Methods and compositions for the detection of cervical disease
First Claim
1. A method for diagnosing high-grade cervical disease in a patient independent of the patient'"'"'s HPV infection status, said method comprising:
- a) obtaining a body sample from said patient;
b) contacting said sample with at least one antibody, wherein said antibody specifically binds to a nuclear biomarker protein that is selectively overexpressed in high-grade cervical disease, wherein said biomarker protein is selected from the group consisting of p14ARF, p21waf1, Topo2A, and Cyclin E; and
,c) detecting binding of said antibody to said nuclear biomarker protein to determine if said biomarker protein is overexpressed in said sample, and thereby diagnosing high-grade cervical disease in the patient.

Abstract
Methods and compositions for identifying high-grade cervical disease in a patient sample are provided. The methods of the invention comprise detecting overexpression of at least one biomarker in a body sample, wherein the biomarker is selectively overexpressed in high-grade cervical disease. In particular claims, the body sample is a cervical smear or monolayer of cervical cells. The biomarkers of the invention include genes and proteins that are involved in cell cycle regulation, signal transduction, and DNA replication and transcription. In particular claims, the biomarker is an S-phase gene. In some aspects of the invention, overexpression of a biomarker of interest is detected at the protein level using biomarker-specific antibodies or at the nucleic acid level using nucleic acid hybridization techniques. Kits for practicing the methods of the invention are further provided.
