Objective To establish the expression profiles of microRNA (miRNA) in SMMC-7721 and CCC-HEL-1 cell lines in order to provide new clues to study the mechanism of miRNA function in hepatocellular carcinoma (HCC) and its treatment. Methods SMMC-7721 and CCC-HEL-1 cell lines were cultured in vitro. Total RNAs were extracted by TRIzol, followed by RNA quantification and quality control. The RNAs were used to detect the expression of miRNA in these two cell lines by miRNA array. The miRNA of interest was then verified by real-time PCR. Results In total,238 differentially expressed miRNAs were found, including 154 overexpressed and 84 underexpressed miRNAs. 64 miRNAs were upregulated more than 4 times and26 miRNAs were upregulated more than 10 times. 22 miRNAs were downregulated more than 4 times 10 miRNAs weredownregulated more than 5times, and 1 miRNA was downregulated more than 10 times. Real-time PCR validation suggested that has-miR-205 and has-let-7f in liver cancer increased by 2. 7 and 2. 3 times, respectively.Conclusion There are differences in the expression of miRNA between the SMMC-7721 and CCC-HEL-1 cell lines and the profiles of miRNA expression were established for both cell lines. It was found that has-miR-205 and has-let-7f were upregulated in liver cancer.

OBJECTIVETo screen and identify the serum specific protein markers of patients with gastric cancer by proteomics technology, and to provide more comprehensive serum protein fingerprint model for the early diagnosis of gastric cancer.
METHODSPreoperative and postoperative blood samples were collected from 60 gastric cancer patients. Mass spectrometry (SELDI-TOF-MS) technology was used to detect and screen serum specific proteins in gastric cancer patients(preoperative group, postoperative group, metastasis group), and the result was compared with normal control group. Gel electrophoresis(TRICINE SDS-OAGE) technology was applied in the separation and purification for those different protein. Matrix assisted laser desorption ionization tandem time-of-flight mass spectrometry (MALDI-TOF/TOF) technology was used in the identification for the proteins following separation and purification.
RESULTMass spectrometry data of preoperative group and normal group resulted in 15 specific m/z peak(P<0.01). SVM screened by a combination of the highest index model Youden get m/z peak at 6 449.1 protein markers. The protein expression of preoperative group was significantly higher than that of normal group(2 299.3±2 029.3 vs. 509.5±168.3, P<0.01). Mass spectrometry data of preoperative group and postoperative group resulted in 6 specific m/z peak(P<0.01). SVM screened by a combination of the highest Youden index model indentified get m/z peak at 6 449.2 protein markers. The protein expression of preoperative group was significantly higher than that of postoperative group(1 247.9±685.0 vs. 476.5±157.8, P<0.01). Mass spectrometry data of preoperative group and metastasis group resulted in 12 specific m/z peak (P<0.01). SVM screened by a combination of the highest Youden index model indentified get m/z peak at 6 448.9 protein markers. The protein expression of metastasis group was higher than that of preoperative group(1 506.9±1 036.5 vs. 649.7±621.0). MALDI-TOF/TOF identified that the protein with m/z peak at 6 449 was Apo CIII(.
CONCLUSIONApo CIII( may be the specific serum protein marker of gastric cancer, which may provide a more comprehensive serum protein fingerprint model for the early diagnosis of gastric cancer and a new way for further research.

Objective To investigate the effect of EP4 gene silencing on the growth and migration of K1 cells. Methods K1 cells with stable knockdown of EP4 were constructed with lentiviral vector. QRT-PCR and western blot analysis were used to detect the expression of EP4 mRNA and protein in K1 cells. CCK8 assay and flow cytometry were employed to measure cell viability and apoptosis. Transwell assay was applied to detect cell migration. Results Compared with the negative control group,the mRNA and protein expression of EP4 were sig-nificantly decreased in K1 cells with stable knockdown of EP4. Furthermore,shRNA-mediated silencing of EP4 gene remarkably suppressed cell viability and induced apoptosis of K1 cells.The migration of K1 cells with knock-down of EP4 was decreased compared with the negative control group. Conclusions EP4 gene silencing can in-hibit growth and induce apoptosis of K1 cells.Downregulation of EP4 can significantly reduce migration of K1 cells.
