Intracellular regulation of matrix metalloproteinase-2 activity: the roles of caveolin-1 and troponin I phosphorylation
DownloadFall 2010
Matrix metalloproteinase‐2 (MMP‐2) was recently revealed to have targets and actions within the cardiac myocyte. In ischemia/reperfusion (I/R) injury, MMP‐2 is activated and degrades troponin I (TnI) and α‐actinin. The regulation of intracellular MMP‐2 activity is relatively unknown and is thus...

Thrombotic microangiopathy (TMA) is a broad term for a range of diseases that usually manifest with rapid failure of the affected organ. Although different in etiology, these diseases share a common pattern of injury originating in the vascular endothelium. In turn, the injured vasculature...

Investigating the role of G-protein coupled receptor (GPCR) signaling as a potential target for anti-angiogenic therapy
DownloadFall 2021
Angiogenesis is an essential process for normal growth and development whereby new blood vessels are formed from pre-existing ones. The balance between pro-angiogenic and anti-angiogenic growth factors is critical to maintain normal physiological condition. Prolonged activation of angiogenesis...

Technological advances for treatment of congenital heart disease (CHD) have led to decreases in mortality over the past thirty years. Persistent morbidity into adolescence and adulthood necessitates regular medical follow-up and the influence of ongoing physical health issues on the teens...

The heart requires an uninterrupted supply of fuels to sustain its physiological function. Fatty acids are the predominant substrates and endogenous triglyceride turnover contributes significantly to fatty acid oxidation. Lipins are cytosolic, bifunctional enzymes involved in both glycerolipid...

Cardiac Fatty acids β-oxidation (FAO) markedly increases during maturation and become the major source of energy for the adult heart. However, excessive rates of FAO can compromise cardiac function in obesity, diabetes, and heart failure. Lysine acetylation has recently been identified as a...

Cardiovascular disease (CVD) is the leading cause of morbidity and mortality worldwide, while ischemic heart disease (IHD) dominates the cause of CVD mortality. Following myocardial infarction (MI), the heart experiences a series of structural and functional changes, termed post-infarction...

Access to health care should be determined by clinical need and not by age. Older people form an increasing proportion of the general population and of those with coronary heart disease, but compared with younger people they are less likely to be invited for cardiac rehabilitation programmes and...

The traditional PI3K pathway relies on agonist mediated stimulation of PI3Kα through RTKs and PI3Kγ through GPCRs, which stimulate downstream enzymes such as Akt. This pathway has been found to be important in cardiomyocytes and cardiofibroblasts for regulating cardiac morphology and function....

Heart disease is a leading cause of morbidity and mortality in the world with a growing prevalence in a variety of manifestations. Many of the events that occur in the heart during the progression of disease have been explored to identify a causative mechanism to develop effective treatments and...
