Cardiomyopathies, a leading cause of mortality, are associated with dysfunctional intercalated discs, which connect neighbouring cardiomyocytes and ensure proper contractility. In human cardiac diseases, loss-of-function mutations of the intercalated disc-associated protein Nebulin-Related Anchoring Protein (NRAP) have been reported. NRAP plays a crucial role in myofibril assembly and mechanotransduction, however, its regulatory functions remain unclear.

Heart failure (HF) is a complex clinical syndrome marked by impaired contractility, adverse remodeling, and dysregulated intracellular signaling. Protein kinases are central regulators of cardiac function, modulating calcium handling, gene transcription, hypertrophy, and apoptosis through phosphorylation of target proteins. In HF, chronic activation of kinases such as protein kinase A, protein kinase C, calcium/calmodulin-dependent kinase II, mitogen-activated protein kinases, protein kinase B, and Rho-associated protein kinase contributes to progressive cardiac dysfunction.

Aims: Non-pharmacological therapies for acute decompensated heart failure (HF) and cardiogenic shock have evolved considerably in recent decades. Short-term mechanical circulatory support (MCS) devices can be used as circulatory backup. While nearly all available devices use continuous flow, evidence indicates that pulsatile flow can be more effective.

Objective: Pediatric pulmonary vein stenosis (PVS) is associated with substantial morbidity and mortality for the subset of patients with recurrent or progressive disease. The molecular mechanisms underlying the development and trajectory of PVS remain unclear. This study characterizes the transcriptome of clinical and phenotypic subtypes of PVS.

We compared the effects of ex-vivo machine perfusion (EVMP) of hearts donated after circulatory death (DCD) with the single-shot solutions HTK-N and Del Nido cardioplegia (DNC) on left-ventricular (LV) contractility and myocardial microcirculation. In a DCD pig model, hearts were maintained by EVMP with hypothermic, oxygenated HTK-N (DCD-HTK-N; N = 8) or DNC (DCD-DNC; N = 8) followed by reperfusion with blood, including assessment of contractility and microcirculation with Laser-Doppler-Flow (LDF). We performed transcriptomics using microarrays.
