RAS Inhibition Attenuates Urine Angiotensin II-Regulated Proteins Associated with Interstitial Fibrosis and Tubular Atrophy in Kidney Transplant Recipients.
Angiotensin-II (AngII), the main effector of the renin-angiotensin system (RAS), can lead to interstitial fibrosis/ tubular atrophy (IFTA) in kidney transplant recipients, mainly through AT-1R…2017 American Transplant Congress
TGF-β1 Induces Transplant Kidney Interstitial Fibrosis Through Endothelial-to-Mesenchymal Transition via TGF-β/Smad and Akt/mTOR/p70S6K Pathways.
Urology, The First Affiliated Hospital of Nanjing Medical University, Nanjing, Jiangsu, China
Background: Chronic allograft dysfunction (CAD) induced by kidney interstitial fibrosis is the main cause of allograft failure in kidney transplantation. Studies suggested that endothelial-to-mesenchymal transition…2017 American Transplant Congress
Mechanisms of Fibrosis in the Allograft Kidney: RNA-seq Based Analysis Using Formalin Fixed Biopsies.
Development of allograft fibrosis determines long term graft survival but our understanding of this important complication is incomplete. To gain further insight into this problem…2017 American Transplant Congress
Impact of Antihypertensive (AHT) Choice and Advagraf® Dose on Interstitial Fibrosis/Tubular Atrophy (IF/TA) and IF/TA Progression in Renal Allografts 24 Months Post-Transplantation (Tx).
IF/TA may be delayed using ACEi- or ARB-type AHTs, which target the renin-angiotensin system (RAS), as well as by optimizing tacrolimus (TAC) exposure. The effect…2017 American Transplant Congress
Vimentin Regulates ß-Catenin Translocation During Epithelial to Mesenchymal Transition in Renal Fibrosis.
Sugery, Section of Transplantation, Albany Medical Center, Albany, NY
Introduction: Most renal transplants ultimately fail secondary to chronic allograft nephropathy (CAN). The development of Epithelial to Mesenchymal Transition (EMT) in renal tubular epithelial cells…2017 American Transplant Congress
Genomic Analysis of Gene Expression in Human Kidney Transplants Identifies Moxd1 as a Key Driver for Renal Fibrosis.
Chronic allograft injury (CAI), characterized histologically by high chronic allograft dysfunction index (CADI) score on biopsy, is known to be a major determinant of graft…2017 American Transplant Congress
DNA Hypermethylation Caused by Ischemia in Kidney Transplants Predicts Future Chronic Injury to the Allograft.
Study Purpose: DNA demethylation results from hydroxymethylation and is inhibited by hypoxia. We investigated whether ischemia during kidney transplantation induces DNA methylation changes of the…2017 American Transplant Congress
Circulating Donor-Specific Anti-HLA Antibodies Accelerate the Progression of Interstitial Fibrosis in Kidney Allografts.
Paris Translational Research Center for Organ Transplantation, Paris, France
Interstitial fibrosis represents a major cause of kidney allograft failure. Addressing the causes of accelerated ageing of kidney allografts represents an important challenge to improve…2017 American Transplant Congress
Digital Image Analysis of Pediatric Liver Allograft Biopsies Correlates with METAVIR Fibrosis Score.
1Children's Mercy Hospital, Kansas City, MO; 2University of Kansas Medical Center, Kansas City, KS
Background: Serial surveillance biopsies demonstrate post-transplant inflammation and fibrosis in long-surviving pediatric liver allografts. These changes can ultimately lead to cirrhosis and graft failure. However,…2017 American Transplant Congress
Epigenetic Modifications in the Progression to Chronic Renal Allograft Injury.
1UVA, Charlottesville; 2VCU, Richmond; 3OSU, Columbus; 4NWU, Chicago
Background: The renal allograft is exposed to a milieu of environmental/metabolic stimuli that trigger epigenetic modifications and thereby gene expression patterns which influence function and…
