Mechanisms of ERα and PR in HPV-associated cervical cancer

Human papillomaviruses (HPVs) cause various human cancers including those in the uterine cervix. The tumorigenic potential of HPV mainly stems from E6 and E7 viral oncoprotein, which inactivate p53 and pRb, respectively. Evidence indicates that, while HPV is necessary, it is not sufficient for cervical cancer. Studies using the HPV transgenic mice expressing E6 and E7 have demonstrated that estrogen and estrogen receptor α (ERα) are required for the development of cervical cancer. Dr. Sanghyuk Chung’s lab also demonstrated that progesterone and progesterone receptor (PR) inhibit cervical cancer. ERα and PR are transcription factors that belong to the nuclear receptor superfamily, which has been successfully targeted for various diseases including cancers. The lab’s primary interest is to understand molecular mechanisms by which ERα and PR exert opposing roles in cervical cancer using the HPV transgenic mouse model and the lab’s novel orthotopic xenograft mouse model. Chung anticipates that the studies will not only shed new light on pathogenesis of HPV-associated cervical cancer but also identify therapeutic targets for the cancer.
