Use of Ancestral Genetic SNP Phenotyping to Define Genotypic Ethnicity in Solid Organ Transplant Patients
Surgery, Baylor College of Medicine, Houston, TX
*Purpose: Transplantation research has mainly categorized ethnicity into four main groups African American, Caucasian, Hispanic, and Asian Pacific Islander. Our world has increased in admixure…2022 American Transplant Congress
A Three-gene Peripheral Blood Potential Diagnosis Signature Associated With Autophagy For Antibody-mediated Rejection In Renal Transplantation
Department of Urology, Beijing Chao-Yang Hospital, Capital Medical University, Beijing, China
*Purpose: Antibody-mediated rejection (AMR) is emerging as a major cause of graft loss in renal transplantation. Nowadays, non-invasive diagnosis of AMR with high accuracy is…2022 American Transplant Congress
RNA Sequencing Profiling of Pretransplant Blood Identified Variant Allele Specific Expression of Leukocyte Immunoglobulin-Like Receptors (LILRs) Genes Associated with Graft Loss in Kidney Transplant Recipients
*Purpose: The RNA sequencing has the possibility of detecting overall gene expression as well as allele-specific expression. Here, we reported a study of genome-wide allele…2022 American Transplant Congress
The Role Of Combined Gene Expression Profiling And Donor-derived Cell-free Dna In Differentiating Acute Rejection In Liver Transplant Recipients
*Purpose: In our previous studies, blood-based gene expression profiling (GEP) and donor-derived cell-free DNA (dd-cfDNA) have been independently validated in liver transplant recipients (LTR) to…2022 American Transplant Congress
Induction of Tacrolimus Clearance by Steroids Varies by Cyp3a5 Genotype in Kidney Transplant Recipients: A Drug-Drug-Gene Interaction
*Purpose: Tacrolimus (TAC) is the primary immunosuppressant used in organ transplantation. TAC is a substrate for CYP3A4/5. These enzymes are inhibited or induced by multiple…2022 American Transplant Congress
A Novel Approach to Non-Invasive Multimodality Testing with Allosure and Allomap Predicts Microvascular Inflammation with High Accuracy in Kidney Transplant Recipients
University of Wisconsin, Madison, WI
*Purpose: The most prominent histologic lesion in antibody-mediated rejection (ABMR) is microvascular inflammation (MVI); however, its recognition and scoring can be challenging and poorly reproducible…2022 American Transplant Congress
RBBP7 as a Novel Biomarker for the Molecular Diagnosis of BK Virus-Associated Nephropathy
Department of Urology, Beijing Chaoyang Hospital, Beijing, China
*Purpose: BK virus-associated nephropathy (BKVN) remains a major infectious complication of kidney transplantation, and its histologic appearance can mimic rejection, leading to a diagnostic dilemma…2022 American Transplant Congress
The Prediction of Renal Allograft Rejection by Time-Dependent Two-Signature Predictors
*Purpose: The study aims to develop RNA signature predictors using preemptive biopsy transcriptome data to predict future allograft rejection and reveal the predictors' time-dependent features.*Methods:…2022 American Transplant Congress
Comparative Analysis of kSORT Assay for Predicting Acute Renal Allograft Rejection Under Belatacept-Based Immunosuppression
*Purpose: The kSORT (Kidney Solid Organ Response Test) assay uses transcriptomic profiling of peripheral blood to predict the presence of acute rejection (AR) in renal…2022 American Transplant Congress
Donor-Derived Cell-Free DNA Trends Before and After Rejection Vary Based on Timing of Rejection
1Northwestern University, Chicago, IL, 2Transplant Nephrology, Northwestern University, Chicago, IL
*Purpose: Donor-derived cell-free DNA (dd-cfDNA) has been used for acute rejection detection and trending levels may help predict future rejection and assess the adequacy of…
