Clustering patterns of transcriptomic profiles and DEGs identification (a) Batch effect corrected-PCA result. PCA showed a distinct difference between the control and the exposure groups. (b) Volcano plot results of DEGs by each exposure groups. (c) Venn diagram of the DEGs among the formaldehyde exposure groups. (d) Hierarchical clustering heatmap of the common DEGs. All analyses were performed using R software (version 3.6.3).
