Although microsatellite instability (MSI) testing is a useful tool for molecular screening of hereditary nonpolyposis colorectal cancer (HNPCC) carcinomas, conflicting results have been obtained in colorectal adenomas. This might result from different techniques of tissue sampling and MSI analysis. Alternatively, some HNPCC-associated adenomas may follow a(More)
Hereditary non-polyposis colorectal cancer (HNPCC) accounts for approximately 2 to 4% of the total colorectal cancer burden. For economic reasons a diagnostic "stepladder" is recommended. After evaluation of the family history, diagnostic microsatellite instability (MSI) analysis has found its place as a valuable screening tool for HNPCC.(More)
The incidence of human papillomavirus (HPV) associated oropharyngeal squamous cell cancer (OSCC) is on the rise. With the HPV-positive uterine cervix as a reservoir, HPV-positive OSCC is discussed as a sexually transmitted disease. Mechanisms of HPV transmission to the oral cavity are poorly understood. To gain more insight into HPV-transmission routes,(More)
Thioredoxins (Trx) are ubiquitous dicysteine proteins capable of modulating enzymes and other cellular targets through specific disulfide-dithiol redox changes. They are unique in that a large number of very diverse metabolic systems are addressed and redox-regulated in bacteria, animal, and plant cells, but the finite number of thioredoxin interaction(More)
