It is even more serious than we thought:

Pesticides Transform Our Genes

Breast cancer is the most common cancer in women. The team of biologist Luc Gaudreau has just highlighted a mechanism which explains how certain pesticides contribute to the development of the disease.

Exposed to more than 7000 pesticides

The quantities of pesticides used in agriculture have increased steadily for decades. More than 7000 products are marketed in Canada and each of them contains one or more of the 500 approved active ingredients. In town or in the country, we are all exposed to low levels of pesticides. Their long-term effects, which are poorly understood, raise serious concerns.

Luc Gaudreau, who holds the Canada Research Chair in mechanisms of gene transcription, studies the mechanisms that orchestrate the communication and transmission of genetic information in cells. The molecular biologist is also a researcher at the Pharmacology Institute of Sherbrooke. In particular, he is working to better understand how pollutants incorporate molecular machinery to initiate certain cancers, including breast cancer. A complex project for which Luc Gaudreau has just obtained a research grant from the Cancer Research Society. The researcher also believes he has found a suspect: Dnmt3B, an enzyme involved in the transformation of our DNA.

When the balance is upset

"When pollutants enter the cells of the body, the latter trigger a defense mechanism," explains the molecular biologist. They activate the AhR receptor ”. This receptor - a protein - is also an important regulator of gene expression. When activated, AhR results in the expression of the two enzymes that detoxify. "The problem is that these same enzymes can also metabolize estrogens," says Luc Gaudreau. Estrogens have long been recognized as a factor involved in the development of breast cancer.

The first enzyme (CYP1A1) turns estrogen into a harmless compound. But the second (CYP1B1) converts estrogen into 4-hydroxy-estradiol - a compound whose effects on the genome are harmful. The natural balance of these two metabolites is precious: it must be in favor of the non-harmful compound, and therefore prevent an overproduction of 4-hydroxy-estradiol. Unfortunately, the presence of pollutants in the body and the mechanisms that govern the actions of estrogen upset this healthy balance. Result: an overproduction of 4-hydroxy-estradiol, highly genotoxic, in the mammary gland. In some cases, this gear can lead to the development of cancer.

Quite a mess for not much, resulting from the magical thought! I have yet to see studies showing that eating organic has a health benefit compared to eating non-organic. On the one hand, the pesticides used in organic farming are less effective, so more is needed, and all the more so as, since they are less varied, the pests become more accustomed to them. And all are far from harmless, especially copper, much more dangerous than glyphosate.

In the following study, the toxicological effects of exposure to synthetic chemicals are examined but in the context of exposure to natural chemicals.

99,99% of pesticides in the American diet are chemicals that plants produce for self-defense.

Of the 52 natural pesticides tested in high dose animal carcinogenicity tests, approximately half (27) are carcinogenic to rodents ; these 27 are found in several common foods.

The conclusion of the study:
"We conclude that natural and synthetic chemicals are equally likely to be positive in animal cancer tests. We also conclude that at low doses of most human exposures, the comparative hazards of synthetic pesticide residues are negligible."
