Abstract
The invention relates to a method of assessing pregnancy outcome. The inventors investigated endometrial miRNAs associated with pregnancy outcome by studying miRNAs associated with endometrial receptivity, implantation failure and embryo miscarriage. They performed a miRNomic study to find miRNAs that are differentially expressed according to the endometrial receptivity status, compared the endometrial miRNome between receptive patients with negative beta-hCG and receptive patients with positive beta-hCG, and compared the endometrial miRNome between receptive patients with a miscarriage between 8-12 weeks of amenorrhoea and receptive patients with a live birth. They demonstrated miRNA differential expression in endometrial samples according to the pregnancy outcome. Thus, the invention relates to a method of assessing pregnancy outcome of a patient, comprising a step of measuring in a biological sample obtained from the patient the expression level of at least one miRNA selected from the group consisting of miR-455-3 p, miR-4423-3p, miR-4445-3p, miR-3128, miR-3201, let-7b-5p, let-7c-5p, miR-4534, miR-214-3p, miR-15b-5p, miR-424-3p, miR-181a-5p, miR-574-3p, miR-92a-3 p, miR-320c, let-7d-5p, miR-125a-5p, miR-320a, miR-320b and let-7f-5p.
