Bar graphs of the normalized abundances of (A) TIMP1 expression profile across the control groups, 3 h and 24 h exposures, (B) MMP-9 at the 3 h and 24 h marks, and (C) Ratios between the expression levels of MMP-9 vs. TIMP1. Significant dysregulation of TIMP1 and MMP9 (adj. p-value ≤ 0.05) is shown by * and significant changes in the ratio (p-value ≤ 0.05, students t-test) are indicated by *.
