Abstract
Compositions and methods for cancer research, diagnosis, and treatment, including but not limited to, cancer markers are provided. In particular, SPINK1 and other markers for prostate cancer are provided.
Claims13
A method for identifying prostate cancer in a patient comprising:
- (a) providing a sample containing prostate cells from the patient;
- (b) detecting in the sample containing prostate cells overexpression of SPINK1 compared to normal expression of SPINK1;
- and
- (c) detecting in the sample containing prostate cells normal expression of ERG and/or ETV1,
- wherein detecting in the sample containing prostate cells mutually exclusive overexpression of SPINK1 compared to normal expression of ERG and/or ETV1 identifies prostate cancer in the patient.
