Neonatal taurine administration modifies metabolic programming in male mice

Area of Science:

• Biochemistry
• Endocrinology
• Neonatal Nutrition

Background:

• Taurine, a semi-essential amino acid, plays a role in glucose homeostasis.
• It is commonly supplemented in infant formulas and parenteral solutions for premature infants.

Purpose of the Study:

• To investigate the long-term effects of neonatal taurine administration on adult glucose metabolism in rodents.

Main Methods:

• Neonatal mice received daily taurine (50 mg/kg) or vehicle for the first 21 days of life.
• Adult glucose and insulin tolerance tests were performed.
• Plasma lipids and malondialdehyde (MDA) levels were measured.

Main Results:

• Adult mice treated with taurine neonatally exhibited lower basal glucose levels.
• Lower incremental Area Under the Curve (iAUC) after glucose loading was observed in taurine-treated mice.
• No significant changes were found in iAUC after insulin loading, plasma lipids, or MDA levels.

Conclusions:

• Neonatal taurine administration in rodents results in enduring positive effects on glucose homeostasis into adulthood.
• These findings suggest a potential therapeutic role for taurine in managing glucose metabolism.
