ObjectiveInvestigating the potential role of CYR61 in recurrent pregnancy loss is critical for developing diagnostic approaches and treatments for recurrent pregnancy loss.MethodsIn this prospective case-control study, we have investigated the expression patterns of CYR61 in blood samples from participants with recurrent pregnancy loss in their medical history and control group (n=20 vs n=10). Peripheral blood mononuclear cells from study and control groups were isolated and the expression patterns of the CYR61 gene were determined by real-time semi-quantitative reverse transcriptase PCR.ResultsA significant decrease in CYR61 gene expression was demonstrated in patients with two or more clinically recognized miscarriages compared with patients without miscarriages or with a history of miscarriage (p<0.01), which may make the CYR61 gene a potential candidate for predicting the risk of recurrent pregnancy loss.DiscussionThis study provides a basis for a detailed investigation of candidate biomarkers and molecular players involved in the development of recurrent pregnancy loss and for the development of potential treatment approaches to prevent recurrent pregnancy loss.
