MicroRNA Profiles in Serum and Extracellular Vesicles Associated with Neurodevelopmental Changes in Central Precocious Puberty

Overview

This study identifies distinct microRNA profiles in serum and extracellular vesicles from female patients with central precocious puberty (CPP).

Background

Central precocious puberty (CPP) is characterized by the premature activation of the hypothalamic-pituitary-gonadal (HPG) axis, primarily affecting girls. Understanding the molecular mechanisms behind CPP is crucial.

Data Highlights

MicroRNAExpression Change
miR-125a-5pDecreased
miR-125b-5pDecreased
miR-99b-5pDecreased
miR-148a-3pIncreased in EVs

Key Findings

  • Ten microRNAs were identified with significantly altered expression levels in CPP patients.
  • Pathway enrichment analysis indicated involvement in neurodevelopment, growth regulation, and cellular maturation.
  • RT-qPCR validation confirmed decreased levels of miR-125a-5p, miR-125b-5p, and miR-99b-5p in CPP serum samples.
  • All selected microRNAs were detectable in serum-derived extracellular vesicles.
  • miR-148a-3p showed a significant increase specifically in the EV-associated fraction of CPP samples.

Clinical Implications

The findings indicate altered microRNA profiles in CPP patients.

Conclusion

This research provides insights into the microRNA landscape associated with central precocious puberty.
