Objective To explore the expression and clinical significance of Twist. E-cadherin and N-cadherin in gallbladder carcinoma. Methods From 2000 to 2008, in Zhejiang Provincial People's Hospital, the expression of Twist, E-cadherin and N-cadherin protein were detected in 79 surgically removed gallbladder carcinoma tissue specimens in paraffin blocks and 20 normal gallbladder tissue specimens by tissue microarray technique and immunohistochemistry. Results Compared with normal gallbladder tissues, the expression of Twist and N-cadherin was up-regulated in gallbladder carcinoma tissues and the positive percentage was 68.3% and 49.4% respectively, while which both were 1/20 in normal gallbladder tissues. The percentage of high E-cadherin expression in gallbladder carcinoma tissues was only 27.8 %, which was significantly lower than that in normal gallbladder tissues (20/20;X2 =29.31, P<0. 05). The expression of Twist was correlated with T classification, lymph node metastasis, distant organ metastasis, hepatoduodenal ligament invasion, lymphatic invasion and UICC stage of gallbladder carcinoma (P<0.05). The expression of E-cadherin was correlated with T classification, distant organ metastasis, hepatoduodenal ligament invasion, differentiation degree and UICC stage of gallbladder carcinoma (P<0.05). The expression of N-cadherin was only correlated with lymphatic invasion of gallbladder carcinoma (P <0.05 ). There was significant negative correlation between Twist and E-cadherin expression (P<0. 01). All the 79 gallbladder carcinoma patients were followed up after the surgery, the mean follow-up time was 30.6±14.3months. The 3-year survival rates of patients with low or high Twist expressions were 66% and 7% respectively,there was significant difference between the two groups(P<0. 01). The 3-year survival rates of patients with low or high E-cadherin expressions were 25 % and 86 % respectively, the difference of two groups was significant(P<0.01). The 3-year survival rates of patients with low or high Ncadherin expressions were 39% and 41% respectively, there was no significant difference between the two groups(P>0.05). The multivariate analysis indicated that the Twist expression was one of independent prognostic factors of gallbladder carcinoma. Conclusion The abnormal expression of Twist and E-cadherin was correlated with the development and progression of gallbladder carcinoma,and Twist expression was one of the independent prognostic factors of gallbladder carcinoma.

AIM:To screen the gene expression profiles of normal gastric mucosa,primary gastric cancer and metastatic lymph nodes by gene expression microarray and the associated genes with lymph node metastasis by bioinformatics. METHODS:The differentially expressed genes of nontumorous gastric mucosa (group A),primary gastric cancer (group B) and metastatic lymph nodes (group C) were screened by gene expression microarray obtained from Affymetrix company. The results were further analyzed by bioinformatic software including Gene Expression Profiles Analysis of Cohort Experiment,Gene Ontology Enrichment Analysis and Pathway Significant Analysis. The expression of TLN1 in group A,B and C were confirmed by real-time reverse transcription PCR. RESULTS:278 genes were persistent up-regulated in group A,B,C,which participated mainly in immunologic responses,cell adhesion,phosphate transport,inorganic anion transport,cell chemotaxis,cell motility and signal transduction. While 387 genes were persistent down-regulated in group A,B,C,which were concerned with digestion,glucide metabolism,lipid metabolism,protein metabolism,one-carbon compound metabolism,nitrogen compound catabolism and cell adhesion. The pathway analysis suggested that integrin-mediated cell adhesion pathway were abnormally regulated. These genes including THBS1,TLN,CAPN3,ITGAX,SORBS1,CAPN6,CAPN9 were continuous up-regulated or down-regulated in integrin-mediated cell adhesion pathway. The expressions of TLN1 in group A,B,C were 0.0000342?0.0000711,0.1064?0.1251 and 0.2886?0.3529,respectively. The expression of TLN1 in metastatic lymph nodes was significantly higher than that in nontumorous gastric mucosa and primary gastric cancer (P

The cells containing 5-hydroxytryptamine (5-HT) in the antrum of the SD rat's stomach were demonstrated by means of Sternberger's PAP immunohistochemical method and quantitative analysis were performed by means of Weibel's stereological method. The results were as follow: The 5-HT immunoreactive cells in the antrum of the rat's stomach were found only in the surface epithelium and the glandular epithelium of the mucosa. The volume density (V_v) was 0.0038?0.0004, the surface density (N_A) was 42.86+3.20 cells/mm~2 and the numerical density (N_v) was 2627.11?200.42 cells/mm~3. The distribution of 5-HT reactive cells showed an obvious regional difference. From the lesser curvature to the greater curvature of stomach, the cell density decreased gradually. The cell density was the highest in the lesser curvature: N_A was 59.96?3.48 cells/mm~2, Nv was 3729.23?216.89 cells/mm~3; and was second high in the two side walls: N_A was 42.39?3.48 cells/mm~2, Nv was 2647.18+216.57 cells/mm~3; and was lowest in the greater curvature: N_A was 29.39? 4.49 cells/mm~2, N_v was 1843.00?280.09 cells/mm~3. Most of the 5-HT immunoreaclive cells were found in the basal third section of the mucosa and the cell density was the highest. N_A was 92.33?6.92 cell/mm~2,N_v was 5336.28?410.22 cells/ mm~3; in the middle one third of the mucosa, the cell density came to next: N_A was 27.69?2.38 cells/mm~2, N_A was 1708.68?146.65 cells/mm~3; and in the superficial third section of the mucosa, the cell density was the lowest: N_A was 7.29?0.53 cells/mm~2, N_v was 457.00?35.44 cells/mm~3. In addition, a detailed observation on the morphology of the 5-HT immunoreactive cells was also undertaken.

Objective To investigate the anticancer activities of resveratrol on malignant melanoma cells in vitro and involved mechanisms. Methods A375 human malignant melanoma cells and B16-F1mouse malignant melanoma cells were cultured and treated with various concentrations of resveratrol for different durations. The cell proliferation, apoptosis and cycle of both B16-F1 and A375 cells were detected with MTT assay, Annexin V-F1TC/propidium iodide (PI) double staining flow cytometry and propidium iodide flow cytometry, respectively. Western blot analysis was performed to measure the expression of Bcl-2 and Bax protein in both cells. Results Resveratroi inhibited the proliferation of A375 and B16-F1 cells in a time- and dose- dependent manner. The apoptosis rate of A375 cells was (16.7±2.1 )%, (17.2±1.7)% and (52.3±4.1 )% after treatment with resveratrol of 25 μmol/L for 24 hours, resveratrol of 100 μmol/L for 12 and 72 hours, respectively;, and resveratrol of 100 μmol/L induced the apoptosis of B16-F1 at a rate of ( 18.4±1.6)%, (39.6±3.3 )% and (56.7±4.5 )% at 12, 24 and 72 hours, respectively. Flow cytometry showed that A375 and B16-F1 cells treated with resveratrol were arrested in the G1 phase of cell cycle, and the blocking effect increased in a dose-dependent manner. The percentage of A375 and B16-F1 cells in G1 phase was (40.51±3.97 )% and (41.34±3.12 )%, respectively, after 24-hour treatment with resveratrol of 25 μmol/L,(55.64±4.95)% and (53.93±5.12)%, respectively with resveratrol of 100μmol/L for the same duration.The expression of Bcl-2 protein was decreased in malignant melanoma cells treated with resveratrol,while that of Bax protein increased. Conclusions Resveratrol can effectively inhibit the proliferation of malignant melanoma cells by regulating the cell cycle and inducing cell apoptosis, which seems to be associated with the regulation of Bcl-2 and Bax expressions.
