In this study, the effect of cordycepin (3'-deoxyadenosine), a major component of Cordyceps militaris, an ingredient of traditional Chinese medicine was investigated for the first time on apoptotsis in human neuroblastoma SK-N-BE(2)-C and melanoma SK-MEL-2 cells. Cordycepin significantly inhibited the proliferation of human neuroblastoma SK-N-BE(2)-C and human melanoma SK-MEL-2 cells with IC50 values of 120 microM and 80 microM, respectively. Cordycepin treatment at 120 microM and 80 microM, respectively, induced apoptosis in both cells and caused the increase of cell accumulation in a time-dependent manner at the apoptotic sub-G1 phase, as evidenced by the flow cytometry (FCM) and annexin V-fluorescein isothiocyanate (FITC) analyses. Western blot analysis revealed the induction of active caspase-3 and poly(ADP-ribose)polymerase (PARP) cleavage by cordycepin treatment. These results suggest that cordycepin is a potential candidate for cancer therapy of neuroblastoma and melanoma.

UI MeSH Term Description Entries
D008545 Melanoma A malignant neoplasm derived from cells that are capable of forming melanin, which may occur in the skin of any part of the body, in the eye, or, rarely, in the mucous membranes of the genitalia, anus, oral cavity, or other sites. It occurs mostly in adults and may originate de novo or from a pigmented nevus or malignant lentigo. Melanomas frequently metastasize widely, and the regional lymph nodes, liver, lungs, and brain are likely to be involved. The incidence of malignant skin melanomas is rising rapidly in all parts of the world.

D009447 Neuroblastoma A common neoplasm of early childhood arising from neural crest cells in the sympathetic nervous system, and characterized by diverse clinical behavior, ranging from spontaneous remission to rapid metastatic progression and death. This tumor is the most common intraabdominal malignancy of childhood, but it may also arise from thorax, neck, or rarely occur in the central nervous system. Histologic features include uniform round cells with hyperchromatic nuclei arranged in nests and separated by fibrovascular septa. Neuroblastomas may be associated with the opsoclonus-myoclonus syndrome.

D017209 Apoptosis A regulated cell death mechanism characterized by distinctive morphologic changes in the nucleus and cytoplasm, including the endonucleolytic cleavage of genomic DNA, at regularly spaced, internucleosomal sites, i.e., DNA FRAGMENTATION. It is genetically programmed and serves as a balance to mitosis in regulating the size of animal tissues and in mediating pathologic processes associated with tumor growth.
