Animal Mitochondrial Genetics02:59

Animal Mitochondrial Genetics

9.2K
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...

Comparing Mitochondrial, Chloroplast, and Prokaryotic Genomes

16.0K
The present-day mitochondrial and chloroplast genomes have retained some of the characteristics of their ancestral prokaryotes and also have acquired new attributes during their evolution within eukaryotic cells. Like prokaryotic genomes, mitochondrial and chloroplast genomes neither bind with histone-like proteins nor show complex packaging into chromosome-like structures, as observed in eukaryotes. Unlike mitotic cell divisions observed in eukaryotic cells, mitochondria and chloroplasts...

Export of Mitochondrial and Chloroplast Genes02:19

Export of Mitochondrial and Chloroplast Genes

4.2K
A eukaryotic cell can have up to three different types of genetic systems: nuclear, mitochondrial, and chloroplast. During evolution, organelles have exported many genes to the nucleus; this transfer is still ongoing in some plant species. Approximately 18% of the Arabidopsis thaliana nuclear genome is thought to be derived from the chloroplast’s cyanobacterial ancestor, and around 75% of the yeast genome derived from the mitochondria’s bacterial ancestor. This export has occurred...

The Inner Mitochondrial Membrane01:28

The Inner Mitochondrial Membrane

4.7K
The inner mitochondrial membrane is the primary site of ATP synthesis. The inner membrane domain that forms a smooth layer adjacent to the outer membrane is called the inner boundary membrane. This domain contains membrane transporters that drive metabolites in and out of the mitochondria.  In contrast, the inner membrane network that invaginates into the matrix space is called the cristae membrane. This domain accounts for principle mitochondrial function as it accommodates the protein...

Dynamic Equilibrium02:20

Dynamic Equilibrium

62.6K
A reversible chemical reaction represents a chemical process that proceeds in both forward (left to right) and reverse (right to left) directions. When the rates of the forward and reverse reactions are equal, the concentrations of the reactant and product species remain constant over time and the system is at equilibrium. A special double arrow is used to emphasize the reversible nature of the reaction. The relative concentrations of reactants and products in equilibrium systems vary greatly;...

Mitochondrial Membranes01:45

Mitochondrial Membranes

17.1K
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,...

Area of Science:

  • Cellular Biology
  • Microbiology
  • Immunology

Background:

  • Mitochondria are dynamic organelles crucial for energy production, calcium metabolism, and apoptosis.
  • Mitochondria also play a key role in innate immune responses.
  • Mitochondrial dynamics, including division, fusion, and motility, maintain organelle structure and function.

Purpose of the Study:

  • To investigate how microbes subvert mitochondrial function during infection.
  • To understand the role of mitochondrial dynamics in pathogen-host interactions.
  • To elucidate how pathogens exploit mitochondrial alterations to promote disease.

Main Methods:

  • Review of existing literature on microbe-mitochondria interactions.
  • Analysis of how pathogen infection impacts mitochondrial bioenergetics and dynamics.
  • Examination of the benefits pathogens gain by manipulating mitochondrial shaping and function.

Main Results:

  • Pathogens actively manipulate mitochondrial bioenergetics and dynamics to their advantage.
  • Altered mitochondrial structure and function are observed during microbe infections.
  • Microbial manipulation of mitochondria aids in evading host defenses and disease progression.

Conclusions:

  • Mitochondria are critical targets for microbial manipulation.
  • Pathogens exploit mitochondrial dynamics to escape host control and establish infection.
  • Understanding these interactions is key to developing new therapeutic strategies against infectious diseases.
