Complement factor H (fH) is a plasma protein that regulates activation of the alternative pathway, and mutations in fH are associated with a rare form of thrombotic microangiopathy (TMA), known as atypical hemolytic uremic syndrome (aHUS). A more common TMA is thrombotic thrombocytopenic purpura, which is caused by the lack of normal ADAMTS-13-mediated cleavage of von Willebrand factor (VWF). W...

In the present study, we tried to examine whether oleanolic acid regulates the activity, secretion and gene expression of matrix metalloproteinase-3 (MMP-3) in primary cultured rabbit articular chondrocytes, as well as the production of MMP-3 in the knee joint of rat to evaluate the potential chondroprotective effect of oleanolic acid. Rabbit articular chondrocytes were cultured in a monolayer,...

We examined whether apigenin affects the gene expression, secretion and activity of matrix metalloproteinase-3 (MMP-3) in primary cultured rabbit articular chondrocytes, as well as in vivo production of MMP-3 in the knee joint of rat to evaluate the potential chondroprotective effects of apigenin. Rabbit articular chondrocytes were cultured in a monolayer, and reverse transcription - polymerase...

We investigated whether prunetin affects the proteolytic activity, secretion, and gene expression of matrix metalloproteinase-3 (MMP-3) in primary cultured rabbit articular chondrocytes, as well as in vivo production of MMP-3 in the rat knee joint to evaluate the potential chondroprotective eff ect of prunetin. Rabbit articular chondrocytes were cultured in a monolayer, and reverse transcriptio...

Cordycepin is widely used as for its various pharmacological activities, such as anti-inflammation, anti-angiogenesis, anti-aging, anti-tumor and anti-proliferation. However, the precise role of cordycepin on chondrocytes is not clear. In the present study, we examined the inhibitory effects of cordycepin on interleukin-1 beta (IL-1β)-induced glycosaminoglycan (GAG) release, nitric oxide produc...

MicroRNAs (miRNAs) have important roles in the initiation and progression of human cancer, including breast cancer. We evaluated miR‑365 expression in breast cancer tissues, and investigated its effects on cell growth, cell cycle, cell invasion, and expression of its target gene ADAMTS-1. miR‑365 expression levels were analyzed in breast cancer tissues and adjacent normal tissues using qRT-PCR....

New onset thrombocytopenia and multiple organ failure (TAMOF) presages poor outcome in critical illness. Patients who resolve thrombocytopenia by day 14 are more likely to survive than those who do not. Patients with TAMOF have a spectrum of microangiopathic disorders that includes thrombotic thrombocytopenic purpura (TTP), disseminated intravascular coagulation (DIC) and secondary thrombotic m...

Von Willebrand factor (VWF) is a multimeric plasma glycoprotein present in endothelial cells, megakaryocytes, platelets, and connective tissue. It mediates platelet adhesion small arteries. VWF also binds protects coagulation VIII from degradation. Moreover, involved inflammatory response, linking hemostasis inflammation. multimers platelets attached to damaged or activated endothelium mediate ...

BACKGROUND Thrombotic thrombocytopenic Purpura (TTP) defined as ADAMTS-13 (A Disintegrin And Metalloprotease with ThromboSpondin type 1 domain 13) activity <10 % is a rare aetiology of thrombocytopenia during pregnancy, although the precise incidence is unknown. During pregnancy, the diagnosis of TTP is crucial as it has high feto-maternal morbidity-mortality and requires urgent plasma exchange...
