Abstract
The expression and the effect of IL-6 were examined in human gastric carcinoma cell lines to determine whether IL-6 serves as a growth stimulator. The expression of IL-6 mRNA was detected in three (TMK-1, MKN-1, MKN-7) of 8 gastric carcinoma cell lines. All three cell lines secreted IL-6 into the culture fluid, in large amounts in the cases of MKN-1 and MKN-7 cells. Scatchard plot analysis of IL-6 binding revealed that MKN-1 and MKN-7 cells had both high- and low-affinity receptors. Cell growth of MKN-1 and MKN-7 cells was stimulated by IL-6, while anti-IL-6 antibody inhibited growth. The expression of IL-1 alpha mRNA by these three cell lines was induced by IL-6. IL-1 alpha increased the expression of mRNA for IL-6 by TMK-1 cells. These findings indicate that IL-6 induced by IL-1 alpha is an autocrine growth factor for some gastric carcinomas.Entities:
