Research on SV 40 Exposure and the Development of Cancer - September 10, 2003

چکیده
Our Branch conducts population-based epidemiology research to clarify the relationship of infectious agents, especially viruses, to human cancer and other conditions. Viruses may cause or increase the risk of cancer through several mechanisms. These include allowing uncontrolled cell division, blocking DNA repair, and altering the immune system. While some viruses have been known to be related to cancer for many years, new infectious carcinogenic agents continue to be found. The Branch utilizes the principles of both infectious and chronic disease epidemiology, supported by collaborative statistical modeling and laboratory investigations.

متن کاملAre there Relationships between the VDR-FokI Polymorphism and Vitamin D and the Insulin Resistance in Non-melanoma Skin Cancer (NMSC) Patients? A Protocol for Case-control Studies
Background and Objectives: Evidence indicate relationships between the sunlight exposure, vitamin D status and non-melanoma skin cancer (NMSC) risk. Vitamin D receptor (VDR) polymorphisms have been linked to metabolic changes in insulin resistance and various cancers. The purpose of this study is to investigate relationships between the sunlight exposure and the NMSC risk. Furthermore, relation...
