BACKGROUND Single nucleotide polymorphisms (SNPs) in microRNA-coding genes may participate in the process of carcinogenesis by altering the expression of tumor-related microRNAs. It has been suggested that two common SNPs rs2910164 in miR-146a and rs11614913 in miR-196a2 are associated with susceptibility to hepatocellular carcinoma (HCC). However,(More)
Pharmacogenetic advances in cancer chemotherapy have the potential to predict clinical benefit to particular regimens. Platinum agents have shown to be effective in the treatment of gastric cancer. We assessed whether single nucleotide polymorphisms (SNPs) in xeroderma pigmentosum group D (XPD), X-ray repair cross complementing group 1 (XRCC1) and(More)
OBJECTIVE Chemoresistance is a major obstacle to successful cancer chemotherapy. In this study, we examined the ability of gambogic acid (GA) to reverse docetaxel resistance in BGC-823/Doc gastric cancer cells. METHODS The cytotoxic and apoptotic effect of drugs were evaluated by MTT assay and double staining with both Annexin-V-FITC and PI. Cell cycle(More)
To further evaluate the novel docetaxel-loaded micelle based on the biodegradable thermosensitive copolymer poly(N-isopropylacrylamide-co-acrylamide)-b-poly(dl-lactide) that we had synthesized before, in this paper, we studied its in vitro cytotoxicity in three different tumor cell lines by standard MTT assays using different tumor cell lines, followed by(More)
Cancer is the leading cause of death in the world. Development of minimally invasive biomarkers for early detection of cancer is urgently needed to reduce high morbidity and mortality associated with malignancy. MicroRNAs (miRNAs) are small regulatory RNAs that modulate the activity of specific mRNA targets and play important roles in a wide range of(More)
Targeted delivery of antitumor drugs triggered by hyperthermia has significant advantages in clinical applications, since it is easy to implement and side effects are reduced. To release drugs site-specifically upon local heating often requires the drugs to be loaded into a thermosensitive polymer matrix with a low critical solution temperature (LCST)(More)
OBJECTIVE To review the biological behaviour of endothelial progenitor cells and their role and significance in tumour vasculogenesis. DATA SOURCES The data in this review were mainly from Medline and PubMed for the relevant articles in English published from March, 1997, to March, 2008. The search terms were 'endothelial progenitor cells' (EPCs) and(More)
cis-Dichlorodiamminoplatinum (II) (cisplatin) has demonstrated extraordinary activities against a variety of solid tumors. However, the clinical efficacy is contrasted by its toxicity profile. To reduce the toxicity and enhance the circulation time of cisplatin, core-shell structure nanoparticles were prepared from block copolymer of methoxy poly(ethylene(More)
BACKGROUND Hepatocellular carcinoma (HCC) remains a disastrous disease and the treatment for HCC is rather limited. Separation and identification of active compounds from traditionally used herbs in HCC treatment may shed light on novel therapeutic drugs for HCC. METHODS Cell viability and colony forming assay were conducted to determine anti-HCC(More)
Breast cancer susceptibility gene 1 (BRCA1) has a central role in chemotherapy-induced DNA damage response. The protein inhibitor of activated STAT (PIAS) family of proteins, PIAS1 and PIAS4, are also necessary for adequate DNA damage repair. To further understand the role of BRCA1 in DNA repair, we examined the mRNA expression of these genes in 133(More)
