Four-jointed box (FJX1) in cancer diagnosis and treatment
The present invention relates to a new tumor suppressor, designated FJX1. Also described are diagnostic, prognostic and therapeutic uses of the FJX1 protein and the FJX1 gene, alone or in combination with traditional cancer therapies.
1. A method of diagnosing colorectal cancer comprising:
(a) obtaining a biological sample from a subject;
(b) assessing said biological sample for the level of a FJX1 nucleic acid;
(c) comparing the level of FJX1 nucleic acid observed in step (b) with a comparable sample from a normal subject; and
(d) diagnosing said subject with elevated FJX1 nucleic acid level in said biological sample, as compared to the nucleic acid level of FJX1 in said comparable sample from said normal subject, as having colorectal cancer.
2. The method of claim 1 , wherein said sample is a tissue sample.
3. The method of claim 2 , wherein said tissue sample is a biopsy.
4. The method of claim 1 , wherein said sample is a biological fluid sample.
5. The method of claim 4 , wherein said biological fluid sample is lymph, plasma, urine, feces or blood.
6. The method of claim 1 , wherein said nucleic acid is an mRNA.
