Based on the GPL14550 dataset, upregulated TET2 expression was detected in IPF rather than healthy BAL cells (p < .05; Figure 2(a)), and the statistical significance of the expression levels of the remaining nine m5CRGs between the IPF group and healthy group was not observed (p > .05; Figure 2(a)). This evidence concerns the gene TET2 and idiopathic pulmonary fibrosis.
