The in vitro and in vivo experimental evidences disclose the chemopreventive effects of Ganoderma lucidum on cancer invasion and metastasis

Abstract

The Ganoderma lucidum (Leyss. ex Fr.) Karst, an edible mushroom, has been utilized for centuries in East Asia to prevent or treat various diseases and to reduce the likelihood of cancer invasion and metastasis. The primary bioactive compounds are commonly considered to be polysaccharides and triterpenoids. Evidence that G. lucidum extract and its bioactive compounds may have a potential inhibitory effect on cancer invasion and metastasis is increasingly being reported in the scientific literature. This review assembles and summarizes past publications on the in vitro and in vivo effects of G. lucidum on cancer invasion and metastasis, and concludes that these effects occur through modulation of the phosphorylation of extracellular signal-regulated kinase (ERK1/2), phosphatidylinositol 3-kinase (PI 3-kinase) or Akt kinase (protein kinase B). Activation of these kinases subsequently inhibits the activity or expression of activator protein-1(AP-1) and nuclear factor-kappa B (NF-kappaB), resulting in the down-regulation of urokinase plaminogen activator (uPA), uPA receptor (uPAR), matrix metalloproteinase (MMP)-9, vascular endothelial growth factor (VEGF), transforming growth factor (TGF)-beta1, interleukin (IL)-8, inducible nitric oxide (NO) and beta1-integrin as shown in various cell lines or animal models. G. lucidum may be an effective nutraceutical used in the prevention of cancer metastasis. To further elucidate the bioactive components present in G. lucidum and the anti-metastatic mechanisms underlying these compounds, more in vitro and in vivo tests as well as clinical trials are necessary.

Cantharidin Impairs Cell Migration and Invasion of Human Lung Cancer NCI-H460 Cells via UPA and MAPK Signaling Pathways

“…It is well known that cancer cells are of high invasion and migration ability leading to metastasis that proceeds through a complex multistep process involving cell adhesion, proteolysis degradation of extracellular matrix (ECM), angiogenesis and invasion (34). Thus, several studies and development of new anticancer drugs are revolving around anti-metastasis research (35).…”

Multiple Molecular Targets of Antrodia camphorata: A Suitable Candidate for Breast Cancer Chemoprevention

“…Therefore, chemotherapy is suggested to prevent local recurrence of the primary tumor and the spread of tumor cells (Weng & Yen, 2010). However, commercially available synthetic chemotherapeutic agents have severe side effects.…”

“…Tumor growth and metastasis is angiogenesis dependent. Several lines of direct evidence have shown that angiogenesis is essential for tumor growth and metastasis (Weng & Yen, 2010). The ex vivo check chorioallatonic membrane (CAM) assay is commonly employed to examine the anti-angiogenic activity of samples.…”

Matrix metalloproteinase-9 gene polymorphism in hepatocellular carcinoma patients with hepatitis B and C viruses

“…Matrix metalloproteinase (MMPs) are a family of zinc-dependent extracellular endopeptidase enzymes that play a vital role in the proteolysis of structural and signaling components of the extracellular matrix (ECM) and influence cell differentiation, migration, invasion, and proliferations of cells (Weng and Yen, 2010). Since HCC tumors develop in fibrotic livers, MMP activity is particularly necessary for growth, invasion and metastasis.…”
