Abstract: Disclosed are oligonucleotides which target and hybridize to nucleic acid molecules encoding A TXNJ, leading to reduced expression of ATXN3. Reduction in the expression of aberrant ATXN3 is beneficial for the treatment of certain medical disorders, such as spinocerebellar ataxia 3. In particular embodiments, modulating the expression of an aberrant A TXN3 allele or transcript, for example, restores normal function of, for example, Purkinje cells or spinal cord neurons. The oligonucleotides of the present invention and the methods of using such oligonucleotides to modulate the expression of aberrant or expanded A TXN3 provide a means of improving the survival and morbidity associated with, or even curing, expression of an aberrant A TXN3 allele or transcript such as, for example, spinocerebellar ataxia-type 3 (SCA3).

Abstract: The present invention relates to compositions and methods for preparing splice variants of TNFalpha receptor (TNFR) in vivo or in vitro, and the resulting TNFR protein variants. Such variants may be prepared by controlling the splicing of pre-mRNA molecules and regulating protein expression with splice switching oligonucleotides or splice switching oligomers (SSOs). The preferred SSOs according to the invention target exon 7 or 8 of TNFR1 (TNFRSF1A) or TNFR2 (TNFRSF1A) pre-mRNA, typically resulting in the production of TNFR variants which comprise a deletion in part or the entire exon 7 or 8 respectfully. SSOs targeting exon 7 are found to result in a soluble form of the TNFR, which has therapeutic benefit for treatment of inflammatory diseases. The SSO's are characterized in that they are substantially incapable or incapable of recruiting RNaseH.

Abstract: The invention provides pharmaceutical compositions comprising short single stranded oligonucleotides, of length of between 8 and 26 nucleobases which are complementary to human microRNAs selected from the group consisting of miR19b, miR21, miR122a, miR155 and miR375. The short oligonucleotides are particularly effective at alleviating miRNA repression in vivo. It is found that the incorporation of high affinity nucleotide analogues into the oligonucleotides results in highly effective anti-microRNA molecules which appear to function via the formation of almost irreversible duplexes with the miRNA target, rather than RNA cleavage based mechanisms, such as mechanisms associated with RNaseH or RISC.
