Expression of cytosolic acetyl-CoA synthetase gene is developmentally regulated.
Acetyl-CoA synthetase (AceCS) provides acetyl-CoA for different physiological processes, such as fatty acid and cholesterol synthesis, as well as the citric acid cycle. We show here that the cytosolic isoform of this enzyme, AceCS1, is expressed during mouse development. In the embryonic stage E9.5 AceCS1 transcripts localize in the cephalic region. At E10.5 the cephalic expression intensifies and transcripts appear also in the spinal cord and in the dorsal root ganglions. During organogenesis AceCS1 is expressed in the liver from E11.5. The AceCS1 gene is expressed also in the testes from E12.5 onwards and expression localizes in the interstitial Leydig cells. In the ovaries, expression is transient and AceCS1 transcripts are detected from E13.5 to E15.5 in the ovarian interstitial component. In the kidneys AceCS1 transcripts appear in a subset of the renal tubules at E16.5 and remains in these structures in newborns. Hence, expression of AceCS1 is developmentally regulated suggesting a role for AceCS1 during embryogenesis.
