Abstract:
Agaricus blazei Murrill extracts have previously been shown to have anticarcinogenic and antimutagenic properties. These results suggest that antimutagenic activity, besides the modulation of the immune system, might be involved in the anticarcinogenic action of A. blazei. To investigate the possible antimutagenic effect of A. blazei in vivo, we evaluated its effect on clastogenicity induced by cyclophosphamide (CP) in mice, using the micronucleus test in bone marrow (MNPCE) and in peripheral blood (MNRET). Male Swiss mice were treated with CP (25 or 50mg/kg i.p.) or with CP plus mushroom solution at three different temperatures: 4, 21, and 60 degrees C. Aqueous solution of a mixture from various lineages of the mushroom inhibited induction of micronuclei by CP in bone marrow and in peripheral blood of mice. In contrast to the mixture of lineages, a single isolated lineage did not lead to a reduction of CP-induced MN frequencies in either bone marrow or blood cells of mice. The results suggest that under certain circumstances these mushrooms exhibit antimutagenic activities that might contribute to an anticarcinogenic effect.
Insights
Agaricus blazei Murrill mushroom extracts demonstrated antimutagenic properties in vivo. A mixture of mushroom lineages inhibited cyclophosphamide-induced micronuclei formation in mice, suggesting a role in cancer prevention.
Area of Science:
- Mycology
- Toxicology
- Immunology
Background:
- Agaricus blazei Murrill extracts show anticarcinogenic and antimutagenic potential.
- Antimutagenic activity may contribute to the anticarcinogenic effects of A. blazei, alongside immune system modulation.
Purpose of the Study:
- To investigate the in vivo antimutagenic effect of A. blazei.
- To evaluate the impact of A. blazei on cyclophosphamide (CP)-induced clastogenicity in mice.
Main Methods:
- Male Swiss mice were treated with cyclophosphamide (CP) alone or with CP plus A. blazei mushroom solution at varying temperatures (4, 21, 60°C).
- The micronucleus test in bone marrow (MNPCE) and peripheral blood (MNRET) was used to assess clastogenicity.
Main Results:
- An aqueous solution of a mixture of A. blazei lineages inhibited CP-induced micronuclei formation in both bone marrow and peripheral blood.
- A single isolated lineage of A. blazei did not reduce CP-induced micronuclei frequencies.
Conclusions:
- A. blazei exhibits in vivo antimutagenic activity, particularly when using a mixture of lineages.
- This antimutagenic effect may contribute to the observed anticarcinogenic properties of A. blazei under specific conditions.
