The Effect Of Maternal Obesity On The Regulation Of Gene Expression And Cell Fate During Embryonic Cortical Neurogenesis, Thilina Thejinda Alawathugoda

Dissertations

Neurodevelopmental disorders have their roots in multifaceted origins that manifest during the earliest stages of embryonic growth, often linked to sophisticated gene regulation dynamics. A perturbed metabolic environment, specifically owing to maternal obesity, can lead to dyslipidemia, subsequently threatening the optimal development of the embryonic central nervous system. Growing evidence suggests that such metabolic irregularities during pregnancy can alter neurogenesis pathways, thus predisposing the developing fetus to neurodevelopmental disorders. One of the primary avenues through which these disruptions may occur is through alterations in histone modifications resulting from fluctuations in the expression of histone modifying enzymes or the availability of …
