Methods of diagnosis of ovarian cancer, compositions and methods of screening for modulators of ovarian cancer
View Patent ↗Described herein are genes whose expression are up-regulated or down-regulated in ovarian cancer. Related methods and compositions that can be used for diagnosis and treatment of ovarian cancer are disclosed. Also described herein are methods that can be used to identify modulators of ovarian cancer.
1. A method of detecting ovarian cancer in a patient, the method comprising:
(i) detecting a nucleic acid in a first sample from the patient, wherein the nucleic acid sequence is at least 95% identical to SEQ ID NO:1, and wherein the nucleic acid encodes a G protein.coupled receptor 49; and
(ii) comparing the expression level of the nucleic acid in the-first sample to the expression level in a normal sample;
wherein an increase in the level of the nucleic acid relative to the normal sample is indicative of ovarian cancer.
2. The method of claim 1 , wherein the first sample comprises isolated nucleic acids.
3. The method of claim 2 , wherein the nucleic acids are mRNA.
4. The method of claim 2 , wherein the method further comprises the step of amplifying nucleic acids before the step of detecting the nucleic acid.
5. The method of claim 1 , wherein the nucleic acid comprises SEQ ID NO:1.
6. The method of claim 1 , wherein the detecting step is carried out by using a nucleic acid probe that hybridizes under stringent conditions to a nucleic acid comprising SEQ ID NO:1.
7. The method of claim 6 , wherein the probe is immobilized on a solid surface.
8. The method of claim 1 , wherein the patient is suspected of having ovarian cancer.
9. The method of claim 1 , wherein the patient is suspected of having ovarian cancer.
10. An isolated nucleic acid molecule, wherein the nucleic acid molecule comprises a sequence at least 99% identical to SEQ ID NO:1.
11. The nucleic acid molecule of claim 10 , wherein the nucleic acid molecule is labeled.
12. An expression vector comprising the nucleic acid of claim 10 .
13. A host cell comprising the expression vector of claim 12 .
14. A method of monitoring ovarian cancer in a human patient, the method comprising:
(i) detecting a nucleic acid in a first sample from the patient, wherein the nucleic acid sequence is at least 95% identical to SEQ ID NO:1, and wherein the nucleic acid encodes a G protein-coupled receptor 49;
(ii) comparing the expression level of the nucleic acid in the first sample to the expression level in a normal sample.
15. The method of claim 14 , wherein the sample comprises blood from the patient.
16. The method of claim 14 , wherein the nucleic acid sequence comprises SEQ ID NO:1.
17. The method of claim 14 , wherein the detecting step is carried out by using a nucleic acid probe that hybridizes under stringent conditions to a sequence comprising SEQ ID NO:1.
18. The method of claim 17 , wherein the probe is immobilized on a solid surface.
