TRAIN-HEART Network

The TRAIN-HEART consortium, funded by the European Commission (2019-2023), is made up to train a league of 15 promising fellows that harness novel insights in the pathogenesis of ischemic heart failure, study the therapeutic potential of existing RNA therapeutics and improve its efficacy by the design of novel drug delivery systems.


People

TRAIN-HEART brings together leading academic teams and (biotech) companies covering various disciplines ranging from fundamental research to clinical pharmacology and gene therapy to drug delivery applications, have teamed up in the European Union.


Research Programme

The TRAIN-HEART network aims to gain viable insight in the pathogenesis of ischemic heart failure which will serve as a basis for drug discovery and drug delivery efforts that aim to therapeutically target specific molecules and mechanisms within cardiomyocytes for the treatment of ischemic heart failure.

The long non-coding RNA NRON promotes the development of cardiac hypertrophyin the murine heart

Article abstract:

Physiological and pathological cardiovascular processes are tightly regulated by several cellular mechanisms. Non-coding RNAs, including long non-coding RNAs (lncRNAs), represent one important class of molecules involved in regulatory processes within the cell. The lncRNA Non-coding repressor of NFAT (NRON) was described as a repressor of nuclear factor of activated T cells (NFAT) in different in vitro studies. Although the calcineurin/NFAT-signaling pathway is one of the most important pathways in pathological cardiac hypertrophy, a potential regulation of hypertrophy by NRON in vivo has remained unclear. Applying subcellular fractionation and RNA-FISH, we found that, unlike what is known from T cells, in cardiomyocytes NRON predominantly localizes to the nucleus. Hypertrophic stimulation in neonatal mouse cardiomyocytes led to a downregulation of NRON, while NRON overexpression led to an increased in expression of hypertrophic markers. To functionally investigate NRON in vivo, they used a mouse model of transverse aortic constriction (TAC)-induced hypertrophy and performed NRON gain- and loss-of-function experiments.
