Abstract
Recurrent pregnancy loss (RPL) or recurrent miscarriage is the failure of pregnancy before 20-24 weeks that influences
around 2-5% of couples. Several genetic, immunological, environmental and physical factors may influence
RPL. Although various traditional methods have been used to treat post-implantation failures, identifying the mechanisms
underlying RPL may improve an effective treatment. Recent evidence suggested that gene expression alterations
presented essential roles in the occurrence of RPL. It has been found that long non-coding RNAs (lncRNAs) play
functional roles in pregnancy pathologies, such as recurrent miscarriage. lncRNAs can function as dynamic scaffolds,
modulate chromatin function, guide and bind to microRNAs (miRNAs) or transcription factors. lncRNAs, by targeting
various miRNAs and mRNAs, play essential roles in the progression or suppression of RPL. Therefore, targeting
lncRNAs and their downstream targets might be a suitable strategy for diagnosis and treatment of RPL. In this review,
we summarized emerging roles of several lncRNAs in stimulation or suppression of RPL.
