| Popis: | • The cytotoxicity of dactinomycin (actinomycin D), doxorubicin hydrochloride (Adriamycin), cisplatin, fluorouracil, and methotrexate alone and in combination with recombinant human tumor necrosis factor (rHuTNF) on human squamous cell carcinoma lines was studied by an MTT proliferation assay. The rHuTNF alone caused no inhibition after 24 to 72 hours. All lines investigated showed a dose-dependent response to dactinomycin and doxorubicin. Potentiation of dactinomycin and doxorubicin cytotoxicity occurred with four of six cell lines following incubation of rHuTNF and the drug. No synergistic effect on cytotoxicity was seen with rHuTNF and any chemotherapeutic agent on two cell lines. The addition of rHuTNF did not augment the cytotoxic effect seen with cisplatin, methotrexate, or fluorouracil on any cell line. These results show that rHuTNF can enhance the cytotoxic effect of certain chemotherapeutic agents on squamous cell lines in vitro. ( Arch Otolaryngol Head Neck Surg . 1990;116:436-439) |
