Research Abstract

CMP-sialic acid synthetase (CSS) is a prerequisite enzyme in sialic acid biosynthesis and localizes in the nucleus. First, we showed that the protein expression of CSS was regulated by proteasome in NIH3T3 cells. Then, The knockdown of CSS in medaka (Oryzias latipes) embryo using morpholino antisense oligo technique lead to the fatal lethality.
