1Frequent mutations of the CA simple sequence repeat in intron 1 of EGFR in mismatch repair-deficient colorectal cancers显示文摘AIM:To investigate the polymorphic simple sequencerepeat in intron 1 of the epidermal growth factor receptorgene(EGFR)(CA-SSRⅠ),which is known to affect theefficiency of gene transcription as a putative target of themismatch repair(MMR)machinery in colorectal tumors.METHODS:The CA-SSRⅠgenotype was analyzed ina total of 86 primary colorectal tumors,selected upontheir microsatellite instability(MSI)status[42 with highfrequency MSI(MSI-H)and 44 microsatellite stable(MSS)]and their respective normal tissue.The effect of the CA-SSRⅠgenotype on the expression of the EGFR gene wasevaluated in 18 specimens using quantitative real-timereverse transcription PCR and immunohistochemistry.RESULTS:Mutations in CA-SSRⅠwere detected in 86%(36 of 42)of MSI-H colorectal tumors and 0%(0 of 44)ofMSS tumors,indicating the EGFR gene as a novel putativespecific target of the defective MMR system(P<0.001).Impaired expression of EGFR was detected in most ofthe colorectal tumors analyzed[6/12(50%)at the mRNAlevel and 15/18(83%)at the peptide level].However,noassociation was apparent between EGFR expression andCA-SSRⅠstatus in tumors or normal tissues.CONCLUSION:Our results suggest that CA-SSRⅠsequence does not contribute to the regulation of EGFRtranscription in colon,and should thus not be consideredas a promising predictive marker for response to EGFRinhibitors in patients with colorectal cancer.Marie-Pierre Buisine Agnès Wacrenier Christophe Mariette Emmanuelle Leteurtre Fabienne Escande Sana Aissi Amandine Ketele Annette Leclercq Nicole Porchet Thécla Lesuffleur 2008World Journal of Gastroenterology2008,14,7:3
