  • Publication number: 20130178511
    Abstract: The present invention provides compositions comprising nucleic acids that target CSN5 gene expression and methods of using such compositions to silence CSN5 gene expression. More particularly, the present invention provides unmodified and chemically modified interfering RNA molecules which silence CSN5 gene expression and methods of use thereof, e.g., for treating cell proliferative disorders such as cancer. The present invention also provides nucleic acid-lipid particles that target CSN5 gene expression comprising an interfering RNA molecule, a cationic lipid, a non-cationic lipid, and optionally a conjugated lipid that inhibits aggregation of particles.

  • Publication number: 20100129791
    Abstract: Nucleic acids that encode novel polypeptides, designated in the present application as “BOG” (B5T Over-expressed Gene) are provided. BOG binds to pRb and is over-expressed in a number transformed rat liver epithelial (RLE) cell lines resistant to the growth inhibitory effect of TGF-?1 as well as in primary liver tumors. Compositions including BOG chimeras, nucleic acids encoding BOG and antibodies to BOG are also provided. Methods of using BOG to modulate pRb-protein interactions and to alter cellular phenotype are further provided.

  • Publication number: 20090239220
    Abstract: A cDNA molecule corresponding to a newly discovered human gene is disclosed. The new gene, which is frequently deleted in liver cancer cells and cell lines, is called the DLC-1 gene. Because the gene is frequently deleted in liver cancer cells, but present in normal cells, it is thought to act as a tumor suppressor. This gene is also frequently deleted in breast and colon cancers, and its expression is decreased or undetectable in many prostate and colon cancers. Also disclosed is the amino acid sequence of the protein encoded by the DLC-1 gene. Methods of using these biological materials in the diagnosis and treatment of hepatocellular cancer, breast cancer, colon cancer, prostate cancer, and adenocarcinomas are presented.

  • Patent number: 5081584
    Abstract: A computer-implemented method for designing at least one anti-peptide sequence having affinity for target peptide or a fragment thereof suitable for synthesizing peptides and micromolecules, assaying for a target peptides, purifying target peptides, and/or preventing proteolyis of a polypeptide includes identification of the members of the amino acid sequence of the target peptide and their anti-sense or hydropathically complementary amino acids and determining the moving average hydropathy for the target and anti-sense members. The resulting lowest hydropathy identifies the anti-sense amino acid sequence for the target peptide. The members of the target peptide amino acid sequence are obtained along with their member-specific hydropathic values with the hydropathic values summed as a moving average. Anti-sense or complementary amino acid members are identified from the moving average information to generate an array of anti-sense amino acid sequences.
