Renal and circulating non-coding RNAs in transplantation. Multiple studies have described molecular signatures of ncRNAs, as well as individual miRNAs, lncRNAs and circRNAs associated with disease states post-transplantation. Their study could lead to improved diagnosis of transplantation outcomes while simultaneously offering an insight into the pathogenesis of renal disease often developed in these patients. miRNA, microRNA; lncRNA, long non-coding RNA; circRNA, circular RNA; DGF, delayed graft function; AKI, acute kidney injury; AR, acute rejection; TCMR, T-cell-mediated rejection; CAD, chronic allograft dysfunction; IF/TA, interstitial fibrosis and tubular atrophy; ABMR, antibody-mediated rejection; DSA, donor specific antibodies.
