BACKGROUND/AIMS Bone marrow (BM)-derived endothelial progenitor cells (EPCs) play a critical role in angiogenesis and vascular repair. Some environmental insults, like fine particulate matter (PM) exposure, significantly impair cardiovascular functions. However, the mechanisms for PM-induced adverse effects on cardiovascular system remain largely unknown.(More)
Polychlorinated biphenyls (PCBs) possessed much potential hazard to environment because of its chemical stability and biological toxicity. Here, we identified the binding mode of a representative compound, PCB153, to human serum albumin (HSA) using fluorescence and molecular dynamics simulation methods. The fluorescence study showed that the intrinsic(More)
AIMS The present study was to investigate the effect of hydrogen peroxide (H2O2) on bone marrow stem cells and their endothelial differentiation and the underlying mechanisms in vitro. MAIN METHODS Rat bone marrow multipotent adult progenitor cells (MAPCs) were used as the source of bone marrow stem cells, and treated with H2O2 (with the final(More)
Multipotent mesenchymal stem cells have recently emerged as an attractive cell type for the treatment of diabetes-associated wounds. The purpose of this study was to examine the potential biological function of human placenta-derived mesenchymal stem cells (PMSCs) in wound healing in diabetic Goto-Kakizaki (GK) rats. PMSCs were isolated from human placenta(More)
Esophageal quamous cell carcinoma (ESCC) is the predominant histological type of esophageal carcinoma in Asian populations. To date, few biomarkers have been identified for ESCC. In present study, we found a tumor suppressor, NUMB isoform 1 (NUMB-1), as a promising prognostic biomarker for patients with ESCC. NUMB-1 mRNA was downregulated in 66.7% of(More)
BACKGROUND Syndecan-1(Sdc1) plays important roles in many steps of inflammatory responses. In ulcerative colitis patients, decreased Sdc1 expression was observed and Sdc1 analogue heparin could improve the disease course. A better understanding of how Sdc1 functions in colitis will benefit the disease intervention. AIMS To evaluate the role of Sdc1 in(More)
Phthalate esters (PAEs) are globally pervasive contaminants that are considered to be endocrine disruptor chemicals and toxic environmental priority pollutants. In this paper, the interactions between PAEs and human serum albumin (HSA) were examined by molecular modelling, steady state and time-resolved fluorescence, ultraviolet-visible spectroscopy(More)
Colorectal cancer is one of the most common malignancies in the world. Overactivity of phosphatidylinositol 3-kinase (PI3K) is frequently detected in colorectal carcinoma. PI3K signaling plays a pivotal role in intracellular signal transduction pathways involved in cell growth, cellular transformation, and tumorigenesis. To specifically inhibit PI3K(More)
In the present study, the interaction of vanillin and human serum albumin (HSA) has been characterised by molecular modelling, fluorescence, Fourier transform infrared (FT-IR) and circular dichroism (CD) spectroscopic methods. The results of molecular modelling suggested that vanillin was located within the binding pocket of subdomain IIA of HSA mainly by(More)
BACKGROUND Peripheral artery disease (PAD) is a major health burden in the world. Stem cell-based therapy has emerged as an attractive treatment option in regenerative medicine. In this study, we sought to test the hypothesis that stem cell-based therapy can ameliorate ischemia induced limb injury. METHODS We isolated mesenchymal stem cells derived from(More)
