Cordycepin Suppresses Thymic Stromal Lymphopoietin Expression via Blocking Caspase-1 and Receptor-Interacting Protein 2 Signaling Pathways in Mast Cells.
    Biological & pharmaceutical bulletin, 2016, Volume: 39, Issue:1

    Cordycepin (3'-deoxyadenosine) is one of the active components isolated from Cordyceps militaris, and has been shown to have anti-inflammatory, anti-oxidant, anti-aging, and anti-cancer effects. Mast cell-derived thymic stromal lymphopoietin (TSLP) plays an important role in the pathogenesis of allergic inflammatory reactions. Here, we investigated the regulatory effect and mechanisms of cordycepin on the expression of TSLP in the human mast cell line, HMC-1 cells, and in the human keratinocyte cell line, HaCaT cells. Cordycepin significantly decreased the production and mRNA expression of TSLP through the inhibition of caspase-1 and nuclear factor-κB activation. Cordycepin also significantly reduced the phosphorylation of receptor-interacting protein 2 and inhibitory kappa B (IκB) kinase β. Cordycepin significantly decreased the production and mRNA expression of interleukin (IL)-8, IL-1β, IL-6, and tumor necrosis factor-α in activated HMC-1 cells. Moreover, cordycepin significantly decreased the levels of TSLP in activated HaCaT cells. Our studies suggest that cordycepin can be applied to the treatment of allergic inflammatory diseases exacerbated by TSLP.

Cordycepin induced eryptosis in mouse erythrocytes through a Ca2+-dependent pathway without caspase-3 activation.
    Archives of toxicology, 2007, Volume: 81, Issue:12

    Cordyceps sinensis is a prized traditional Chinese medicine and its major component cordycepin is found to have anti-leukemia activities. However, its cytotoxicity in erythrocytes was unclear. To examine the effect of cordycepin on the induction of eryptosis (an apoptosis-like process in enucleated erythrocytes), flow cytometric assays based on membrane integrity and asymmetry were employed. For comparison, analyses were performed in parallel with two other anti-leukemia agents, indirubin 3'-monoxime (IDM) and As2O3. We found that at the IC50 against leukemia HL-60, cordycepin elicited eryptosis while IDM and As2O3 showed no erythrotoxicity in mouse erythrocytes. Mechanistically, cordycepin increased the [Ca2+]i and activated mu-calpain protease in a dose-dependent manner. Yet, no caspase-3 activation was observed in the cordycepin-treated erythrocytes. When extracellular Ca2+ was depleted, both the cordycepin-induced eryptosis and mu-calpain cleavage were suppressed. Our study therefore demonstrated for the first time that cordycepin induces eryptosis through a calcium-dependent pathway in the absence of mitochondria and caspase-3 activation.
