Tobacco smoke exposure alters miRNA levels in mouse lungs. Groups of mice were exposed to tobacco smoke as described in the Methods. Total RNA was prepared from lung tissue and levels of miRNAs (A) let-7a, (B) miR-93, (C) let-7g, and (D) miR-29a were determined by RT-PCR. N=4–6 samples per group. **P≤0.01, ***P≤0.0001 by t-test.
