| Outline of Final Research Achievements |
We focused on microRNA expressions in macrophages and monocytes in the presence of acute lung injury (ALI) or acute respiratory distress syndrome (ARDS). In the first step, we prepared a macrophage (and THP-1 cell) inflammatory model by lipopolysaccharide (LPS) exposure, and analyzed microRNA expressions. In the second step, we investigated the changes in intracellular signaling molecules (e.g., TNF-α) with the transgenesis of microRNA using Nucleofector. The results of the first step showed the altered expression of miR-21 based on comprehensive analysis and the real-time PCR method. MiR-21 transgenesis induced the increased expressions of IL-10 and P-Akt (P308) proteins based on Western blotting.
