في 2018, the 9th International Conference on Mushroom Biology and Mushroom Products was held in Shanghai. دكتور. Hua Fan from the Free University of Berlin, Germany, gave a report at the meeting and shared the result of the research conducted jointly by her laboratory and Jinsong Zhang’s Team, Institute of Edible Fungi, أكاديمية شنغهاي للعلوم الزراعية. The discussion on how a singleغانوديرما لوكيدوم polysaccharide regulates immune and anti-cancer mechanisms and the analysis on how a singleغانوديرما لوكيدوم triterpene inhibits the growth of cancer cells provide the medical potential ofغانوديرما لوكيدوم and the prospect of new drugs.

As the host of the meeting, Jinsong Zhang, the director of Institute of Edible Fungi, أكاديمية شنغهاي للعلوم الزراعية, presented a certificate to Dr. Hua Fan. The two who had a teacher-student relationship are the important drivers of bringing the traditional Chinese medicine Ganodermainto the European science hall. (تصوير / وو تينغياو)
Hua Fan, who was born in China and plantedغانوديرما لوكيدوم in the 1960s and 70s, was one of the few outstanding Chinese scientists who went to Germany to study abroad in the early days. In the early 1990s after the establishment of an immunological and anti-tumor experimental platform at the Free University of Berlin in Germany, she began to cooperate with Institute of Edible Fungi, Shanghai Academy of Agricultural Sciences to explore the bioactive components ofغانوديرما لوكيدوم and other medicinal fungi.
The graduate student who went to Germany for exchanges on behalf of Institute of Edible Fungi, Shanghai Academy of Agricultural Sciences was the main person in charge of the 9th International Conference on Mushroom Biology and Mushroom Products, Jinsong Zhang, the director of Institute of Edible Fungi; Hua Fan is the very doctoral supervisor who helped Jinsong Zhang obtain his MD degree from the Free University of Berlin, Germany.
After Jinsong Zhang returned to China, he continued to cooperate with Hua Fan’s laboratory. The polysaccharides and triterpenes in the above report were provided by Jinsong Zhang’s team at Institute of Edible Fungi. The nearly two decades of cooperation between the two parties is of great significance for the introduction of Ganoderma into the European Research hall and the promotion of global research on Ganoderma.
Polysaccharides with different structures have different immune activities.
The team isolated and purified the macromolecular polysaccharide GLIS containing 8-9% protein from the fruiting bodies ofغانوديرما لوكيدوم. Cell experiments confirmed that GLIS can activate the entire immune system through cellular immunity (activation of macrophages) and humoral immunity (activation of lymphocytes including B cells).
في الحقيقة, injecting GLIS at a dose of 100μg into each mouse pre-vaccinated with S180 sarcoma cells will increase the number of spleen cells (containing lymphocytes) by nearly one-third and inhibit tumor growth (inhibition rate reaches 60~ 70%). وهذا يعني ذلكغانوديرما لوكيدوم polysaccharide GLIS does have the ability to enhance the immune system’s ability to fight tumors.
Interestingly, another pure polysaccharide, GLPss58, which is isolated fromغانوديرما لوكيدوم الجسم المثمر, is sulfated and contains no protein components, not only does not promote immunity like GLIS but also can inhibit the proliferation and activity of macrophages and lymphocytes, reduce the production of inflammatory cytokines, and prevent lymphocytes in the blood from migrating to the inflamed tissues… Its multiple mechanisms reduce the intensity of the immune response. This effect is just suitable for the medical needs of patients with chronic excessive inflammation (such as lupus erythematosus and other autoimmune diseases).
The anti-cancer mechanism of triterpenoids is different from that of polysaccharides.
فضلاً عن ذلك, Hua Fan’s team also evaluated the anticancer activity of eight single triterpene compounds in the fruiting body ofغانوديرما لوكيدوم. The results showed that two of these triterpenes have significant antiproliferative and pro-apoptotic effects on human breast cancer cells, human colorectal cancer cells and malignant melanoma cells.
In further analysis of the mechanisms by which these two triterpenes promote apoptosis of cancer cells, the researchers found that they “directly” force cancer cells to self-destruct through “reducing the membrane potential of mitochondria” and “increasing the oxidative pressure of mitochondria”. This is completely different from the role ofغانوديرما لوكيدوم polysaccharide GLIS that “indirectly” inhibits tumors through the immune system.
Polysaccharides or triterpenes can be used singly or in combination.
Hua Fan made us understand through the rigorous German research model that the various active ingredients inغانوديرما لوكيدوم can be “combined” to create the health value of prolonging life or can be “applied separately” to provide specific curative effects for existing diseases.
Is it possible to make the active polysaccharides and active triterpenes in the experiment into clinical drugs in the future? “Then look at the younger generation!” Hua Fan looked expectantly at Jinsong Zhang, who had already established a strong research team.
