- Mothers breast milk can help preterm babies to get metabolic boost
The team of researchers examined whether there were differences in the composition of the breastmilk's microRNAs, snippets of RNA that affect gene expression and can be passed to the baby. "We found that there are differences in these microRNA profiles, and that the majority of the altered microRNAs influence metabolism," said Molly Carney, a medical student at Penn State University.
"If those microRNAs are being transferred to the infant that could potentially impact how the newborn processes energy and nutrients," Carney added.
Babies born prematurely are at a major risk of developing host of problems, including failure to thrive and neurodevelopmental delays. The babies also tend to be born at a lower weight than the term infants. Therefore, preterm babies have different nutritional needs than the term babies.
Researchers collected 36 samples of breastmilk from mothers with infants born at term and 31 samples from mothers with babies born prematurely. Then they processed the samples in the lab, extracting microRNAs and comparing them to the human genome to pinpoint the differences between premature and term breast milk. After the analysis was done, they identified about nine microRNAs that were considerably different in the premature breast milk.
"We know that babies born prematurely have better health outcomes with breast milk than with formula, and our results may explain some of these health benefits associated with breast-feeding," said Steven Hicks, assistant professor at Penn State.
