The aim of this study was to evaluate the predictive value of the polymorphism Glutathione S-transferase P1 (GSTP1) Ile105Val on oxaliplatin/5-FU-based chemotherapy in advanced gastric cancer. Patients with advanced gastric cancer accepted oxaliplatin/5-FU-based chemotherapy as first-line chemotherapy were investigated. GSTP1 Ile105Val polymorphism was detected by TaqMan-MGB probe allelic discrimination method. Response to treatment was assessed by disease controlled rate. Time to progression, overall survival and toxicities were recorded. Final patient outcomes were as follows: the allele frequencies of GSTP1 were 105Ile/105Ile 52%, 105Ile/105Val 41% and 105Val/105Val 7%. For patients with 105Ile/105Ile and those with at least one 105Val allele, disease control rate was 39% and 71% (P=0.026), respectively;median time to progression was 4.0 and 7.0 months (P=0.002); median overall survival time was 7.0 and 9.5 months (P=0.002). Neurological toxicity was more frequently occurred in patients with two 105Ile alleles (P=0.005). In conclusion, patients with at least one 105Val allele have better prognosis and response to oxaliplatin/5-FUbased regimen as first-line treatment for patients with advanced gastric cancer.

Wang, Zhen,Yu, Hong-Sheng,Yao, Ru-Yong,Qiu, Wen-Sheng,Yue, Lu,Sui, Ai-Hua,Liu, Xiang-Ping,Liu, Shi-Hai Asian Pacific Journal of Cancer Prevention 2013 Asian Pacific journal of cancer prevention Vol.14 No.1
Background: More and more research indicate that the immediately early response gene 3 (IER3) is involved inmany biological provesses, such as apoptosis and immunoreaction, as well as viral infection, tumorigenesis and tumour progression. Methods: Here we describe the construction of an eukaryotic expression vector containing IER3 gene and its expression in A549 cells as assessed through fluorescence microscopyand Western-blotting. Results: Fluorescence detection displayed that GFP in cytoplasm was high during 48 and 72 hours post-transfection. In addition, Western blotting showed significant increase in IER3 gene expression in the transfected cells compared with controls. Conclusion: The recombinate plasmid expression vector was constructed successfully, which may provide a basis for further exploration of function of IER3 in lung cancer.

Vasculogenic mimicry (VM) refers to the unique ability of highly aggressive tumor cells to mimic the pattern of embryonic vasculogenesis, which was associated with invasion and metastasis. The grape seed proanthocyanidins (GSPs) had attracted much attention as a potential bioactive anti-carcinogenic agent. However, GSPs regulation of VM and its possible mechanisms in a triple-negative breast cancer cells (TNBCs) remain not clear. Therefore, we examined the effect of GSPs on VM information in HCC1937 cell model. In this study, we identified the VM structure via the three-dimensional (3D) matrix in vitro. Cell viability was measured using the CCK8 assay. The effects of GSPs on human triple-negative breast cancer cells (TNBCs) HCC1937 in terms of related proteins of VM information were determined using western blot analysis. In vitro, the tubular networks were found in highly invasive HCC1937 cells but not in the non-invasive MCF-7 cells when plated on matrigel. The number of vascular channels was significantly reduced when cells were exposed in GSPs ($100{\mu}g$/ml) and GSPs ($200{\mu}g/mL$) groups (all p<0.001). Furthermore, we found that treatment with GSPs promoted transition of the mesenchymal state to the epithelial state in HCC1937 cells as well as reducing the expression of Twist1 protein, a master EMT regulator.GSPs has the ability to inhibit VM information by the suppression of Twist1 protein that could be related to the reversal of epithelial-to-mesenchymal (EMT) process. It is firstly concluded that GSPs may be an p otential anti-VM botanical agent for human TNBCs.
