Prostate-specific gene for diagnosis, prognosis and management of prostate cancer
View Patent ↗Disclosed are nucleic acid and amino acid sequences encoded by a novel, prostate specific gene (UC41) and diagnostic techniques for the detection of human prostate cancer utilizing such nucleic acid and amino acid sequences. Genetic probes and methods useful in monitoring the progression and diagnosis of prostate cancer are described. Methods of treatment for prostate cancer utilizing antisense constructs or antibodies specific for UC41 gene products are also described.
1. A method for detecting metastatic prostate cancer cells in bone or lymph nodes, the method comprising:
a) obtaining a biological sample from an individual; and
b) detecting a prostate cancer marker in said sample,
wherein said prostate cancer marker is a nucleic acid comprising a sequence selected from the group consisting of SEQ ID NO:3 and SEQ ID NO:4.
2. The method of claim 1 , further comprising the steps of
a) amplifying nucleic acids from said sample to form nucleic acid amplification products;
b) contacting said nucleic acid amplification products with an oligonucleotide probe that will hybridize under stringent conditions with said prostate cancer marker;
c) detecting the nucleic acid amplification products which hybridize with said probe; and
d) measuring the amount of said nucleic acid amplification products that hybridize with said probe under stringent conditions,
wherein an increased amount of said prostate cancer marker in said sample, relative to the amount of said marker in normal tissue samples, is indicative of the presence of prostate cancer cells in the biological sample.
3. The method of claim 2 , wherein said oligonucleotide probe is capable of specifically hybridizing to an isolated nucleic acid comprising a sequence comprising SEQ ID NO:3, SEQ ID NO:4, or complements thereof.
4. The method of claim 1 , further comprising the steps of
a) providing primers that will selectively amplify said prostate cancer marker;
b) amplifying said nucleic acids with said primers to form nucleic acid amplification products;
c) detecting said nucleic acid amplification products; and
d) quantifying said nucleic acid amplification products,
wherein an increased amount of said prostate cancer marker in said sample, relative to the amount of said marker in normal tissue samples, is indicative of the prostate cancer cells.
5. The method of claim 4 , wherein said primers are selected to amplify a nucleic acid comprising a sequence comprising SEQ ID NO:3 and SEQ ID NO:4.
6. The method of claim 3 , further comprising determining the prognosis of prostate cancer patients by quantifying the nucleic acid amplification products binding to a probe specific for said prostate cancer marker.
7. The method of claim 3 , further comprising determining the diagnosis of human prostate cancer by quantifying the nucleic acid amplification products binding to a probe specific for said prostate cancer marker.
8. The method of claim 5 , further comprising determining the prognosis of prostate cancer patients by quantifying the nucleic acid amplification products.
9. The method of claim 5 , further comprising determining the diagnosis of human prostate cancer by quantifying the nucleic acid amplification products.
