    • 摘要: 食管鳞状细胞癌(ESCC)是世界范围内最常见的恶性肿瘤之一,在中国发病率较高。尽管铂类或其他细胞毒性药物化疗的最新进展对ESCC患者的治疗效果产生了一定的改善,但由于对ESCC细胞复杂的分子机制了解有限,缺乏更有效的治疗方法,5年的总体存活率仍然很低。粘着斑激酶(Focal adhesion kinase,FAK)是由PTK2编码的胞浆非受体酪氨酸激酶,在多种肿瘤中表达失调,与临床预后不良相关,尤其是在ESCC。

    • 摘要: Objective: To investigate the effects of sodium valproate (VPA) on the expression of FAK and FAK-pY397 in hippo-campus of rats with seizure induced by pentylenetetrazole (PTZ). Methods: A total of 75 rats were randomly divided into 5 groups:the normal control group, the epilepsy model group (PTZ group) and the VPA groups(150,300 and 600 mg·kg-1·d-1)with 15 ones in each group. The model rats were continuously given PTZ (32 mg·kg-1·d-1) by intraperitoneal injection for 4 weeks and paid close attention to the behavioral changes, and then VPA was administrated orally for 2 weeks. The pathological changes of hippo-campus tissue were observed by HE staining. The expressions and distributions of FAK, FAK-pY397 and integrin in serum and hippo-campus were evaluated by immunohistochemical assay and enzyme-linked immunosorbent assay (ELISA). Results: Compared with the model group, the symptoms of epilepsy in VPA groups were significantly relieved and cell apoptosis was improved. Immunohistochemis-try showed that the expression of FAK-pY397 decreased significantly in VPA groups with the increase of sodium valproate dose, and there was no significant difference in the expression of ITGα3. The VPA groups significantly reduced the expression of FAK, FAK-pY397 and ITGβ1(P<0. 05), the expression of FAK and ITGβ1 protein in peripheral serum decreased significantly (P<0. 05), but the expression of FAK-pY397 did not change significantly. Conclusion: VPA can effectively participate in or affect the process of epi-lepsy by inhibiting the expressions of FAK-pY397 and ITGβ1 in hippocampal tissue of epileptic rats.%目的:探讨抗癫痫药丙戊酸钠(VPA)对戊四氮(PTZ)致痫模型大鼠海马组织中粘着斑激酶( FAK)、FAK-pY397表达水平的影响.方法:将75只大鼠随机分为正常对照组,模型组,VPA低、中、高剂量组(150,300,600 mg·kg-1·d-1)5组,每组15只.造模大鼠连续腹腔注射戊四氮32 mg·kg-1·d-14周,密切观察大鼠行为学变化.造模成功后,VPA各组给予相应剂量VPA灌胃,连续2周.苏木精-伊红( HE)染色观察大鼠海马组织变化;免疫组化及酶联免疫吸附法( ELISA)检测大鼠外周血清及海马组织中FAK、FAK-pY397及整合素表达情况.结果:与模型组比较,VPA各组癫痫症状有明显缓解,细胞凋亡情况有所改善;免疫组化发现VPA组FAK-pY397 的表达明显下降,且随着VPA剂量的加大,FAK-pY397 的表达有下降趋势, ITGα3表达组间无显著差异;VPA低、中、高剂量组海马组织中FAK,FAK-pY397及整合素ITGβ1表达水平下降,差异具有显著性(P<0. 05);外周血清中FAK及整合素ITGβ1 蛋白表达水平显著下降(P<0. 05),但FAK-pY397 表达无明显变化.结论: VPA可能通过抑制癫痫大鼠海马组织中FAK-pY397及ITGβ1的表达,参与或影响癫痫过程.

    • 摘要: Objective To investigate whether the effect of physiological micro-electrical field on migration/invasion of trophoblast cells in vitro was associated with integrins expression of the cells.Methods The trophoblast cells were exposed to the direct current electrical field (DC-EF) at 150 mV/mm for 5,10 and 15 hours.Cell images and migration distance were recorded with continuous photographing and analyzed by image analyzer.The activation of FAK at 5,10,30 and 60 min of DC-EF stimulation were measured and the expression levels of integrinα1,integrinα5,integrinαV and integrinα1 were detected by using Western blot assay.Results The application of 150 mV/mm DC electrical stimulation,trophoblast cells cultured in media containing 10% calf serum showed a cathode migration.The migration velocity and distance were obviously increased when compared to the control group without EF stimulation (P =0.021).The cells exposed to the EF also showed elongation and perpendicular orientation,while control cells that were not subjected to EF showed no such responsiveness.Compared with the non-EF stimulation controls,trophoblasts under EF stimulation had a quickly activation of FAKTyr397 location within 60 min (P < 0.05),while no significant changes in expressions of integrinα1,integrinα5,integrinαV and integrinα1 were observed (P > 0.05).Conclusion The physiological direct current electrical field may activate FAK by non-integrin pathway to promote trophoblast cell migration/invasion function.However,its detailed mechanism needs further studies.%目的 探讨生理性微电场促进体外培养的人胎盘滋养细胞迁移/侵袭功能是否与滋养细胞表面整合素(integrin)表达有关.方法 用150 mV/mm的直流微电场刺激滋养细胞,时间分别为5、10和15 h,测定其迁移情况并观察细胞形态变化.Western blot检测刺激前后1h内粘着斑激酶FAK活化情况和细胞表面integrinα1、integrinα5、integrinαy和integrinα1蛋白表达水平.结果 在含有10%胎牛血清的培养基中,150 mV/mm电场刺激下滋养细胞向负极定向迁移,迁移速度和距离较对照组明显增加(P=0.021),胞体拉长,垂直于电场方向排列;胞内FAKTyr397位点于刺激后5、10、30、60 min内迅速活化并逐渐加强(P<0.05);刺激前后滋养细胞表面integrinα1、integrinα5、integrinαV、和integrinα1蛋白表达水平无明显改变(P>0.05).结论 生理性直流微电场可能通过非整合素途径活化FAK从而促进滋养细胞迁移/侵袭功能,但其详细机制仍需进一步研究.

Methods:The PGPU6/GFP/shNC(shNC)and PGPU6/GFP/FAK-299(shRNA-299)were designed and transfected into SGC-7901 cells. Interference effect of FAK was detected by Real-time PCR and Western blots. MTT assay was used to examine changes in cell proliferation. Cell apoptosis was analyzed by flow cytometry. The ex-pression of associated apoptotic factors was measured by Western blots. Results:The expression of FAK in SGC -7901 cells significantly decreased in shRNA-299 group by contrast to the control group(P﹤0. 05). Cells prolifera-tion was inhibited by shRNA-299(P﹤0. 05)and the level of cell apoptosis in shRNA-299 group was higher than in the control group(P﹤0. 05). Western blots show an up-regulation of cleaved PARP,cleaved caspase-9,cleaved caspase-3,p53 and Bax,and a decrease in the expression of Bcl-2 protein in shRNA-299 group. Conclusion:FAK inhibition by shRNA-299 could activate apoptosis-associated proteins and induce apoptosis of human gastric carcinoma cells SGC-7901.
