Betaglucan triterpen (Reishi mushroom) protects radiation induced DNA damage

In radiation therapy, healthy cells need to be protected when cancer cells are exposed to high concentrations of radioactive material. A significant number of natural and synthetic substances have been evaluated for that purpose but have been largely unsuccessful in clinical terms due to side effects and toxicity. Therefore, it is urgent to find a substance that protects cells from the harmful effects of radioactive substances without side effects. Fortunately, the creator always has its own way and that is why we have Ganoderma lucidum that can take on that role. There have been many studies in the world conducted on two active ingredients betaglucan, triterpen- Ganoderma lucidum to demonstrate the ability to protect DNA with the following recommended mechanisms:

Betaglucan protects DNA from high concentrations of radiation.

Betaglucan in medicinal mushrooms in general and Ganoderma lucidum in particular has the remarkable ability to protect human lymphocyte DNA from radiation damage thanks to its DNA repair ability and antioxidant activity.
Betaglucan is highly effective in reducing anomalies in chromosome structure helping to protect against single and double strand breaks in chromosomes, in addition to can enhance DNA repair in human lymphocytes . Polysaccharides in fungi prevent cancer formation, have antitumor activity, directly against various heterogeneous and synthetic tumors, in addition prevent tumor metastasis.

Triterpenoids from Ganoderma lucidum help prevent cell membrane and DNA damage caused by gamma radiation.

Cell membranes and DNA are important targets for radiation-induced inactivation in biological systems. The interaction of ionizing radiation with biological systems leads to the generation of free radicals. When these free radicals are produced, the body naturally has a defense against them thanks to a system of endogenous antioxidant enzymes. However, if the amount of free radicals produced is too large, the antioxidant enzyme system overloads not enough to block all free radicals, and then the free radicals will cause membrane fat oxidation. this leads to destruction of the membrane structure and inactivation of membrane-binding enzymes. In particular, the membranes surrounding cells and organelles such as mitochondria, lysosomes and peroxisomes are more susceptible to attack because they contain a large number of polyunsaturated fatty acid (PUFA) chains – a type of fat. Very susceptible to oxidation. PUFA oxidation tends to decrease membrane fluidity, which is considered essential for the normal functioning of biofilms.

Fracture of single and double strands as well as changes in the base and sugar composition of the chromosome structure are often observed in cells exposed to ionizing radiation. Double-strand breaks are particularly important events in radiation-induced cell damage. Extracts containing triterpenes from Ganoderma lucidum are highly effective in protecting single-stranded, radiation-induced fractures in rats’ plasmid pBR 322 DNA, even at very low concentrations. Chromosomal abnormalities are a direct consequence and manifestation of damage at the DNA level – for example, a chromosomal rupture can be caused by an unrepaired double-strand break in the DNA and placement. Re-chromosome can be caused by false correction.
Triterpens total extract from Ganoderma lucidum has been studied to prevent damage to cell membranes and radiation caused by radiation in mouse mitochondria and liver microsomes. Potential in protecting cells from radiation damage. Another in vitro study showed that reishi mushroom Triterpens extract prevents DNA damage caused by radiation and apoptosis in spleen lymphocytes.

Although radiotherapy is a popular and effective method of cancer treatment, the effect on normal cells, especially those adjacent to the tumor, limits the effectiveness of treatment. . Hence, the protection of normal tissues against cell damage is of great importance in radiotherapy. Medicinal mushrooms, namely the active ingredient Betaglucan Triterpen extract from Ganoderma lucidum mushrooms are considered the most highly regarded candidate for their ability to protect cells from radiation damage by their safety and content. Biologically active.
Betaglucan Triterpen is a unique and best product available today that protects cell membranes and protects DNA from damage caused by radiation.
