Calik A, Emami NK, White MB, Dalloul RA. Fate of transgenic soybean DNA and immune response of broilers fed genetically modified DP-3Ø5423-1 soybean. Poult Sci 2024; 103:103499. [PMID: 38330889 PMCID: PMC10864803 DOI: 10.1016/j.psj.2024.103499] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/24/2023] [Revised: 01/02/2024] [Accepted: 01/21/2024] [Indexed: 02/10/2024] Open
Abstract
Increased use of genetically modified (GM) plants in the food and feed industry has raised several concerns about the presence of unwanted genes in the food chain and potential associated health risks. In recent years, several studies have compared the nutrient contents of GM crops to conventional counterparts, and some have also tracked the fate of novel DNA fragments and proteins in the gastrointestinal (GIT) and their presence in several tissues. This study was conducted to investigate the fate of transgenic PHP19340A DNA fragment containing gm-fad2-1 (Soybean Event DP-3Ø5423-1) gene in digestive tract contents, blood, internal organs, and muscle tissues. The effects of feeding DP-3Ø5423-1 full-fat soybean meal (FFSBM) to broiler chickens on immune response and blood profiles were also evaluated on d 35. Day-old Ross 308 birds (n = 480) were randomly allocated to 24 floor pens in a 2 × 2 factorial arrangement with diet and gender as main factors. Birds were fed diets containing 20% of either DP-3Ø5423-1 or non-GM FFSBM for 35 d. Data were subjected to a 2-way ANOVA using the GLM procedure of JMP (Pro13). Based on PCR analysis, transgenic PHP19340A DNA fragment containing gm-fad2-1 gene was degraded throughout the digestive system to reach undetectable level in the cecal digesta. Moreover, there was no transgenic gene translocation to blood, organs, or muscle tissue. Feeding DP-3Ø5423-1 FFSBM to broilers had no effect on mRNA abundance of IL-1β, IL-2, IL-6, IL-12B, IL-17A, IFNγ, TNFα, and NF-κB in the spleen or on blood profile. In conclusion, these findings indicate that the examined transgenic fragment in DP-3Ø5423-1 FFSBM progressively degraded in the GIT and did not translocate into blood or tissues. Along with the immune response and blood profile findings, it can be assumed that DP-3Ø5423-1 soybean is safe and unlikely to pose any health risks to broilers or consumers.

Abstract
Various feeding studies have been conducted with the different species of animals to evaluate the possible transfer of transgenic DNA (tDNA) from genetically modified (GM) feed into the animal tissues. However, the conclusions drawn from most of such studies are sometimes controversial. Thus, in the present study, an attempt has been made to evaluate the fate of tDNA in rabbits raised on GM cotton-based diet through PCR analysis of the DNA extracted specifically from blood, liver, kidney, heart and intestine (jejunum). A total of 48 rabbits were fed a mixed diet consisting variable proportions of transgenic cottonseeds meal (i.e. 0% w/w, 20% w/w, 30% w/w and 40% w/w) for 180 days. The presence of transgenic DNA fragments (Cry1Ac, Cry2A and CP4 EPSPS) or plant endogenous gene (Sad1) was traced in those specific tissues and organs. The presence of β-actin (ACTB) was also monitored as an internal control. Neither the transgenic fragments (459 bp of Cry1Ac gene, 167 bp of Cry2A gene and111 bp of CP4 EPSPS gene) nor cotton endogenous reference gene (155 bp of Sad1) could be detected in any of the DNA samples extracted from the rabbit's tissues in both control and transgenic groups. However, 155 bp fragment of the rabbit's reference gene (ACTB) was recovered in all the DNA samples extracted from rabbit tissues. The results obtained from this study revealed that both plant endogenous and transgenic DNA fragments have same fate in rabbit's tissues and were efficiently degraded in the gastrointestinal tract (GIT).

Abstract
This review explores the possibilities to determine livestock consumption of genetically modified (GM) feeds/ingredients including detection of genetically modified organism (GMO)-related DNA or proteins in animal samples, and the documentary system that is in place for GM feeds under EU legislation. The presence and level of GMO-related DNA and proteins can generally be readily measured in feeds, using established analytical methods such as polymerase chain reaction and immuno-assays, respectively. Various technical challenges remain, such as the simultaneous detection of multiple GMOs and the identification of unauthorized GMOs for which incomplete data on the inserted DNA may exist. Given that transfer of specific GMO-related DNA or protein from consumed feed to the animal had seldom been observed, this cannot serve as an indicator of the individual animal's prior exposure to GM feeds. To explore whether common practices, information exchange and the specific GM feed traceability system in the EU would allow to record GM feed consumption, the dairy chain in Catalonia, where GM maize is widely grown, was taken as an example. It was thus found that this system would neither enable determination of an animal's consumption of specific GM crops, nor would it allow for quantitation of the exposure.

Abstract
Potato tuber is a highly nutritious, wherein genotype and environmental differences are known to exist in the shape, size and nutritional value of potatoes. Owing to its high consumption, potato could be an ideal carrier of health-promoting phytochemicals. Potato cultivars contain many bioactive lipidic compounds such as fatty acids, glycolipids, phospholipids, sterols, tocols and carotenoids, which are highly desirable in diet because of their health-promoting effects. In the scientific literature, information on the content and profile of bioactive lipidic compounds in potato cultivars are few. The concentration and stability of bioactive lipids are affected by many factors such as genotype, agronomic factors, postharvest storage, cooking and processing conditions. In this review levels and composition of bioactive lipids in terms of lipid classes, fatty acids, phytosterols, tocopherols, and caroteinoids distribution in different potato cultivars including genetically modified potato (GMP) were highlighted and discussed. In addition, factors affecting bioactive lipids levels, stability and health benefits are reviewed. In consideration of potential nutritional value, detailed knowledge on lipids of potato cultivars is of major importance.
