INHIBITOR OLIGONUCLEOTIDES AND THEIR USE FOR SPECIFIC REPRESSION OF A GENE ENCODING AN ANDROGEN RECEPTOR |
摘要 |
Double-stranded oligonucleotides (I) consisting of two complementary strands (Ia; Ib), each having at one of their 3' and 5' ends 1-5 unpaired nucleotides, forming single-stranded overhangs, are new. One of (Ia) and (Ib) is complementary to a target sequence, of DNA or RNA, that is to be specifically repressed. ACTIVITY : Cytostatic; Virucide; Anti-HIV; Neuroprotective; Ophthalmological; Antidiabetic; Antipsoriatic; Antirheumatic; Antiarthritic. The oligonucleotide hybrid (A) prepared from sequences of formulae ggggaggcagccauugagacTT gucucaauggcugccuccccTT (lower case indicates ribonucleotides and upper case deoxyribonucleotides) was designed to target the junction of the PML/RARalpha fusion gene associated with promyelocytic leukemia. It (500 ng) was introduced into NIH 3T3 cells, co-transfected with a vector (100 ng) that expressed the PML/RARalpha fusion. Western blotting analysis after 48 hours showed greatly reduced expression of the fusion protein, relative to a control without (A). MECHANISM OF ACTION : Antisense inhibition of gene expression. |
