Application Number:	14/199,292
Patent Claims:	1. A method for detecting the presence of uroplakin 1B (UPK1B) and at least one marker selected from androgen receptor (AR), corticotrophin releasing hormone (CRH), insulin-like growth factor 2 (IGF2), keratin 20 (KRT20) and annexin 10 (ANXA10) in a urine sample from a human subject comprising (a) obtaining the urine sample from the human subject; (b) isolating nucleic acid from the sample; and (c) detecting UPK1B and at least one additional marker selected from AR, CRH, IGF2, KRT20, and ANXA10 by performing a polymerase chain reaction (PCR) comprising contacting the nucleic acid from the sample with a set of two to six bladder cancer marker primer pairs. 2. The method of claim 1, wherein the set of bladder cancer markers comprises: a) UPK1B, AR, CRH, IGF2, KRT20, and ANXA10; b) UPK1B AR, CRH, IGF2, and KRT20; c) UPK1B, CRH, IGF2, and ANXA10; or d) UPK1B, CRH, IGF2, and KRT20. 3. The method of claim 1, further comprising detecting an endogenous control and measuring the level of UPK1B and the at least one additional marker in the sample relative to the endogenous control range or value. 4. The method of claim 3, wherein the endogenous control is selected from ABL, GUSB, GAPDH, TUBB, and UPK1a. 5. The method of claim 1, further comprising detecting an exogenous control and measuring the level of UPK1B and the at least one additional marker in the sample relative to the exogenous control range or value. 6. The method of claim 5, wherein the exogenous control is an RNA. 7. The method of claim 1, wherein detecting the presence of uroplakin 1B (UPK1B) and the at least one additional marker comprises RT-PCR. 8. The method of claim 7, wherein the method further comprises detecting an endogenous control and comparing a Ct value or a .DELTA.Ct value for each of UPK1B and at least one additional marker to a threshold Ct value or .DELTA.Ct value, wherein .DELTA.Ct is the Ct value for the endogenous control minus the Ct value for the markers from the sample. 9. The method of claim 7, wherein the RT-PCR reaction takes less than 2 hours from an initial denaturation step through a final extension step. 10. The method of claim 1, wherein the method further comprises hybridizing an oligonucleotide probe for detecting UPK1B comprising at least 8 contiguous nucleotides of SEQ ID NO: 53 to nucleic acids amplified from the PCR reaction. 11. The method of claim 1, wherein each bladder cancer marker primer pair produces an amplicon that is 50 to 500 nucleotides long. 12. The method of claim 1, wherein at least one bladder cancer marker primer pair spans an intron in the genomic sequence of a marker detected by the primer pair. 13. The method of claim 1, wherein the primer pair for detecting uroplakin 1B (UPK1B) comprises a first primer comprising at least 8 nucleotides of SEQ ID NO: 51 and a second primer comprising at least 8 nucleotides of SEQ ID NO: 52. 14. The method of claim 1, wherein the method further comprises forming a set of two to six bladder cancer marker amplicons, wherein the set of bladder cancer marker amplicons comprises a UPK1B amplicon, and contacting the bladder cancer marker amplicons with a set of bladder cancer marker probes, wherein the set of bladder cancer marker probes comprises a probe for UPK1B comprising at least 8 contiguous nucleotides of SEQ ID NO: 53. 15. The method of claim 14, wherein the set of bladder cancer marker amplicons comprises an amplicon selected from an AR amplicon, a CRH amplicon, a IGF2amplicon, a KRT20 amplicon, and a ANXA10 amplicon, and wherein the set of bladder cancer marker probes comprises a probe for detecting one or more of the AR, CRH, IGF2, KRT20, and ANXA10 amplicons. 16. The method of claim 15, wherein the set of bladder cancer marker amplicons comprises an AR amplicon, and the set of bladder cancer marker probes comprises a probe for detecting AR comprising the sequence of SEQ ID NO: 56. 17. The method of claim 14, wherein the probe for detecting uroplakin 1B (UPK1B) comprises at least 8 contiguous nucleotides of SEQ ID NO: 53, wherein the probe is less than 30 nucleotides long. 18. The method of claim 14, wherein each bladder cancer marker probe comprises a dye, and wherein each dye is detectably different from the dyes of up to three other probes. 19. The method of claim 18, wherein each probe comprises a quencher molecule. 20. The method of claim 14, wherein the probe for UPK1B comprises the sequence of SEQ ID NO: 53. 21. The method of claim 14, wherein at least one probe comprises a fluorescent dye. 22. The method of claim 1, wherein the set of bladder cancer markers are detected in a single multiplex reaction. 23. The method of claim 1, wherein the urine sample comprises urothelial cells. 24. The method of claim 1, wherein the subject has at least one symptom of bladder cancer. 25. The method of claim 24, wherein the at least one symptom is selected from abdominal pain, blood in the urine, painful urination, frequent urination, urinary urgency, and incontinence. 26. The method of claim 1, wherein the subject has a history of bladder cancer. 27. The method of claim 26, wherein the subject is being monitored for recurrence of bladder cancer. 28. The method of claim 26, wherein the subject has been treated with Bacillus Calmette-Guerin (BCG) in the past three months. 29. The method of claim 1, wherein the subject has low grade bladder cancer.
