BACKGROUND Protein C (PC) is one of the most important physiological inhibitors of coagulation proteases. Hereditary PC deficiency causes a predisposition to venous thrombosis (VT). The genetic characteristics of PC deficiency in the Chinese population remain unknown. METHODS Thirty-four unrelated probands diagnosed with hereditary PC deficiency were(More)
Chemotherapy for brain glioma has been of limited benefit due to the inability of drugs to penetrate the blood-brain barrier (BBB) and non-selective drug accumulation in the entire brain. To obviate these limitations, dual-targeting paclitaxel-loaded nanoparticles were developed by decoration with peptide-22 (PNP-PTX), a peptide with special affinity for(More)
As neovascular and glioma cells were closely associated and might be mutually promoted in glioma growth, a dual-targeting strategy targeting to both neovascular and glioma cells would be more promising as compared with those targeting one of them. In this study, we reported a drug delivery system where nanoparticles were decorated with EGFP-EGF1 (ENP), a(More)
In a strategy for anti-thrombotic therapy, we have expressed EGFP-EGF1 fusion protein, in which EGF1 can bind with tissue factor (TF). EGFP has previously been widely used as a fluorescent protein marker. EGFP-EGF1 protein was thiolated and conjugated to the malemide covering on the pegylated nanoparticles (NP) to form the EGFP-EGF1-NP. The EGFP-EGF1-NP was(More)
PECAM-1 is a 130-kDa member of the immunoglobulin (Ig) superfamily that is expressed on the surface of platelets and leukocytes, and at the intracellular junctions of confluent endothelial cell monolayers. Previous studies have shown that PECAM-1/PECAM-1 homophilic interactions play a key role in leukocyte transendothelial migration, in allowing PECAM-1 to(More)
Injured endothelium is an important target for drug and/or gene therapy because brain microvascular endothelial cells (BMECs) play critical roles in various pathophysiological conditions. RNA-mediated gene silencing presents a new therapeutic approach for treating such diseases, but major challenge is to ensure minimal toxicity and target delivery of siRNA(More)
The abundant extracellular matrix (ECM) in the glioma microenvironment play a critical role in the maintenance of glioma morphology, glioma cells differentiation and proliferation, but little has been done to understand the feasibility of ECM as the therapeutic target for glioma therapy. In this study, a drug delivery system targeting fibronectins (FNs), a(More)
Tissue factor (TF) is a 47 kDa membrane-bound glycoprotein, which is present at high concentrations on damaged endothelium, atherosclerotic plaques or tumor vasculature, and is an important trigger of coagulation cascade. In this study, we have expressed and purified the TF targeting protein-EGFP-EGF1, which was thiolated and conjugated to the malemide of(More)
No single biologic marker is used in the routine diagnosis of acute cerebral infarction. We screened for potential biomarkers in 92 plasma samples, including samples from 32 patients with acute cerebral infarction and 60 hospital control subjects. Pretreated plasma samples were analyzed using SELDI-TOF-MS (Ciphergen Biosystems, Fremont, CA). Proteomic(More)
The binding function of EGF1 domain peptide with tissue factor (TF) and its ability of triggering coagulation were explored. The TF expression model in vitro was established by lipopolysaccharide induction. The affinity of EGFP-EGF1 and TF expressing cells was analyzed by fluorescence microscopy and flow cytometry (FCM). The affinity of EGFP-EGF1 and rat(More)
