The conventional treatment options for advanced gastric carcinoma patients remain unsatisfactory in terms of response rate and overall survival benefit. Targeted therapy plus systemic chemotherapy now becomes a new promising therapeutic option. In this review we profiled important trials of international multicenter phase Ⅲ clinical studies in patients with advanced gastric carcinoma, including ToCA trial, EXPAND trial, LOGIC trial, AVAGAST trial, REAL3 trial, and granite-1 trial. These trials warrant the role of molecular targeted therapy in patients with advanced gastric carcinoma.

BACKGROUND:Studies have shown that cancer stem cels play an important role in tumor invasion and metastasis, but studies on the role of gastric cancer stem cels in invasion and metastasis of gastric cancer cels were rarely reported.
OBJECTIVE:To study the effect of gastric cancer stem cels CSC-G on invasion and metastasis of gastric cancer cels.
METHODS: Gastric cancer stem cels CSC-G and gastric cancer cels SGC7901 were culturedin vitro for 10 days folowed by spherical colony formation assay, western blot assay for detecting OCT4, SOX2, E-cadherin and CD44 protein expression levels in gastric cancer stem cels CSC-G and gastric cancer cels SGC7901, and Transwel assay for detecting the invasion and migration of gastric cancer stem cels and gastric cancer cels SGC7901.
RESULTS AND CONCLUSION:Gastric cancer cels SGC7901 in RPMI1640 medium presented with adherent growth and were quadrilateral or polygonal after passage; gastric cancer stem cels CSC-G in serum-free medium presented with suspension growth, and adherent gastric cancer stem cels were spindle-shaped or round. Compared with gastric cancer cels SGC7901, the protein expressions of OCT4, SOX2 and CD44, the number of cancer cel spheres and the number of trans-membrane cels were significantly increased in the gastric cancer stem cels CSC-G (P < 0.05), and the expression of E-cadherin protein was significantly decreased (P < 0.05). These findings indicate that the gastric cancer stem cels CSC-G can be successfuly cultured in vitro, and have enhanced invasion and migration compared with the gastric cancer cels SGC7901, which play an important role in gastric cancer invasion and metastasis.

Background and purpose: Previous studies have confirmed that the expression of leucine-rich repeat-containing 3B (CLRRC3B) was significantly decreased in different human cancers, which was also associated with the migration and invasion of cancer cells. The aim of this study was to explore the potential mechanism of LRRC3B in the development of esophageal cancer. Methods: The LRRC3B expression was detected in 60 cancer tissues and 60 adjacent non-neoplastic tissues by immunohistochemistry. The mRNA and protein expression of LRRC3B in Eca109 and HEECs were detected using real-time fluorescence quantitative polymerase chain reaction (RTFQ-PCR) and Western blot, respectively. Eca109 cells with different treatments were divided into three groups:normal group, negative control group (transfected with pCMV6 plasmid), overexpression LRRC3B group (transfected with pCMV6-LRRC3B plasmid). Transwell assay was used to measure the migration and invasion of Eca109 cells in different groups. The protein levels of E-cadherin, N-cadherin, Vimentin and p-Akt were determined by Western blot. Results: The expression of LRRC3B in esophageal cancer tissues was lower than that of non-cancerous tissues, as well as the expression of LRRC3B in Eca109 was decreased compared with that of normal esophageal epithelial cell line HEEC. Overexpression of LRRC3B significantly inhibited Eca109 cells migration and invasion, upregulated the expression of E-cadherin and decreased the expression of N-cadherin and Vimentin. Moreover, overexpression of LRRC3B significantly inhibited the phosphorylation of Akt in Eca109 cells. Conclusion: The expression of LRRC3B was decreased in esophageal cancer. Overexpression of LRRC3B can efficiently inhibit the EMT progression in esophageal cancer cells by suppressing PI3K/Akt signaling pathway.

Aim To assay the possible targets of adriamycin (ADM), screening ADM resistance related proteins.Methods The drug sensitivity of the cells was analyzed by IC50 assay;RT-PCR assay was used to detect the expression of genes in the cells;CMPK1 protein expression was tested by Western blot assay;the expression of CMPK1 in the cells was decreased by siRNA of CMPK1.Results Data from IC50 assay showed the sensitivity of cells transfected with CMPK1 was increased most(IC50 HEK293-CMPK /IC50 HEK293-Control=0.15, P<0.01), and the expression of CMPK1 protein in ADM resistant breast cells (MCF7/ADM) was lower than that in parent MCF7 cells (P<0.05).When the expression level of CMPK1 was decreased by CMPK1 siRNA, the sensitivity of MCF7 cells to ADM decreased (IC50 MCF7-siCMPK1/IC50MCF7-Control=3.6, P< 0.01), and the sensitivity of MCF7 cells to paclitaxel and gemcitabine also decreased.Conclusions CMPK1 was related to the multidrug resistance of cells, and the expression of CMPK1 was positively related to the sensitivity to drugs, which provides the possibility of CMPK1 as a target in the treatment of multidrug resistance.
