"Extracellular Vesicle DNA: Advances and Applications as a Non-Invasive Biomarker in Disease Diagnosis and Treatment".

Extracellular vesicles (EVs) are nanoscale, membrane-enclosed structures released by cells into the extracellular milieu. These vesicles encapsulate a diverse array of molecular constituents, including nucleic acids, proteins, and lipids, which provide insights into the physiological or pathological conditions of their parent cells. Despite their potential, the study of EV-derived DNA (EV-DNA) has gathered relatively limited attention.

Methylation Status at DMRs of C14MC and C19MC in Spermatozoa and Chorionic Villi of Individuals Experiencing Recurrent Spontaneous Abortions.

Recurrent spontaneous abortions (RSA) is defined as a loss of two or more consecutive clinically recognized pregnancies before the 20th week of gestation. In RSA, several causative maternal factors are known, but still, 50% of the cases remain unexplained. Evidence suggests that paternal factors are also equally important.

Long-term effects of sub-chronic exposure to L-NAME on reproductive system of male rats.

Nω-nitro-l-arginine methyl ester (L-NAME) has been utilized as a nitric oxide synthase antagonist for many years in both basic and clinical research settings to assess its therapeutic potential. Though a number of studies have shown the effect of L-NAME on testicular function, the information regarding the reversibility of these effects upon L-NAME withdrawal is limited. In the present study, male rats (68-80 days old) divided randomly into three groups received different doses of L-NAME, i.

Methylation aberrations in partner spermatozoa and impaired expression of imprinted genes in the placentae of early-onset preeclampsia.

Introduction: Disturbed paternal epigenetic status of imprinted genes has been observed in infertility and recurrent spontaneous abortions. Shallow placentation has been associated with early-onset preeclampsia. Hence, the present study aimed to investigate the methylation patterns of imprinted genes involved in placental development, in the spermatozoa of partners of women experiencing preeclampsia.

Methylation and expression of imprinted genes in circulating extracellular vesicles from women experiencing early onset preeclampsia.

Introduction: Preeclampsia (PE) is a pregnancy complication marked by high blood pressure, posing risk to maternal and fetal health. "Genomic imprinting", an epigenetic phenomenon regulated by DNA methylation at Differently Methylated Regions (DMR's), influences placental development. Research on circulating extracellular vesicles (EVs) in PE suggests them as potential source for early biomarkers, but methylation status of EV-DNA in Preeclampsia is not reported yet.
