Background

Carcinoma of cervix is the major malignancy of women. For cervical cancer diagnostics, there are about 55-million Pap smear tests performed every year in the United States. Pap smear screening for cervical cancer can result in 20% to 40% of false-negative results that lead to sometimes painful biopsies and put women at risk for pregnancy complications such as preterm labor and low-birth weight infants. Therefore there is a great need for a more accurate test of developmental stages of cervical cancers.


Technology Description

Src is a key molecule in oncogenesis and plays a major role in early development and progression of cervical and other types of cancer such as breast, colon, pancreatic, and lung. The novel biosensor developed by UCSD researchers combines FRET technology with genetically encoded biosensors which allows the monitoring of the Src tyrosine kinase activity in live cells, with high temporal and spatial resolutions. This innovation can potentially improve the sensitivity and accuracy for diagnosis of cervical cancer with Pap test samples.


Applications

  • Diagnosis of cervical cancer with Pap test samples as well as other types of cancers
  • Combining with a standard Pap test to reduce the false-negative rate of cervical cancer diagnosis
  • Screening of new anticancer drug candidates against cervical cancer at different developmental stages

 

State Of Development

This technology has been further improved in the biosensor sensitivity, validated in cell culture and cervical biopsy samples.
