Sub-chronic e-cig exposure affects protein abundance of matrix metalloproteinases (MMPs) in mouse lungs. Protein levels of several MMPs (MMP9, MMP2, MMP12, and MMP8) were measured in whole mouse lung homogenates via Western blot. Representative blot images and densitometry analyses for female (a) and male (b) mice are shown. β-actin was used as an endogenous control. Data are shown as mean ± SEM. (n = 4–5/group). * P < 0.05 between groups; $ P < 0.05, compared with air exposed WT group; & P < 0.05, compared with PG exposed WT group. # P < 0.05, compared with PG + Nic exposed WT group
