Short description of ongoing research projects

We are working on discovering the mechanism of action of environmental pollutants on reproduction, mainly tracking effects on steroidogenesis, ovulatory potential, embryonic development and spermatozoa. Within this project we are investigating effects of pollutants during early embryonic exposure on future susceptibility to malformations and diseases, according to concept Developmental Origins of Health and Disease (DOHaD). It is believed that epigenetics holds the key for this mechanism. Therefore, by analyzing DNA methylation we aim to unveil subtle toxicity that manifests later in life. Great deal of our work is oriented towards revealing signaling pathways activated by environmental pollutants using different models.
