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…
RELATIONSHIP BETWEEN DNA FRAGMENTATION INDEX AND pAKT IN CUMULUS CELLS: NEW MARKERS OF OOCYTE COMPETENCE
The specific LH and FSH polymorphisms could influence the growth of follicles and oocytes.Some studies have shown that certain single nucleotide polymorphisms of FSHR are associated with changes in the ovarian activity, having functional implications in human reproduction. Carriers of polymorphic variant of betaLH show sub-optimal ovarian response to the standard long GnRH-agonist down-regulation protocol, when stimulated with recombinant FSH. No studies have been designed relating the polymorphic variants of FSHR and LHB with the oocyte competence. In previous studies, we demonstrated the correlation between the apoptosis rate and the expression level of some survival pathways molecules, a…
