title: Differential modulatory effects of clarithromycin on the production of cytokines by a tumor.
abstract: In vitro treatment with clarithromycin inhibited the expression of the matrix metalloproteinase-9, transforming growth factor beta, and tumor necrosis factor alpha genes in 13762NF rat mammary adenocarcinoma cells. Transient enhancement, rather than inhibition, was observed for the interleukin-6 gene, and no significant change was observed for the tissue inhibitor of metalloproteinase-2 gene. Such an effect was not observed for cefotiam or gentamicin.
