         2 . The compound of  claim 1  which is an antisense oligonucleotide.  
     
     
         3 . The compound of  claim 2  wherein the antisense oligonucleotide comprises at least one modified internucleoside linkage.  
     
     
         4 . The compound of  claim 3  wherein the modified internucleoside linkage is a phosphorothioate linkage.  
     
     
         5 . The compound of  claim 2  wherein the antisense oligonucleotide comprises at least one modified sugar moiety.  
     
     
         6 . The compound of  claim 5  wherein the modified sugar moiety is a 2′-O-methoxyethyl sugar moiety.  
     
     
         7 . The compound of  claim 2  wherein the antisense oligonucleotide comprises at least one modified nucleobase.  
     
     
         8 . The compound of  claim 7  wherein the modified nucleobase is a 5-methylcytosine.  
     
     
         9 . The compound of  claim 2  wherein the antisense oligonucleotide is a chimeric oligonucleotide.  
     
     
         10 . A compound 8 to 80 nucleobases in length which specifically hybridizes with at least an 8-nucleobase portion of a preferred target region on a nucleic acid molecule encoding PTPN12.  
     
     
         11 . A composition comprising the compound of  claim 1  and a pharmaceutically acceptable carrier or diluent.  
     
     
         12 . The composition of  claim 11  further comprising a colloidal dispersion system.  
     
     
         13 . The composition of  claim 11  wherein the compound is an antisense oligonucleotide.  
     
     
         14 . A method of inhibiting the expression of PTPN12 in cells or tissues comprising contacting said cells or tissues with the compound of  claim 1  so that expression of PTPN12 is inhibited.  
     
     
         15 . A method of treating an animal having a disease or condition associated with PTPN12 comprising administering to said animal a therapeutically or prophylactically effective amount of the compound of  claim 1  so that expression of PTPN12 is inhibited.  
     
     
         16 . The method of  claim 15  wherein the disease or condition arises from aberrant apoptosis.  
     
     
         17 . The method of  claim 15  wherein the disease or condition is a hyperproliferative disorder.  
     
     
         18 . The method of  claim 17  wherein the hyperproliferative disorder is cancer.  
     
     
         19 . The method of  claim 18  wherein the cancer is colon cancer.  
     
     
         20 . The method of  claim 15  wherein the disease or condition is a metabolic disorder.
