Aspects of the disclosure relate to complexes comprising a muscle-targeting agent covalently linked to a molecular payload. In some embodiments, the muscle-targeting agent specifically binds to an internalizing cell surface receptor on muscle cells. In some embodiments, the molecular payload inhibits expression or activity of DUX4. In some embodiments, the molecular payload is an oligonucleotide, such as an antisense oligonucleotide or RNAi oligonucleotide.

SARS-CoV-2 causes pandemic COVID19. Developing an effective treatment to directly target the virus could significantly impact viral burden in those most vulnerable to the devastating effects of this virus. The invention provides antisense oligonucleotides (AOs) to target the single stranded RNA genome of the SARS-CoV-2 viruses. The administration of AOs can significantly reduce the target viral RNAs.

The present invention provides an oligomer which efficiently enables to cause skipping of the 53rd exon in the human dystrophin gene. Also provided is a pharmaceutical composition which causes skipping of the 53rd exon in the human dystrophin gene with a high efficiency.

The present disclosure relates to antisense oligonucleotides (AONs), such as phosphorodiamidate morpholino oligonucleotides (PMOs). The present disclosure further relates to the conjugation of multiple PMOs to cationic cell penetrating peptides (CPPs) to enhance the uptake of PMOs into skeletal and cardiac muscle cells.

Methods of using B2 or Alu nucleic acids, or antisense oligonucleotides that modulate the EZH2/B2 or EZH2/Alu interaction and have the capacity to alter cleavage of B2 and Alu RNA, for increasing or decreasing cell and organismal viability.
