CIP2A as a biomarker in detection of cervical cancer

摘要

The present invention provides methods and compositions for detecting cervical cancer in a human. The present invention provides CIP2A as a biomarker detectable in a biological sample from cervix of an individual, an increased expression of same is an indication of cervical cancer in the individual. CIP2A mRNA or protein can both serve as reliable biomarkers. In one embodiment, the present invention provides a combined use of CIP2A with at least one additional biomarker selected from the group consisting of Ki67, TOP2A, MCM2, MCM5, p14^ARF and p16^INK4a, to better serve as a detection means for cervical cancer. The present invention provides a reliable and accurate assay methods and compositions which may be used for detecting cervical cancer in an individual with a high sensitivity and specificity. The present assay provides a novel use of CIP2A as a tool for early detection of cervical cancer in humans.
