BPA Is Deadly To The Developing Brains Of Babies In Utero, New Study Shows

NaturalNews March 2 2013

Scientists from Duke University in North Carolina have identified yet another major threat to human health posed by the plastics chemical bisphenol-A (BPA).

According to new research, babies exposed to BPA in utero, or during their developmental stages in the womb, could experience inhibited central nervous system development, which in turn could set them up for future stricken with neurodevelopmental problems.

Because it mimics the actions of estrogen, BPA is already known to interfere with the body’s endocrine system, causing a host of potential problems ranging from behavioral and weight abnormalities to reproductive and immune disorders.

And while awareness of BPA’s dangers is on the rise all across the globe, there is still a minimal understanding as to how BPA exerts these negative effects, including how the chemical interferes with proper nervous system development.

So to gain a further understanding, researchers from Duke initiated a series of experiments designed to pinpoint the precise mechanisms by which BPA alters proper brain development.

What they found is that BPA alters chloride levels inside cells by shutting down a gene known as KCC2 that is responsible for producing the KCC2 protein.

Without this gene, cells are unable to properly transport chloride out of cells, which ends up damaging neural circuits and compromising normal brain development.

“It disrupts this process and it corrupts this process,” explained Dr. Wolfgang Liedtke, lead author of the study, to WUNC about BPA’s obstruction of the KCC2 gene.

Researchers Link BPA To Reproductive Problems, Abnormal Egg Development

Natural Society | September 26 2012

A new animal study links bisphenol-A (BPA) exposure in females in utero with reproductive problems later in life, including abnormal egg development.

“All the eggs that a female is going to have in her lifetime are formed before birth,” says researcher Catherine VandeVoort of University of California, Davis. “Anything that disrupts that process is going to have an impact later in life.”

Impaired Follicles and Division

For the study (which will be published next week in the journal Proceedings of the National Academy of Sciences), scientists put fetal monkeys in two groups. A control group remained unexposed to BPA while another group was exposed to the chemical through daily food during second or third trimesters or through an implant that administered constant, low doses of BPA.

The eggs of fetuses exposed to BPA had difficulty forming follicles, which surround eggs during development. Being unprotected in this manner often leads to eggs dying before maturation, according to VandeVoort.

Other abnormalities seen in the eggs were signs that they would carry too many chromosomes from being unable to divide during development, leading to miscarriages or disorders like Down Syndrome.
