Biomarkers for the early detection of breast cancer
The present invention provides reagents and methods for breast cancer detection.
1. A polypeptide probe set comprising: a SF3A1 (SEQ ID NO: 2) isolated polypeptide (or antigenic fragment thereof) and a UBAP1 (SEQ ID NO: 47) isolated polypeptide (or antigenic fragment thereof) and one or more additional isolated polypeptides selected from the group consisting of ATP6AP1 (SEQ ID NO: 13), PDCD6IP (SEQ ID NO: 21), DBT (SEQ ID NO: 25), CSNK1E (SEQ ID NO: 9), FRS3 (SEQ ID NO: 3), HOXD1 (SEQ ID NO: 7), C15orf48 (SEQ ID NO: 35), MYOZ2 (SEQ ID NO: 33), BAT4 (SEQ ID NO: 5), BMX (SEQ ID NO: 45), RAB5A (SEQ ID NO: 23), GPR157 (SEQ ID NO: 43), ZMYM6 (SEQ ID NO: 41), SLC33A1 (SEQ ID NO: 11), TRIM32 (SEQ ID NO: 37), ALG10 (SEQ ID NO: 27), TFCP2 (SEQ ID NO: 49), SERPINH1 (SEQ ID NO: 51), SELL (SEQ ID NO: 55), ZNF510 (SEQ ID NO: 53), or antigenic fragments of any of the above; wherein each of the isolated polypeptides of the polypeptide probe set comprises a detectable tag; wherein the detectable tag is not a naturally occurring part of the isolated polypeptide; and wherein the probe set comprises no more than 100 different polypeptides.
2. The polypeptide probe set of claim 1 wherein the one or more additional isolated polypeptides comprise ATP6AP1 (SEQ ID NO: 13), or an antigenic fragment thereof.
3. The polypeptide probe set of claim 1 , wherein the probe set is present on a support.
4. The polypeptide probe set of claim 1 , wherein the probe set is present in solution.
5. The polypeptide probe set of claim 1 , wherein the probe set comprise no more than 50 different polypeptides.
6. The polypeptide probe set of claim 1 , wherein the probe set comprise no more than 25 different polypeptides.
