Fig. 5From: Hypermethylation of the glutathione peroxidase 4 gene promoter is associated with the occurrence of immune tolerance phase in chronic hepatitis BThe associations between mRNA level and methylation level of GPX4 in PBMCs and mRNA level of STING in PBMCs, and IFN-β expressive in serum. Significant correlation was observed between the mRNA level of GPX4 and mRNA level of STING in PBMCs (a Spearman’s r = 0.4203, P<0.0001), and IFN-β expressive in serum (b Spearman’s r = 0.3469, P<0.0001). And significant correlation was observed between the PMR value of GPX4 promoter and mRNA level of STING in PBMCs (c Spearman’s r = − 0.4508, P<0.0001), and IFN-β serum expression level (d Spearman’s r = − 0.2255, P = 0.0081),ns, P>0.05; *, P ≤ 0.05; **, P ≤ 0.01; ***, P ≤ 0.001; ****, P ≤ 0.0001Back to article page
