摘 要:[目的] 观察Slug在基底细胞样乳腺癌(BLBC)中的表达情况及其与上皮间质转化(EMT)的关系。[方法] 依照免疫组化表型筛选出BLBC、管腔A、管腔B/C、Her-2过表达及正常乳腺样型共147例乳腺癌,采用EnVision两步法检测各亚型中Slug、E-cadherin、Vimentin及β-catenin的表达情况。[结果] 41例BLBC中Slug、Vimentin 阳性率分别为63.4%(26/41)和39.0%(16/41)。E-cadherin表达减弱率为63.4%(26/41)、β-catenin异常表达率为53.7%(21/41)。BLBC组中Slug、Vimentin阳性率高于其他各亚型(P<0.01)。BLBC组中Slug表达与E-cadherin表达减弱和Vimentin表达上调存在相关性(P<0.05)。BLBC组中Slug阳性表达与组织学分级、淋巴结转移相关。[结论] EMT可能是造成BLBC特殊生物学行为的原因,并且受Slug基因表达的调节。 |

Abstract: [Purpose] To investigate the expression of Slug in basal-like breast carcinoma(BLBC)and its relationship with epithelial-mesenchymal transition(EMT).[Methods] One hundred and forty-seven cases of breast cancers including BLBC,Luminal A,Luminal B,Her-2 overexpression and normal breast-like were enrolled based on immunophenotypes. The expression of Slug,E-cadherin,Vimentin and β-catenin were detected by immunohistochemistry.[Results] Slug and Vimentin positive rate in 41 cases of BLBC were 63.4%(26/41) and 39.0%(16/41) respectively. E-cadherin expression weakened in 26 cases(63.4%). β-catenin abnormal expression was observed in 21 cases(53.7%). The positive rates of Slug and Vimentin were higher in BLBC than those in other subtypes of breast cancer(P<0.01). Slug expression significantly related to E-cadherin reduced expression and Vimentin increased expression(P<0.05). Slug positive expression related to grade and lymph node metastasis in BLBC. [Conclusion] EMT might be the cause of special biologic behavior in BLBC and be regulated by expression of Slug. |
