Notch signaling functions in the development of some types of leukemia and lymphoma, but the relationship between Notch signaling and chronic myeloid leukemia (CML) remains to be elucidated. In this study, we examined the expression of Notch receptors and ligands in the human CML cell line K562. When the active form of Notch1, the Notch intra-cellular(More)
Evidence has shown that Notch signaling modulates CD4+CD25+ regulatory T-cells (Tregs). As transcription factor Foxp3 acts as a master molecule governing the development and function of Tregs, we investigated whether Notch signaling might directly regulate Foxp3 expression. Here, we provide evidence that Notch signaling can modulate the FOXP3 promoter(More)
Since Notch signaling plays a critical role in stem cells and oncogenesis, we hypothesized that Notch signaling might play roles in cancer stem cells and cancer cells with a stem cell phenotype. In this study, we accessed potential functions of the Notch pathway in the formation of cancer stem cells using human glioma. Using RT-PCR, we found that most human(More)
In adults, angiogenic abnormalities are involved in not only tumor growth but several human inherited diseases as well. It is unclear, however, concerning how the normal vascular structure is maintained and how angiogenesis is initiated in normal adults. Using the Cre-LoxP-mediated conditional gene deletion, we show in the present study that in adult mice(More)
UNLABELLED Liver sinusoid (LS) endothelial cells (LSECs) support hepatocytes in resting livers and proliferate during liver regeneration to revascularize regenerated liver parenchyma. We report that recombination signal-binding protein-Jkappa (RBP-J), the critical transcription factor mediating Notch signaling, regulates both resting and regenerating LSECs.(More)
In order to investigate the patterns of FIX gene mutation in 3 unrelated hemophilia B (HB) patients, the activated partial thromboplastin time (APTT) and FIX activity (FIX: C) tests were adopted for phenotype diagnosis. All of the eight exons and their flank of FIX gene were amplified by polymerase chain reaction (PCR), the nucleic acid sequences were(More)
The study was aimed to investigate the factor V coagulation activity (FV:C), and to evaluate FVgene polymorphisms and activated protein C resistance (APCR) in the patients with venous thromboembolism (VTE). 95 patients with VTE and 95 normal controls were investigated for FV gene polymorphisms. FV Leiden, FVCambridge, and FVHong Kong were detected by PCR,(More)
This study was aimed to investigate the distribution of 1059 G/C gene polymorphism of C-reactive protein(CRP) in deep vein thrombus (DVT) and its clinical significance. Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) was used to screen 1059 G/C polymorphism in exon 2 of C-reactive protein gene in 61 cases of DVT and 60 healthy(More)
Objective of this study was to identify gene mutation involved in a patient with type 2A von Willebrand disease (vWD). The bleeding time, vWF:Ag, FVIII:C, RIPA and multimeric assay were used for phenotypic diagnosis. All of the 52 exons and the exon-intron boundaries of vWF gene were amplified by polymerase chain reaction (PCR) and direct sequencing was(More)
This study was purposed to investigate the correlation of deep vein thrombosis (DVT) with C-reactive protein (CRP), fibrinogen (Fg), coagulation factor VIII (FVIII:C), coagulation factor IX (FIX:C) and to explore the effect of inflammation and coagulation as well as their interaction in DVT and its mechanism. 59 patients with DVT undergoing selective venous(More)
