Increased phosphatidylcholine production but disrupted glycogen metabolism in fetal type II cells of mice that overexpress CTP:phosphocholine cytidylyltransferase.

Abstract excerpt

CTP:phosphocholine cytidylyltransferase (CCT) is a rate-determining enzyme in the de novo synthesis of phosphatidylcholine (PtdCho). Alveolar type II cells synthesize large quantities of disaturated PtdCho, the surface-active agent of pulmonary surfactant, particularly at late gestation when the lung prepares itself for postnatal air breathing. To clarify the role of CCTalpha in lung surfactant maturation, we...
