Cordyceps militaris (CM) and its active ingredient cordycepin have been reported to inhibit tumor growth, but the mechanisms are not fully understood. This study used a mouse model for oral cancer and a cell line, 4NAOC-1 derived from the model to study the mechanisms. Our results show that a CM preparation (CMP) can significantly inhibit tumor development and malignant transformation in the model. In vitro data indicate that CMP and cordycepin can inhibit 4NAOC-1 cell proliferation, either anchorage-dependent or -independent...

Lung cancer is the leading cause of cancer deaths worldwide, and this makes it an attractive disease to review and possibly improve therapeutic treatment options. Surgery, radiation, chemotherapy, targeted treatments, and immunotherapy separate or in combination are commonly used to treat lung cancer. However, these treatment types may cause different side effects, and chemotherapy-based regimens appear to have reached a therapeutic plateau. Hence, effective, better-tolerated treatments are needed to address and hopefully overcome this conundrum...

Cordyceps militaris produces cordycepin, which is known to be a bioactive compound. Currently, cordycepin hyperproduction of C. militaris was carried out in a liquid surface culture because of its low productivity in a submerged culture, however the reason was not known. In this study, 4.92 g/L of cordycepin was produced at the 15th day of C. militaris NBRC 103752 liquid surface culture, but only 1 mg/L was produced in the submerged culture. RNA-Seq was used to clarify the gene expression profiles of the cordycepin biosynthetic pathways of the submerged culture and the liquid surface culture...

Cordycepin is an active component extracted from Traditional Chinese medical herb Cordyceps militaris. Many reports demonstrated that cordycepin harbors antitumor activity in a broad spectrum of cancer types. In this study the actions and the underneath molecular mechanisms of cordycepin were investigated in renal cell carcinoma Caki-1 cell line. Results showed that cordycepin induced apoptotic cell death and inhibited cell migration in Caki-1 cells. Quantitative real-time PCR results and western blot analyses indicated cordycepin dose-dependently decreased microRNA-21 expression and Akt phosphorylation levels in Caki-1 cells, but increased PTEN phosphatase levels...

Cordycepin (COR) and pentostatin (PTN) are adenosine analogs with related bioactivity profiles as both mimic adenosine and can inhibit some of the processes that are adenosine dependent. Both COR and PTN are also natural products and were originally isolated from the fungus Cordyceps militaris and the bacterium Streptomyces antibioticus, respectively. Here, we report that not only is PTN produced by C. militaris but that biosynthesis of COR is coupled with PTN production by a single gene cluster. We also demonstrate that this coupling is an important point of metabolic regulation where PTN safeguards COR from deamination by inhibiting adenosine deaminase (ADA) activity...

Mulberry (Morus alba) leaves are known to have therapeutic effects on lipid metabolism including lipogenesis, lipolysis and hyperlipidemia. However, novel compounds with strong lipolytic ability among 27 extracts of the mulberry leaves fermented with Cordyceps militaris (EMfCs) have not yet been identified. Therefore, the cAMP concentration and cell viability were measured in the primary adipocytes of SD (Sprague Dawley) rats and 3T3-L1 cells after treatment of 27 EMfCs. Briefly, mulberry leaves powders amended with three different concentrations (0, 25 and 50%) of silkworm pupae (SWP) powder were fermented with 10% C...

Ophiocordyceps sinensis is one rare medicinal fungus produced in the Qinghai-Tibetan Plateau. Its quality and price varies hugely with different habitat, and its numerous substitutes have sprung up in functional food markets. This paper aims to discriminate the geographic origin of wild O. sinensis and its substitutes via element analyzer-isotope ratio mass spectrometry and gas chromatography-isotope ratio mass spectrometry. The δ(13)C values of major fatty acids in the lipids of O. sinensis are characterized unanimously by the variation relation C18:0 < C18:2 ≈ C16:0 < C18:1, while their fluctuation intervals are notably different between those of neutral and polar lipids...

A decarboxylase (IfPAD) from the ascomycete Isaria farinosa converted ferulic acid to 4-vinylguaiacol (4-VG), a volatile which imparts the distinct "smoke flavor" of pyrolized wood. The activity was enhanced by adding (E)-ferulic acid to the culture medium and peaked with 3.6 U g(-1) mycelium (1 μmol 4-VG min(-1)). The coding sequence of 543 bp was translated into a 25 kDa protein with a homology of 91 % to putative phenolic acid decarboxylases of its teleomorph, Cordyceps militaris, and Beauveria bassiana, the anamorph of Cordyceps bassiana...

Bladder cancer is a neoplasm originated from bladder epithelial cells. The therapy for bladder cancer is so far not satisfactory. In this study, we examined the effects of Cordyceps militaris hot water extracts containing cordycepin on human bladder cells. Cordyceps militaris hot water extracts containing cordycepin was used to treat human T24 bladder carcinoma cells, and we found that Cordyceps militaris hot water extracts containing cordycepin decreased T24 cell survival in a dose-dependent manner, which was seemingly mediated by activation of A3 adenosine receptor and the subsequent inactivation of Akt pathways, resulting in increases in cleaved Caspase-3 and apoptosis...
