Aberrantly expressed genes in the oral epithelial cells of vapers and smokers as compared to non-users. (A) Numbers of upregulated and downregulated gene transcripts in vapers and smokers are indicated. Venn diagrams of all dysregulated genes (B) and cancer-related dysregulated genes (C) in vapers and smokers are shown. DEGs = differentially expressed genes. Data are from our previous publication (Ref. [13]). Detailed descriptions of data pre-processing, alignment, quantification, and differential expression analysis are provided in Ref. [13].
