Insights

Antifungal drug resistance in invasive fungal infections is a major challenge. Genome sequencing reveals resistance evolves through various genetic changes, not just single gene mutations, offering new insights for treatment.

Area of Science:

  • Medical Mycology
  • Genomics
  • Antimicrobial Resistance

Background:

  • Invasive fungal infections have high mortality rates due to limited antifungal drugs and evolving resistance.
  • Antifungal drug resistance is a significant clinical challenge, necessitating a deeper understanding of its evolutionary mechanisms.

Purpose of the Study:

  • To review mutations selected during the adaptive microevolution of antifungal drug resistance.
  • To highlight how advances in genome sequencing have improved understanding of antifungal resistance evolution.

Main Methods:

  • Review of existing literature on antifungal drug resistance.
  • Analysis of findings from whole genome sequencing studies in fungal isolates.
  • Examination of genetic mutations and aneuploidy associated with resistance.

Main Results:

  • Antifungal resistance can emerge through ERG11-independent mechanisms.
  • Polygenic resistance phenotypes arise from accumulated mutations in multiple genes.
  • Aneuploidy (full or partial) is a common mechanism conferring antifungal resistance in clinical and in vitro isolates.

Conclusions:

  • Antifungal resistance evolution is more complex than previously thought, involving multiple genetic pathways.
  • Genome sequencing technologies are crucial for uncovering the diverse mechanisms of antifungal resistance.
  • Understanding these microevolutionary processes is key to developing effective antifungal therapies.

Treatment Resistant Cancers02:56

Treatment Resistant Cancers

Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...

Defense Against Bacterial Pathogens01:31

Defense Against Bacterial Pathogens

The human immune system is a complex network of cells, tissues, and organs that work together to defend the body against bacterial infections. It consists of various immune cells, each playing a specific role in the defense mechanism.
Phagocytes
Phagocytes are the frontline soldiers of the immune system. They include neutrophils and macrophages. Neutrophils are the most abundant type of white blood cell and are quickly mobilized to the site of infection. Macrophages are larger cells that patrol...

Viral Mutations00:36

Viral Mutations

A mutation is a change in the sequence of bases of DNA or RNA in a genome. Some mutations occur during replication of the genome due to errors made by the polymerase enzymes that replicate DNA or RNA. Unlike DNA polymerase, RNA polymerase is prone to errors because it is not capable of “proofreading” its work. Viruses with RNA-based genomes, like HIV, therefore accrue mutations faster than viruses with DNA-based genomes. Because mutation and recombination provide the raw material...

Genome Size and the Evolution of New Genes03:21

Genome Size and the Evolution of New Genes

While every living organism has a genome of some kind (be it RNA, or DNA), there is considerable variation in the sizes of these blueprints. One major factor that impacts genome size is whether the organism is prokaryotic or eukaryotic. In prokaryotes, the genome contains little to no non-coding sequence, such that genes are tightly clustered in groups or operons sequentially along the chromosome. Conversely, the genes in eukaryotes are punctuated by long stretches of non-coding sequence.
