The gut-derived hormone, peptide YY (PYY) reduces food intake and enhances satiety in both humans and animals. Obese individuals also have a deficiency in circulating peptide YY, although whether this is a cause or a consequence of obesity is unclear. Our aims were to determine whether peptide YY (PYY) over-expression may have therapeutic effects for the treatment of obesity by altering energy ...
Construction of a taste-blind medaka fish and quantitative assay of its preference–aversion behavior
In vertebrates, the taste system provides information used in the regulation of food ingestion. In mammals, each cell group within the taste buds expresses either the T1R or the T2R taste receptor for preference-aversion discrimination. However, no such information is available regarding fish. We developed a novel system for quantitatively assaying taste preference-aversion in medaka fish. In t...
Food security has a multidimensional nature that an important and strategic priority in protecting consumers of today citizens countries. The application modern biotechnological methods food ingredients products is evaluated terms research development studies legal regulations consumption human health. On the other hand, safe production for detection, management control physical, chemical biolo...
The classical definition of a genetically engineered or “transgenic” animal would be “those animals modified by recombinant DNA (rDNA) techniques” according to the U.S. Food and Drug Administration (United States Food and Drug Administration, Guidance #187, 2009). Thus, the introduction or deletion of any gene by using recombinant DNA would fall into this category. Since the first reports of st...
BACKGROUND In order to provide a system fully integrated with qPCR screening, usually used in GMO routine analysis, as well as being able to detect, characterize and identify a broad spectrum of GMOs in food/feed matrices, two bidirectional DNA walking methods targeting p35S or tNOS, the most common transgenic elements found in GM crops, were developed. These newly developed DNA walking methods...
Growth hormone (GH) transgenic fish have accelerated growth and could improve production efficiency in aquaculture. However, concern exists regarding potential environmental risks of GH transgenic fish should they escape rearing facilities. While environmental effects have been examined in some GH transgenic models, there is a lack of information on whether effects differ among different constr...
Introduction: Genetically modified plants species of plants are produced by the genetic engineering of agricultural science and the addition of specific genes in their genetic sequences with the aim of optimizing the product and creating desirable traits. This study examined the remains of Cry1A(b) and P35 genes in blood of rats fed with genetically modified rice. Methods: This study was exper...
Background and purpose: Transgenic rice is a type of rice that its genetic sequence has been changed to improve its quantity and quality. Bt (Bacillus thuringiensis) transgenic rice expresses Cry1Ab protein and is named Tarom Molaii. There are no studies on the effect of this type of transgenic rice on gastrointestinal health in Iran, so, this study investigated the effect of Tarom Molaii tran...
Over the last decade, proteomics has been successfully applied to the study of quality control in production processes of food (including meat, wine and beer, transgenic plants and milk) and food safety (screening for food-derived pathogens). Indeed, food quality and safety and their influence on the health of end consumers have growingly become a founding principle in the international agenda ...
Abstract Transgenic plants that express double-stranded RNA (dsRNA) targeting vital insect genes have recently emerged as a valuable new tool for pest control. In this study, tobacco were transformed to produce dsRNA Sl 102 gene is involved in the immune response of Spodoptera littoralis larvae, serious lepidopteran several crops. Experimental larvae reared on transgenic lines showed (1) strong...
