London, July 16 (Prensa Latina) The risks of certain diseases during pregnancy vary according to the bad of the baby who controls the level of small molecules known as metabolites in the blood of the mother, today the media specialized publications.
For research, more than 4,000 new mothers were examined, and detailed scientific studies were conducted, such as the badysis of placenta and maternal blood.
Scientists have discovered that the genetic profile of the placentas of the Babies of both bades were very different in relation to bad and one of the unique bad-related placental genes controls the level of the spermine molecule.
This small molecule is a metabolite – a substance involved in metabolism. which plays an important role in cells is even essential for the growth of certain bacteria.
Female placentas had They had much higher levels of the enzyme produced by spermine and mothers had higher levels of a form of this molecule in the blood compared to pregnant mothers with baby boys.
It was also determined that placental cells Children were more sensitive to the toxic effects of a drug that blocked their production, which was a direct experimental evidence of gender-related differences in the placental metabolism of spermine .
Gordon Smith, head of research, said that "during pregnancy and delivery, the baby's gender is at the forefront of many parents' minds, but we do not even think that the placenta has bad. This work shows that the placenta differs profoundly according to bad. "
The differences found are altering the compositional elements of the mother's blood and may even alter the risk of complications of pregnancy," she said.
Smith He pointed out that "a better understanding of these differences could lead to new predictive tests and perhaps even new approaches to reduce the risk of a weak pregnancy. "
