目的

分析miR-200b-3p 在海水吸入性急性肺损伤(acute lung injury, ALI) 中的作用及机制。

方法

选取32 只健康SD 大鼠,分为空白对照组、海水刺激组、miR-200b-3p antagomir 预处理组和antag NC 预处理组,每组8 只,构建海水吸入性肺损伤大鼠及大鼠肺微血管内皮细胞(rat pulmonary microvascular endothelial cells, RPMVECs)模型。 观察肺组织湿干比(W/D)、伊文思蓝法检测肺微血管通透性,Western blot 检测低氧诱导因子-1(hypoxia inducible factor-1, HIF-1α)及血管内皮生长因子(vascular endothelial growth factor, VEGF)的表达变化,采用双荧光素酶报告基因实验验证HIF-1α 和miR-200b-3p 的作用关系。

结果

海水干预4 h 后,大鼠肺组织湿干比(W/D)及通透性明显增加,在肺组织及细胞模型中miR-200b-3p 表达明显增高,HIF-1α 表达出现升高,VEGF 表达同时也出现上升。 而抑制miR-200b-3p 的表达后,肺水肿得到明显的减轻,肺组织及细胞模型中HIF-1α 表达出现下降,VEGF表达也出现下降。 双荧光素酶报告基因验证miR-200b-3p 直接靶向作用于HIF-1α。 与空白对照组对比,海水刺激组大鼠肺组织中HIF-1α 及VEGF 表达增加,RPMVECs 细胞中HIF-1α 及VEGF 表达增加。

结论

增加表达的miR-200b-3p 在海水吸入性肺损伤肺组织水肿的发展中起到关键作用,这种作用是通过调节HIF-1α/VEGF 通路形成的。

Objective

To analyze the role and mechanism of miR-200b-3p in seawater inhalation acute lung injury (ALI).

Methods

Thirty-two healthy SD rats were selected and divided into blank control group, seawater stimulation group, miR-200b-3p antagomir pretreatment group and antag NC pretreatment group, with 8 rats in each group. The rat pulmonary microvascular endothelial cells (RPMVECs) model of seawater inhalation lung injury and rat pulmonary microvascular endothelial cells were constructed. Wet-dry ratio(W/D) of lung tissue was observed, and microvascular permeability of lung was detected by Evans blue method. Western blot analysis of the expression of -hypoxia inducible factor-1(HIF-1α) and vascular endothelial growth factor (VEGF) were detected. Dual luciferase reporter gene assay was used to verify the relationship between HIF-1α and miR-200b-3p.

Results

After seawater treatment for 4 h, the wet-dry ratio(W/D) and permeability of lung tissue were significantly increased, and the expression of miR-200b-3p, HIF-1α and VEGF were significantly increased in lung tissue and cell models. However, inhibition of the expression of miR-200b-3p significantly alleviated pulmonary edema, the expression of HIF-1α and VEGF were decreased in lung tissues and cell models. Dual luciferase reporter gene verified that miR-200b-3p directly targeted HIF-1α. Compared with blank control group, the expressions of HIF-1α and VEGF in lung tissue and HIF-1α and VEGF in RPMVECs cells were increased in seawater stimulated group.

Conclusion

Increased expression of miR-200b-3p plays a key role in the development of pulmonary edema induced by seawater aspiration injury,which is mediated by the HIF-1α/VEGF pathway.
