Expanded alleles of the FMR1 gene are related to unexplained recurrent miscarriages
Up to 50% of recurrent miscarriage cases in women occur without an underlying etiology. In the current prospective case-control study, we determined the impact of CGG trinucleotide expansions of the fragile-X mental retardation 1 (FMR1) gene in 49 women with unexplained recurrent miscarriages. Case group consisted of women with two or more unexplained consecutive miscarriages. Blood samples wer...
متن کاملPolymorphisms in the ACE and PAI-1 genes are associated with recurrent spontaneous miscarriages.
BACKGROUND Successful pregnancies require fine tuning of fibrinolytic activities in order to secure fibrin polymerization and stabilization of the placental basal plate as well as to prevent excess fibrin deposition in placental vessels and intervillous spaces. Fibrinolysis is tightly regulated by plasminogen activator inhibitor-1 (PAI-1). Endothelial PAI-1 synthesis is induced by angiotensin I...
متن کاملRelationship between sperm protamine deficiency and apoptosis in couples with unexplained repeated spontaneous abortions
BACKGROUND Etiology of more than half of Recurrent Spontaneous Abortion. The etiology of more than 50 percent of Recurrent Spontaneous Abortions (RSA) cases has been remained unexplained. It is supposed that RSA may have "paternal effect" due to supply 50% of embryonic genomic content by male gamete. OBJECTIVE The aim of present study was to evaluate the role of sperm apoptosis and protamine ...
متن کاملProgesterone in Women with Recurrent Miscarriages.
To the Editor: In summarizing their well-executed randomized trial, Progesterone in Recurrent Miscarriages (PROMISE), Coomarasamy et al. (Nov. 26 issue)1 state that there is no evidence of benefit from progesterone supplementation “in the first trimester” of pregnancy among women who have had three or more miscarriages. We wish to clarify three points. First, the trial did not address progester...
متن کاملComparison of Protamine 1 to Protamine 2 mRNA Ratio and YBX2 gene mRNA Content in Testicular Tissue of Fertile and Azoospermic Men
Background Although aberrant protamine (PRM) ratios have been observed in infertile men, the mechanisms that implicit the uncoupling of PRM1 and PRM2 expression remain unclear. To uncover these mechanisms, in this observational study we have compared the PRM1/PRM2 mRNA ratio and mRNA contents of two regulatory factors of these genes. MaterialsAndMethods In this experimental study, sampling was ...
