Summary
Ganoderma applanatum exo-biopolymer (EXP) demonstrated significant antitumor effects in mice. This natural compound inhibited tumor growth and boosted immune cell activity, offering potential as a cancer therapeutic.
Area of Science:
- Immunology
- Pharmacology
- Mycology
Background:
- Natural products are a rich source of potential therapeutic agents.
- Fungal exopolysaccharides (EXP) exhibit diverse biological activities.
- Ganoderma applanatum is traditionally used in medicine.
Purpose of the Study:
- To investigate the antitumor effects of Ganoderma applanatum exo-biopolymer (EXP).
- To evaluate the impact of EXP on immune cell functions in a tumor-bearing model.
Main Methods:
- Administration of EXP (10-80 mg/kg BW) to sarcoma-180 bearing mice.
- Assessment of tumor growth inhibition.
- Measurement of natural killer (NK) cell activity, complement activity, and macrophage phosphatase activity.
Main Results:
- EXP significantly inhibited solid tumor growth and increased NK cell activity.
- A dose of 40 mg/kg BW reduced tumor formation by 39.7% and increased NK cell activity by 51.6%.
- EXP enhanced complement activity and macrophage phosphatase activity in a dose-dependent manner.
Conclusions:
- Ganoderma applanatum EXP possesses significant antitumor properties.
- EXP modulates immune responses, including NK cell and macrophage activity.
- Further research into EXP as a potential anticancer agent is warranted.

Tumor Immunotherapy
Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.
Antifungal Agents
Amphotericin B is a broad-spectrum antifungal agent that exploits structural differences between fungal and mammalian cell membranes. Its amphipathic structure—featuring a hydrophobic polyene-lactone ring and a hydrophilic region containing mycosamine and carboxylic acid groups—enables selective binding to ergosterol, a sterol predominantly found in fungal plasma membranes. This selective interaction underlies the drug’s antifungal activity, although weak binding to cholesterol contributes to...
