MiR-155 was upregulated in LPS-injured BV2 cells. BV2 cells were treated with 10 μg/ml LPS for 5 h. Quantitative RT-PCR was used to measure relative expression of miR-155. a Expression of miR-155 in LPS-treated cells and control cells; b Expression of miR-155 in cells transfected with miR-155 mimic, miR-155 inhibitor, or their correspondingly negative controls (scramble and inhibitor control). n = 3. LPS: lipopolysaccharide; RT-PCR: reverse transcription polymerase chain reaction. *P < 0.05, **P < 0.01, ***P < 0.001
