Methods for treating cancer, e.g., cancer of epithelial origin, by specifically targeting human satellite II (HSATII) using sequence specific agents such as oligonucleotides. As shown herein, the hetero chromatic HSATII satellite repeat is silenced in normal cells, but massively over expressed in epithelial cancers and in cancer cell lines when grown as xenografts or in 3D culture. Induction of HSATII RNA, either in xenografts or using in vitro reconstitution models, suggests the appearance of complementary DNA intermediates.
使用序列特异性制剂(如寡核苷酸)特异性靶向人类卫星 II(H
SATII)治疗癌症(如上皮源性癌症)的方法。如本文所示,异色 H
SATII 卫星重复序列在正常细胞中沉默,但在上皮癌中以及在异种移植或三维培养的癌
细胞系中大量过度表达。无论是在异种移植中还是使用体外
重组模型诱导 H
SATII RNA,都表明出现了互补 DNA 中间体。
