A Review of Current Animal Models for the Study of Cervical Dysplasia and Cervical Carcinoma

AbstractCancer research has long relied on animal models for the study of disease mechanisms and new therapeutics. Future cancer treatments are likely to rely heavily on patient-derived xenograft models to develop novel treatments and tailor regimens to individual patient needs. However, specific models for cervical cancer and cervical dysplasia are limited. Only 3 models have been described in the published literature. A transgenic model for cervical cancer has allowed for the study of the differential contributions of the human papillomavirus 16 proteins E6 and E7 during oncogenesis. This model has also shown dysplasia development, although this has received little attention. A patient-derived tumor xenograft model where cervical cancer tissue is transplanted to the subcutaneous and orthotopic sites has been described. Here we review the reported transgenic and xenograft models, their strengths and limitations, and highlight the potential for the development of improved models to study cervical neoplasia.
