Abstract:
Objective Estahlished the method to detect different transcripts of EVI1 gene expression with quantitative PCR and study the expression patterns of EVI1 gene in different leukemia groups to investigate the association between EVI1 gene expression and the incidence and prognosis of leukemia.Methods 60 cases acute myeloid leukemia (AML) and 9 cases normal control were detected in the study,37 cases were male and 32 cases were female,age 10-70 years,median age 42 years,M3 36 cases,M2 16 cases and M4 8 cases according to FAB classification criteria,control samples of nine cases were normal healthy people.Using the quantitative PCR (Taq Man probe) to detect the expression of different transcripts of EVI1 gene.The t test was used to detect the expression difference among different leukemia groups.Results ABL gene was used as internal reference,relative changes of EVI1 gene expression level were detected by EVI1/ABL.In all the control patients,EVI1 gene of different transcription of this expression were detected,expression level of EVI1 gene different transcription was significant with the difference (P ＜ 0.05),transcription 2 and 5 (the same primers) were the lowest,followed for transcription 1 and 6,expression of transcription 3 was the highest.The expression levels of transcripts 2 and 5,1,6,3 were nagative,0.005,0.050 and 0.512 respectively in healthy control samples.In addition,the EVI1 gene expression was negatively correlated with expression of the fusion gene AML-ETO and CBFB-MYH11 in AML.Conclusion The study established a stable,fast and accurate method to detect the expression of EVI1 gene.
