Abstract: Glyphosate is a widely used broad spectrum herbicide, reported to induce various toxic effects in non-target species, but its carcinogenic potential is still unknown. Here we showed the carcinogenic effects of glyphosate using 2-stage mouse skin carcinogenesis model and proteomic analysis. Carcinogenicity study revealed that glyphosate has tumor promoting activity. Proteomic analysis using 2-dimensional …

Abstract: To improve the probability of detecting unintended side effects during maize gene manipulations by bombardment, proteomics was used as an analytical tool complementary to the existing safety assessment techniques. Since seed proteome is highly dynamic, depending on the species variability and environmental influence, we analyzed the proteomic profiles of one transgenic maize variety (event …

Abstract: Glyphosate-based herbicides (GBH) are one of the most used herbicide nowadays, whilst there is growing concern over their impact on aquatic environment. Since data about the early proteomic response and toxic mechanisms of GBH in fish is very limited, the aim of this study was to investigate the early toxicity of GBH in the …

Abstract: Roundup® is a glyphosate-based herbicide (GBH) used worldwide both in agriculture and private gardens. Thus, it constitutes a substantial source of environmental contaminations, especially for water and soil, and may impact a number of non-target organisms essential for ecosystem balance. The soil filamentous fungus Aspergillus nidulans has been shown to be highly affected by …

Abstract: Cyanobacterial toxins and pesticides regularly impact freshwaters. Microcystin-LR is one of the most toxic and common cyanobacterial toxins whereas glyphosate is the active ingredient of a widely use herbicide. As filter feeders, freshwater mussels are particularly exposed. Like many native bivalve species, Unio pictorum suffers from a continuous decline in Europe. In order to …

Abstract: This work evaluates the activity of a few key enzymes involved in combating reactive oxygen species (ROS), such as ascorbate peroxidase (EC 1.11.1.11), catalase (EC 1.11.1.6), glutathione reductase (EC 1.6.4.2), and superoxide dismutase (EC 1.15.1.1), as well as the concentration of malondialdehyde and hydrogen peroxide in transgenic and non-transgenic soybean leaves. Additionally, differential protein species …

Abstract: Laser ablation inductively coupled plasma mass spectrometry is used for determining Fe in leaves of transgenic (variety M 7211RR) and non-transgenic (variety MSOY 8200) soybean, grown for 21 days in a growth chamber at controlled temperature (27 ± 0.1 °C) and photoperiod (12 h). The same technique, but in the imaging mode, is also …

Abstract: Assessing the risks of genetically modified organisms (GMOs) is required by both international agreement and domestic legislation. Many view the use of the “omics” tools for profiling classes of molecules as useful in risk assessment, but no consensus has formed on the need or value of these techniques for assessing the risks of all …
