Abstract
至今,乳癌已成為全球女性癌症第二大死亡原因。根據世界衛生組織的統計,在2004年全球已約有120萬名婦女被診斷出乳癌。
有多篇研究報告指出,IGFBP-4(Insulin-like growth factor binding protein-4)廣泛分布於循環系統,且在攝護腺癌、大腸直腸癌及乳癌等多種癌細胞中IGFBP-4皆有表現。本研究先經由Real-time PCR方法比較癌組織與正常組織中IGFBP-4的表現差異,再利用ELISA實驗原理,對乳癌病人的血清進行IGFBP-4量的測量。以探討IGFBP-4在乳癌細胞的表現情形,與臨床運用的關聯 。
研究中,以乳癌病人的組織進行IGFBP-4於癌組織與正常組織的表現差異。經由Real-time PCR定量mRNA的表現量,發現IGFBP-4在癌組織的表現量比正常組織高50倍。乳癌經以往的研究報告被認為危險因子有基因遺傳、月經、暴露女性荷爾蒙的機會、社會型態的改變、飲食習慣、患有其他癌症等等。本實驗結果利用統計軟體配合乳癌病患的臨床病理資料(癌細胞分化程度、癌症分期、腫瘤大小等觀察因子)進行比對,在癌症分期情形,發現IGFBP-4的表現無論是real-time或是ELISA的實驗結果,兩者都呈現分期愈後期的表現愈高;癌細胞分化程度在分化不良(poor differentiation)的結果有表現趨勢。於是假設IGFBP-4的表現與乳癌是有關連。
