FasL基因表达对缺氧状态下直肠癌细胞增殖凋亡的影响

Objective To elucidate the effect of FasL gene expression on the proliferation and apoptosis of hypoxic rectal carcinoma cells. Methods The normoxic expression level of FasL in HR-8348 subtype cells (HR-8348B, HR-8348L, HR-8348F and HR-8348As) with different invasive power were verified by Western blot. Hypoxia models for HR-8348B, HR-8348L, HR-8348F and HR-8348As were constructed with chemical modeling, then the FasL levels in all groups at 12 h after hypoxia were quantitated by Western blot. Distribution of different cell life cycles was determined with flow cytometry. Cell reproductive activities were detected with MTT method, and cell apoptesis was assessed with TUNEL. Results FasL protein was pigmentized at the position of 40 000 by Western blot, and the expression level of FasL was significantly higher in HR-8348F cells than those in HR-8348B, HR-8348L and HR-8348As cells(F=361.149, P<0.01) in normoxia. At 12 h after hypoxia, the FasL level was also significantly higher in HR-8348F cells than those in other groups (F=278.766, P<0.01), but was not markedly different as compared to themselves in normoxia (t=1.762, P>0.05). The proliferation index was significantly higher in HR-8348F (60.43±3.72) than those in HR-8348B (40.01±3.30), HR-8348L (41.30±4.06) and HR-8348As cells (35.87±4.39), respectively (F=39.477, P<0.01). However, both inhibition rate of proliferation and apoptotic index were remarkably lower in HR-8348F (17.30±1.98 and 13.10±1.04) than those in HR-834B (33.70±4.33 and 21.60±1.31), HR-8348L (34.20±3.92 and 20.10±1.15), and HR-8348As (38.00±4.55 and 23.90±1.23), respectively (F=28.811 and 76.462, respectively, P<0.01). Conclusion The expression enhancement of intracellular FasL in rectal carcinoma in hypoxia can lead to accelerated proliferation and reduced apeptosis of cells, which will promote tumor cells to adapt microenvironmental hypoxia.     

大肠癌细胞膜磷脂变化与蛋白激酶C同功酶表达对肝转移的影响

目的 :探讨结直肠癌细胞膜磷脂变化与蛋白激酶C(PKC)同功酶表达的关系及对肝转移的影响。方法 :采用高效液相色谱法 ,检测大肠癌原发灶、癌旁肠黏膜、肝转移灶细胞膜磷脂酰肌醇 (PI)、磷脂酰丝氨酸(PS)、磷脂酰乙醇胺 (PE)和磷脂酰胆碱 (PC)。采用QRT -PCR方法检测PKC -α -ε- ζ同功酶mRNA的表达。结果检测 4 8例大肠癌标本。在癌原发灶、肝转移灶中 ,PI、PE、PC含量高于癌旁肠黏膜组织 (P <0 .0 1)。肝转移灶与原发灶相中PI、PC含量无显著性差异 (P >0 .0 5 ) ,PE含量显著高于癌原发灶 (P <0 .0 1)。癌原发灶和肝转移灶中PKC -ε、- ζ表达高于癌旁肠黏膜组织 (P <0 .0 1) ,PKC -α表达水平降低。PE含量与PKC -ε、- ζ表达成正比 ,与肝转移呈正相关。PKC -α表达与PE含量成反比 ,与肝转移呈负相关。结论 :细胞膜磷脂PE含量升高 ,PKC -ε、- ζ增强表达和PKC -α表达水平降低与结直肠癌肝转移有密切关系。     

干扰素治疗慢性丙型肝炎中疗效预测因素的研究

目的:通过检测干扰素抗体、HCV 基因分型、治疗前后血清 HCV-RNA 量及淋巴细胞亚群,探讨干扰素疗效的预测因素.方法:ELISA 方法检测干扰素抗体,抗病毒中和生物鉴定法进行干扰素中和抗体检测.用 MTT 检测干扰素中和抗体的滴度.进行 HCV 基因分型及血清 HCV-RNA 定量检测.采用 APAAP 免疫桥联酶标法检测 T 淋巴细胞亚群.结果:(1)HCV-Ⅲ型感染者完全应答率较 HCV-Ⅱ型高,P＜0.05.(2)完全应答组治疗前血清 HCV-RNA 量明显低于部分应答和无应答组.(3)部分应答组干扰素抗体阳性率明显高于完全应答组,P＜0.05.中和抗体对干扰素疗效的影响与抗体的滴度有关,抗体滴度高干扰素疗效差.(4)各组间淋巴细胞亚群变化无统计学差异.结论:(1)治疗前血清 HCV-RNA 低水平是对干扰素治疗产生完全应答的一个重要的预测指标.(2)HCV-Ⅲ型患者对干扰素治疗的完全应答率明显高于 HCV-Ⅱ型.但可能受血清 HCV-RNA 水平的影响.(3)干扰素抗体,特别是中和抗体是影响干扰素疗效的因素之一,治疗过程中检测干扰素抗体是预测干扰素疗效的指标之一.(4)外周血淋巴细胞亚群不能作为预测干扰素疗效的指标.
