Retroviruses display a strong selective pressure to maintain the dimeric nature of their genomic RNAs, suggesting that dimerization is essential for viral replication. Recently, we identified the cis-element required for initiation of human immunodeficiency virus type I (HIV-I) RNA dimerization in vitro. The dimerization initiation site (DIS) is a hairpin structure containing a self-complementa...
The use of splice-switching antisense therapy is highly promising, with a wealth of pre-clinical data and numerous clinical trials ongoing. Nevertheless, its potential to treat a variety of disorders has yet to be realized. The main obstacle impeding the clinical translation of this approach is the relatively poor delivery of antisense oligonucleotides to target tissues after systemic delivery....
A wide variety of modified oligonucleotides have been tested as antisense agents. Each chemical modification produces a distinct profile of potency, toxicity, and specificity. Novel cationic phosphoramidate-modified antisense oligonucleotides have been developed recently that have unique and interesting properties. We compared the relative potency and specificity of a variety of established ant...
Patients affected by cerebral gliomas, despite classical strategies adopted, show a very poor prognosis. Current treatment consists of regimens that include surgical debulking, radiation therapy, and systemic chemotherapy. However, the median survival after surgery and radiation therapy alone is 9 months, and systemic chemotherapy is minimally effective. Advances in molecular biology have bette...
Synthetic antisense oligonucleotides have been used to inhibit specific protein synthesis in vivo. Antisense oligonucleotides directed to kinesin heavy chain were injected into the vitreous of anesthetized rabbits in order to assess the effects on transport in the retinal ganglion cells whose axons form the optic nerve. The antisense oligonucleotide specifically inhibited retinal kinesin synthe...
A biological reporter gene assay was employed to determine the crucial parameters for maximizing selective targeting of a Ha-ras codon 12 point mutation (G----T) using phosphorothioate antisense oligonucleotides. We have tested a series of oligonucleotides ranging in length between 5 and 25 bases, each centered around the codon 12 point mutation. Our results indicate that selective targeting of...
