目的研究H-ran基因在乳腺癌转移中的作用及作为预测乳腺癌转移潜能指标的价值。方法采用免疫组织化学LSAB法观察76例乳腙癌、34例淋巴结转移灶和8例乳腺纤维腺瘤组织中p21蛋白、PCNA、CD44、ⅧRAg的表达情况;采用PCR—RFLP法检测42例乳腺癌、6例乳腺纤维腺瘤H—l'aS 12位密码子点突变状态。结果76例乳腺癌D2l蛋白阳性58例,有淋巴结转移组阳性率明显高于无转移组,2组比较有显著性差异(P<0.05)。p2l蛋白与CIN4、PCNA表达均呈正相关(7=0.6337,P<0 Ol;0.3044,P<0 05)。p2l蛋白阳性组肿瘤问质血管密度(IMVD)明显高于阴性组,2组比较有非常显著性差异(P<0.06)。结论p21蛋白表达与乳腙癌淋巴结转移密切相关;与CD44、IMVD联合检测可作为预测乳腙癌转移潜能敏感且准确的指标。

【期刊论文】miRNA-135a promotes breast cancer cell migration and invasion by targeting HOXA10
马端, . Chen YT, Zhang J, Wang HJ, Xu C, Du YY, Luo X, Zheng FY, Zhao JY, Zhang HW, Ma D*
BMC Cancer,-0001,():
Background: miRNAs are a group of small RNA molecules regulating target genes by inducing mRNA degradation or translational repression. Aberrant expression of miRNAs correlates with various cancers. Although miR-135a has been implicated in several other cancers, its role in breast cancer is unknown. HOXA10 however, is associated with multiple cancer types and was recently shown to induce p53 expression in breast cancer cells and reduce their invasive ability. Because HOXA10 is a confirmed miR-135a target in more than one tissue, we examined miR-135a levels in relation to breast cancer phenotypes to determine if miR-135a plays role in this cancer type. Methods: Expression levels of miR-135a in tissues and cells were determined by poly (A)-RT PCR. The effect of miR-135a on proliferation was evaluated by CCK8 assay, cell migration and invasion were evaluated by transwell migration and invasion assays, and target protein expression was determined by western blotting. GFP and luciferase reporter plasmids were constructed to confirm the action of miR-135a on downstream target genes including HOXA10. Results are reported as means ± S.D. and differences were tested for significance using 2-sided Student\"s t-test. Results: Here we report that miR-135a was highly expressed in metastatic breast tumors. We found that the expression of miR-135a was required for the migration and invasion of breast cancer cells, but not their proliferation. HOXA10, which encodes a transcription factor required for embryonic development and is a metastasis suppressor in breast cancer, was shown to be a direct target of miR-135a in breast cancer cells. Our analysis showed that miR-135a suppressed the expression of HOXA10 both at the mRNA and protein level, and its ability to promote cellular migration and invasion was partially reversed by overexpression of HOXA10. Conclusions: In summary, our results indicate that miR-135a is an onco-miRNA that can promote breast cancer cell migration and invasion. HOXA10 is a target gene for miR-135a in breast cancer cells and overexpression of HOXA10 can partially reverse the miR-135a invasive phenotype.

目的:观察2周期大剂量化疗方案联合自体外周血干细胞移植(D-HDC)治疗转移性乳腺癌的疗效及其安全性。方法:将28例转移性乳腺癌患者分为2个组。D-HDC组预处理方案:多西紫杉醇(DXL)110~130 mg/m2+ 噻替哌(THPA)300~400mg/m2+ 卡铂(CBP)650~750mg/m2,预处理后第2天回输外周血干细胞,间隔3~5周重复,共治疗2个周期;S-HDC组预处理方案:DXL 110~130mg/m2+ THPA 350~450mg/m2+ CBP 750~950mg/m2,预处理后第2天回输外周血干细胞,治疗1个周期。分别评价2组肿瘤客观缓解率和治疗相关的不良反应。结果:D-HDC组和S-HDC组的客观缓解率分别为66.7%(10/15),54.5%(6/11);2组白细胞毒性相近,但D-HDC组血小板毒性较低,Ⅲ~Ⅳ度发热,恶心呕吐,腹泻和黏膜炎的发生例数较少。结论:D-HDC 治疗转移性乳腺癌客观缓解率较高,血小板毒性较轻,Ⅲ~Ⅳ度非血液学毒性发生例数较少,患者耐受性良好。

背景与目的:乳腺癌的早期诊断是取得满意治疗效果的关键,目前临床常用的乳腺癌检查方法有近红外线乳腺扫描,乳腺x线钼靶及数字化摄片、针吸细胞学检查、乳腺穿刺活检、外科手术活检或冰冻切片检查等,但这些方法的检测出来的多数已非早期肿瘤。本研究就是应用蛋白质芯片技术,分析乳腺癌患者与乳腺非癌患者和正常妇女、I期、Ⅱ期和Ⅲ期乳腺癌之间血清蛋白质表达的差异。方法:我们选择IMAC3和WCX2两种芯片,对64例乳腺癌、52例乳腺非癌患者及12名正常妇女血清进行研究。统计学分析采用CiPhergen ProteinChiP3.0和Biomark Wizard软件分析乳腺癌、乳腺非癌患者和正常人血清的蛋白质谱差异。结果:在WCX-2蛋白芯片,分子量为9116DA、8905DA、8749DA、9470DA和9692Da的5个位点,在乳腺癌患者与乳腺非癌患者及正常妇女血清之间WCX-2蛋白峰表达有差异,乳腺癌患者蛋白质峰的表达较乳腺非癌和正常妇女表达高,敏感性为54.75%~92.2%;特异性为53.1%~81.3%;分子量为9 405Da和6 424Da的2个位点,I期乳腺癌与Ⅲ期乳腺癌患者血清蛋白峰表达有差异。敏感性为73.7%~78.9%。特异性为61.9%~71.4%。在IMAC3蛋白芯片,分子量分别为5236DA、7823DA、7464DA、5213DA、5334DA、5063DA、5374DA、7756Da和7623Da有9个位点位置,乳腺癌患者与乳腺非癌患者及正常妇女血清蛋白峰表达有差异,蛋白质峰的表达乳腺癌患者较乳腺非癌和正常妇女表达低,敏感性为56.3%~2.8%。特异性为48.4%~78.1%;分子量为7922Da、4641Da和5910Da位置,Ⅰ期乳腺癌与Ⅲ期乳腺癌患者血清蛋白峰表达有差异,敏感性为63.2%~84.2%。特异性为47.6%~66.7%。结论:乳腺癌患者与乳腺非癌及正常妇女血清蛋白峰表达存在差异,这些差异蛋白有可能成为新的乳腺癌分子标志物,有助于乳腺癌的早期诊断及术后的随访。

为探讨乳腺癌发病与有机氯农药污染的关系,采片分阶段整群随机抽样的方法,按乳腺癌标化发病率高低抽取11个乡镇,再随机抽取行政村、自然村,测定再乡镇大米和土壤样品中有机氯各指标的含量,结台各乡镇的乳腺癌发病资料,进行统计分析结果表明,各乡镇的乳腺癌标化发病率存在统计学显著性差异;大米中&-HcH、y-HcH、五氯酚钠以及土壤的&-HcH含量在各乡镇间有显著性差异;乳腺癌标化发病率与大米中PP'-DDD含量呈负相关,相关系数为-0.609,说明经过近20年的降解过程,DDT的衍生物含量最终以PP'-DDD居多,并且乳腺癌标化发痛率与大米中PP'-DDD含量呈负相关。
