The present invention relates to methods of treating, preventing or managing intestinal fibrosis by inhibiting SMAD7. The invention is also directed to methods of monitoring effectiveness of treatment or management of intestinal fibrosis using a SMAD7 antisense oligonucleotide, as well as methods of regulating SMAD7 antisense oligonucleotide treatment, based on analysis of Transforming Growth Factor-β (TGF-β) levels, α-Smooth Muscle Actin (a-SMA) levels, and/or phosphorylated Mothers Against Decapentaplegic Homolog 3 (p-SMAD3) levels.

Polynucleotides, such as aptamers, comprising at least first one 5-position modified pyrimidine and at least one second 5-position modified pyrimidine are provided, wherein the first and second 5-position modified pyrimidines are different. Methods of selecting and using such polynucleotides, such as aptamers, are also provided.

The present invention relates to a method for decreasing the immunogenicity of an RNA molecule and/or at least maintaining the translation efficacy thereof. The present invention further relates to an RNA molecule, which is modified as compared to a corresponding wildtype RNA molecule, wherein the exchange of codons results in the total cytidine content of the modified RNA molecule being at least 10% less than the total cytidine content of the corresponding RNA molecule transcribed from said wildtype DNA sequence. The present invention also relates to an RNA molecule, wherein the exchange of codons results in the total uridine content of the modified RNA molecule being at least 10% less than the total uridine content of the corresponding RNA molecule transcribed from said wild-type DNA sequence. Finally, the present invention relates to the use of an RNA molecule of this invention in genome editing.

The current invention provides an improved oligonucleotide and its use for treating, ameliorating, preventing, delaying and/or treating a human cis-element repeat instability associated genetic neuromuscular or neurodegenerative disorder.

Disclosed herein are compositions that comprise engineered polynucleotides, pharmaceutical compositions comprising the same, methods of making the same, and methods of treatment comprising the compositions that comprise the engineered polynucleotides.

This invention provides a range of translatable polynucleotide and oligomer molecules for expressing a human amylo-alpha-1, 6-glucosidase, 4-alpha-glucanotransferase (AGL), or a fragment thereof having AGL activity. The polynucleotide and oligomer molecules are expressible to provide the human AGL or a fragment thereof having AGL activity. The molecules can be used as active agents to express an active polypeptide or protein in cells or subjects. The agents can be used in methods for ameliorating, preventing, delaying onset, or treating a disease or condition associated with reduced activity of amylo-alpha-1, 6-glucosidase, 4-alpha-glucanotransferase (AGL) in a subject.

Disclosed herein are compositions and compounds comprising modified oligonucleotides for modulating TMPRSS6 and modulating an iron accumulation disease, disorder and/or condition in an individual in need thereof. Iron accumulation diseases in an individual such as polycythemia, hemochromatosis or β-thalassemia can be treated, ameliorated, delayed or prevented with the administration of antisense compounds targeted to TMPRSS6.

A chimeric molecule resulting from fusion of a first nucleic acid or a derivative thereof, which has an ability to bind to a target nucleic acid, with a second nucleic acid or a derivative thereof, which has an ability to bind to the target nucleic acid, and in which a main chain skeleton. is anionic, a pharmaceutical composition containing the chimeric molecule, a method for cleaving a target nucleic acid using the chimeric molecule, and a kit for target nucleic acid cleavage or diagnosis including the chimeric molecule.
