Abstract: The invention generally relates to compositions and methods for targeted delivery of a Cas endonuclease or nucleic acid encoding a Cas endonuclease to a fusion sequence in a cancer cell but not in a healthy cell of a subject. The Cas endonuclease or nucleic acid encoding the Cas endonuclease may be complexed with a guide RNA complementary to a fusion sequence identified based on differences between a mutated sequence obtained from a cancer cell and a wild-type sequence obtained from a healthy cell of the subject. For example, the Cas endonuclease may be a Cas9 and cut DNA or a Cas13a and cut RNA. The Cas endonuclease complexes may induce cell death or cancerous cells or cause other beneficial effects.
Abstract: A method to prevent, inhibit or treat one or more symptoms associated with a disease of the central nervous system by intrathecally, intracerebroventricularly or endovascularly administering a rAAV encoding a gene product associated with the disease, e.g., a mammal in which the gene product is absent or present at a reduced level relative to a mammal without the disease.

Disclosed herein is a previously unknown, essential component of the Wnt/?-catenin signaling pathway that governs the quantity of ?-catenin delivered to the cell nucleus. This intracellular inhibitor of ?-catenin signaling (IBS) is transcribed from a second transcriptional start site adjacent to exon 3 of the Dkk3 gene and is required for early mouse development. IBS captures ?-catenin destined for the nucleus in a complex with ?-TrCP that is bound to the actin cytoskeleton and unavailable for nuclear translocation.
