The role of miR-492 in the regulation of OK blood group antigen expression on red blood cells
OBJECTIVE: To investigate whether miR-492 is involved in the post-transcriptional regulation of OK blood group antigen expression on red blood cells.
METHODS: Two 3'-UTR fragments of the BSG gene were synthesized with a chemical method, which respectively encompassed the BSG rs8259 TT or BSG rs8259 AA sites. The fragments were added with Xho I and Not I restriction enzyme cutting sites at both ends and cloned into a pUC57 vector, which in turn was constructed into a psiCHECK-2 vector and verified by sequencing. K562 cells were transfected with various combinations of miR-492 mimic and constructed psiCHECK2-BSG-T or psiCHECK2-BSG-A recombinant plasmid. A blank control group was set up. Each transfection experiment was repeated three times. The activity of Renilla reniformis luciferase was determined and normalized with that of firefly luciferase, and detected with a dual-luciferase reporter assay system. The data were subjected to statistical analysis.
RESULTS: The sequencing results confirmed that the recombinant psiCHECK2 plasmids containing the BSG rs8259 TT or rs8259 AA sites were constructed successfully. The results of dual-luciferase report gene detection showed that the miR-492 mimic could significantly inhibit psiCHECK2-BSG-T at a concentration over 100 nmol/L. However, it could not inhibit psiCHECK-BSG-A.
CONCLUSION: miR-492 may be involved in the regulation of OK antigen expression on red blood cells with the BSG rs8259 TT genotype.
