The aim of this study was to find out whether stimulated monocytes could trigger apoptosis of vascular endothelial cells. Human umbilical vein endothelial cells (HUVEC) (EC) were co-cultured for 24 h and 48 h with monocytes isolated from peripheral blood (peripheral blood monocytes) or MonoMac6 cell line activated previously with proinflammatory cytokines. Real-time PCR was conducted to investi...

OBJECTIVE High levels of circulating low-density lipoproteins (LDL) are a major atherosclerotic risk factor. The effects of intimal LDL on vascular smooth muscle cell (VSMC) phenotype and function during plaque remodeling and vascular repair are not fully understood. We have investigated whether exposure of VSMC to LDL induces changes on the proteomic profile of the heat shock protein (HSP) fam...

BACKGROUND Classical mammalian mitogen-activated protein kinase (MAPK) pathways consist of a cascade of three successive phosphorylation events resulting in the phosphorylation of a variety of substrates, including another class of protein kinases referred to as MAPK-activating protein kinases (MAPKAPKs). The MAPKAPKs MK2, MK3 and MK5 are closely related, but MK2 and MK3 are the major downstrea...

Heat shock protein 27 (HSP27) is a member of the heat shock protein family which has been linked to tumour progression and, most interestingly, to chemotherapy resistance in cancer patients. The present study examined the potential interplay between HSP27 and YangZheng XiaoJi, a traditional Chinese medicine used in cancer treatment. A range of cell lines from different tumour types including pa...

PURPOSE Heat shock protein 27 (HSP27) is known as the material that plays a role in apoptosis control in tumor and cell protection including the immune response, drug tolerance, and so on. In this study, HSP27 expression according to the prostate cancer malignancy level was evaluated, and HSP27 expression was also analyzed after inducing apoptosis by doxazosin treatment of the prostate cancer c...

The M(r) 27,000 heat shock protein (hsp27) is a member of the small heat shock protein family. Cell differentiation is a process in which a role for small heat shock proteins has been suggested. The ability to control the state of differentiation in normal human keratinocytes by modification of extracellular calcium concentration makes it an ideal in vitro system for exploration of the specific...

Selective inhibitors of factor Xa (FXa) are widely recognized as useful therapeutic tools for stroke prevention in non-valvular atrial fibrillation or venous thrombosis. Thrombin, which is rapidly generated from pro-thrombin through the activation of factor X to FXa, acts as a potent activator of human platelets. Thus, the reduction of thrombin generation by FXa inhibitor eventually causes a su...

Heat stress alters epithelial barrier function, and heat stress preconditioning protects epithelial function from injury. Hsp27 is a small stress protein that has previously been shown to modulate actin assembly. Thus, by regulating actin filaments associated with cell junctions, hsp27 could alter epithelial function. To begin to address this hypothesis, the regulation and distribution of a hum...
