  • Publication number: 20240141311
    Abstract: Disclosed herein are recombinant meganucleases engineered to bind and cleave a recognition sequence in the mitochondrial DNA (mtDNA) of a eukaryotic cell, such as a plant cell. The disclosure further relates to the use of such recombinant meganucleases in methods for producing genetically-modified eukaryotic cells, and to a population of genetically-modified eukaryotic cells wherein the mtDNA has been having modified or edited.

  • Publication number: 20240101986
    Abstract: The present invention encompasses engineered meganucleases which recognize and cleave a recognition sequence within the human PCSK9 gene. The present invention also encompasses methods for using such engineered meganucleases in a pharmaceutical composition and in methods for treating or reducing the symptoms of cholesterol-related disorders, such as hypercholesterolemia. Further, the invention encompasses pharmaceutical compositions comprising engineered meganuclease proteins, nucleic acids encoding engineered meganucleases, and the use of such compositions for treating cholesterol-related disorders, such as hypercholesterolemia.

  • Patent number: 7962998
    Abstract: A roller support assembly is used to support sliding doors, windows or the like. The assembly includes a housing member having spaced apart side walls and interconnecting transverse walls defining a roller receiving zone for receiving and operationally mounting a roller assembly. The roller assembly has a roller body with a rolling peripheral rim and a shaft whereby the roller body is rotatable relative to the shaft having short stub axle parts. The housing side walls including openings that are fully enclosed by the side walls into which the short stub axle parts fit. The housing side walls further include projecting elements extending inwardly from an inner surface of a housing side wall to cooperate with the corresponding roller body side wall surfaces to spay the housing side walls apart as the roller assembly is moved into the roller receiving zone to locate the stub axle parts in the openings.
