Cardiac mast cells cause atrial fibrillation through PDGF-A-mediated fibrosis in pressure-overloaded mouse hearts.
Atrial fibrillation (AF) is a common arrhythmia that increases the risk of stroke and heart failure. Here, we have shown that mast cells, key mediators of allergic and immune responses, are critically involved in AF pathogenesis in stressed mouse hearts. Pressure overload induced mast cell infiltration and fibrosis in the atrium and enhanced AF susceptibility following atrial burst stimulation....
متن کاملSignaling pathway-focused gene expression profiling in pressure overloaded hearts.
The β-blocker propranolol displays antihypertrophic and antifibrotic properties in the heart subjected to pressure overload. Yet the underlying mechanisms responsible for these important effects remain to be completely understood. The purpose of this study was to determine signaling pathway-focused gene expression profile associated with the antihypertrophic action of propranolol in pressure ov...
متن کاملMetabolomic analysis of pressure-overloaded and infarcted mouse hearts.
BACKGROUND Cardiac hypertrophy and heart failure are associated with metabolic dysregulation and a state of chronic energy deficiency. Although several disparate changes in individual metabolic pathways have been described, there has been no global assessment of metabolomic changes in hypertrophic and failing hearts in vivo. Hence, we investigated the impact of pressure overload and infarction ...
متن کاملRecruitment of NADH shuttling in pressure-overloaded and hypertrophic rat hearts.
Glucose metabolism in the heart requires oxidation of cytosolic NADH from glycolysis. This study examines shuttling reducing equivalents from the cytosol to the mitochondria via the activity and expression of the oxoglutarate-malate carrier (OMC) in rat hearts subjected to 2 wk (Hyp2, n = 6) and 10 wk (Hyp10, n = 8) of pressure overload hypertrophy vs. that of sham-operated rats (Sham2, n = 6; ...
متن کاملMyosin isozyme synthesis and mRNA levels in pressure-overloaded rabbit hearts.
The in vivo synthesis rates of myosin isozyme heavy chains beta and alpha were measured in right ventricular (RV) muscle at 2 and 4 days following pulmonary artery constriction in rabbits, together with measurements of their relative mRNA levels. The synthesis rate of beta-myosin heavy chains was elevated in 2-day (0.27 +/- 0.06 day-1 or 2.5 +/- 0.7 mg/g RV/day, mean +/- SD) and in 4-day (0.25 ...
