of which also had significantly changed expression. Here, we focus on miR-421 as it is significantly up regulated in RV tissue from infants with TOF; is predicted to interact with multiple members of cardiovascular regulatory pathways; and has been shown to regulate cell proliferation. We knocked down and overexpressed miR-421 in primary cells derived from RV from infants with TOF and infants with normally developing hearts, respectively. We found a negative correlation between the expression of miR-421 and several key genes in the WNT and Notch pathways. These finding suggest that the dysregulation of miR-421 in the developing human heart may contribute to tetralogy of Fallot and warrants further investigation.

Tentative Title: miRNAs as regulators of regulators: the complex knots of the homeobox transcription factor Pitx2

Abstract: The homeobox transcription factor Pitx2 plays a relevant role during early embryogenesis, as part of the left-right signaling cascade and more recently, a pivotal role for this transcription factor has been reported in cardiac and skeletal muscle development and disease. Pitx2 is dynamically expressed during embryogenesis and three distinct alternative spliced variants have been reported; Pitx2a, Pitx2b and Pitx2c. Although all Pitx2 isoforms are expressed during early gastrulation, Pitx2c is the most abundant isoform during muscle organogenesis. Over the last years we have gained insights into the transcriptional regulatory mechanisms driven by Pitx2 in both cardiac and skeletal muscle. Interestingly, besides playing a role in regulating a large number of protein-coding genes, microRNAs have also been reported to be regulated by Pitx2. In this review, we will summarize current state of-the-art knowledge about the regulatory mechanisms controlling Pitx2-microRNA interactions, and their link to muscle diseases and we will provide novel insights into microRNA-mediated regulatory networks controlling Pitx2 and their implication for therapeutics.
