Insertion of variant exons of CD44 gene of cancer stem cells into its mRNA is inhibited whereupon the cancer stem cells lose their properties so that they are rendered sensitive to anticancer agents and radiation, possibly leading to cancer treatment.
A drug for cancer treatment, comprising an antisense oligonucleotide capable of inducing skipping of variant exon(s) of CD44 gene to thereby increase expression of normal CD44 mRNA, a pharmaceutically acceptable salt thereof, a solvate thereof or a prodrug thereof. An oligonucleotide of 20-23 bp having the entirety or a part of any one of the nucleotide sequences as shown in SEQ ID NOS: 1 to 19, a pharmaceutically acceptable salt thereof, a solvate thereof or a prodrug thereof. A drug for inducing skipping of at least one variant exon selected from the group consisting of variant exons 8, 9 and 10 of CD44 gene, comprising the above-described oligonucleotide, a pharmaceutically acceptable salt thereof, a solvate thereof or a prodrug thereof.
癌症干细胞CD44基因的变异外显子插入其mRNA的过程受到抑制,从而使癌症干细胞失去其特性,使其对抗癌剂和辐射敏感,可能导致癌症治疗。
一种治疗癌症的药物,包括能够诱导跳过 CD44 基因变异外显子从而增加正常 CD44 mRNA 表达的反义寡核苷酸、其药学上可接受的盐、其溶液或其原药。具有 SEQ ID NOS: 1 至 19 中所示核苷酸序列的全部或部分的 20-23 bp 的寡核苷酸、其药学上可接受的盐、其溶液或其原药。一种用于诱导至少一个选自 CD44 基因变异外显子 8、9 和 10 所组成的组中的变异外显子的跳过的药物,包括上述寡核苷酸、其药学上可接受的盐、其溶液或其原药。
