Fig. 5. Suppression of STAT3 contributes to the protective effects of miR-297 on HUVECs. (A) HUVECs were cotransfected with miR-297 mimics and si-STAT3. After administration of 100 ng/mL LPS for 24 h, all proteins were measured by Western blot. (B) Apoptosis-related proteins were measured by Western blot. Each experiment was performed in triplicate independently. Asterisks indicated statistically significant differences. Data was represented as means ± SD. * P < 0.001, v.s. control.
