Signatures and determinants associated with cancer and methods of use thereof
The present invention provides methods of detecting cancer using biomarkers.
1. A method comprising:
a. assaying a biological sample from a subject to determine whether the subject has a tumor or is at risk of developing a tumor, by detecting expression of at least two determinants selected from a KRAS activation profile, wherein the determinants are ITGB2 and HEY1;
b. comparing the expression of said determinants to the expression of said determinants in a reference sample known to be free of tumor(s);
c. determining that the subject has a tumor or is at risk of developing a tumor if the determinants are upregulated in comparison to the reference sample; and
d. administering a treatment regimen, comprising administration of a prophylactic or a therapeutic compound that targets the KRAS oncogene or RAS pathway if the subject is determined to have a tumor.
2. The method of claim 1 , further comprising detecting the expression level of one or more markers selected from the group consisting of Determinants 1-26, 28-32, and 34-600 listed in Tables 1 and 2.
3. The method of claim 1 , further comprising measuring at least one standard parameter associated with a tumor.
4. The method of claim 1 , wherein the biological sample is taken from the subject prior to being treated for a tumor.
5. The method of claim 1 , wherein the biological sample is taken from the subject after being treated for a tumor.
