(Created claim: summary (P836): The expression of miRNAs in the preservation solution and blood in a clinical model of suboptimal donors that include donors with expanded criteria or in asystolia, can be biomarkers that allow assessing the viability of the organ during its preservation prior to renal transplantation, identifying the evolution of ischemic renal damage and predicting the development of delayed post-transplant or graft function. Thus, the determination of miRNAs...) |

La expresión de miRNAs en la solución de preservación y sangre en un modelo clínico de donantes subóptimos que incluyan donantes con criterios expandidos o en asistolia, pueden ser biomarcadores que permitan evaluar la viabilidad del órgano durante su preservación previa al trasplante renal, identificar la evolución del daño renal isquémico y predecir el desarrollo de función retrasada del injerto post-trasplante o de un injerto nunca funcionante. Así, la determinación de miRNAs en líquidos de perfusión podría utilizarse, junto a otros indicadores, como criterio de selección de un injerto renal previo a su trasplante. Adicionalmente la expresión de miRNAs y el conocimiento de los mecanismos moleculares de isquemia-reperfusión podrían tener como resultado la modificación dirigida de la composición de la soluciones de preservación. Para ello proponemos 2 modelos de desarrollo paralelo: Un modelo clínico de trasplante de donantes subóptimos en el que se llevaría a cabo la determinación de miRNAs a lo largo de la secuencia de lesión isquémica y un modelo experimental de auto-trasplante de determinación de biomarcadores de viabilidad durante la preservación hipotérmica en máquina con o sin oxigenación del circuito. Los miRNAs se identificarán mediante arrays de qRT-PCR en suero, se seleccionará una combinación y se validará dicha combinación mediante qRT-PCR individualizadas en una cohorte mayor de individuos (Spanish)

The expression of miRNAs in the preservation solution and blood in a clinical model of suboptimal donors that include donors with expanded criteria or in asystolia, can be biomarkers that allow assessing the viability of the organ during its preservation prior to renal transplantation, identifying the evolution of ischemic renal damage and predicting the development of delayed post-transplant or graft function. Thus, the determination of miRNAs in infusion fluids could be used, along with other indicators, as a criterion for selecting a renal graft prior to transplantation. Additionally, the expression of miRNAs and the knowledge of the molecular mechanisms of ischemia-reperfusion could result in targeted modification of the composition of preservation solutions. For this we propose 2 parallel development models: A clinical model of suboptimal donor transplantation in which the determination of miRNAs along the sequence of ischemic injury and an experimental model of self-transplantation of determination of viability biomarkers during hypothermal preservation in machine with or without oxygenation of the circuit would be carried out. MiRNAs shall be identified by serum qRT-PCR arrays, a combination selected and the combination validated by individual qRT-PCR in a larger cohort of individuals (English)
