From: DNA methylation at modifier genes of lung disease severity is altered in cystic fibrosis
HMOX1 gene expression in blood samples. a The box plots represent the relative expression of HMOX1 in CF patients with different lung disease and controls (Kruskal-Wallis p = 0.39). CFM mild CF patient, CFI intermediary CF patient, CFS severe CF patient. b Correlation between gene expression and mean DNA methylation levels in blood samples from CF patients and controls. Whole cohort (Spearman’s r = 0.09, p = 0.48); controls (Spearman’s r = −0.14, p = 0.62); CF patients (Spearman’s r = 0.08, p = 0.58)
