Abstract excerpt
Constitutive up-regulation of interleukin-6 (IL-6) gene expression is observed in many neoplastic cell lines. The contribution of mutations in p53 to the up-regulation of the IL-6 promoter was evaluated in transient transfection experiments. In HeLa cells, wild-type (wt) human or murine p53 preferentially repressed the IL-6 promoter. The p53 mutants Val-135 and Phe-132 up-regulated IL-6 promoter activity in these...
