Abstract
本研究主要目的是探討PRIM1(primase, DNA, polypeptide 1)與乳癌的關聯性。主要是由於先前文獻利用細胞微晶片去篩選出與癌症相關的基因來尋找出治療的標誌,從中發現PRIM1在乳癌細胞中大量的表現,而此研究也並未有進一步深入的探討。本論文主旨“探討PRIM1在乳癌中扮演的角色與影響癌症的變化”。本研究透過乳癌細胞和乳癌病人的檢體來探討PRIM1在乳癌中的機轉與作用。首先,利用RT-PCR和Real-time PCR分別在八株乳癌細胞株與254名乳癌病人檢體上互相檢測,觀察到無論是在細胞株或是病人檢體中,PRIM1都會大量表現在乳癌之中。之後,利用IHC染色來判斷PRIM1基因在乳癌組織上表現的量與位置,在腫瘤部分有表現較高比例的PRIM1。另一方面,使用siRNA來調控PRIM1基因的表現,觀察對於乳癌細胞株影響,進一步了解PRIM1在乳癌中的調控機制。並找出可以抑制乳癌細胞中PRIM1表現的天然藥物,進而降低乳癌的發生,希望未來可以更深入的探討PRIM1在乳癌中的機轉並配合天然藥物,期望可改善乳癌病患的治療或降低發生率。同時利用ChIP assay 來探討是那些重要的轉錄因子會因Nicotine 或 Estrogen 的刺激下而調控PRIM1的表現,並進一步研究此調控中誰扮演重要角色。更了解此基因在乳癌的重要性。希望對未來治療乳癌病患可以有多一些的貢獻。
