Abstract:
MicroRNAs (miRNAs) are small non-coding RNAs that play critical roles in regulating host gene expression. Recent studies have indicated a role of miRNAs in the pathogenesis of gestational diabetes mellitus (GDM), a common pregnancy-related disorder characterized by impaired glucose metabolism. Aberrant expression of miRNAs has been observed in the placenta and/or maternal blood of GDM patients, suggesting their potential use as biomarkers for early diagnosis and prognosis. Additionally, several miRNAs have been shown to modulate key signaling pathways involved in glucose homeostasis, insulin sensitivity, and inflammation, providing insights into the pathophysiology of GDM. This review summarizes the current knowledge on the dynamics of miRNA in pregnancy, their role in GDM as well as their potential as diagnostic and therapeutic targets.
Insights
MicroRNAs (miRNAs) are key regulators in pregnancy, with altered levels linked to gestational diabetes mellitus (GDM). These small RNAs show potential as diagnostic biomarkers and therapeutic targets for GDM.
Area of Science:
- Molecular Biology
- Endocrinology
- Reproductive Medicine
Background:
- MicroRNAs (miRNAs) are small non-coding RNAs regulating gene expression crucial for biological processes.
- Gestational diabetes mellitus (GDM) is a pregnancy complication affecting glucose metabolism.
- Emerging evidence implicates miRNAs in GDM pathogenesis, with altered expression in GDM patients.
Purpose of the Study:
- To review the role of miRNAs in pregnancy.
- To explore the involvement of miRNAs in gestational diabetes mellitus.
- To discuss the potential of miRNAs as diagnostic and therapeutic targets for GDM.
Main Methods:
- Literature review of studies on miRNA dynamics in pregnancy and GDM.
- Analysis of research on miRNA expression in GDM patients (placenta and maternal blood).
- Examination of studies investigating miRNA modulation of GDM-related pathways.
Main Results:
- miRNAs play significant roles in normal pregnancy and GDM development.
- Aberrant miRNA expression is a hallmark of GDM in placental and maternal blood samples.
- Specific miRNAs influence glucose homeostasis, insulin sensitivity, and inflammation in GDM.
Conclusions:
- miRNAs are dynamically regulated during pregnancy and are implicated in GDM.
- miRNAs represent promising biomarkers for early GDM diagnosis and prognosis.
- Targeting miRNAs offers potential therapeutic strategies for managing GDM.
