Plastic chemical phthalate causes DNA breakage and chromosome defects in sex cells, new study finds
A new study conducted on roundworms finds that a common plastic ingredient causes breaks in DNA strands, resulting in egg cells with the wrong number of chromosomes. Monica Colaiácovo of Harvard Medical School led the study, which was published October 24 in the journal PLOS Genetics.
Great, let's just make society more dysgenic, shall we?A new study conducted on roundworms finds that a common plastic ingredient causes breaks in DNA strands, resulting in egg cells with the wrong number of chromosomes.
So in other words, it's everywhere!Benzyl butyl phthalate (BBP) is a chemical that makes plastic more flexible and durable, and is found in many consumer products, including food packaging, personal care products and children's toys.
I'm sure this will have no long-term consequential impacts upon the human populace jfl.Previous studies have shown that BBP interferes with the body's hormones and affects human reproduction and development, but the details of how it impacts reproduction have been unclear.
Fyi, if an egg has an incorrect number of chromosomes it can lead to miscarriage, infertility, and also Down Syndrome.In the new study, researchers tested a range of doses of BBP on the nematode Caenorhabditis elegans and looked for abnormal changes in egg cells. They saw that at levels similar to those detected in humans, BBP interferes with how newly copied chromosomes are distributed into the sex cells. Specifically, BBP causes oxidative stress and breaks in the DNA strands, which lead to cell death and egg cells with the wrong number of chromosomes.
This is something which I encourage everyone to pay attention to, since while we all do agree genetics is heritable, certain factors could potentially alter their gene-expression.Based on these findings, the researchers propose that BBP exposure alters gene expression in ways that cause significant damage to the DNA, ultimately leading to lower quality egg cells with abnormal chromosomes.
