Centromere/kinetochore protein genes for cancer diagnosis, prognosis and treatment selection
View Patent ↗The invention described in the application relates to a panel of gene expression markers for patient with a tumor. The invention thus provides methods and compositions, e.g., kits, for evaluating gene expression levels of the markers and methods of using such gene expression levels to evaluate the likelihood of disease progression or response to chemotherapy or radiation therapy. Such information can be used in determining prognosis and treatment options for cancer patients.
1. A microarray for detecting expression of a gene panel for predicting likelihood of cancer progression in a patient, wherein the microarray consists of: CENP-A, HJURP, M1S18B, CENP-N, CENP-M, CENP-W, CENP-U, CENP-L, CENP-K, ZWINT, NDC80, NUF2, SPC24, and SPC25; and wherein the probes are immobilized by covalent bonds to a solid support, and each probe is 15 to 80 nucleotides in length.
2. A hybridization assay composition comprising the microarray of claim 1 and an RNA sample obtained sample from a tumor from a patient that has cancer; or a cDNA obtained from RNA from the tumor.
3. The hybridization assay of claim 2 , wherein the the tumor is from early stage breast cancer, an early stage non-small cell lung cancer, or an early stage ovarian cancer.
4. The hybridization assay of claim 3 , wherein the breast cancer is luminal A.
5. The hybridization assay of claim 3 , wherein the breast cancer is luminal B.
6. The hybridization assay of claim 3 , wherein the breast cancer is breast cancer is ER positive breast cancer.
7. A kit comprising amplification primers and probes, wherein the amplification primers and probes consist of amplification primers and probes that are specific for amplifying and detecting expression of a gene panel consisting of: CENP-A, HJURP, M1S18B, CENP-N, CENP-M, CENP-W, CENP-U, CENP-L, CENP-K, ZWINT, NDC80, NUF2, SPC24, and SPC25; and wherein the amplification primers or probes, or both the amplification primers and probes, are attached to a detectable label that is a radioisotope, a fluorophore, a chemiluminescent agent, or an enzyme.
