WebMTX was dissolved in water at 1 mg/mL. The stock solution was diluted further in RPMI-1640 to the final concentration required. To ensure that a complete sigmoidal cytotoxicity concentration curve could be observed, the following drug concentrations were studied: 0.01, 0.03, 0.05, 0.1, 0.5, 1, 5, and 10 μM. WebHowever, the addition of 0.1, 0.5, or, 1 mM 8-Br-cAMP to the medium significantly shifted the TNF-α cytotoxicity curve upward and to the left in a concentration-dependent manner. Maximum cytotoxicity of TNF was increased to 74 ± 0.1% with 1 mM 8-Br-cAMP (P < 0.05) and 50% cytotoxicity occurred at 25 pg/ml TNF vs. 200 pg/ml in the absence of 8 ...
