Cloned (Comment) Organism
SSAT overexpression in prostate cancer cells leads to a massive increase in intracellular and extracellular acetylated spermidine and to a 6-20fold increase in biosynthetic enzyme activities, overview. In the presence of 4-fluoro-ornithine, SSAT overexpression leads to the sequential appearance of fluorinated putrescine, spermidine, acetylated spermidine, and spermine Homo sapiens
