Induction of ornithine decarboxylase in cultured mouse L cells. II. Effects of additions of amino acids and serum.

Induction of ornithine decarboxylase [EC 4.1.1.17] (ODC) in mouse L cells by components of the culture medium was investigated. It was found that further addition of amino acid mixture, but not of calf serum, to confluent cells of 5 day culture induced ODC and that this induction was accelerated by actinactinomycin D. In salt solution, addition of either… CONTINUE READING
