Creatine Synthesis and Transport in the Fetus - Critical Regulation of Energy Supply for Fetal Growth & Survival?

Funded Activity Summary

Survival at birth depends on the baby being able to breathe effectively, to maintain adequate blood flow to every organ, and for the brain to coordinate these activities. Failure of any one of these will result in death. In this application we propose that the ability of the fetus and newborn baby to obtain adequate supplies of CREATINE is essential for survival, because this substance is essential for maintaining energy turnover in all cells in the body. In the adult, CREATINE is obtained either from the diet (after absorption from the gut), or after synthesis in, and release from the liver. We do not know how fetal tissues obtain CREATINE, but we do know that when CREATINE is too low the fetus is likely to die, and that if extra CREATINE is supplied in the mother's diet the fetus is more likely to survive profound asphyxia at birth. In this project, in pregnant animals we will determine if fetal tissues can synthesize and take up CREATINE, and if providing extra CREATINE in the maternal diet throughout pregnancy can protect the heart, brain and breathing apparatus from the damaging effects of asphyxia or low oxygen (hypoxia). If successful, we will have developed a new treatment for pregnant women that protects their unborn baby from the dangers of birth asphyxia.
