Ganoderma lucidum is actually a popular herbal medicine found in China to promote health. Modern reports have disclosed that the active ingredients of Ganoderma can exhibit a number of effects, including antitumor effects and immunomodulation. The present study evaluated the antitumor outcomes of self-prepared ganoderma lucidum spore oil and spores oil, and investigated the possible underlying mechanisms by observing the consequences of the extracts and oil on topoisomerases and also the cell cycle. The outcomes indicated that Ganoderma extracts and spores oil presented dose-dependent inhibitory effects on tumor cells.

Ganoderma lucidum, also called Ganoderma or Lingzhi, is one of most regularly used fungi in Chinese medicine. Modern pharmacological and clinical tests have confirmed that Ganoderma contains abundant biologically active substances in their fruiting body, mycelia and spores, and possesses variable functions, including immunomodulation, anti-aging, reducing blood lipids, anti-viral and anti-tumor activities (1-6). The present study examined the antitumor activity of a blend of aqueous and ethanol extracts in the Ganoderma fruiting body and Ganoderma Spores Oil, which was extracted from broken spores by supercritical CO2 extraction technology and explored the possible underlying mechanisms. DNA topoisomerases certainly are a class of enzymes active in the regulating DNA supercoiling.

Topoisomerase overexpression has been connected to numerous human malignancies and it is the prospective for numerous chemotherapeutic agents (7). When topoisomerases are blocked, the cell encounters problems during transcription in the DNA and throughout cell division. The widely-used antitumor drug, campothecin, blocks the relaxing action of class I topoisomerases and induces significant G1 cell cycle arrest (8). A previous study indicated that the active aspects of Ganoderma exhibited inhibition of topoisomerases (9). The present study examined whether Ganoderma extracts and spore oil affected the cell cycle and topoisomerases I and II.

Preparations of Ganoderma extracts and spores oil – Ganoderma extracts (GanoHerb) and Ganoderma spores oil were offered by Fujian Xianzhilou Biological Science and Technology Co., Ltd. (Fuzhou, China). Ganoderma extract, a brown powder, was dissolved in double distilled water to prepare solutions of numerous concentrations, that were brown suspensions. Ganoderma spores oil was a soft capsule with .5 g/.5 ml golden oil in each capsule. The stock solution of Agaricus Blazei Extract were prepared using double distilled water that contained 6 µl/ml (v/v) Tween 80.

Recently, the result of Ganoderma on tumors continues to be increasingly studied. The present study revealed that Ganoderma extracts and spores oil inhibited the development of human leukemia cells (K562 and HL60) and human gastric carcinoma cells (SGC-7901) in a dose-dependent manner. In addition, Ganoderma extracts and spores significantly suppressed the growth of the S180 and H22 transplant tumors in mice. Therefore, Ganoderma extracts and spores oil demonstrated definite antitumor effects within the in vitro vrlzqn in vivo studies.

Since ancient times, Ganoderma has been widely used being a popular herbal medicine for that promotion of health (11). Numerous previous studies examined the immunomodulatory activities of Ganoderma (12,13). By detecting the immunity indexes of mice bearing S180 or H22 cells, Ganoderma extracts were concluded to get a certain effect on improving immune function, while Ganoderma spores oil had no significant effect on the spleen or thymus indexes of mice. One of many components of Ganoderma extract is actually a polysaccharide which has been reported as immune function enhancer (12-15). As there were few polysaccharides (water-soluble substances) in the Ganoderma spores oil, the spores oil exhibited no evident impact on immunity. The present study also established that the antitumor effects of Ganoderma may be safer compared with 5-FU, which ended in the decreased weight and immunity indexes of mice (Tables I and ?andIIII).

To investigate the possible mechanism of Agaricus Blazei Extract, the results of extracts and spores oil on topoisomerases and the effect of spores oil on the cell cycle were examined.

DNA topoisomerases really are a class of enzymes working in the regulation of DNA supercoiling. Type I topoisomerases alter the amount of supercoiling of DNA by causing single-strand breaks and religation, whereas type II topoisomerases cause double-strand breaks. Those two activities are particularly crucial during DNA transcription and replication, if the DNA helix must be unwound to allow proper function of large enzymatic machinery. Cancer chemotherapy takes advantage of this finding, using drugs that block topoisomerases to kill rapidly-dividing cancer cells. For example, the widely-used anthracycline drugs, like doxorubicin and daunorubicin, attack class II topoisomerases and also the plant toxin, campothecin, blocks the relaxing action of class I topoisomerases.
