Hispolon is a polyphenolic compound isolated from Phellinus linteus which exhibits antitumor activity. Here, we explored the effects of hispolon on human glioblastoma cells U87MG. Cell viability was examined by MTT assay. Growth was investigated by incubating cells with various concentrations of hispolon (25 and 50 mM) for 24, 48 or 72 h and daily cell count. Cell cycle and apoptosis assay were assessed by flow cytometry. Hispolon decreased cell viability in a dose- and timedependent manner. The cell cycle distribution showed that hispolon enhanced the...

Abstract Severe side effects from chemotherapy or immunotherapy often limit their clinical utility in urothelial cell carcinoma of the bladder. To explore alternative therapies, we were particularly interested in one of medicinal mushrooms called Phellinus linteus (PL) with antitumor/anticancer activity. We investigated possible anticancer effects of three distinct extracts or fractions of PL using an urothelial cell carcinoma (UCC) model in vitro. Those fractions included PL-I (crude extract), PL-II (water-extracted), and PL-III (ethanol-extracted), which were tested for...

Phellinus linteus, a species of mushroom, has been shown to contribute to health benefits, such as anti-inflammatory activity and immunomodulatory efficacy. The aim of this study was to analyze the most effective constituents of P. linteus fermented broths, polysaccharides, and to evaluate their immunoregulatory effects on T cells. Four fermented broths (PL1e4) and the dialyzate medium (MD) were prepared from P. linteus mycelia, and the polysaccharide contents of each were analyzed. The P. linteus samples were tested for biological activity in the regulation of T cell...

Abstract Background: Although several therapeutic options are currently available for patients with various cancers, the outcomes are often disappointing and a more effective modality needs to be promptly established. We have been exploring an alternative approach using natural agents and two bioactive mushroom extracts isolated from Phellinus linteus (PL), namely PL-ES and PL-I-ES, were of our interest.  As anticancer effects of similar extracts have been reported in several cancers, we investigated whether PL-ES and PL-I-ES might have such anticancer activities on...

Abstract: Hispolon is one of the most important functional compounds that forms Phellinus linteus (Berkeley & Curtis) Teng. Hispolon has antioxidant, anti-inflammatory, antiproliferative and anticancer effects. In this study, we analyzed the functions of hispolon on melanogenesis and apoptosis in B16-F10 melanoma cells. The results demonstrated that hispolon is not an enzymatic inhibitor for tyrosinase; rather, it represses the expression of tyrosinase and the microphthalmia-associated transcription factor (MITF) to reduce the production of melanin in...

Pancreatic cancer (ductal adenocarcinoma) is one of the most lethal malignancies in gastrointestinal system. Till now, only margin-negative pancreatectomy is known to be the best treatment option for long-term survival. However, the resection rate is reported to be less than 20%. Even in cases of curative resection, most patients generally experience disease recurrence and ultimately die of metastatic disease. Therefore, surgery alone is not enough and adjuvant systemic chemotherapy should be considered for proper management of pancreatic cancer. But, its...
