Genomic DNA in Prokaryotes00:46

Genomic DNA in Prokaryotes

The genome of most prokaryotic organisms consists of double-stranded DNA organized into one circular chromosome in a region of cytoplasm called the nucleoid. The chromosome is tightly wound, or supercoiled, for efficient storage. Prokaryotes also contain other circular pieces of DNA called plasmids. These plasmids are smaller than the chromosome and often carry genes that confer adaptive functions, such as antibiotic resistance.

Bacterial Transformation01:33

Bacterial Transformation

In 1928, bacteriologist Frederick Griffith worked on a vaccine for pneumonia, which is caused by Streptococcus pneumoniae bacteria. Griffith studied two pneumonia strains in mice: one pathogenic and one non-pathogenic. Only the pathogenic strain killed host mice.
Griffith made an unexpected discovery when he killed the pathogenic strain and mixed its remains with the live, non-pathogenic strain. Not only did the mixture kill host mice, but it also contained living pathogenic bacteria that...
Coordination of Gene Expression Processes in Bacteria01:29

Coordination of Gene Expression Processes in Bacteria

The DNA replication, transcription, and translation processes are intricately coupled in bacteria, allowing efficient gene expression and rapid protein synthesis. While this physical and functional coordination is advantageous, it introduces challenges that bacteria overcome through specific regulatory mechanisms.Coupling of Replication, Transcription, and TranslationThe coupling of replication, transcription, and translation is a hallmark of bacterial gene expression. As the replisome unwinds...
Epigenetic Regulation01:46

Epigenetic Regulation

Epigenetic mechanisms play an essential role in healthy development. Conversely, precisely regulated epigenetic mechanisms are disrupted in diseases like cancer.
Epigenetic Regulation01:37

Epigenetic Regulation

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.

Gene Regulation in Microbial Communities: Quorum Sensing01:28

Gene Regulation in Microbial Communities: Quorum Sensing

Quorum sensing is a mechanism of bacterial communication that enables coordinated gene expression in response to changes in population density. This facilitates collective behaviors that enhance survival, resource acquisition, and ecological adaptation. This process relies on small signaling molecules called autoinducers that accumulate as bacterial populations grow. When a critical threshold concentration of autoinducers is reached, bacterial cells collectively modify gene expression,...

Area of Science:

  • Molecular Biology
  • Microbiology
  • Epigenetics

Background:

  • Epigenetic mechanisms control genome expression for cell differentiation and response to stimuli.
  • Bacteria can influence host cell chromatin structure and transcription via epigenetic factors.
  • Epigenetic factors include histone modifications, DNA methylation, and noncoding RNAs.

Purpose of the Study:

  • To review the molecular basis of epigenetic language.
  • To describe how bacteria alter host epigenetic marks and machinery.
  • To discuss the implications of bacterial-induced epigenetic changes.

Main Methods:

  • Literature review of epigenetic mechanisms.
  • Analysis of current research on bacteria-host epigenetic interactions.
  • Discussion of pathogenic bacteria as epimutagens.

Main Results:

  • Bacteria influence host epigenetics through various factors like histone modifications and DNA methylation.
  • Bacterial-induced epigenetic changes can promote host defense or pathogen persistence.
  • Pathogenic bacteria can act as epimutagens, reshaping the host epigenome.

Conclusions:

  • Bacterial interactions with host epigenetics can lead to long-lasting cellular imprints.
  • These epigenetic changes may influence host immunity and create an infection memory.
  • Bacterial epimutations might underlie certain unexplained diseases.
