Objective To sequence follicle stimulating hormone receptro (FSHR) promoter of the ovarian granulocyte and initially research the molecular mechanism of the poor ovarian response. Methods To study the relationship between FSHR promoter mutation of ovarian granulocyte and ovarian respone. The 263 bp DNA fragments before FSHR 5'initiation site in 70 cases of patients with poor ovarian respone and 88 cases of patients with ovarian normal respone who were in the cycle of IVF-ET were sequenced, Results There were 63 cases which occurred 29th site G → A point mutation in 158 women and the mutation rate was 40. 0%. Mutation rate [ 60. 0% ( 42/70 ) ] of 29th site G → A in group of poor ovarian respone was significantly higher(χ2 = 21. 450,P < 0. 01 ) than normal response group [ 23.9% ( 21/88 ) ]. There was no obviously variability ( t = 0. 457, P 0. 05 ) of basic FSH values between two groups [ G/G group was (7.2 ± 2. 3) U/L, G/A & A/A group was (7. 1±2. 0) U/L];there was obviously variability (t = 35. 81 ,P < 0. 05 ) in the number of follicles sinus between two groups ( G/G group was 14. 2±1.3, G/A & A/A group was 4. 5±0. 8 ) ;there was obviously variability ( t = 40. 35, P < 0. 05 ) in the number of ovum pick-up between two groups ( G/G group was 14. 0±1.2, G/A & A/A group was 4. 5±1.1 ) ;there was obviously variability (t =25. 80,P <0.05) of FE2-peak value between two groups [G/G group was (2 865±557) pmol/L, G/A & A/A group was (880±211 ) pmol/L] ;there was obviously variability (t =40. 22 ,P <0. 05) in the number of mature eggs ( G/G group was 13.6±1.2, G/A&A/Agroupwas4.3±0. 9).Conclusion The 29th site of FSHR promoter significantly affect the activity of FSHR promoter. Mutation of G→A can weaken promoter activity, so that ovarian granulocyte poor respone to FSH.  相似文献

端粒酶与PCNA在子宫内膜癌中表达的研究   总被引:1,自引:0,他引:1  
目的探讨端粒酶与PCNA在宫内膜癌中表达临床价值。方法采用原位杂交和免疫组化方法检测内膜标本的端粒酶和PCNA的表达。结果①PCNA在正常内膜和癌组织中均存在,其表达程度与病理分级及临床分期有关。②端粒酶在正常子宫内膜和癌组织中表达率分别为10%和80.56%。差异有显著性。③PCNA的表达与端粒酶表达具有高度相关性。结论①端粒酶活化与子宫内膜癌的发生发展有密切关系,可望成为内膜癌早期临床诊断和判断预后的标志物;②端粒酶的激活导致PCNA的增殖,RCNA联合端粒酶可以判断患者的预后。  相似文献

目的 初步探讨颗粒细胞卵泡刺激素受体(FSHR)启动子-29位点突变后的表达改变与卵巢反应性的关系.方法 对体外受精-胚胎移植(IVF)周期中35例卵巢反应不良患者与15例卵巢正常反应患者FSHR 5'端起始位点的前263 bp DNA片段进行测序;收集采卵日获得的卵泡颗粒细胞, 检测FSHR的表达水平.结果 50例患者中有26例发生-29位点G→A突变, 其中4例为杂合子, 22例为纯合子, 24例测序结果 无突变, 突变的发生率为52%.-29位点基因正常组、杂合突变组及纯合突变组的FSHR表达强度依次为26.33±5.11、18.01±6.72和13.78±2.29, 三组两两比较均差异有统计学意义(P<0.01).结论 FSHR启动子的-29位点突变导致FSHR产生不足, 最终导致患者对FSH的低反应性.  相似文献

目的:探讨DNA甲基转移酶抑制剂5-氮-2'-脱氧胞苷对子宫内膜异位症大鼠模型异位灶的影响。方法:根据大鼠自体移植方法构建大鼠子宫内膜异位症模型。4周后二次开腹判断造模是否成功,用游标卡尺测量记录异位灶体积后将大鼠随机分为实验组(n=12)、磷酸盐缓冲液(PBS)组(n=12)和对照组(n=11),同时选取未造模的正常大鼠作为空白组(n=10)。实验组大鼠腹腔注射5-氮-2'-脱氧胞苷(2.5 mg/kg·d),PBS组注射等量PBS溶液对照组和空白组未用药。4周后取大鼠腹腔冲洗液及异位灶标本后处死大鼠,再次用游标卡尺测量备组异位灶体积大小。异位灶组织常规HE切片后显微镜下观察组织形态结构。应用免疫组织化学染色方法和Western Blot法检测备组异位灶内DNA甲基转移酶1(DNMT1)的表达情况。收集腹腔冲洗液用Elisa法检测肿瘤坏死因子(TNF-α)含量。结果:①50只大鼠根据大鼠子宫内膜自体移植方法成功35例,造模成功率为70%(35/50)。②实验组大鼠经药物处理后异位灶体积明显缩小(处理前后病灶体积分别为51.08±12.73 mm~3和5.56±3.68 mm~3),差异有统计学意义(P0.01)。③免疫组化检测实验组、PBS组、对照组异位灶组织中DNMT1表达的组织学评分分别为2.30±0.97分、3.80±1.77分、4.07±1.92分;Western Blot法检测实验组、PBS组、对照组异位灶组织中DNMT1蛋白的相对表达量分别为0.17±0.39、0.29±0.17、0.3 1±0.41。实验组异位灶组织中DNMT1表达低于PBS组及对照组差异有统计学意义(P0.05)。④实验组大鼠腹腔冲洗液中TNF-α含量较PBS组及对照组降低,实验组、PBS组、对照组均较空白组均升高差异有统计学意义(P0.05)。结论:DNA甲基转移酶抑制剂能明显减少异位灶中DNMT1的表达及腹腔冲洗液中TNF-α含量,缩小异位灶体积,促进异位灶萎缩,为子宫内膜异位症的靶向治疗提供了依据。  相似文献
