Review of the Bioactivities and Mechanisms of Fungus Extracts and Compounds in Colon Cancer.

Colon cancer, a malignant tumor caused by a malignant lesion of the colonic mucosal epithelium, has seen a high incidence in recent years. Fungi contain polysaccharides, terpenes, flavonoids, and other chemical components, and the diversity of these components determines the strength of a fungus's biological activity. Studies have shown that the chemical components in fungi can be used as drugs to inhibit the growth of colon cancer.

Ginsenoside Rd reduces cell proliferation of non-small cell lung cancer cells by p53-mitochondrial apoptotic pathway.

Ginsenoside Rd is a tetracyclic triterpenoid derivative, widely existing in , and other traditional Chinese medicines. Many studies have proved that ginsenoside Rd have a variety of significant biological activities on certain types of cancer. However, the mechanism of ginsenoside Rd remains unclear in lung cancer.

Ginsenoside Rb1 Inhibits the Proliferation of Lung Cancer Cells by Inducing the Mitochondrial-mediated Apoptosis Pathway.

Background: Lung cancer is one of the more common malignant tumors posing a great threat to human life, and it is very urgent to find safe and effective therapeutic drugs. The antitumor effect of ginsenosides has been reported to be a treatment with a strong effect and a high safety profile.

Objective: This paper aimed to investigate the inhibitory effect of ginsenoside Rb1 on 95D and NCI-H460 lung cancer cells and its pathway to promote apoptosis.

Review on active components and mechanism of natural product polysaccharides against gastric carcinoma.

One of the malignant tumors with a high occurrence rate worldwide is gastric carcinoma, which is an epithelial malignant tumor emerging from the stomach. Natural product polysaccharides are a kind of natural macromolecular polymers, which have the functions of regulating immunity, anti-oxidation, anti-fatigue, hypoglycemia, etc. Natural polysaccharides have remarkable effectiveness in preventing the onset, according to studies, and development of gastric cancer at both cellular and animal levels.

The enhanced role of atmospheric reduced nitrogen deposition in future over East Asia-Northwest Pacific.

The atmospheric nitrogen deposition plays a crucial role in natural ecosystem, and the changes in emissions substantially affect the amount of nitrogen deposition. Along with the decrease in NO emissions and increase in NH emissions, the reduced nitrogen deposition may play a more important role in future. However, to what extent these changes may modify the reduced nitrogen deposition across East Asia, which is fulfilled with a large amount of nitrogen deposition, to the northwestern Pacific has not yet to be clear.
