  • Publication number: 20180064744
    Abstract: Aspects of the invention include methods of reducing the deleterious activity of a mutant extended nucleotide repeat (NR) containing target gene in a cell by contacting the cell with an effective amount of a nucleoside agent, as well as compositions used in such methods. The deleterious activity (e.g., toxicity and/or dis-functionality of products encoded thereby) of a mutant extended NR containing target gene may be reduced in a variety of different ways, e.g., by reducing (and in some instances differentially, including selectively, reducing) the production or activity of toxic expression products (e.g., RNA or protein) encoded by the target gene. Kits and compositions for practicing the subject methods are also provided.

  • Patent number: 8404807
    Abstract: TSG101 is a tumor susceptibility gene whose homozygous functional knock out in fibroblasts leads to transformation and the ability of these cells to form metastatic tumors in nude mice. The cellular transformation that results from inactivation of TSG101 is reversible by restoration of TSG101 function. Decreased expression of TSG101 is associated with the occurrence of certain human cancers, including breast carcinomas. The TSG101 nucleic acid compositions find use in identifying homologous or related proteins and the DNA sequences encoding such proteins; in producing compositions that modulate the expression or function of the protein; and in studying associated physiological pathways. In addition, modulation of the gene activity in vivo is used for prophylactic and therapeutic purposes, such as treatment of cancer, identification of cell type based on expression, and the like.
