Abstract: Objective To investigate correlation between the expression of TIG1 and the prognostic significance in acute leukemia (AL).Methods The TIG1 expression level of 75 AL and 20 normal control (NC) were measured by Real-Time Quantitative PCR(RT-QT-PCR).Results TIG1 gene expressed at a higher level in NC(0.0609±0.0281 ) than that in de novo AL(0.0057±0.0035)(U=-6.321,P=0.000).The expression of TIG1 in complete remission patients(AL-CR)(0.0409±0.0244)were lower than that in NC too(U=-2.582,P=0.01).The expression of TIG1 in AL-CR patients (83.3 ％) were higher than that in de novo AL (53.1％)(U=-6.366,P=0.000).In AL patients,the CR rate of high TIG1 level cases were higher than that in low level cases (x2=4.563,P=0.033).Conclusions Reduced expression of TIG1 may play an important role in the pathogenesis of AL.TIG1 can serve as a marker of poor prognosis in AL.
