Objectives:
Altered expression of microRNAs (miRNAs) may contribute to disease vulnerability. Studies have reported the involvement of miRNA in the pathophysiology of ischemic stroke.
Methods:
We performed a meta-analysis of data from 6 studies that used a panel of miRNAs with altered expressions to diagnose ischemic stroke with the Bayesian framework. The I 2 test and Cochran's Q-statistic were used to assess heterogeneity. Funnel plots were generated and publication bias was assessed using Begg and Egger tests.
Results:
On summary receiver operating characteristics (SROC) curve analysis, the pooled sensitivity and specificity of altered miRNA expressions for diagnosis of ischemic stroke was 0.92 (95% confidence interval [CI] 0.80-0.97) and 0.83 (95% CI 0.71-0.90), respectively; the diagnostic odds ratio was 54.35 (95% CI 20.39-144.92), and the area under the SROC curve was 0.93 (95% CI 0.90-0.95).
Conclusions:
Our results showed a link between dysregulation of miRNAs and the occurrence of ischemic stroke. Abnormal miRNA expression may be a potential biomarker for ischemic stroke.
Insights
Altered microRNA (miRNA) expression is linked to ischemic stroke. This meta-analysis confirms abnormal miRNA levels as a potential diagnostic biomarker for stroke, showing high accuracy.
Area of Science:
- Biomedical Science
- Molecular Biology
- Neurology
Background:
- MicroRNAs (miRNAs) play a role in disease development, including ischemic stroke.
- Altered miRNA expression is implicated in the pathophysiology of ischemic stroke.
Approach:
- A meta-analysis was conducted on 6 studies investigating miRNA expression panels for ischemic stroke diagnosis.
- The Bayesian framework was employed, with heterogeneity assessed using I-squared and Cochran's Q-statistic.
- Publication bias was evaluated using Begg and Egger tests.
Key Points:
- The pooled sensitivity for diagnosing ischemic stroke using altered miRNA expression was 0.92 (95% CI 0.80-0.97).
- The pooled specificity was 0.83 (95% CI 0.71-0.90).
- The area under the summary receiver operating characteristic (SROC) curve was 0.93 (95% CI 0.90-0.95), indicating strong diagnostic performance.
Conclusions:
- A significant association exists between miRNA dysregulation and ischemic stroke occurrence.
- Abnormal miRNA expression represents a promising potential biomarker for the diagnosis of ischemic stroke.

Preload refers to the degree of stretch on the heart before it contracts. It's analogous to the stretching of a rubber band; the more it's stretched, the more forcefully it snaps back. This concept is encapsulated in the Frank-Starling law of the...
