Gene differential expression analysis. (A) Differential expression of m7G-regulated genes in COPD patients and normal controls. (B) Differential expression boxplot of the 25 identified m7G regulators. The t test was used to analyze the difference in the expression levels of m6A regulators. Compared with the controls, * p < 0.05, ** p < 0.01, and *** p < 0.001.
