Fig. 3. The association of rs884304 with IFN-γ induced promoter activity and CXCL9 recovery.

Fig. 3

A In patients, high-risk genotypes (AA + AG) of genetic risk group A (rs884304) were associated with significantly higher day +28 serum CXCL9 levels, but not with pre-transplant CXCL9. B In luciferase reporter assays, IFN-γ activation revealed that the constructs carrying variant allele of rs884304 (P < 0.001), rs884004 (P < 0.001), and the one carrying variant alleles of all the three SNPs (P = 0.001), but not rs2869462, were associated with significantly reduced suppressive effect of CsA compared to the wild-type construct. The results were collected from three independent experiments. Luciferase activity was normalized to 1 relative to the WT and all data were plotted as the mean ± SEM. C Similar to (B), with FK506 (tacrolimus) as calcineurin inhibitor. Results were collected from three independent experiments. Luciferase activity was normalized to 1 relative to the WT and all data were plotted as the mean ± SEM. D Recovery rates of CXCL9 serum levels in patients from the lowest value post alloSCT until day 28+ in the presence of calcineurin inhibitors (slope CXCL9) was higher in the genetic high-risk group. n.s. not significant; *P ≤ 0.05; ***P < 0.001.
