Figure 3From: DNA methylation of the allergy regulatory gene interferon gamma varies by age, sex, and tissue type in asthmaticsComparison of IFNγ promoter methylation levels by tissue type and CpG site stratified by sex. n = 31 males, n = 43 females. Males had significantly higher CD4+ methylation levels at both CpG sites (-186: P < 0.01, -54: P = 0.02), however, sex-specific differences were not identified in buccal cells (-186: P = 0.14, -54: P = 0.60).Back to article page
