Gene products differentially expressed in cancerous cells and their methods of use II
The present invention provides polynucleotides, as well as polypeptides encoded thereby, that are differentially expressed in cancer cells. These polynucleotides are useful in a variety of diagnostic and therapeutic methods. The present invention further provides methods of reducing growth of cancer cells. These methods are useful for treating cancer.
1. A method for assessing the risk that a human patient has colon cancer comprising:
a) determining a level of a nucleic acid and a level of at least one molecular marker gene in a patient sample comprising human colon cells, said nucleic acid comprising the nucleotide sequence of SEQ ID NO: 23702;
b) comparing said level of the nucleic acid in (a) to a control level of the nucleic acid; and
c) comparing said level of the at least one molecular marker gene in (a) to a control level of the at least one molecular marker gene;
wherein at least a two-fold increase between the level of the nucleic acid in (a) and the control level of the nucleic acid, and a change in levels of expression between the level of the at least one molecular marker gene in (a) and the control level of the at least one molecular marker gene indicate that there is an increased risk that the patient has colon cancer.
2. The method of claim 1 wherein the at least a two-fold increase is at least a five-fold increase compared with the control level of the nucleic acid.
3. The method of claim 1 , wherein said determining step uses a polymerase chain reaction.
4. The method of claim 1 , wherein said determining step uses hybridization.
5. The method of claim 1 , wherein said patient sample is a sample of tissue suspected of having cancerous cells.
6. A method for assessing the risk that a human patient has breast cancer comprising:
a) determining a level of a nucleic acid and a level of at least one molecular marker gene in a patient sample comprising human breast cells, said nucleic acid comprising the nucleotide sequence of SEQ ID NO: 23702;
b) comparing said level of the nucleic acid in (a) to a control level of the nucleic acid; and
c) comparing said level of the at least one molecular marker gene in (a) to a control level of the at least one molecular marker gene;
wherein at least a two-fold increase between the level of the nucleic acid in (a) and the control level of the nucleic acid, and a change in levels of expression between the level of the at least one molecular marker gene in (a) and the control level of the at least one molecular marker gene indicate that there is an increased risk that the patient has breast cancer.
7. The method of claim 6 wherein the at least a two-fold increase is at least a five-fold increase compared with the control level of the nucleic acid.
8. The method of claim 6 , wherein said determining step uses a polymerase chain reaction.
9. The method of claim 6 , wherein said determining step uses hybridization.
10. The method of claim 6 , wherein said patient sample is a sample of tissue suspected of having cancerous cells.
