Im Rahmen dieser Arbeit wurden Gewebe von jeweils 15 kolorektalen MSI- und CSIPrimärtumoren, sowie 3 MSI- und 2 CSI-Tumorzelllinien mittels SNP-Arrayanalyse molekulargenetisch auf uniparentale Disomie (UPD) untersucht. Es konnte bestätigt werden, dass die uniparentale Disomie ein wichtiger Mechanismus zur Inaktivierung von Tumorsuppressorgenen zu sein scheint. Die Ergebnisse zeigen, dass nicht nur in MSI-Tumoren, sondern auch in CSI-Tumoren UPD nachgewiesen werden konnte, wobei der UPD-Anteil an identifizierten LOH-Regionen in MSI-Tumoren mit 94% gegenüber 41% in CSI-Tumoren deutlich höher lag. Interessanterweise wurde auch in 68% der korrespondierenden MSI- und in 27% der entsprechenden CSINormalgewebe UDP festgestellt, was daraufhin deute...
