Abstract
OBJECTIVES: We analyzed the relationship between plasma miR-143/145 and serum MMP-9 in patients with unruptured or ruptured intracranial aneurysms (IAs) to identify new biomarkers for predicting rupture in IAs. PATIENTS AND METHODS: We prospectively enrolled 24 consecutive patients, including seven patients without IAs as a control group, nine patients with unruptured IAs, and eight patients with ruptured IAs (enrolled within 3 days after rupture). Plasma miR-143/145 and MMP-9 were measured in blood samples collected from the femoral artery. Spearman ρ values were used for correlation analyses. RESULTS: The level of plasma miR-143/145 in patients with ruptured IAs was significantly lower than that of the control group. Moreover, patients with ruptured IAs had a significantly higher level of serum MMP-9 compared with that in patients with unruptured IAs and in control patients. A lower level of plasma miR-143 was significantly correlated with a lower level of plasma miR-145 (Spearman ρ = 0.771; P < 0.0001). CONCLUSION: These findings showed that a lower of plasma miR-143/145 is potentially associated with IA formation, while higher serum MMP-9 levels may be associated with IA rupture and could serve as a useful biomarker for the evaluation of IA rupture.
