Gene expression changes after parental exposure to metals in the sea urchin affect timing of genetic programme of embryo development
2021
Simple Summary Intergenerational and transgenerational effects, in which exposure to stressors in a parental generation affects the phenotype of the offspring have been connected to anthropic impacts on biological systems. Therefore, environmental stress experienced inside a generation, particularly during gametogenesis, may lead to erroneous patterns in their offspring just emerging at early developmental stages. In this scenario, the sea urchin embryo represents a suitable model for integrating analyses of gene expression through embryogenesis with developmental alteration induced by environmental stressors. Herein we provide pieces of evidence for the alteration of the gene regulatory ne…
Can Early Life Exposure to Permethrin lead to intergenerational effects?
2016
Pesticides are largely used in agriculture against pests and consequently are present in fruits and vegetables. The wide presence of pesticide residues in breast milk underline the risk for the population, focalizing the long-term consequence of early life pyrethroid exposure. The significant presence of pyrethroid metabolites in the urine of population over the world confirms that their presence in food is a global problem. It has been demonstrated that there is a correlation between the environmental exposure to pesticides and the development of neurodegenerative diseases. Neonatal exposure to Permethrin (PERM), a member of the family of synthetic pyrethroids, can induce neurodegeneration…
