Objective:The aim of the study was to observe the expressions of genes related to genome stability and DNA repair in the members of nasopharyngeal carcinoma(NPC) clustering families.Methods:In the Zhongshan City where there is highly incidence rate of NPC,we chose the members of the NPC clustering families as objects,and the patients of nasopharyngitis and NPC as the control group.We isolated the RNA from the nasopharyngeal tissue,and synthesized its cRNA,the genome stability and DNA repair genes chip technique,chemiluminescent detection and real-time fluorescence quantitative technique were used to examine the genome stability and DNA repair genes in the nasopharyngeal tissue.Results:More genome stability and DNA repair genes were up-regulated in the members of the NPC clustering families than the NPC patients,and the range of up-regulated was high,with the over up-regulated 100 times genes including TEP1,MSH4,PMS2L1.Fewer genome stability and DNA repair genes were down-regulated in the members of the NPC clustering families than the NPC patients,the ubiquitin genes almost were down-regulated,the results also could be confirmed by real-time fluorescence quantitative PCR.Conclusion:There are specially expression character of genome stability and DNA repair genes in the members of NPC clustering families.
