Официальное название

Tissue Analysis (Histological, Ultrastructural and Molecular) of Liver Grafts as a Predictor of Transplant Outcome.

Обзор

Despite the good clinical results in terms of outcome with the application of HOPE prior to liver transplantation, very little is still known about the phenotypic and molecular changes that occur during perfusion/preservation during HOPE, particularly with regard to endothelial trophism and activation. Delving into these aspects would be very useful to allow personalised perfusion treatments in the future, thus improving the outcome of transplantation.

Подробное описание

The primary aim of the study is the identification of specific 'endothelial signatures' (markers on tissue with immunohistochemistry and gene expression with RT-PCR) in liver grafts after HOPE treatment, predictive of transplant outcome. Interventional study without drug, including two cohorts of patients: (1) liver donors, on whom an allocation biopsy for organ quality will be performed (as standard of care); (2) liver recipients (from donors in cohort 1) on whom a study-specific biopsy will be performed as soon as the transplant has taken place (after vascular anastomoses with organ revascularisation). The study-specific biopsy constitutes the intervention of the study; patients will be treated according to the judgement of the physician and the information reported in the Technical Data Sheet of each product of any concomitant therapies administered according to clinical practice.

Вмешательства

Диагностический тест histochemical and immunohistochemical analysis
2 µm sections will be cut from the paraffin blocks for histochemical and immunohistochemical (IHC) investigations. IHC will be performed with an automated stainer (Ventana/Roche®, Ventana Medical Systems, USA) for the endothelial markers CD34, ERG, Nestin and Caveolin-1
Диагностический тест RT-PCR
Custom RT-PCR analyses will be performed manually for the transcripts (mRNA) of the ERG, Nestin, VEGFR and other genes, at the Pathology Anatomy lab hall. 18 (Prof. D'Errico). Total RNA will be extracted from the paraffin blocks with the RecoverAll™ Total Nucleic Acid Isolation kit (Invitrogen). Reverse Transcriptase will be performed with the High Capacity Reverse Transcription kit (Life Technologies), using the specific primers. Real-Time PCR will be performed with the CFX Connect Real-Time PC
