Objective: To investigate the expression and prognostic significance of insulin-like growth factor binding protein 5 (IGFBP5) in gastric adenocarcinoma (GAC). Methods:IGFBP5 expression in tissue samples from 236 GAC patients was analyzed us-ing immunohistochemical methods. These patients had undergone surgical resection between 20003 and 2006 in Sun Yat-Sen Universi-ty Cancer Center. The relationship between IGFBP5 expression and clinicopathological factors in the 236 GAC patients was analyzed using Pearson correlation analysis. The significance of IGFBP5 in predicting the survival status of these patients was analyzed using Ka-plan-Meier survival analysis and Cox's proportional hazards regression model. Results:Immunohistochemical staining data indicated that IGFBP5 expression was significantly decreased in 159 of the total GAC cases (67.4%). Of the 62 cases with well-and moderately differentiated GAC, 31 (50%) exhibited reduced IGFBP5 expression. Of the 174 cases with poorly differentiated GAC, 128 showed re-duced IGFBP5 expression. Reduced IGFBP5 expression was also observed in female patients and in patients with tumors over 5 cm in size or with poorly differentiated tumors (P<0.05). The reduced expression of IGFBP5 was common in the tumors that were staged as T3+4a/b andⅢ/Ⅳ(P<0.05). Kaplan-Meier survival analysis revealed that the reduced expression of IGFBP5 was associated with poor prognosis in GAC patients (P<0.001). Cox regression analysis identified IGFBP5 expression as an independent prognostic factor for the overall survival of these cancer patients (HR=1.897, P=0.029). Conclusion: IGFBP5 expression is reduced in GAC tissues, and IGFBP5 independently predicts an unfavorable prognosis in GAC patients.

Objective To investigate the effects of laminar shear stress ( LSS) on the proliferation and apoptosis of mesenchymal stem cells ( MSCs) . Methods The influences of laminar shear stress ( the physiological levels) on MSCs were studied. DNA synthesis and cell cycle were measured,to detect the cellular proliferation. The apoptosis-related gene expression ( Bcl-2/Bax) was examined to determine the effect of LSS. Results The percentage of MSCs’ proliferation rate was reduced by the fluid shear stress. Furthermore,it was detected that LSS exerted a potent suppression effect on MSC apoptosis. Conclusion These data revealed a critical role of LSS in maintaining the quies-cence of MSCs.

To examine the effects of ischemia and anoxia on cell activation and cell cycle of astrocytes in vitro, the cell cycles and the proliferation of astrocytes in different time points after ischemia and anoxia were studied by flow cytometry and BrdU labeling and the expression of GFAP and cyclin D1 was detected by the fluorescence immunochemistry. After ischemia and anoxia in vitro, the astrocytes in S phase were significantly increased as compared with those in the normal group and the proliferating ability of the astrocytes was highest 6 h after the treatment as revealed by BrdU pulse labeling, but the astrocytes in S phase and proliferating ability were decreased after 6 h. At the early stages of ischemia and anoxia, the positive staining intensity of GFAP was increased, peaked at 6th h, while 12 h after the ischemia and anoxia, the positive staining intensity of GFAP became weak, and the expression of cyclin D1 was gradually increased after the ischemic and anoxic damage. It is concluded that astrocytes are activated to proliferate and enter new cycle events by ischemia and anoxia, and cyclin D1 is implicated in the proliferation and repair of astrocytes. The cell cycle events are closely associated with the proliferation and activation of astrocytes.
