Fig. 1From: Differential gene expression of 3D primary human airway cultures exposed to cigarette smoke and electronic nicotine delivery system (ENDS) preparationsTotal DEGs after exposure of fully-differentiated primary NHBE to WS-CM for 4 and 24 h. Venn diagrams showing genes differentially expressed after exposure to various doses (low, medium, and high) of WS-CM at 4 h A, and 24 h B time-points. DEGs were identified with a log2 fold change > 2 or < − 2, and adjusted p-value ≤ 0.05Back to article page
