Autocrine stimulation of interleukin-1 in the growth of human thyroid carcinoma cell line NIM 1.
We reported first in this study that human thyroid cell line NIM 1 established from a patient with papillary adenocarcinoma of the thyroid associated with hypercalcemia and peripheral neutrocytosis produced interleukin (IL)-1 alpha and IL-1 beta in the culture supernatant and cell lysate as detected by murine thymocyte proliferative response and enzyme-linked immunosorbent assay. Production of IL-1 alpha and IL-1 beta was further confirmed by the demonstration of IL-1 alpha and IL-1 beta messenger ribonucleic acid expression with Northern blot hybridization analysis. The in vitro growth of NIM 1 cells was inhibited by the addition of anti-IL-1 alpha and IL-1 beta antibody. The growth of NIM 1 cells was further enhanced by the addition of recombinant human IL-1 alpha and IL-1 beta, whereas this enhancement was also inhibited by the addition of anti-IL-1 antibody. IL-1 receptors were expressed on NIM 1 cells. These results suggest that IL-1 plays a regulatory role in the growth of NIM 1 cells by an autocrine mechanism.
