title: [Anti-neoplastic activity of a human recombinant tumor necrosis factor (Hu-rec-TNF) alone or in combination with human recombinant gamma-interferon, doxorubicin or cis-platinum on a human renal cell carcinoma line].
abstract: The inhibitory effect of human-recombinant tumor necrosis factor (Hu-rec-TNF) alone or in combination with human recombinant gamma-interferon (rec gamma-IFN), doxorubicin (ADM) or cis-platinum (CDDP) was studied for two human renal cell carcinoma lines (KO-RCC-1 and RCC-nu-1 cells). Hu-rec-TNF inhibited the cell growth of KO-RCC-1 cells in a dose- and time-dependent manner. The inhibitory effect was seen 48 hours after the treatment with Hu-rec-TNF alone. The effect of Hu-rec-TNF was cytotoxic in our experiment. On the other hand, Hu-rec-TNF did not inhibit the cell growth of RCC-nu-1 cells. There were sensitive and resistant cells in renal cell carcinoma. In KO-RCC-1 cells, Hu-rec-TNF enhanced the inhibitory effect of rec gamma-IFN, ADM or CDDP. On the other hand, Hu-rec-TNF did not enhance the inhibitory effect of rec gamma-IFN, ADM or CDDP in RCC-nu-1 cells. In our experiment, the combined treatment with Hu-rec-TNF and rec gamma-IFN, ADM or CDDP was useful in human renal cell carcinoma which was sensitive for Hu-rec-TNF.
