1. ABSTRACT

In mammals, thousands of non-protein-coding RNAs (ncRNAs), including microRNAs, endogenous small interfering RNAs, PIWI-interacting RNAs and mRNA-like long ncRNAs, have been identified. These RNAs modulate gene expression at transcriptional, post-transcriptional and epigenetic levels in many developmental and metabolic processes. Increasing evidence shows that ncRNAs are also linked to embryo implantation through regulating the expression of certain key genes and pathways. In this paper, we summarized the recent literatures on the ncRNAs involved in embryo implantation.
