Abstract: Objective To explore the role of miR-29c in rat leptomeningeal fibrosis after subarachnoid hemorrhage (SAH). Methods A total of 26 healthy Sprague-Dawley (SD) rats were randomly divided into sham group (n=6), empty lentiviral group (n=8), and LV-rno-miRNA-29c group (n=12). 5 μL saline, empty lentivirus and LV-rno-miRNA-29c were respectively injected into the lateral cerebral ventricle of rats in each group. The SAH models were induced by injecting autologous blood twice into the cisterna magna, and 21 days later the rats were killed. Realtime PCR was used to detect the expressions of TGF-β1 and miR-29c. Masson staining was performed to observe collagen fiber. ELISA was adopted to measure the level of PICP in CSF. Results Increased TGF-β1 and decreased miR-29c were detected. The upregulation of miR-29c could significantly reduce the expressions of PICP in CSF and collagen in leptomeninge. Conclusion High expression of miR-29c may have potential therapeutic effects for leptomeningeal fibrosis by inhibiting collagen synthesis after SAH.
