Randomized trial reveals that inhibiting L-ornithine decarboxylase arrests embryonic development, indicating its essential role in mammals.

To investigate the role of L-ornithine decarboxylase in early embryonic development in mammals.
Used DL-alpha-difluoromethylornithine to inhibit L-ornithine decarboxylase activity in mouse, rat, and rabbit models.
Monitored the impact of inhibition on uterine enzyme activity and embryonic development stages.
L-ornithine decarboxylase activity suppression led to arrested embryonic development in early stages.
An increase in putrescine concentration is essential for continued embryonal growth following implantation.

Fozard et al. (1980) studied this question.
