The microenvironment of native heart tissue may be better replicated when cardiomyocytes are cultured in three-dimensional clusters (i.e., spheroids) than in monolayers or as individual cells. Thus, we differentiated human, cardiac-lineage, …

Mitochondrial dysfunction elicits various stress responses in different model systems, but how these responses relate to each other and contribute to mitochondrial disease has remained unclear. Mitochondrial myopathy (MM) is the most common manifestation …

Although targeted therapies are often effective systemically, they fail to adequately control brain metastases. In preclinical models of breast cancer that faithfully recapitulate the disparate clinical responses in these microenvironments, we observed …

The oncoprotein Mdm2 is a RING domain–containing E3 ubiquitin ligase that ubiquitinates G protein–coupled receptor kinase 2 (GRK2) and β-arrestin2, thereby regulating β-adrenergic receptor (βAR) signaling and endocytosis. Previous studies showed that …

Our data suggest that, after a myocardial infarction, integrin-associated protein CD47 on cardiac myocytes is elevated. In culture, increased CD47 on the surface of dying cardiomyocytes impairs phagocytic removal by immune cell macrophages. After …

Objective To examine the role of miR-124a in LPS- induced septic cardiac insufficiency where underlying mechanism is unclear. Results Expression of miR-124a was decreased in myocardium of LPS-induced septic cardiac dysfunc- tion model. miR-124a antagomiR …

Aims Luma is a recently discovered, evolutionarily conserved protein expressed in mammalian heart that is associated with the LInker of Nucleoskeleton and Cytoskeleton (LINC) complex. The LINC complex structurally integrates the nucleus and the cytoplasm, …

Ventricular chamber growth and development during perinatal circulatory transition is critical for functional adaptation of the heart. However, the chamber-specific programs of neonatal heart growth are poorly understood. We used integrated systems …

The olm (Proteus anguinus) is a troglomorphic, neotenous amphibian with extraordinary life expectancy and unique adaptations that deserve further investigation. A low reproductive rate and habitat decline render it threatened by extinction. Establishing …
