%0 Book %T Gene mutations and losses of heterozygosity of TP53 and PTEN in colorectal cancer %A Salem, Tareq %D 2014 %G English %F 805590951 %O submitted by Tareq Salem %O Rostock, Univ., Med. Fak., Diss., 2014 %X This study was conducted to find out if the patterns of PTEN gene molecular aberration in colorectal carcinoma are consistent with the classic molecular features ascribed to a tumour suppressor gene. PTEN gene mutations and LOH were assayed in a series of 18 colorectal carcinomas. Three PTEN gene mutations were found in 1 tumour, complete loss of one allele(LOH)in 2 tumours and allelic imbalance (AI) in 6 tumours. LOH or AI did not target the 1 tumour with the PTEN gene mutations. The widely held belief of PTEN as a classical tumour suppressor gene is not supported by the findings from this study. %L 610 %9 theses %9 Text %9 Hochschulschrift %U http://rosdok.uni-rostock.de/resolve?urn=urn:nbn:de:gbv:28-diss2014-0174-3 %U http://rosdok.uni-rostock.de/resolve?urn=urn:nbn:de:gbv:28-diss2014-0174-3&pdf %U http://nbn-resolving.de/urn:nbn:de:gbv:28-diss2014-0174-3
