Persistent human papillomavirus (HPV) infection can ultimately lead to cervical cancer. Our research explores the molecular and cellular changes that accompany HPV-mediated transformation and in vitroprogression of human epithelial cells, with an emphasis on HPV-induced alterations in signal transduction pathways associated with cell proliferation (epidermal growth factor pathway) as well as inhibition of cell growth (transforming growth factor-beta pathway).
In particular, gene expression profiling techniques (microarrays) are used to define molecular signatures associated with early and late stages of HPV-mediated transformation and alterations in growth factor responses. These studies have led to the finding that overexpression of the homeodomain transcription factor Six1 in HPV16-immortalized human keratinocytes promotes differentiation resistance, epithelial-mesenchymal transition (EMT), and malignant conversion.
We also conduct studies in women to explore environmental and genetic determinants of HPV persistence with the goal of identifying “biomarkers” that will predict risk of a cervical premalignant and malignant disease. Studies also are aimed at identifying a biological basis for the increased risk of cervical cancer in African American women compared to European American women. We recently discovered that high risk HPV persists longer in African American women than European American women of college age. Our research is supported by the National Institute for Minority Health and Health Disparities (5P20MD001770).
