Abstract

Cardiorenal syndrome (SCR) is characterized as a set of cardiac and renal dysfunctions, in which the injury of one organ generates disturbances in the other, Besides, SCR causes a perceptible oxidative imbalance in the plasma due to the fine interaction and relationship between the two systems. The vascular system, responsible for transporting blood throughout the body, is also affected by SCR, through neurohumoral, hemodynamic, biochemical, and oxidative stress factors. The purinergic system is a cell signaling system performed by nucleotides and nucleosides with prominence in vascular function since it mediates vasodilation and vasoconstriction. Also, purinergic system is considered an important anti-apoptotic system when there is a redox imbalance. Thus, the objective of this project is to analyze the possible alteration in the gene expression of purinergic receptors in the vasculature in response to oxidative stress originating from SCR.
