Pathway Analysis using Gene-expression Profiles of HPV-positive and HPV-negative Oropharyngeal Cancer Patients in a Hispanic Population: Methodological Procedures

摘要

ObjectiveThe incidence of oral cavity and pharyngeal cancer in Puerto Rican men is higher than it is in the men of any other ethnic/racial group in the United States of America (US). The information regarding the effect of the human papilloma virus (HPV) in the gene-expression profile among patients with this cancer is limited in Hispanic community. We aim to describe the methodology for future studies to identify the molecular networks for determining overrepresented signaling and metabolic canonical pathways, based on the differential gene-expression profiles of HPV+ and HPV− samples from patients with oropharyngeal squamous cell carcinoma in Puerto Rico.
