1. A method of upregulating a function of and/or the expression of a PTEN Tumor Suppressor gene polynucleotide in patient cells or tissues in vivo or in vitro comprising:
- contacting said cells or tissues with at least one single-stranded antisense oligonucleotide of 15 to 30 nucleotides in length that targets, is 100% complementary to and specifically hybridizes to a complementary region of a natural antisense polynucleotide of a Tumor Suppressor gene polynucleotide selected from the group consisting of nucleotides 1-189 of SEQ ID NO;
14 and nucleotides 1-467 of SEQ ID NO;
15;
thereby upregulating a function of and/or the expression of the Tumor Suppressor gene polynucleotide in patient cells or tissues in vivo or in vitro.

Abstract
The present invention relates to antisense oligonucleotides that modulate the expression of and/or function of Tumor Suppressor genes, in particular, by targeting natural antisense polynucleotides of Tumor Suppressor genes. The invention also relates to the identification of these antisense oligonucleotides and their use in treating diseases and disorders associated with the expression of Tumor Suppressor genes.

9. A method of upregulating a function of and/or the expression of a Tumor Suppressor gene in mammalian cells or tissues in vivo or in vitro comprising:
contacting said cells or tissues with at least one antisense oligonucleotide of about 20 to 30 nucleotides in length specifically hybridizing to a natural antisense strand of a PTEN Tumor Suppressor gene polynucleotide wherein said at least one single-stranded antisense oligonucleotide has at least 100% sequence complementarity to 20 to 30 nucleotides within at least one nucleic acid sequence set forth as SEQ ID NO;
14 and, upregulating the function and/or expression of the PTEN Tumor Suppressor gene in mammalian cells or tissues in vivo or in vitro and further wherein the target region includes nucleotides 1-189, 431-789 of SEQ ID NO;
14 and nucleotides 1-467 of SEQ ID NO;

10. A method of preventing or treating a disease associated with at least one Tumor Suppressor gene polynucleotide and/or at least one encoded product thereof, comprising:
administering to a patient a therapeutically effective dose of at least one antisense oligonucleotide of 15 to 30 nucleotides in length that is 100% complementary to and specifically hybridizes to a complementary region of a natural antisense sequence of said at least one Tumor Suppressor gene polynucleotide having nucleotides 1-189 of SEQ ID NO;
14 or nucleotides 1-467 of SEQ ID NO;
15 and upregulates expression of said at least one Tumor Suppressor gene polynucleotide;
thereby preventing or treating the disease associated with the at least one Tumor Suppressor gene polynucleotide and/or at least one encoded product thereof and further wherein the disease is selected from cancer.
