    Down-Regulated of Circulating miR-29b, miR-185 and NR_073415.2 in Post-Transplanted Patients with Cytomegalovirus Infection May Serve as Novel Biomarkers for Early Diagnosis.

    A. Yang, W. Ju, Z. Guo, C. Wu, J. Lin, M. Chen, R. Deng, E. Chen, Y. Gao, X. Zhu, X. He.

    Organ Transplantation Center, The First Affiliated Hospital of Sun Yat-sen University, Guangzhou, Guangdong, China.

    Aims: Mortality of CMV infection in post-transplanted patients was quite high, which severely influencing the long-term survival of recipients. For giving them early treatment and…

    IgM Treatment Successfully Prevents Type 1 Diabetes by Dysregulation of Pancreatic MicroRNAs with Immunomodulatory Roles.

    P. Chhabra, R. Gehrau, V. Mas, D. Bower, D. Maluf, K. Brayman.

    UVA, Charlottesville.

    Type 1 Diabetes (T1D) is hallmarked by beta-cells destruction. We aimed to identify specific pancreatic microRNAs (miRNA) as potential biomarkers for T1D prediction and diagnosis,…

    The First Impressions: A Study in Pre and Post-Implantation Renal Grafts for Early Detection Markers of Delayed Graft Function and Recovery.

    S. Bontha,1 L. Suh,1 P. Dormish,1 R. Gehrau,1 E. Rhone,1 L. Gallon,3 A. King,2 C. Dumur,2 D. Maluf,1 V. Mas.1

    1UVA, Charlottesville; 2VCU, Charlottesville; 3Northwestern University, Chicago.

    Background: Delayed graft function (DGF) is mainly a consequence of ischemia and reperfusion injury (IRI) resulting in acute tubular necrosis. The degree of IRI is…

    Urinary Cell-Free DNA Is a Sensitive Marker of Early Renal Transplant Injury

    T. Sigdel, T. Tran, S.-C. Hsieh, M. Sarwal.

    Surgery, UC San Francisco, San Francisco, CA.

    Introduction:Circulating donor-derived cell-free DNA (dd-cfDNA) has been reported as a surrogate of transplant injury in the blood but requires expensive donor and recipient DNA sequencing.Method:…

    Biomarker for Calcineurin Inhibitors Nephrotoxicity in Solid Organ Transplantation: Validation of a Urine Gene Expression Panel

    D. Maluf, R. Gehrau, J. Suh, K. Brayman, C. Bustamante, M. Edmunds, P. Darvishi, V. Mas.

    UVA, Charlottesville, VA.

    Background: We previously described a gene expression signature as biomarker of calcineurin inhibitor nephrotoxicity (CNIT) post renal transplantation. Herein, we aimed to validate the same…

    Early Detection of HCC Mutations in Indeterminate Lesions Using Liquid Biopsies

    Y. Lin,1 K. Cavaness,2 Z. Zhang,1 S. Lin,3 K. Korenblat,1 G. Klintmalm,2 W. Chapman.1

    1Washington University, St. Louis, MO; 2Baylor University, Dallas, TX; 3Stanford University, Palo Alto, CA.

    Background Recent sequencing efforts have characterized the mutation profile of hepatocellular carcinoma (HCC); however, the relevance to clinical decision-making has been limited by the infrequency…

    Validation of a Peripheral Blood Gene Expression Profile for SubClinical Acute Rejection in Kidney Transplant Recipients – Findings from the CTOT 08 Study

    J. Friedewald,1 S. Kurian,2 T. Gelbart,2 D. Salomon,2 M. Abecassis.1

    1Northwestern University, Chicago; 2Scripps Research Institute, La Jolla.

    Background: Sub-clinical acute rejection (SCAR) is histologic acute cellular rejection in the presence of a normal/stable serum creatinine, and is associated with worse graft survival.…

    Non-Invasive Panel of MicroRNAs Predict Long-Term Outcomes Post-Kidney Transplantation

    J. Suh,1 D. Maluf,1 H. Cathro,2 R. Gehrau,1 I. McConnell,1 K. Brayman,1 C. Dumur,2 V. Mas.1

    1Surgery and Pathology, UVA, Charlottesville, VA; 2VCU, Richmond, VA.

    Background. Currently available methods for evaluating kidney graft function post-transplantation (KT) are either ineffective or inaccurate (e.g., serum creatinine) or highly invasive (e.g., biopsies). We…
