Abstract
The invention relates to a newly identified tumor suppressor gene, designated DOS (for Deleted in Osteosarcoma and alternatively referred to herein as DOCK 3) which has been cloned from human and mouse cells. The DOS nucleic acid and protein molecules and their use in the diagnosing and treating disorders characterized by aberrant DOS molecule expression are described.
Claims38
An isolated nucleic acid molecule selected from the group consisting of:
- (a) nucleic acid molecules which hybridize under stringent conditions to a nucleic acid molecule having a nucleotide sequence set forth as SEQ ID NO:1 or SEQ ID NO:3, and which code for a DOS protein,
- (b) deletions, additions and substitutions of the nucleic acid molecules of (a),
- (c) nucleic acid molecules that differ from the nucleic acid molecules of (a) or (b) in codon sequence due to the degeneracy of the genetic code, and
- (d) complements of (a), (b) or (c).
An isolated nucleic acid molecule selected from the group consisting of:
- (a) a unique fragment of the nucleotide sequence set forth as SEQ ID NO:1 or set forth as SEQ ID NO:3 between 12 and 115 nucleotides in length or more, and
- (b) complements of (a),
- wherein the unique fragments exclude nucleic acids having nucleotide sequences that are contained within SEQ ID NO:1 or SEQ ID NO:3, and that are known as of the filing date of this application.
An isolated nucleic acid molecule selected from the group consisting of:
- (a) nucleic acid molecules which hybridize under stringent conditions to a nucleic acid molecule having a nucleotide sequence selected from the group consisting of SEQ ID NOs:5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, or 29,
- (b) deletions, additions and substitutions of the nucleic acid molecules of (a),
- (c) nucleic acid molecules that differ from the nucleic acid molecules of (a) or (b) in codon sequence due to the degeneracy of the genetic code, and
- (d) complements of (a), (b) or (c).
A transgenic non-human animal which has reduced expression of a DOS nucleic acid molecule or of a Mutant DOS nucleic acid molecule.
15-17. (canceled)
A method for diagnosing a disorder characterized by aberrant expression of a DOS molecule, comprising:
- detecting in a first biological sample obtained from a subject, expression of a DOS molecule or a Mutant DOS molecule,
- wherein decreased expression of a DOS molecule or the increased expression of a Mutant DOS molecule compared to a control sample indicates that the subject has a disorder characterized by aberrant expression of a DOS molecule.
24-25. (canceled)
27-43. (canceled)
A kit for diagnosing a disorder associated with aberrant expression of a DOS molecule, comprising:
- one or more nucleic acid molecules that hybridize to a DOS nucleic acid molecule or to a Mutant DOS nucleic acid molecule under stringent conditions,
- one or more control agents, and
- instructions for the use of the nucleic acid molecules, and agents in the diagnosis of a disorder associated with aberrant expression of a DOS molecule.
45-46. (canceled)
A kit for diagnosing a DOS tumor in a subject comprising:
- one or more binding polypeptides that selectively bind to a DOS protein or a Mutant DOS protein,
- one or more control agents, and
- instructions for the use of the binding polypeptides, and agents in the diagnosis of a disorder associated with aberrant expression of a DOS molecule.
48-50. (canceled)
A method for treating a subject with a disorder characterized by aberrant expression of a DOS molecule, comprising
- administering to the subject an effective amount of a DOS nucleic acid molecule to treat the disorder.
A method for treating a subject with a disorder characterized by aberrant expression of a DOS molecule, comprising
- administering to the subject an effective amount of an anti-sense molecule to a Mutant DOS nucleic acid molecule to treat the disorder.
(canceled)
A method for treating a subject with a disorder characterized by aberrant expression of a DOS molecule, comprising
- administering to the subject an effective amount of a DOS protein to treat the disorder.
A method for treating a subject with a disorder characterized by aberrant expression of a DOS molecule, comprising
- administering to the subject an effective amount of a binding polypeptide to a Mutant DOS protein to treat the disorder.
56-58. (canceled)
A method for producing a DOS protein comprising
- providing a DOS nucleic acid molecule operably linked to a promoter, wherein the DOS nucleic acid molecule encodes the DOS protein or a fragment thereof,
- expressing the DOS nucleic acid molecule in an expression system, and
- isolating the DOS protein or a fragment thereof from the expression system.
(canceled)
A method for producing a Mutant DOS protein comprising
- providing a Mutant DOS nucleic acid molecule operably linked to a promoter, wherein the Mutant DOS nucleic acid molecule encodes the Mutant DOS protein or a fragment thereof,
- expressing the Mutant DOS nucleic acid molecule in an expression system, and
- isolating the Mutant DOS protein or a fragment thereof from the expression system.
