Human Papillomavirus 16-Transgenic Mice as a Model to Study Cancer-Associated Cachexia.

ABSTRACT: Cancer cachexia is a multifactorial syndrome characterized by general inflammation, weight loss and muscle wasting, partly mediated by ubiquitin ligases such as atrogin-1, encoded by Fbxo32. Cancers induced by high-risk human papillomavirus (HPV) include anogenital cancers and some head-and-neck cancers and are often associated with cachexia. The aim of this study was to assess the presence of cancer cachexia in HPV16-transgenic mice with or without exposure to the chemical carcinogen 7,12-dimethylbenz(a)anthracene (DMBA). Male mice expressing the HPV16 early region under the control of the cytokeratin 14 gene promoter (K14-HPV16; HPV+) and matched wild-type mice (HPV-) received DMBA (or vehicle) topically over 17 weeks of the experiment. Food intake and body weight were assessed weekly. T
