Antisense oligonucleotides for neurodegeneration

Radiolabeled oligonucleotides for antisense imaging.

Oligonucleotides radiolabeled with isotopes emitting γ-rays (for SPECT imaging) or positrons (for PET imaging) can be useful for targeting messenger RNA (mRNA) thereby serving as non-invasive imaging tools for detection of gene expression in vivo (antisense imaging). Radiolabeled oligonucleotides may also be used for monitoring their in vivo fate, thereby helping us better understand the barrie...

Designing Antisense Oligonucleotides

Antisense oligonucleotides have been used for a number of years to modify the expression of specific genes both in vivo and in vitro (Scanlon et al., 1995). The most potent mode of antisense activity is through RNase H–mediated degradation of RNA (Figure 1). The RNase H– endonuclease specifically cleaves RNA only when it is hybridized as a heteroduplex with DNA. In general, oligonucleotides tha...

Meeting report: antisense oligonucleotides.

The use of antisense oligonucleotides as a therapeutic tool in modulating gene expression represents a newly established strategy for treating diseases. Such oligomers may be designed to complement a region of a specific gene or messenger RNA. Using this approach, oligonucleotides can serve as a potential block of transcription or translation through sequence-specific hybridization with targete...
