Radiotherapy is an essential component of the standard therapy for newly diagnosed glioblastoma. To increase the radiosensitivity of glioma cells is a feasible solution to improve the therapeutic effects. It has been suggested that inhibition of signal transducer and activator of transcription 3 (STAT3) can radiosensitize glioma cells, probably via the(More)
Secreted protein acidic and rich in cysteine (SPARC) has been shown to play an important role in the promotion of glioma. In this study, we investigated the effects of downregulated SPARC expression on the radiosensitivity of human glioma U-87MG cells and its possible mechanism. With a small-interfering RNA (siRNA) expression plasmid vector targeting SPARC,(More)
TP53-induced glycolysis and apoptosis regulator (TIGAR) knockdown is proven to radiosensitize glioma cells, but the mechanisms are not fully understood. Thioredoxin-1 (TRX1) is a redox-sensitive oxidoreductase, which plays critical roles in DNA damage signal transduction via nuclear translocation in irradiated cells. Because the TRX1-dependent DNA damage(More)
This study is designed to examine the radiosensitizing effects of coexpression of doublecortin (DCX) and secreted protein and rich in cysteine (SPARC). Previously, we showed that downregulation of SPARC by small interfering RNA increased radioresistance of U-87MG glioma cells. Therefore, overexpression of SPARC might increase radiosensitivity of glioma(More)
Our previous study proved that TP53-induced glycolysis and apoptosis regulator (TIGAR) abrogation is able to radiosensitize glioma cells. Whether TIGAR over-expression has radio-protective effect in human parotid gland cells is still unknown. In this study human parotid gland fibroblast Hs 917.T cells were transfected with pcDNA3.1-TIGAR, and clonogenic(More)
The up-regulation of thioredoxin reductase-1 (TrxR1) is detected in more than half of gliomas, which is significantly associated with increased malignancy grade and recurrence rate. The biological functions of NADPH-dependent TrxR1 are mainly associated with reduced thioredoxin-1 (Trx1) which plays critical roles in cellular redox signaling and tumour(More)
OBJECTIVES To assess the effectiveness and safety of Chinese herbal medicine (CHM) for the treatment of aspirin resistance (AR). METHODS A comprehensive research of seven electronic databases was performed for comparative studies evaluating CHM for AR. Two authors independently extracted data and assessed the methodological quality of the included trials(More)
High on-aspirin platelet reactivity (HAPR) has been associated with compromised aspirin efficacy in patients with diabetes suffering from acute cardiovascular events, but the key mechanisms remain elusive. The objective of this study was to uncover the potential link between pathogenic accumulation of salicylic acid (SA), the major metabolite of aspirin,(More)
Antigen binding to the B-cell receptor (BCR) induces several responses, resulting in B-cell activation, proliferation, and differentiation. However, it has been difficult to study these responses due to their dynamic, fast, and transient nature. Here, we attempted to solve this problem by developing a controllable trigger point for BCR and antigen(More)
FcγRIIB functions to suppress the activation of immune cells. A single-nucleotide polymorphism in the transmembrane (TM) domain of FcγRIIB, FcγRIIB-T232, is associated with lupus. In this study, we investigated the pathogenic mechanism of FcγRIIB-T232 at both functional and structural levels. Our results showed that FcγRIIB-T232 exhibited significantly(More)
