Cordycepin, a metabolite of Cordyceps militaris, inhibits xenograft tumor growth of tongue squamous cell carcinoma in nude mice / 南方医科大学学报

OBJECTIVE@#To evaluate the inhibitory effect of cordycepin on oral cancer xenograft in nude mice and explore the underlying mechanisms.@*METHODS@#Sixteen BALB/c mice bearing subcutaneous human tongue squamous cell carcinoma (TSCC) TCA-8113 cell xenografts were randomized into model group and cordycepin treatment group for daily treatment with saline and cordycepin for 4 weeks. After the treatment, the tumor xenografts were dissected and weighed to assess the tumor inhibition rate. Histological changes in the heart, spleen, liver, kidney, and lung of the mice were evaluated with HE staining, and tumor cell apoptosis was examined using TUNEL staining; The expressions of Bax, Bcl-2, GRP78, CHOP, and caspase-12 in the xenografts were detected using RT-qPCR and Western blotting.@*RESULTS@#Cordycepin treatment resulted in a tumor inhibition rate of 56.09% in the nude mouse models, induced obvious changes in tumor cell morphology and significantly enhanced apoptotic death of the tumor cells without causing pathological changes in the vital organs. Cordycepin treatment also significantly reduced Bcl-2 expression (P < 0.05) and increased Bax, GRP78, CHOP, and caspase-12 expressions at both the RNA and protein levels in the tumor tissues.@*CONCLUSION@#Cordycepin treatment can induce apoptotic death of TCA-8113 cell xenografts in nude mice via the endogenous mitochondrial pathway and endoplasmic reticulum stress pathways.
