Genomic Imprinting and Inheritance

36.2K
Diploid organisms inherit genetic material through chromosomes from both parents. Copies of the same gene are known as alleles. In most cases, both alleles are simultaneously expressed and allow various cellular processes to function optimally. If one of the alleles is missing or mutated, the expression of the other allele can compensate; however, this is not true for all genes.
The expression of some genes depends on which parent passed the gene to the offspring, through a phenomenon known as...

Epigenetic Regulation01:37

Epigenetic Regulation

3.5K
Epigenetic changes alter the physical structure of the DNA without changing the genetic sequence and often regulate whether genes are turned on or off. This regulation ensures that each cell produces only proteins necessary for its function. For example, proteins that promote bone growth are not produced in muscle cells. Epigenetic mechanisms play an essential role in healthy development. Conversely, precisely regulated epigenetic mechanisms are disrupted in diseases like cancer.

Teratogenicity01:07

Teratogenicity

3.7K
The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...

This summary is machine-generated.

Epigenetic modifications in fetal membranes regulate gene expression crucial for pregnancy maintenance and birth. These epigenetic changes, including DNA methylation and non-coding RNAs, are vital for normal pregnancy and can be altered by disease and environmental factors.

Area of Science:

  • Reproductive biology
  • Epigenetics
  • Genomics

Background:

  • Fetal membrane cell function during pregnancy is governed by gene expression patterns.
  • Epigenetic mechanisms like DNA methylation and histone modifications control chromatin structure and gene activity.
  • Non-coding RNAs play a role in stabilizing gene expression and facilitating cellular phenotype transitions.

Purpose of the Study:

  • To review current knowledge on epigenetic gene regulation in the amnion, chorion laeve, and choriodecidua.
  • To discuss the interplay between gene expression and epigenetic modifications in pregnancy.
  • To explore the association of epigenetics with normal pregnancy, parturition, and complications.

Main Methods:

  • Review of existing literature on fetal membrane epigenetics.
  • Analysis of data from clinical samples and cell culture models.
  • Discussion of epigenetic markers such as DNA methylation, histone modifications, and non-coding RNAs.

Main Results:

  • Epigenetic events are strongly linked to the phenotypic changes in fetal membranes throughout pregnancy.
  • These epigenetic modifications appear to drive and consolidate cellular changes as pregnancy progresses.
  • Environmental factors and disease states can leave epigenetic footprints, potentially leading to adverse pregnancy outcomes.

Conclusions:

  • Epigenetic regulation is fundamental to fetal membrane cell function during pregnancy.
  • Epigenetic footprints may serve as indicators of exposures and contribute to pregnancy complications.
  • Further research is essential to unlock the full basic and translational potential of fetal membrane epigenetics.
