Sperm p53 concentration: a potential new biomarker for environmental pollution. Preliminary data.(EcoFoodFertility Project)

Study question:We evaluated the p53 protein concentration in spermcells to test whether environmental pollution can affect expression levels of this protein. Summary answer:We found a significant difference in p53 levels between two homogeneous groups by age and lifestyle, residents in two areas with different environmental impact. What is known already:TheWorld HealthOrganization (WHO) has placed among its priority objectives the understanding of the relationships between the sources of pollution and the effects on human health, which they represent a cause of surprisingly high mortality and morbidity. International scientific literature shows that strong environmental impact may jeopardiz…
