Animal Mitochondrial Genetics02:59

Animal Mitochondrial Genetics

7.5K
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...

Mitochondrial Membranes01:45

Mitochondrial Membranes

8.6K
A single mitochondrion is a bean-shaped organelle enclosed by a double-membrane system. The outer membrane of mitochondria is smooth and contains many porins - the integral membrane transporters. Porins enable free diffusion of ions and small uncharged molecules through the outer mitochondrial membrane but limit the transport of molecules larger than 5000 Daltons. Further, the outer mitochondrial membrane forms a unique structure called membrane contact sites with other subcellular organelles,...

Teratogenicity01:07

Teratogenicity

2.3K
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...

Electron Transport Chain: Complex I and II01:46

Electron Transport Chain: Complex I and II

11.5K
The mitochondrial electron transport chain (ETC) is the main energy generation system in the eukaryotic cells. However, mitochondria also produce cytotoxic reactive oxygen species (ROS) due to the large electron flow during oxidative phosphorylation. While Complex I is one of the primary sources of superoxide radicals, ROS production by Complex II is uncommon and may only be observed in cancer cells with mutated complexes.
ROS generation is regulated and maintained at moderate levels necessary...

Mitochondria01:37

Mitochondria

10.9K
Mitochondria are eukaryotic cellular organelles that are known to produce energy through a process called oxidative phosphorylation. Besides their primary function, mitochondria are involved in various cellular processes, including cell growth, differentiation, signaling, metabolism, and senescence. Age-related changes cause a decline in mitochondrial quality and integrity due to increased mitochondrial mutations and oxidative damage. Thus, aging can severely impact mitochondrial functions,...

Area of Science:

  • Reproductive biology
  • Cellular biology
  • Mitochondrial medicine

Background:

  • Successful pregnancy requires a receptive endometrium, healthy embryo, and maternal-fetal communication.
  • Pregnancy loss (PL) can occur due to flaws in these critical processes.
  • Known risk factors for PL include genetic, uterine, immune, endocrine, and environmental factors, but causes for recurrent pregnancy loss (RPL) remain unclear in over half of cases.

Purpose of the Study:

  • To comprehensively review the relationship between mitochondrial dysfunction and pregnancy loss.
  • To examine studies investigating mitochondrial dysfunction in reproductive organs and cells concerning PL.
  • To elucidate the interconnectedness of mitochondrial function and pregnancy outcomes.

Main Methods:

  • Literature review of studies on mitochondrial dysfunction and pregnancy loss.
  • Analysis of research focusing on reproductive cells and organs.
  • Synthesis of evidence linking mitochondrial factors to PL and RPL.

Main Results:

  • Accumulating evidence suggests mitochondrial dysfunction is a potential trigger for PL.
  • Studies highlight the role of mitochondria in various reproductive cells and tissues.
  • The review consolidates findings on the intricate links between mitochondrial health and pregnancy viability.

Conclusions:

  • Mitochondrial dysfunction is an emerging and significant factor in pregnancy loss.
  • Further research into mitochondrial mechanisms is crucial for understanding and potentially treating RPL.
  • Targeting mitochondrial health may offer new therapeutic avenues for improving pregnancy success.
