Heart failurewith preservedejection fraction (HFPEF) is amajorcauseof morbidity and mortality and constitutes a significant portion of medical care costs. Being as deadly as systolic HF, it completely lacks effective therapy beside the management of its metabolic risk factors including diabetes, obesity and hyperlipidaemia, and hypertension. Typical medication that helps systolic HF (HF with re...

Metalloproteinases (MPs) play key roles in the responses of cells to their microenvironment. By effecting proteolytic degradation or activation of cell surface and extracellular matrix (ECM) proteins they can modulate both cell-cell and cell-ECM interactions, which influence cell differentiation, migration, proliferation and survival. Both secreted and membranebound forms of metalloproteinases ...

Pathologically activated fibroblasts have been shown to play a role in fibrotic disorders and cancer, but the molecular mechanisms regulating their emergence are still poorly characterized. A recent study demonstrates that unleashing metalloproteinase activity in fibroblasts is sufficient for the acquisition of an activated pro-tumorigenic phenotype. Stromal cells and extracellular matrix (ECM)...

Matrix metalloproteinases (MMPs) and tissue inhibitors of metalloproteinases (TIMPs) remodel the pericellular environment by regulating the cleavage of extracellular matrix proteins, cell surface components, neurotransmitter receptors, and growth factors, which together regulate cell adhesion, synaptogenesis, synaptic plasticity, and long-term potentiation. Increased MMP activity and dysregulat...

The consumption of alcohol causes several liver-associated diseases all over the world. Alcoholic liver diseases (ALD) include hepatic inflammation, fatty liver, hepatitis, liver cirrhosis and fibrosis and finally hepatocellular carcinoma. Although the cellular, metabolic and biochemical mechanisms for these diseases are quite explicable, the roles of matrix metalloproteinases (MMPs) and tissue...

Matrix metalloproteinases (MMPs) and tissue inhibitors of metalloproteinases (TIMPs) remodel the pericellular environment by regulating the cleavage of extracellular matrix proteins, cell surface components, neurotransmitter receptors, and growth factors that mediate cell adhesion, synaptogenesis, synaptic plasticity, and long-term potentiation. Interestingly, increased MMP activity and dysregu...

Matrix metalloproteinases (MMPs), also called matrixins, function in the extracellular environment of cells and degrade both matrix and non-matrix proteins. They play central roles in morphogenesis, wound healing, tissue repair and remodelling in response to injury, e.g. after myocardial infarction, and in progression of diseases such as atheroma, arthritis, cancer and chronic tissue ulcers. Th...

PURPOSE To determine the effect of latanoprost on the expression of human matrix metalloproteinases (MMPs) and tissue inhibitors of metalloproteinases (TIMPs) in the trabecular meshwork (TM). METHODS Total RNA was isolated, and qualitative RT-PCR was performed to detect the mRNA of MMPs and TIMPs in human TM tissue and explant cultures of TM endothelial cells. Cultures of TM cells were treate...
