The present study is to elucidate the mechanisms underlying Gleevec-induced apoptosis of chronic myeloid leukemia (CML) K562 cells in vitro. The apoptotic cell death and cell cycle distribution after Gleevec treatment and the effect of PDCD4 siRNA on Gleevec-induced apoptosis of K562 cells were analyzed by flow cytometry. The effect of Gleevec on p-Crkl, caspase-3, PARP and PDCD4 protein levels, and the knockdown efficacy of PDCD4 siRNA were detected by Western blotting. The results showed that Gleevec dramatically suppressed the phosphorylation level of Crkl in a dose-dependent manner and induced significant apoptosis and G0/G1 cell cycle arrest of K562 cells in time- and dose-dependent manners. In addition, Gleevec activated caspase-3 and its downstream substrates PARP, and the caspase pan inhibitor Z-VAD-FMK (50 micromol x L(-1)) markedly reduced Gleevec-induced apoptosis from 47.97% +/- 10.56% to 31.05% +/- 9.206% (P < 0.05). Moreover, Gleevec significantly increased the protein expression of programmed cell death 4 (PDCD4). PDCD4 knockdown by siRNA reduced Gleevec-induced apoptosis from 46.97% +/- 14.32% to 42.8% +/- 11.43%. In summary, Gleevec induced apoptosis in K562 cells via caspase-3 activation.

Background Studies demonstrated that human amniotic epithelial cells (AECs) have some characteristics of embryonic stem cells and they were used to re-establish the surface of eyes. Human AECs may serve as new seed cells in tissue engineering for corneal epithelium reconstitution in the future. Objective The present study was to investigate the application value of human amniotic epithelium cells transfected by lentiviral vectormediated enhanced green fluorescent protein (EGFP) gene as new seed cell source for engineering the corneal surfacelayer. Methods Lentiviral vector carrying the objective gene EGFP was transfected into human amniotic epithelial cells (pLenti6/V5-DEST),and the transient expression of the transgene in the human amniotic epithelial cells was observed under the fluorescence microscope. Flow cytometry was used to detect the positive expression rates of EGFP in transfected cells. The transfected human amniotic epithelial cells were seeded onto the fresh corneal stromal surface of New Zealand white rabbit and cultured in vitro. The stem cell deficiency ( SCD ) models were established by cutting off the limbus of cornea in 20 eyes of New Zealand white rabbits, and the model rabbits were then divided into 2 groups randomly. The transplanted grafts carrying the pLenti6/V5-DEST-EGFP gene-transferred human amniotic epithelium cells were regarded as the pLenti6/V5-DEST-EGFP group, and the corneal stroma graft without any epithelial cell served as the control group. The opacity of stroma and corneal conjunctivalization and vascularization were observed daily. The rabbits' eyes were extracted one month after operation. The expression of EGFP in the cornea was detected under the fluorescence microscope, and the expression of CK8, CK18 and CK12 in cornea was detected by immunohistochemical staining. Results The shape of the transferred human amniotic epithelial cells resembled normal human amniotic epithelial cells. 48 hours after the transient transfection of EGFP presented with the highest expression level throughout the observation duration, with a positive expression rate of EGFP of 61.5% ,showing significant differences in comparison with that of 12 ( 5.24% ) , 24 ( 38.27% ) or 96 ( 39. 10% ) hours ( P ＜0. 05) post-transfection; but no obvious difference was found in the positive rate of transiently transfected EGFP between 48 hours and 72 hours ( 58.36% ) ( P＞0. 05 ). Six cornea grafts were clear in 1 month and two corneas were rejected during the observation period in the pLenti6/V5-DEST-EGFP group. A few new blood vessels were seen around the graft. Ten corneas of the control group became opaque and cloudy with new blood vessels growth around the grafts. Imunohistochemistry revealed the positive expressions of CK8, CK1 8 and CK12 in the corneal epithelial layer in the pLenti6/V5-DEST-EGFP group. However,the expression of CK12 was absent in the control group. Conclusion Human amniotic epithelium cells transfected with the pLenti6/V5-DEST-EGFP gene is a new and ideal feed cell type to reconstruct the corneal surface layer. Lentivirus is a relatively safe gene transfection vector.

AIMTo investigate the effects of resveratrol (Res) on the proliferation of VSMCs induced by Ang I and the expression of calmodulin (CaM) and calcineurin (CaN) in the proliferation of VSMCs treated by Ang 1 and to discuss the mechanism.

METHODSRabbit arterial VSMCs were cultured in vitro and VSMCs were identified with the method of immunocytochemistry. A cell proliferating model of VSMCs induced by AngII was established. VSMCs were cultured for 4-8 passages. The experiments were randomly divided into control group, AngII group (0.1 micromol/L) and AngII + Res groups with different concentrations(20, 40, 80, 160) micromol/L. VSMCs proliferation was determined with MTT colorimetric method. CaM was detected with Coomassie brilliant blue method and CaN was determined by enzyme reaction phosphorus measurement.

RESULTSRabbit VSMCs were cultured successfully and could be passaged. After immunocytochemistry staining, all the cells cytoplasm were stained and positive. Cell proliferation, CaM and CaN activities were increased significantly in VSMCs proliferation induced by AngII (P <0.05, P < 0.01). The index of AngII + Res groups were obviously reduced compared with AngII group ( P < 0.01).

CONCLUSIONThe VSMCs proliferation induced by AngII can be inhibited by Res significantly, and the inhibiting mechanism of Res may be related to inhibiting CaM and CaN activities then restraining the proliferation of VSMCs in a dose dependent manner.
