Expression Level and Clinical Significance of Gli1 in Patients with Myelodysplastic Syndrome / 中国实验血液学杂志

ABSTRACT

OBJECTIVE@#To study the expression level and clinical significance of Gli1 gene in patients with myelodysplastic syndrome(MDS).@*METHODS@#The positive rate of bone marrow CD34 cells was detected by flow cytometry in 53 patients with MDS.Magnetic beads were used to separate CD34 cells. The expression of Gli1 on CD34 cells was detected by RT-qPCR, 25 patients with iron deficiency anemia were selected as controls. The relationship of Gli1 expression with clinical characteristics were analyzed.@*RESULTS@#The expression of Gli1 in patients with MDS (0.73±1.26) was significantly higher than that in the control group (0.07±0.46) (P＜0.05). The expression of Gli1 significantly correlated with platelet count, chromosome grouping and IPSS risk stratification (P＜0.05). The median overall survival time of patients in high and low expression groups were 7 and 20 months respectively (P＜0.05). Multivariate analysis showed that Gli1 and chromosome grouping were 2 independent poor prognostic factors (P＜0.05).@*CONCLUSION@#The expression of Gli1 is high in MDS. Abnormal expression of Gli1 positively correlates with clinical characteristics and prognosis of patients.Gli1 may be involved in the occurrence and development of MDS.
