The Regulation Of Dna Methylation In Mammalian Development And Cancer, Nicolas Veland
The Regulation Of Dna Methylation In Mammalian Development And Cancer, Nicolas Veland
Dissertations & Theses (Open Access)
DNA methylation is an essential epigenetic modification in mammals, as it plays important regulatory roles in multiple biological processes, such as gene transcription, maintenance of chromosomal structure and genomic stability, genomic imprinting, retrotransposon silencing, and X-chromosome inactivation. Dysregulation of DNA methylation is associated with various human diseases. For example, cancer cells usually show global hypomethylation and regional hypermenthylation, which have been implicated in genomic instability and tumor suppressor silencing, respectively. Although great progress has been made in elucidating the biological functions of DNA methylation over the last several decades, how DNA methylation patterns and levels are regulated and dysregulated is …
Epigenetic Modifications Of Human Placenta Associated With Preterm Birth, Drissa Toure
Epigenetic Modifications Of Human Placenta Associated With Preterm Birth, Drissa Toure
Theses & Dissertations
Preterm birth is a complex multifactorial process. Despite the well-known role of the placenta in supporting the fetal development and maternal-fetal tolerance, the placental epigenetic modifications and preterm birth (PTB) remains poorly understood and under investigated. Various maternal and environment factors can influence epigenetic programming during fetal development to affect the functioning and structures of organs, including the placenta, which can lead to adverse pregnancy outcomes, including PTB. The understanding of the placental epigenetic alterations and maternal determinants associated with PTB are apparently indispensable for the development of actual diagnosis and methods of prevention and treatment of premature labor. The …
