用於癌症研究的經認證乳癌細胞株

乳癌是婦女第二大常見癌症,也是癌症致死的主要原因之一。 它起初是局部腫瘤,但可轉移至遠處部位並導致死亡。乳癌具有異质性,為診斷和治療帶來挑戰。特別具挑戰性的是所謂的三陰性乳癌,也就是腫瘤不表達與乳癌生長最密切相關的三種受體-雌激素、孕激素和 HER-2/neu,並且對任何荷爾蒙療法都無反應的乳癌1

乳癌的類型

乳腺管癌和乳腺小葉癌是乳癌的兩種類型,因其起源組織而得名。根據受體的存在,可分為荷爾蒙受體陽性、HER2 陽性和三重陰性乳癌。

風險因素

年齡是乳癌的主要風險因素,發病率隨著年齡增長而增加。年輕時月經期暴露於雌激素的機會增加,以及年紀較大時首次懷孕,也是其他重要的危險因素2

突變

乳癌中常見的突變基因包括 PIK3CA, TP53MED12GATA3< 和 PTEN。然而,在 BRCA2 ;家族遺傳性乳癌病例中有一半是由這些突變引起的,此外,攜帶這些突變的人罹患其他惡性腫瘤(包括卵巢癌)的風險也較高。

從下表中按基因突變選擇細胞系,然後點擊基因,為您的研究找到相關產品(抗體、shRNA、siRNA、引物、CRISPR質粒)。

小分子化合物/單株抗體

小分子化合物和抗體可用於靶向癌細胞,阻斷腫瘤生長和惡化。根據腫瘤的階段和類型,有多種小分子化合物和抗體可以針對乳癌。

乳癌靶向藥物的種類包括:

  • 單株抗體 (Trastuzumab, Pertuzumab)
  • 酪氨酸激酶抑制劑 (拉帕替尼
  • Palbociclib, Ribociclib)
  • mTOR抑制劑 (Everolimus) 。

此外,研究聚 ADP 核糖聚合酶 (PARP 抑制劑正在針對三重陰性乳癌3進行研究。

應用

癌症細胞系是癌症研究的基礎。由於它們易於使用且成本效益高,因此已被廣泛用於無數的研究中。根據細胞株的特性和實驗需要,細胞株可以用於一種或多種應用。
