Regulation by 1,4-diamines of the ornithine decarboxylase activity induced by ornithine in perifused tumor cells.


Ornithine decarboxylase (ODC) activity of Ehrlich carcinoma cells was increased more than 36-fold after being maintained for 3.5 hr in vitro in a special chamber which allowed continuous perifusion with 0.5 mM ornithine; if incubated in vitro without perifusion the ODC activity was, of course, only 9-fold by the same concentration of ornithine. Ornithine… (More)
