Abstract：
:The effects of Escherichia coli endotoxin upon mouse L929 cell proliferation, DNA synthesis, protein synthesis, and proline incorporation were determined. It was found that a level of endotoxin which inhibited cell proliferation prompted a similar inhibition of DNA synthesis and overall cell protein synthesis. In contrast, endotoxin was shown to inhibit incorporation of proline into cell protein to a significantly greater extent.
