  • Publication number: 20190248854
    Abstract: Methods for modifying a dystrophin gene are disclosed, for restoring dystrophin expression within a cell having an endogenous frameshift or nonsense mutation within the dystrophin gene. The methods comprise introducing a first cut within an exon en or intron of the dystrophin gene creating a first exon end or intron end, wherein said first cut is located upstream of the endogenous frameshift or nonsense mutation; and introducing a second cut within an exon or intron of the dystrophin gene creating a second exon end or intron end, wherein said second cut is located downstream of the frameshift or nonsense mutation. Upon joining/ligation of said first and second exon ends or intron ends a hybrid exon or intron junction is created and dystrophin expression is restored, as the correct reading frame is restored. Reagents and uses of the method are also disclosed, for example to treat a subject suffering from muscular dystrophy.

  • Patent number: 10280419
    Abstract: Methods and products are described related to use of the CRISPR/Cas9 system to introduce a modification into an APP gene, such as guide RNAs and recombinant proteins, for decreasing amyloid beta peptide produced by a cell. Also described are uses of such methods and products for the treatment of Alzheimer's disease and/or age-related cognitive decline in a cell from a subject in need thereof.

  • Publication number: 20130324545
    Abstract: AKR1B1 (EC 1.1.1.21) is an aldose reductase that has mainly been associated with the polyol pathway, and more recently with lipid deperoxidation. We have discovered that the primary activity of this enzyme is rather a PGFS activity, catalyzing the transformation of PGH2 into PGF2?. AKR1B1 as a therapeutic target, and method for modulating its expression and activity are provided. Methods for regulating the expression and activity of PGF2? are also provided.
