Abstract

Soybeans provide a nutritionally complete plant-based protein, containing all nine essential amino acids and bioactive compounds. The food safety of a novel triple-stacked genetically modified (GM) soybean, DBN9004×DBN8002×DBN8205 was evaluated in a 90-day rat feeding study. The GM soybean, developed through conventional hybridization of three GM lines (DBN9004, DBN8002 and DBN8205), incorporates genes conferring resistance to glyphosate (epsps), glufosinate (pat), and lepidopteran pests (cry1Ac, cry2Ab2, and mVip3Aa). One hundred Wistar Han RCC rats were divided into five groups (n=10/sex/group) and fed diets containing 15% or 30% GM soybean, non-GM soybean (Jack), or a basal diet for 90 days. No treatment-related effects on body weight/gain, food consumption/utilization, clinical signs, mortality, ophthalmology, clinical pathology (hematology, prothrombin time, urinalysis, serum chemistry), organ weights, and gross and microscopic pathology were observed in rats fed with the GM soybean compared to the non-GM Jack and the basal-diet group. In rats, the results of this 90-day feeding study suggest that there were no significant differences in safety between GM soybean DBN9004×DBN8002×DBN8205 compared to the non-GM Jack.

期刊介绍： Food and Chemical Toxicology (FCT), an internationally renowned journal, that publishes original research articles and reviews on toxic effects, in animals and humans, of natural or synthetic chemicals occurring in the human environment with particular emphasis on food, drugs, and chemicals, including agricultural and industrial safety, and consumer product safety. Areas such as safety evaluation of novel foods and ingredients, biotechnologically-derived products, and nanomaterials are included in the scope of the journal. FCT also encourages submission of papers on inter-relationships between nutrition and toxicology and on in vitro techniques, particularly those fostering the 3 Rs. The principal aim of the journal is to publish high impact, scholarly work and to serve as a multidisciplinary forum for research in toxicology. Papers submitted will be judged on the basis of scientific originality and contribution to the field, quality and subject matter. Studies should address at least one of the following: -Adverse physiological/biochemical, or pathological changes induced by specific defined substances -New techniques for assessing potential toxicity, including molecular biology -Mechanisms underlying toxic phenomena -Toxicological examinations of specific chemicals or consumer products, both those showing adverse effects and those demonstrating safety, that meet current standards of scientific acceptability. Authors must clearly and briefly identify what novel toxic effect (s) or toxic mechanism (s) of the chemical are being reported and what their significance is in the abstract. Furthermore, sufficient doses should be included in order to provide information on NOAEL/LOAEL values.
