Abstract  To construct the human GPR183 over-expressing lentiviral vector and investigate the effect of GPR183 on apoptosis of human T-ALL cell line Cutll1 cells, the human GPR183 cDNA sequence was amplified by PCR and linked to the lentivirus vector pEZ-Lv201 and the GPR183-overexpressing lentivirus plasmid was constructed then lentivirus was packaged by using 293T cells. The Cutll1 cells were infected with lentivirus and the GPR183 expression level was detected by q-PCR and Western blot. The CCK-8, PI and Annexin V staining were used to study the growth, cell cycle and apoptosis of the Cutll1 cell with (Cutll1-GPR183) or without (negative control) GPR183 overexpression. The plasmid confirmation PCR and sequencing data indicate the human GPR183- overexpressing lentivirus plasmid was constructed. The GFP+ Cutll1 cells were detected after lentivirus infection. Consistently, the q-PCR and Western blot results showed the expression of GPR183 was elevated in Cutll1-GPR183 cells (P<0.01). The CCK-8 and Annexin V staining data showed the proliferation of Cutll1-GPR183 was inhibited (P<0.001) and the apoptosis of Cutll1-GPR183 was significant increase (P<0.01), while the cell cycle of two groups had no difference. Overall, our results indicated that GPR183 could inhibit the growth and promote the apoptosis of T-ALL Cutll1 cells and laid the foundation for the follow-up study of mechanisms.
