Table 1. miRNA expression in the lung of 10-week old A/J mice of both genders, as related to exposure to ECS since birth and/or administration of aspirin after weaning.
miRNA | Treatment of mice | Main regulated functions | |||
---|---|---|---|---|---|
Sham | Aspirin | ECS | ECS + Aspirin | ||
miR-16 | 0.18 | 1.32a | 1.00a | 1.26a | Apoptosis |
miR-133 | 0.77 | 0.14a | 0.97 | 0.11a,b | Inflammation |
miR-137 | 0.49 | 1.20a | 0.77a | 1.65a,b | Cell proliferation, COX-2 negative regulator |
miR-191 | 0.89 | 1.08 | 0.43a | 1.04b | COX regulation, Cell proliferation |
miR-199b | 0.94 | 1.04 | 1.72 | 0.86b | COX activation |
miR-223 | 1.08 | 1.05 | 0.51a | 1.02 | Stress response, Protein repair, k-Ras regulation |
miR-543 | 1.17 | 0.27a | 1.85 | 1.14 | Stress response, Inflammation |
The results are expressed in FU (Fluorescence Units).
Statistical analysis: aP < 0.05 compared with Sham; bP < 0.05 compared with ECS-exposed mice in the absence of chemopreventive agents.
