Animal Mitochondrial Genetics02:59

Animal Mitochondrial Genetics

8.5K
Among all the organelles in an animal cell, only mitochondria have their own independent genomes. Animal mitochondrial DNA is a double-stranded, closed-circular molecule with around 20,000 base pairs. Mitochondrial DNA is unique in that one of its two strands, the heavy, or H, -strand is guanine rich, whereas the complementary strand is cytosine rich and called the light, or L, -strand. Compared to nuclear DNA, mitochondrial DNA has a very low percentage of non-coding regions and is marked by...

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...

Area of Science:

  • Reproductive biology
  • Mitochondrial biology
  • Perinatal medicine

Background:

  • Poor maternal nutrition, hypoxia, and obesity elevate risks for pregnancy complications like pre-eclampsia and gestational diabetes.
  • The placenta is crucial for fetal development, acting as an exchange interface and endocrine hub.
  • Mitochondria, the cell's energy producers, are vital for placental function and respond to environmental cues.

Purpose of the Study:

  • To review the role of placental mitochondria in mediating the effects of adverse environmental conditions on pregnancy.
  • To understand how mitochondrial structure and function are altered in complicated pregnancies and poor gestational environments.
  • To highlight the significance of placental mitochondria in determining pregnancy outcomes.

Main Methods:

  • Review of existing literature on placental mitochondria in humans and experimental animals.
  • Analysis of studies examining mitochondrial structure and function under various gestational conditions.
  • Synthesis of data linking environmental factors, placental mitochondria, and pregnancy outcomes.

Main Results:

  • Mitochondrial function is altered in response to poor maternal environments.
  • Changes in placental mitochondrial structure and function are associated with pregnancy complications.
  • Mitochondria play a significant role in placental physiology and fetal development.

Conclusions:

  • Placental mitochondria are critical in adapting to environmental challenges during pregnancy.
  • Mitochondrial dysfunction in the placenta contributes to adverse pregnancy outcomes.
  • Targeting placental mitochondrial health may offer strategies to improve maternal and offspring health.
