Methods： The total RNA was extracted from NPC cell line CNE-2 and tissues with Trizol and then been transcribed reversely to cDNA, a method of real time fluorescence quantitative RT-PCR for detecting the expression of Survivin mRNA in NPC tissues had been established, in which chronic nasopharyn-gitis patients＇ nasopharynx tissues treated as control group. Results： The expression of Survivin mRNA all could be detected either in CNE-2 cells, NPC tissues or in chronic nasopharyngitis patients＇ nasopharynx tissues, and there was higher the expression level of Survivin mRNA in NPC tissues than which in chronic nasopharyngitis patients＇ nasopharynx tissues, the difference was significant （P 〈 0.01）. The expression of Survivin mRNA could be detected both in stage Ⅰ ＋ Ⅱ and stage Ⅲ ＋ Ⅳ NPC, and there was no significant difference in relative quantifications of gene expression between these two groups （P 〉 0.05）. There was no relationship between Survivin mRNA expression and age and sex of NPC patients （P 〉 0.05）. Conclusion： Real time fluorescence quantitative RT-PCR is a rapid, effective and high sensitive method for detecting the expression of Survivin mRNA in NPC tissues. The overexpression of Survivin mRNA may play some roles in pathogenesis of NPC.展开更多

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 quantita- tive 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, PMS2LI. 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.展开更多
