Aberrant activation of Wnt/β-catenin signaling plays an important role in the development of colon cancer. HS7 is an active fraction extracted from Taiwanofungus camphoratus, which had been widely used as complementary medicine for Taiwan cancer patients in the past decades. In this study, we demonstrated the effects of HS7 on the growth inhibition, apoptosis induction, and Wnt/β-catenin signaling suppression in human colon cancer cells. HS7 significantly inhibited proliferation of HT29, HCT116, and SW480 colon cancer cells in a dose- and time-dependent manner. The apoptosis induction was evidenced by DNA fragmentation and subG1 accumulation, which was associated with increased Bax/Bcl-2 ratio, activation of caspase-3 and cleavage of PARP. By using Tcf-dependent luciferase activity assay, HS7 was found to inhibit the β-catenin/Tcf transcriptional activities. In addition, HS7 strongly suppressed the binding of Tcf complexes to its DNA-binding site shown in electrophoretic mobility shift assay. This inhibition was further confirmed by the decreased protein levels of Tcf-4 and β-catenin. The β-catenin/Tcf downstream target genes, such as survivin, c-myc, cyclin D1, MMP7,andMT1-MMP involved in apoptosis, invasion, and angiogenesis were also diminished as well. These results indicate that Taiwanofungus camphoratus may provide a benefit as integrative medicine for the treatment of colon cancer. 1. Introduction cancer therapy.

ITS (internal transcribed spacer) sequences were obtained from each specimen to confirm the determinations. Key words—aphyllophoroid fungi, fungal biodiversity, DNA barcoding, fungal cultures, ITS rDNA Introduction Polypores are a large group of Basidiomycota with poroid hymenophores on the underside of fruiting bodies, which may be pileate, resupinate, or effused-reflexed, and with textures that are typically corky, leathery, tough, or even woody hard (Härkönen & al. 2015). Formerly, polypores were treated mostly in Polyporaceae Corda s.l. (under Polyporales) and Hymenochaetaceae Imazeki & Toki s.l. (under Hymenochaetales), with some species in Corticiaceae Herter s.l. (Gilbertson & Ryvarden 1986, 1987; Ryvarden & Melo 2014). However, modern DNA-based phylogenetic studies distribute polyporoid genera across at least 12 orders of Agaricomycetes Doweld, e.g., Polyporales Gäum., Hymenochaetales Oberw., Russulales Kreisel ex P.M.

Most polypores are wood-rotters that decompose the cellulose, hemicellulose, or lignin of woody biomass in forests; these fungi are either saprobes on trees, stumps, and fallen branches or parasites on living tree trunks or roots and therefore play a crucial role in nutrient recycling for the earth (Härkönen & al.

  • Finding of a Novel Fungal Immunomodulatory Protein Coding
    ARTÍCULO DE INVESTIGACIÓN Finding of a novel fungal immunomodulatory protein coding sequence in Ganoderma australe Hallazgo de una nueva secuencia codificadora para una proteína inmunomoduladora de origen fúngico en Ganoderma australe Andrea González Muñoz*, Kelly Johana Botero Orozco**, Germán Ariel López Gartner*** Abstract Among the most common human diseases with immune system compromise are autoimmune diseases, cancer, and the acquired immunodeficiency syndrome (AIDS). Many of these diseases still have no treatment or their therapies have un- desirable side effects. This has aroused a great interest in the search for new natural products with therapeutic potential and scientifically proven effects, showing minimal side effects. Formal clinical and pharmacological investigation in various medicinal fungi of the genus Ganoderma (Ganodermataceae) has shown immunomodulatory effects and tumor growth inhibition in mammals, attributable to the presence of immunomodulatory proteins and other secondary metabolites. To date, six fungal immunomodulatory proteins (FIPs) have been reported in Ganoderma. This paper seeks to advance in the discovery of immunomodulatory proteins present in Ganoderma australe, through mycelium transcriptome 454 Roche® pyrosequencing (RNA-seq) and bioinformatics analyses. The results suggest the presence of gene sequences related to an immunomodulatory protein which has been reported in another fungal species Taiwanofungus camphoratus. The candidate gene sequences found in G. australe exhibit high identity values in their amino acid composition and predicted protein secondary structure with the protein reported for Tai. camphoratus. According to present knowledge about the action mechanisms of these proteins, it is possible to suggest that this is a promising molecule for the treatment and prevention of diseases associated with certain immune deficiencies, cancer, and other diseases with compromised immune systems.

In this article, a brief overview is given of the most important medical mushroom species and their specific anti-cancer functions and mechanisms. Taiwanofungus camphoratus (Antrodia cinnamomea), is a medical fungus chosen to examine the process from ethnomedicine to developing new products for the market based on scientific, analytic, and experimental evidence. The bioactive compounds have indirect effects in cancer treatment by benefiting the immune system as well as having direct cytotoxic effects on cancer cells. Taiwanofungus camphoratus is a fungus endemic to Taiwan and one of the most popular known alternative remedies for liver cancer in Taiwan. To date, more than 150 liver cancer patients have survived using T.

Antrodia camphorata is a unique mushroom of Taiwan, which has been used as a traditional medicine for protection of diverse health-related conditions. In an effort to translate this Eastern medicine into Western-accepted therapy, a great deal of work has been carried out on A. camphorata. This review discusses the biological activities of the crude extracts and the main bioactive compounds of A. camphorata. The list of bioactivities of crude extracts is huge, ranging from anti-cancer to vasorelaxation and others. Over 78 compounds consisting of terpenoids, benzenoids, lignans, benzoquinone derivatives, succinic and maleic derivatives, in addition to polysaccharides have been identified. Many of these compounds were evaluated for biological activity. Many activities of crude extracts and pure compounds of A. camphorata against some major diseases of our time, and thus, a current review is of great importance. It is concluded that A. camphorata can be considered as an efficient alternative phytotherapeutic agent or a synergizer in the treatment of cancer and other immune-related diseases.
