Potential growth inhibitory effect of maitake D-fraction on canine cancer cells
1Department of Urology, New York Medical College, Munger Pavilion 4th Floor, Valhalla, NY, 10595, USA.
Abstract:
The postulated anticancer effect of D-fraction, the bioactive extract of maitake mushroom, on three types (CF33, CF21, and CL-1) of canine cancer cells was evaluated. The effect of D-fraction on several human cancer cells was also investigated. The effect of other beta-glucan products was likewise examined. D-fraction was highly effective on the canine cancer cells, either potently inhibiting cell growth or directly killing cells. Similar effects were also demonstrated in certain human cancer cells. However, other beta-glucan products relevant to D-fraction had no such effects on canine cancer cells. Therefore, D-fraction is a potent natural agent that could be useful in treating canine cancers as well as other veterinary cancers.
Insights
Maitake mushroom
Area of Science:
- Veterinary Oncology
- Natural Product Chemistry
Background:
- Maitake mushroom (Grifola frondosa) contains bioactive compounds.
- Beta-glucans are known for their immunomodulatory properties.
- D-fraction is a specific beta-glucan extract from maitake.
Purpose of the Study:
- To evaluate the anticancer effects of D-fraction on canine cancer cells.
- To compare D-fraction's efficacy with other beta-glucan products.
- To investigate D-fraction's potential in veterinary cancer treatment.
Main Methods:
- In vitro evaluation of D-fraction on canine cancer cell lines (CF33, CF21, CL-1).
- Assessment of D-fraction's impact on human cancer cells.
- Comparative analysis with other beta-glucan products.
Main Results:
- D-fraction demonstrated significant anticancer activity against canine cancer cells.
- D-fraction inhibited cell growth and induced cell death in canine cancer models.
- Similar potent effects were observed in certain human cancer cell lines.
- Other beta-glucan products showed no comparable effects on canine cancer cells.
Conclusions:
- D-fraction is a potent natural agent with significant anticancer properties.
- D-fraction shows promise for treating canine and other veterinary cancers.
- Its efficacy distinguishes it from other beta-glucan products in veterinary oncology.
