"Adolescence is a time of transition — a time when teenagers begin to decide who they are and what they want to become. As adults, we often look back at our lives and wish we had made smarter choices about our health, education and relationships. In my work with adolescents, I am focused on helping to highlight and define the range of choices they can make. The choices are theirs, and they are ones that should be made thoughtfully, deliberately and with a goal in mind. Seeing adolescents recognize the power they have in making their own choices and being in charge of their own lives is wonderful to witness. "

  • Rachel Katzenellenbogen, MD, is attending physician in adolescent medicine at Seattle Children’s Hospital and assistant professor of pediatrics at the University of Washington School of Medicine. Her clinical interests include adolescent gynecology and STD management as well as general preventive medicine.

    Katzenellenbogen conducts NIH-sponsored research on high-risk human papillomavirus infection, which is linked to cervical cancer and is the most common sexually transmitted infection.  For more information, please visit:

Research Description

Human papillomavirus (HPV) is the most common sexually transmitted infection, affecting more than 75 percent of the adult population. HPV is categorized as high-risk or low-risk, based on its association with cancer. Through dysregulation of normal cellular function, high-risk HPV blocks signals for DNA damage, programmed cell death, and cellular arrest, all as a part of its viral life cycle. I am studying the mechanism by which high-risk HPV activates telomerase, an enzyme found normally in stem cells and almost categorically activated in cancers, in order to understand how HPV drives cells to become malignant.
