Description

Researchers at Georgetown University have identified a novel panel of biomarkers that could be used in the diagnosis, prognosis and treatment of cervical cancer or cervical dysplasia. The present invention relates to such methods by using a combination of certain biomarkers such as hTERT, IGFBP-3, transferrin receptor, beta-catenin, Myc-HPV E6 interaction, HPV E7, and telomere length.

Applications

  • Biomarkers can be used to classify the grade of cervical lesion for diagnostic and prognostic purposes.
  • Use of gene-silencing to knock-down expression of the biomarkers
  • Use panel for the screening of therapeutic agents that target one or more of the biomarkers

Advantages

  • Noninvasive procedures
  • Suitable for large scale screening of patients
  • More accurate than conventional cytological screening
  • Possible to select the treatment most appropriate for that patient by predicting the final diagnostic group of a patient by classifying the grade of a cervical lesion.

Stage of Development

In-vitro studies completed.
