Antisense-mediated exon skipping is currently in clinical development for Duchenne muscular dystrophy (DMD) to amend the consequences of the underlying genetic defect and restore dystrophin expression. Due to turnover of compound, transcript, and protein, chronic treatment with effector molecules (antisense oligonucleotides) will be required. To investigate the dynamics and persistence of antis...
RNA antagonists using locked nucleic acid (LNA) antisense oligonucleotides are among the most promising therapeutics to treat cancer. Unlike the other antisense oligonucleotides, LNA-based oligonucleotides have high target binding affinity and long tissue stability. LNA can inhibit the mRNA expression at nanomolar and subnanomolar concentrations in the presence of lipofectamine. However, system...
Antisense oligonucleotides made of 2'-OMe RNA are shown to bind specifically and efficiently to targeted sites on pre-mRNA substrates, allowing affinity selection of splicing complexes using streptavidin/biotin chromatography. The position of probe binding to the pre-mRNA influences which type of splicing complex can be selected. The accessibility of pre-mRNA sequences to antisense probes chang...
Th e high effi ciency of baculovirus infection is partially explained by the ability of the virus to suppress host defense machinery connected with the apoptosis pathway. Members of the baculovirus gene family, inhibitors of apoptosis (vIAPs), have been shown to inhibit apoptosis in baculovirus-infected cells. Here we showed that treatment of the LdMNPV-infected 1st instar gypsy moth (Lymantria...
Minimally modified oligonucleotides belong to the second-generation antisense class. They are phosphodiester oligonucleotides with a minimum of phosphorothioate linkages in order to be protected against serum and cellular exonucleases and endonucleases. They activate RNase H, have weak interactions with proteins, and have thus a better antisense efficiency. Two of them have been designed from a...
Erythropoietin (epo) is the primary regulator of the rate of red blood cell formation in mammals. Because it is formed in the kidney and acts on the bone marrow, its action is classically endocrine. We have shown by PCR that marrow cells contain epo mRNA and that antisense oligodeoxynucleotides, to both epo and its receptor, act on multipotent hematopoietic cells to cause a decrease in mixed er...
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....
Baculovirus IAP (inhibitor-of-apoptosis) genes originated by capture of host genes. Unmodified short antisense DNA oligonucleotides (oligoDNAs) from baculovirus IAP genes can down-regulate specific gene expression profiles in both baculovirus-free and baculovirus-infected insects. In this study, gypsy moth (Lymantria dispar) larvae infected with multiple nucleopolyhedrovirus (LdMNPV), and LdMNP...
