Genetically modified corn and liver toxicity

According to this work, consumption of MON 863 corn disturbs numerous biological parameters in rats to a greater or lesser extent: weight of the kidneys, weight of the liver, the level of reticulocytes (new red blood cells), the level of triglycerides, etc. Urinary chemistry is also changed, with reductions in excreted sodium and phosphorus going as high as 35 percent. The effects vary with the sex of the animals. "Female rats exhibit an increase in blood fat and sugar levels, and an increase in body weight - all associated with greater hepatic sensitivity," says Mr. Seralini, principal author of this study and, moreover, president of the Research Committee for Independent Research and Information on Genetic Engineering (Criigen). "Among males, the impact is opposite, with a drop in body and kidney weights."

The corn in question, MON863, is made by the Monsanto Company and approved for use in Australia, Canada, China, the European Union, Japan, Mexico, the Philippines, and the United States. It has had a gene inserted from the bacteria Bacillus thuringiensis (Bt), which causes the plant's cells to produce a pesticide.
