Objective:
To investigate the expression and function of chemokine receptor CXCR2 and CXCR7 in the rat with acute leukemia.
Methods:
Flow cytometry and RT-PCR were used to detect the CXCR2, CXCR7 expression on the bone marrow cell surface of the acute leukemia group and the control group.
Results:
The bone marrow cell surface CXCR2, CXCR7 relative fluorescence intensity of the observation group was significantly higher than the control group (P<0.05). The CXCR7 expression of the extramedullary infiltration group was significantly higher than non-extramedullary infiltration group (P<0.05). The CXCR2, CXCR7mRNA median expression level of the observation group was higher than the control group. The CXCR2 expression and CXCR7 expression of the observation group was positively correlated, and the correlation coefficient was 0.782 (P<0.01).
Conclusions:
The chemokine receptor CXCR2 and CXCR7 are highly expressed in acute leukemia, which may be associated with the occurrence of leukemia.
