Developmentally, PEPC activity was higher at the rapid elongation phase than that at the slow elongation stage.

Conclusions: Gene expression changes are associated with the rapid elongation that occurs around the optic nerve region during the development of myopia.

Early embryonic development in the pig is characterized by a rapid elongation of the conceptus trophectoderm on days 11-12 of gestation.

RT-PCR analyses revealed that GhPEPC1 and 2 were highly expressed at the rapid elongation phase but weakly at the slow-to-terminal elongation period.
