Noncoding RNAs in Unexplained Recurrent Spontaneous Abortions and Their Diagnostic Potential

Area of Science:

• Reproductive Biology
• Molecular Genetics
• Biomarker Discovery

Background:

• Unexplained recurrent spontaneous abortion (URSA) involves consecutive pregnancy losses before 20 weeks despite normal screening.
• The cellular and molecular mechanisms underlying URSA remain incompletely understood.
• Noncoding RNAs (ncRNAs) are crucial regulators of gene expression with potential roles in reproductive health.

Purpose of the Study:

• To review the current knowledge on noncoding RNAs (ncRNAs) implicated in unexplained recurrent spontaneous abortion (URSA).
• To explore the potential of ncRNAs as diagnostic biomarkers for URSA.
• To investigate the mechanistic roles of ncRNAs in the pathogenesis of URSA.

Main Methods:

• This study is a narrative review of existing literature.
• The review focuses on research investigating ncRNAs in the context of URSA.
• Literature search included studies on ncRNA function, stability, and association with pregnancy loss.

Main Results:

• Noncoding RNAs (ncRNAs) play significant roles in transcriptional regulation and gene expression.
• The stability of ncRNAs in circulation and at the maternal-fetal interface suggests their utility as biomarkers.
• Emerging evidence links specific ncRNAs to the pathogenesis of unexplained recurrent spontaneous abortion (URSA).

Conclusions:

• Noncoding RNAs (ncRNAs) represent a promising area for understanding the pathogenesis of unexplained recurrent spontaneous abortion (URSA).
• ncRNAs hold potential for the development of novel diagnostic biomarkers for URSA.
• Further research into ncRNA mechanisms is crucial for advancing URSA diagnostics and therapeutics.
