Background and purpose:miR-124 is considered to be a tumor suppressor in multiple tumors, including lung cancer, prostate cancer, bladder cancer, and breast cancer. However, its function is unclear in gastric cancer. This study aimed to explore the expression of miR-124 in human gastric mucosal epithelium cells and different gastric cancer cells, as well as gastric cancer tissues and matched para-cancerous tissues. The correlations of miR-124 expression with gender, age, histological grade, T stage, TNM stage, lymph node metastasis and prognosis of gastric cancer patients were analyzed.Methods:A real-time lfuorescent quantitative polymerase chain reaction (RTFQ-PCR) was employed for detecting the expression of miR-124 in human gastric mucosal epithelium cells and gastric cancer cells. The expression of miR-124 in gastric cancer tissues and matched para-cancerous tissues was detected by in situ hybridization.Results:The RTFQ-PCR results indicated that the expression of miR-124 was down-regulated in MKN-74, MKN-28, MKN-45, MGC-803, SGC-7901 and AGS cells compared to GES-1 cells.In situ hybridization showed that miR-124 was strongly expressed in normal gastric mucosa. However, low expression, focal positive expression or lack of miR-124 expression were observed in gastric cancer tissues. Statistical analysis showed that miR-124 was close-ly correlated to histological stage, TNM stage and node metastasis of gastric cancer patients, but not the age, gender and tumor size. The OS and DFS of the patients with low expression of miR-124 were shorter than that of the patients with high expression of miR-124. Multivariate analysis suggested that miR-124 down-regulation was an independent prog-nostic factor for survival in patients with gastric cancer.Conclusion:miR-124 is down-regulated in gastric cancer cells and tissues. The expression of miR-124 is correlated to histological stage, TNM stage, node metastasis and prognosis.

Objective To explore the effect of neural cell adhesion molecule (NCAM) on adhesion,migration and morphology of mouse bone marrow-derived mesenchymal stem cells (BMSCs).Methods We isolated and cultured BMSCs from wild-type and NCAM gene knockout mice.The expression of NCAM was detected by Western blot and immunofluorescence.Wound healing and adhesion assays were used to detect cell migration and adhesion ability respectively.The morphological changes were observed and the expressings of protein β1 integrin,E-cadherin,β-catenin and N-cadherin were analysed by Western blot.Results The migration and adhesion of BMSCs were significantly reduced after NCAM gene knockout.Meanwhile,the expression of β1 integrin was lower than those in wild-type BMSCs (P<0.01).The morphology of NCAM gene knockout BMSCs changed from irregular to flattened,and expressed epithelial identification marker E-cadherin and β-catenin (P<0.05).However,the expression level of mesenchymal identification marker N-cadherin was decreased (P<0.01).Conclusions NCAM is involved in adhesion and migration of BMSCs via regulating the expression of β1 integrin.Furthermore,NCAMmay negatively regulate the mesenchymal-epithelial transitions of BMSCs.

Objective:To determine the law of dose variation in nasopharyngeal carcinoma patients treated with helical tomotherapy by observing the difference between the actual and planned doses of targets and at-risk organs in these patients. Methods:Ten naso-pharyngeal carcinoma patients were treated with helical tomotherapy. Each single dose distribution and the corresponding computed tomography (CT) images were transmitted to the commercial software MIMvista 6.50, which was used to perform deformable image registration on the CT images. The sum of the actual dose was then obtained by accumulating the single doses. The image-guided actu-al dose was denoted as Plan 2, and the initial plan was called Plan 1. The dose-volume histogram of the dose distribution of targets and at-risk organs in Plans 1 and 2 were compared. Results:The D98 and D95 doses of the planning gross target volume (PGTV) in Plan 2 were significantly lower than those in Plan 1. Compared with Plan 1, the Dmean and D50 doses of double parotids in Plan 2 were higher by 42.23%and 63.82%(P<0.001, P=0.001) on average, respectively, for the left parotid, as well as by 38.64%and 66.76%(P=0.002, 0.004), respectively, for the right parotid. The D2 dose of spinal cord in Plan 2 was significantly higher than that in Plan 1. The doses were higher by 16.49%on average (P=0.026). Conclusion:To achieve precise and individually adaptive radiotherapy, correcting the error between anatomy and placement during tomotherapy for nasopharyngeal carcinoma patients is necessary.
