Title	Transplant Model Ischemic Conditioning Causes Tissue Leakage and Suppressed Inflammation in a Porcine Kidney
Description	Background: Remote Ischemic Conditioning (RIC) has been proposed as a therapeutic intervention to circumvent the Ischemia/reperfusion injury (IRI) that is inherent to organ transplantation. Using a porcine kidney transplant model, we aimed to decipher the subclinical molecular effects of a RIC regime, compared to non-RIC controls. Methods: Kidney pairs (n = 8+8) were extracted from brain dead donor pigs and transplanted in juvenile recipient pigs following a period of cold ischemia. One kidney in each pair was subjected to RIC prior to reperfusion, while the other served as non-RIC control. We designed an advanced integrative -Omics strategy combining transcriptomics, proteomics, and phosphoproteomics to deduce molecular signatures in kidney tissue that could be attributed to RIC. Results: In kidney grafts taken out 10 h after transplantation we detected minimal molecular perturbations following RIC compared to non-RIC at the transcriptome level, but more pronounced effects at the proteome level. In particular, we noted that RIC resulted in response suppression of tissue inflammatory profiles. Furthermore, an accumulation of muscle extracellular matrix assembly proteins in RIC tissues was detected at the protein level, which may result in response to muscle tissue damage and/or fibrosis. Conclusions: Our data identifies subtle molecular phenotypes in porcine kidneys subjected to RIC which could aid further optimisation of remote ischaemia protocols in renal transplantation.
