    [Show abstract] [Hide abstract] ABSTRACT: Background Our aim was to investigate the influence of FTS on human cellular and humoral immunity using a randomized controlled clinical study in esophageal cancer patients. Methods Between October 2013 and December 2014, 276 patients with esophageal cancer in our department were enrolled in the study. The patients were randomized into two groups: FTS pathway group and conventional pathway group. The postoperative hospital stay, hospitalization expenditure, and postoperative complications were recorded. The markers of inflammatory and immune function were measured before operation as well as on the 1st, 3rd, and 7th postoperative days (POD), including serum level of interleukin-6 (IL-6), C-reactive protein (CRP), serum globulin, immunoglobulin G (IgG), immunoglobulin M (IgM), immunoglobulin A (IgA) and lymphocyte subpopulations (CD3 lymphocytes, CD4 lymphocytes, CD8 lymphocytes and the CD4/CD8 ratio) in the patients between the two groups. Results In all, 260 patients completed the study: 128 in the FTS group and 132 in the conventional group. We found implementation of FTS pathway decreases postoperative length of stay and hospital charges (P < 0.05). In addition, inflammatory reactions, based on IL-6 and CRP levels, were less intense following FTS pathway compared to conventional pathway on POD1 and POD3 (P < 0.05). On POD1 and POD3, the levels of IgG, IgA, CD3 lymphocytes, CD4 lymphocytes and the CD4/CD8 ratio in FTS group were significantly higher than those in control group (All P < 0.05). However, there were no differences in the level of IgM and CD8 lymphocytes between the two groups. Conclusions FTS improves postoperative clinical recovery and effectively inhibited release of inflammatory factors via the immune system after esophagectomy for esophageal cancer. Trial registration ChiCTR-TRC-13003562, the date of registration: August 29, 2013.

    [Show abstract] [Hide abstract] ABSTRACT: Ras-related nuclear protein (Ran) GTPase is upregulated in non-small cell lung cancer (NSCLC) cells and is required for NSCLC cell survival. However, the effect of Ran on NSCLC cell invasion and epithelial to mesenchymal transition (EMT) remains unclear. This study found that Ran expression was much higher in highly invasive NSCLC cells than in lowly invasive NSCLC cells. Ectopic expression of Ran enhanced invasion and induced EMT in NSCLC cells. Inhibition of the PI3K-AKT pathway by LY294002, but not the MEK-ERK pathway by PD98509, reversed the above effects in these cells induced by Ran overexpression. In conclusion, our findings demonstrate that Ran induces EMT and enhances invasion in NSCLC cells through the activation of PI3K-AKT signaling. Thus, Ran may be a potential target for NSCLC therapeutic intervention.

    [Show abstract] [Hide abstract] ABSTRACT: Tumor suppressor in lung cancer 1 (TSLC1), a novel tumor suppressor gene, has been reported to be frequently inactivated in a variety of human malignant tumors. The aim of this study was to detect TSLC1 expression in human colon cancer and to analyze its association with prognosis of patients with colon cancer. Using quantitative real-time PCR and Western blot analysis, we found significantly decreased expression of TSLC1 in primary colon tumor tissues (n = 30) compared with adjacent normal tissues. Immunohistochemistry analysis also found decreased TSLC1 expression in 41.3 % (33/80) colon tumor tissues. In clinicopathological analysis, loss of TSLC1 expression significantly correlated with female gender and lymph node metastasis of colon cancer patients (P < 0.05). In addition, decreased expression of TSLC1 in tumors was found to be closely associated with a poor prognosis (P = 0.037, log-rank test), and multivariate analysis showed that lower TSLC1 protein expression was an independent prognostic factor for colon cancer patients. Our study suggests that down-regulated expression of TSLC1 may play an important role in the progression of colon cancer and TSLC1 expression may serve as a useful marker for the prognostic evaluation of patients with colon cancer.
