Abstract
The invention relates to methods and biomarkers (e.g., epigenetic biomarkers) for detection of bladder cancer in biological samples (e.g., tissue samples, urine samples, urine sediments). In some embodiments, methods and biomarkers of the present invention find use in discriminating between bladder cancer, prostate cancer and renal epithelial tumors.
Claims21
A method for predicting a predisposition to bladder cancer in a subject, diagnosing a bladder cancer in a subject, predicting the likelihood of recurrence of bladder cancer in a subject, providing a prognosis for a subject with bladder cancer, or selecting a subject with bladder cancer for treatment with a particular therapy, comprising:
- a) contacting a biological sample from a subject with a reagent for detecting the methylation status of a nucleic acid segment corresponding to the VIM locus;
- and
- b) detecting the methylation status of said nucleic acid segment corresponding to the VIM locus using an in vitro assay,
- wherein an increased degree of methylation of said nucleic acid segment corresponding to the VIM locus in said sample relative to a reference methylation status provides an indication selected from the group consisting of an indication of a predisposition of the subject to bladder cancer, an indication that the subject has bladder cancer, an indication of the likelihood of recurrence of bladder cancer in the subject, an indication of survival of the subject, and an indication that the subject is a candidate for treatment with a particular therapy.
A methylation specific nucleic acid detection reagent corresponding to a VIM locus nucleic acid sequence.
A set of methylation specific nucleic acid detection reagents specific for potentially methylated regions of one or more specific loci being suitable to diagnose or predict bladder cancer, wherein said loci comprise one or more of the VIM locus, GDF15 locus, HSPA2 locus, and TMEFF2 locus.
A kit for detecting the presence of a bladder neoplasm in a mammal, said kit comprising reagents useful, sufficient, or necessary for detecting and/or characterizing level, presence, or frequency of methylation of a VIM locus.
