Renal Programming by Transient Postnatal Overfeeding: The Role of Senescence Pathways

Background: Early nutrition influences the risk of Chronic Kidney Diseases development in adulthood. Mechanisms underlying the early programming of altered renal function remain incompletely understood. This study aims at characterizing the role of cell senescence pathways in early programming of Chronic Kidney Disease after transient postnatal overfeeding. Material and Methods: Reduced litters of 3 mice pups and standard litters of 10 mice pups were obtained to induce overfed animals during lactation and control animals, respectively. Animals were sacrificed at 24 days (weaning) or at 7 months of life (adulthood). Body weight, blood pressure, kidney weight, and glomerular count were assess…
