Maternal and neonatal plasma microRNA biomarkers for fetal alcohol exposure in an ovine model.

ABSTRACT:

Background

Plasma or circulating miRNAs (cir miRNAs) have potential diagnostic value as biomarkers for a range of diseases. Based on observations that ethanol (EtOH) altered intracellular miRNAs during development, we tested the hypothesis that plasma miRNAs were biomarkers for maternal alcohol exposure, and for past in utero exposure, in the neonate.

Methods

Pregnant sheep were exposed to a binge model of EtOH consumption resulting in an average peak blood alcohol content of 243 mg/dl, for a third-trimester-equivalent period from gestational day 4 (GD4) to GD132. MiRNA profiles were assessed by quantitative PCR analysis in plasma, erythrocyte, and leukocytes obtained from nonpregnant ewes, and plasma from pregnant ewes 24 hours following the last binge EtOH episode, and fro
