Summary of "Maternal n-3 PUFAs deficiency during pregnancy inhibits neural progenitor cell proliferation in fetal rat cerebral cortex."

The aim of this study was to evaluate the in vivo impacts of maternal n-3 polyunsaturated fatty acids (PUFAs) deficiency during pregnancy on the proliferation of neural progenitor cells (NPCs) in the developing cerebral cortex of fetal rats. Our results showed that about 5 weeks of maternal dietary n-3 PUFAs deprivation resulted in a substantial n-3 PUFA deficiency in fetal rat cerebral cortex. Importantly, by two survival schemes and two quantitative methods, we found that maternal intake of n-3 PUFAs deficient diet during the gestation significantly inhibited the proliferation of NPCs in fetal rat cerebral cortex. Moreover, the decreased cortical NPCs proliferation induced by nutritional n-3 PUFAs restriction did not originate from the increased NPCs apoptosis. Finally, our observations indicated that the down-regulation of cyclin E protein might be involved in the inhibitory effects of maternal n-3 PUFAs deficient diet on the proliferation of cortical NPCs. These findings highlight the importance of maternal intake of appropriate n-3 PUFAs and deepen our understanding of the exact effects of n-3 PUFAs on mammalian brain development.

Medical and Biotech [MESH] Definitions

Pregnancy in which the mother and/or FETUS are at greater than normal risk of MORBIDITY or MORTALITY. Causes include inadequate PRENATAL CARE, previous obstetrical history (ABORTION, SPONTANEOUS), pre-existing maternal disease, pregnancy-induced disease (GESTATIONAL HYPERTENSION), and MULTIPLE PREGNANCY, as well as advanced maternal age above 35.

Maternal deaths resulting from complications of pregnancy and childbirth in a given population.

Glycoproteins with the electrophoretic mobility of BETA-GLOBULINS, secreted by the placental TROPHOBLASTS into the maternal bloodstream during PREGNANCY. They can be detected 18 days after OVULATION and reach 200 mg/ml at the end of pregnancy. They are associated with fetal well-being.

Blocking of maternal circulation by AMNIOTIC FLUID that is forced into uterine VEINS by strong UTERINE CONTRACTION near the end of pregnancy. It is characterized by the sudden onset of severe respiratory distress and HYPOTENSION that can lead to maternal DEATH.

The age of the mother in PREGNANCY.
