title: Expressions of cell cycle associated factors geminin and cdt1 in patients with acute leukemia.
abstract: The purpose of this study was to detect the expression levels of geminin and cdt1 in peripheral blood and bone marrow from patients with newly diagnosed acute leukemia (AL), and further explore effects of them in the pathogenesis of AL. mRNA expression of geminin and cdt1 in peripheral blood and bone marrow of newly diagnosed AL patients was detected by SYBR Green real-time quantitative reverse transcription polymerase chain reaction(SYBR-RT-PCR). The results showed that mRNA expressions of both geminin and cdt1 in peripheral blood were positive in 10 out of 13 newly diagnosed ALL patients (76.92%) and in 9 out of 14 newly diagnosed AML patients (64.29%), while no positive expression of these 2 genes was detected in 10 normal controls; mRNA expression levels of geminin and cdt1 in bone marrow of newly diagnosed ALL and AML patients were 108.06 ± 67.34 and 52.37 ± 35.16, 62.66 ± 58.69 and 26.68 ± 22.29, respectively, which were higher than those in normal controls (11.81 ± 2.83 and 7.32 ± 5.77), there were significant differences (p < 0.01 and p < 0.05). mRNA expression of geminin was significantly positive related to mRNA expression of cdt1 in bone marrow of 34 newly diagnosed AL patients (r = 0.55, p < 0.01). It is concluded that mRNA expressions of geminin and cdt1 are enhanced and significantly positively related between them in bone marrow of AL patients. The over-expression of geminin and cdt1 mRNA may play an important role in pathogenesis of AL.
