Identification of Tumor-Associated Markers for Diagnosis and Therapy

Abstract

The present technology relates to genetic products the expression of which is associated with cancer diseases. The present technology also relates to the therapy and diagnosis of diseases in which the genetic products are expressed or aberrantly expressed, in particular cancer diseases.

         49 . A method of diagnosing or monitoring a lung cancer or a colon cancer, wherein the method comprises the steps of:
 detecting the presence of or determining the quantity of a tumor-associated nucleic acid in a biological sample comprising lung or colon tissue isolated from a mammal having or suspected of having lung or colon cancer, and   diagnosing or monitoring lung or colon cancer based on the presence or quantity of the tumor-associated nucleic acid in the biological sample, wherein
 the tumor-associated nucleic acid is selected from the group consisting of (a) a nucleic acid that comprises a nucleic acid sequence consisting essentially of SEQ ID NO: 587, and (b) a nucleic acid that has at least 90% sequence identity with the nucleic acid of (a); 
 the detecting or determining comprises (i) contacting the biological sample with an agent that binds specifically to the tumor-associated nucleic acid, and (ii) detecting the formation of or determining the quantity of a complex between the agent and the tumor-associated nucleic acid wherein said agent is an oligonucleotide or polynucleotide that hybridizes specifically to the tumor-associated nucleic acid or to the complementary nucleic acid sequence, and has a nucleic acid sequence comprising SEQ ID NO: 589 or 590; and 
 the lung or colon cancer is characterized by expression of or abnormal expression of a tumor-associated antigen encoded by the tumor-associated nucleic acid. 
   
     
     
         50 . The method of  claim 49 , wherein the monitoring of the lung or the colon cancer comprises determining regression, course or onset of the lung or colon cancer in the mammal. 
     
     
         51 . The method of  claim 49 , wherein the method comprises a detection of the presence of or a determination of the quantity of the tumor-associated nucleic acid in a first sample at a first point in time and in a further sample at a second point in time and a comparison of the presence of or quantity of the tumor-associated nucleic acid in the two samples. 
     
     
         52 . The method of  claim 49 , wherein the agent is labeled in a detectable manner. 
     
     
         53 . The method of  claim 49 , wherein the lung or colon tissue is from a tissue biopsy. 
     
     
         54 . The method of  claim 49 , wherein the tumor-associated antigen comprises an amino acid sequence consisting essentially of SEQ ID NO: 588. 
     
     
         55 . A method of diagnosing or monitoring lung or colon cancer, wherein the method comprises the steps of:
 detecting or determining the quantity of a tumor-associated nucleic acid in a biological sample comprising lung or colon tissue isolated from a mammal having or suspected of having lung or colon cancer, and   diagnosing or monitoring lung or colon cancer based on the presence or quantity of the tumor-associated nucleic acid in the biological sample, wherein
 the tumor-associated nucleic acid is selected from the group consisting of (a) a nucleic acid that comprises a nucleic acid sequence consisting essentially of SEQ ID NO: 587, and (b) a nucleic acid that has at least 90% sequence identity with the nucleic acid of (a); 
 the detecting or determining comprises (i) contacting the biological sample with an agent that binds specifically to the tumor-associated nucleic acid, and (ii) detecting the formation of or determining the quantity of a complex between the agent and the tumor-associated nucleic acid via real-time reverse-transcription polymerase chain reaction (RT-PCR); 
 the lung or colon cancer is characterized by expression or abnormal expression of a tumor-associated antigen encoded by the tumor-associated nucleic acid; and 
 the agent is an oligonucleotide or polynucleotide that hybridizes specifically to the tumor-associated nucleic acid or to the complementary nucleic acid sequence, and has a nucleic acid sequence comprising SEQ ID NO: 589 or 590. 
   
     
     
         56 . The method of  claim 55 , wherein the monitoring of the lung or colon cancer comprises determining regression, course or onset of the lung or colon cancer in the mammal. 
     
     
         57 . The method of  claim 55 , wherein the method comprises a detection of the presence of or determination of the quantity of the tumor-associated nucleic acid in a first sample at a first point in time and in a further sample at a second point in time and a comparison of the presence of or quantity of the tumor-associated nucleic acid in the two samples. 
     
     
         58 . The method of  claim 55 , wherein the agent is labeled in a detectable manner. 
     
     
         59 . The method of  claim 55 , wherein the lung or colon tissue is from a tissue biopsy. 
     
     
         60 . The method of  claim 55 , wherein the tumor-associated antigen comprises an amino acid sequence consisting essentially of SEQ ID NO: 588. 
     
     
         61 . The method of  claim 55 , wherein the agent is an oligonucleotide or polynucleotide that hybridizes specifically to the tumor-associated nucleic acid and has a nucleic acid sequence comprising SEQ ID NO: 589. 
     
     
         62 . The method of  claim 55 , wherein the agent is an oligonucleotide or polynucleotide that hybridizes specifically to the tumor-associated nucleic acid and has a nucleic acid sequence comprising SEQ ID NO: 590. 
     
     
         63 . The method of  claim 49 , wherein the lung cancer is an adenocarcinoma or a squamous cell carcinoma. 
     
     
         64 . The method of  claim 55 , wherein the lung cancer is an adenocarcinoma or a squamous cell carcinoma.
