Non-Coding RNAs Regulate Placental Trophoblast Function and Participate in Recurrent Abortion

Area of Science:

• Reproductive biology
• Molecular genetics
• Biochemistry

Background:

• Recurrent spontaneous abortion (RSA) is a complex pregnancy complication with rising incidence.
• Non-coding RNAs (ncRNAs) are increasingly recognized for their significant roles in RSA pathogenesis.
• Abnormal ncRNA expression impacts placental trophoblast cell functions, potentially leading to RSA.

Purpose of the Study:

• To review the function and mechanisms of key ncRNAs (miRNAs, lncRNAs, circRNAs) in regulating placental trophoblasts.
• To explore the potential of ncRNAs as diagnostic and predictive biomarkers for RSA.
• To provide insights for future research directions in RSA and ncRNA biology.

Main Methods:

• Literature review of recent research on ncRNAs in recurrent spontaneous abortion.
• Analysis of studies focusing on microRNAs (miRNAs), long non-coding RNAs (lncRNAs), and circular RNA (circRNA) functions.
• Examination of ncRNA regulatory roles in placental trophoblast cell processes.

Main Results:

• NcRNAs significantly influence placental trophoblast growth, migration, and invasion.
• Dysregulation of ncRNAs affects critical cellular processes like cell cycle, apoptosis, and epithelial-mesenchymal transition.
• Specific ncRNAs like miRNAs, lncRNAs, and circRNAs are implicated in RSA development.

Conclusions:

• NcRNAs are vital regulators of placental trophoblast function and are implicated in the pathophysiology of RSA.
• MicroRNAs, lncRNAs, and circRNAs represent promising targets for understanding and managing RSA.
• Further research into ncRNAs could lead to novel diagnostic and predictive biomarkers for recurrent spontaneous abortion.
