In this paper, Serraglini and others used Monsanto's herbicide-resistant corn variety NK603 to feed mice for two years, which is close to the life span of mice. It was found that these mice died earlier than those fed non-GM corn, and were more likely to suffer from tumors and hormonal imbalance. However, some skeptics point out that there are serious statistical data and other problems in this study. Biology Tong www.ebiotrade.com
However, these doubts have received little attention in France, partly because of the research team's media strategy. The researchers in this study provided some French journalists with the opportunity to browse their papers in advance, but unusually, they prohibited other scientists from browsing and commenting on the matter. Therefore, before the paper was published, there were few voices of doubt. Le Nouvel Observateur first interviewed the research team exclusively, and reported the research in a magazine published on Thursday with a warning cover title: "Yes, genetically modified organisms are poisonous!"
"This puts France in a terrible position on the issue of genetically modified crops," said Marc Fellous, a geneticist at the University of Paris and former director of the HCB Committee. "All the publicity is developing to an adverse effect, and people no longer trust experts." Serraglini has not commented on this matter at present. Biology Tong www.ebiotrade.com
There are many speculations in the major media, and it seems that it will heat up. This week, Serraglini will publish a book entitled Tous cobayes? Are we all guinea pigs? )"。 His research will also be adapted into a film of the same name (directed by Jean-Paul Judd). Biology Tong www.ebiotrade.com
EFSA, the European Food Safety Agency, published a brief statement on its website, affirming the relevance of this paper to the safety issues of genetically modified organisms being monitored, but did not specify how to evaluate this research. The agency is no stranger to Serraglini's work: in 2007, EFSA investigated his paper on Monsanto corn variety MON863 approved by the European Food Safety Agency. At that time, EFSA thought that some assumptions in Serraglini's statistics had "misleading results" and questioned the safety of genetically modified crops mentioned in his article "without perfect scientific reasons".
The content of the paper and scientists' query: biological understanding of www.ebiotrade.com.
Last week, French scientists said that experimental mice fed with genetically modified corn NK603 or exposed to the herbicide used in this grain developed tumors.
NK603 is a genetically modified corn, also known as corn, which is produced by Monsanto, an American agricultural giant, and is resistant to glyphosate herbicide produced by the company. Biology Tong www.ebiotrade.com
The research results have been published in the trade magazine "Food Chemical Toxicology". According to the study, this is the first time that it has been studied on experimental mice for two years, which is also the natural life span of experimental mice.
200 male and female experimental rats were divided into 10 group, and each group had 10 rats. One group, as a "control group", was fed with ordinary feed and white water containing 33% non-genetically modified grains. The other three groups were fed with feed and water containing large doses of glyphosate herbicide, which reflected the different concentrations of herbicide in the food chain. The other six groups were fed with different proportions of NK603, which were 1 1%, 22% and 33% respectively. Some have been exposed to herbicides during grain growth, while others have not.

The researchers found that both NK603 and glyphosate herbicide caused similar harm to the health of experimental mice, whether they were eaten at the same time or alone. Especially in female experimental mice, the proportion of premature death and illness of young mice is particularly high. Sick male mice usually suffer from liver damage, or kidney tumors, skin tumors and digestive system diseases.
In the experiment of 14 months, no cancer was found in the experimental mice in the control group, but in the group fed with NK603 and glyphosate herbicide, 10% to 30% of the experimental mice developed tumors. Biology Tong www.ebiotrade.com
However, at present, some scientists are skeptical. Gé rard Pascal, a toxicologist, said after in-depth reading of peer research reports, "To carry out serious oncology research within two years, several groups of at least 50 mice are needed. But there are only 10 mice. Due to natural death during the experiment, the conclusion is based on too few samples. Moreover, the mice used in the experiment are considered to be naturally prone to breast cancer. "
Professor Mark Flo, former chairman of the French Biomolecular Engineering Committee, pointed out that there is a lack of information about the recipes of experimental mice. "Except for genetically modified corn (2354, -8.00, -0.34%), I don't know what they ate. In addition, corn contains highly carcinogenic mycotoxins. Have you tested the concentration of this toxin? There is no mention of this in the report. "
