ABSTRACT
Objective To explore the invasion effect of CXCR3 overexpression on T lymphoblastic leukemia (Jurkat cells) with chemokine receptors. Methods Mouse CXCR3 was amplified by RT-PCR and overexpressing CXCR3 lentivirus carrying GFP&Puromycin (puro) was constructed. CXCR3 expression on infected Jurkat cells surface was detected by FCM. Constructed cells were seeded in Transwell invasion model to study whether CXCR3 overexpression would increase the invasion or not. Results GFP expression on Jurkat cells was less than 10% after 96 h lentivirus infection. CXCR3 expression was 90% higher than vector group , and GFP expression reached 90% after screening. Therefore, Jurkat cells with stable overexpression of CXCR3 were successfully constructed. Invasion rate of Jurkat CXCR3 cells was [(12.71 ± 1.03)%], which was significant higher than that of vector control group [(6.82 ± 0.49)%], (P < 0.0001). Conclusions CXCR3 expression on leukemia cells is closely associated with leukemia invasion. The increase of CXCR3 expression can enhance the invasion of leukemia cells, and may be one of the mechanisms of T lymphoblastic leukemia invasion.
