Radiotherapy is the main locoregional control modality for a number of types of malignant tumors, including glioblastoma. However, radiotherapy fails to prevent recurrence in numerous patients due to the intrinsic radioresistance of cancer cells. Cell senescence is significant in tumor suppressor mechanisms and is closely associated with the radioresistance(More)
RBP2 has been found to actively participate in cancer progression. It inhibits the senescence of cancer cells, mediates cancer cell proliferation and promotes cancer metastasis. It is also essential to drug tolerance. However, the effects of RBP2 on epithelial-mesenchymal transition are still unknown. In this study, we analyzed the effects of RBP2 on(More)
BACKGROUND A common genetic variant, telomerase reverse transcriptase (TERT) rs2736098, was recently reported to be associated with lung cancer risk in Caucasians. In addition, many studies have investigated the role of this polymorphism in the etiology of cancer of various organs. Nevertheless, the results of related case-control studies remain(More)
BACKGROUND Gold nanoparticles (GNPs) have been conceived to cause increased cytotoxicity of radiotherapy in human malignant cells. Greater uptake of GNPs by cells may induce increased radiation effects. Here we report the radiosensitization effect of glucose-capped GNPs (Glu-GNPs) with different sizes (16 nm and 49 nm) on MDA-MB-231 cells in the presence of(More)
Bevacizumab is an anti-VEGF human monoclonal antibody suitable for chemotherapy for patients with metastatic colorectal cancer (mCRC). This study investigated the efficacy and safety of using bevacizumab plus irinotecan, 5-fluorouracil, and leucovorin (FOLFIRI) as second-line chemotherapy option for patients with mCRC in China. Patients with mCRC, who had(More)
BACKGROUND Aberrant activation of phosphatidylinositol 3-kinase (PI3K)/Akt/mammalian target of rapamycin (mTOR) pathway may account for development of radioadaptation and is not rare in prostate cancer. Neither PI3K nor mTOR blockade could completely inhibit the pathway owing to paradoxical feedback, so we anticipate dual PI3K/mTOR blockade by NVP-BEZ235 to(More)
BACKGROUND CHRNA5-A3-B4, the gene cluster encoding nicotinic acetylcholine receptor subunits, is associated with lung cancer risk and smoking behaviors in people of European descent. Because cigarette smoking is also a major risk factor for esophageal squamous cell carcinoma (ESCC), we investigated the associations between variants in CHRNA5-A3-B4 and ESCC(More)
The three-dimensional conformal radiotherapy (3D CRT) plays an important role in the combination treatment of esophageal carcinoma. However, an accurate estimation of the clinical target volume (CTV) of esophageal squamous carcinoma (ESCC) by 3D CRT is still problematic. This study aimed to provide reference values for CTV estimation. The serial section(More)
An association between common variants in the 15q25 nicotinic acetylcholine receptor (nAChR) gene cluster CHRNA5-A3-B4 (responsible for encoding nAChR subunits) and lung cancer risk has recently been reported in both Caucasian and Chinese population. Cigarette smoking is one of the major risk factors for both lung and gastric cancer. Moreover, nAChR plays(More)
To improve the ability of superoxide dismutase (SOD) to suppress reactive oxygen species (ROS)-mediated injury, chemically modified derivatives of SOD with N,N,N-trimethyl chitosan chloride (TMC) and heparin, cationized SOD (TMC-SOD), and anionized SOD (heparin-SOD) were designed and prepared. In this study, the inhibitory effect of TMC-SOD and heparin-SOD(More)
