Abstract

An oncogene designated PAX8-PPARgamma1 contains a PAX8 coding region fused to PPARgamma coding region. Molecular characterization of PAX8-PPARgamma1 molecules provides nucleotide and amino acid sequences useful for detection and treatment of certain tumors, particularly thyroid follicular carcinomas.

Claims

A method of identifying the presence of a PAX8-PPARγ1 or a PPARγ1-PAX8 molecule in a sample, the method comprising:
detecting with a nucleic acid probe for a PAX8-PPARγ1 or a PPARγ1-PAX8 nucleic acid molecule the presence of a PAX8-PPARγ1 or a PPARγ1-PAX8 molecule in the sample.
The method of claim 1 , wherein the detecting comprises:
contacting the sample with at least two nucleic acid amplification primers, wherein a first nucleic acid amplification primer is capable of hybridizing to a PAX8 nucleic acid molecule and a second nucleic acid amplification primer is capable of hybridizing to a PPARγ1 nucleic acid molecule,
amplifying a primed nucleic acid molecule which hybridizes to the first and the second nucleic acid amplification primers, and
detecting the presence of an amplified nucleic acid molecule in the sample.
The method of claim 1 , wherein the detecting comprises:
contacting the sample with at least two nucleic acid probes, wherein a first nucleic acid probe is capable of hybridizing to a PAX8 nucleic acid molecule and a second nucleic acid probe is capable of hybridizing to a PPARγ1 nucleic acid molecule, and
detecting the presence of a nucleic acid molecule in the sample which hybridizes to both the first and the second nucleic acid probes.
The method of claim 1 , wherein the detecting comprises:
contacting the sample with a nucleic acid probe which is capable of hybridizing to a PAX8-PPARγ1 nucleic acid fusion juncture, and
detecting the presence of a nucleic acid molecule in the sample which hybridizes to the nucleic acid probe.
The method of claim 4 , wherein the PAX8-PPARγ1 nucleic acid fusion juncture comprises a sequence selected from the group consisting of SEQ ID NO:7, SEQ ID NO:9 and SEQ ID NO:11.
The method of claim 1 , wherein the detecting comprises amplifying the PAX8-PPARγ1 or PPARγ1-PAX8 nucleic acid.
The method of claim 1 , wherein the sample is a thyroid tissue sample.
The method of claim 7 , wherein the thyroid tissue sample is from a patient suspected of having a thyroid cancer.
