Mushroom-derived preparations in the prevention of H2O2-induced oxidative damage to cellular DNA

Area of Science:

• Mycology
• Biochemistry
• Genetics

Background:

• Oxidative stress can damage cellular DNA, contributing to various health issues.
• Edible mushrooms are known for their rich nutritional and bioactive compound profiles.
• Identifying natural sources of compounds that protect DNA is crucial for health and wellness.

Purpose of the Study:

• To evaluate the genoprotective potential of aqueous extracts from eight mushroom species against hydrogen peroxide (H2O2)-induced DNA damage.
• To identify specific mushroom species that exhibit significant DNA protection capabilities.

Main Methods:

• Aqueous extracts were prepared from the sporophores of eight mushroom species using cold (20°C) and hot (100°C) water.
• The single-cell gel electrophoresis (Comet assay) was employed to assess the ability of these extracts to protect cellular DNA from H2O2-induced damage.
• Mushroom Derived Preparations (MDPs) were tested for their genoprotective activity.

Main Results:

• Cold and hot water extracts of *Agaricus bisporus* and *Ganoderma lucidum* fruit bodies demonstrated the highest genoprotective effects.
• Extracts from *Flammulina velutipes*, *Auricularia auricula*, *Hypsizygus marmoreus*, *Lentinula edodes*, *Pleurotus sajor-caju*, and *Volvariella volvacea* showed no significant protective effects.
• The efficacy of genoprotection varied depending on the mushroom species and extraction temperature.

Conclusions:

• *Agaricus bisporus* and *Ganoderma lucidum* are valuable sources of compounds that can protect cellular DNA from oxidative damage.
• These findings highlight the potential of specific edible mushrooms in developing natural agents for DNA protection.
• Further research is warranted to isolate and characterize the specific bioactive compounds responsible for the observed genoprotective effects.
