Presence of donor- and recipient-derived DNA in cell-free urine samples of renal transplantation recipients: urinary DNA chimerism.
BACKGROUND Previous studies have indicated that microchimerism is present in body tissues, peripheral blood, and plasma of recipients after organ transplantation. We hypothesize that donor-derived DNA may also be present in cell-free urine of renal transplant recipients and that the concentrations of urine DNA may be correlated with graft rejection. METHODS Thirty-one female patients who had ...
متن کاملDonor-Derived Cell-Free DNA Is a Novel Universal Biomarker for Allograft Rejection in Solid Organ Transplantation.
BACKGROUND In solid organ transplantation, sensitive real-time biomarkers to assess the graft health are desirable to enable early intervention, for example, to avoid full-blown rejections. During rejection, high amounts of graft-derived cell-free DNA (GcfDNA) are shed into the blood stream. The quantification of this GcfDNA in allotransplantation is considered to fulfill this need, because it ...
متن کاملBiological Variation of Donor-Derived Cell-Free DNA in Renal Transplant Recipients: Clinical Implications
Background: Previous studies have demonstrated that donor-derived cell-free DNA (dd-cfDNA) found in circulating blood of transplant recipientsmay serve as a noninvasive biomarker of allograft rejection. To better interpret the clinicalmeaning of dd-cfDNA, it is essential to understand the biological variation of this biomarker in stable healthy recipients. This report establishes the biological...
متن کاملcell free dna: a novel biomarker for clinical diagnosis
cell free dnas (cfdnas) are small fragments of genomic or mitochondrial dna releasing from cells into the blood stream. the presence of cfdna in the human circulatory system has been shown for the first time in 1948 however, the potential clinical applications of cfdna remained unknown until recent progress in detection and quantification of these molecules by sensitive methods. in this paper, ...
متن کاملQuantification of transplant-derived circulating cell-free DNA in absence of a donor genotype
Quantification of cell-free DNA (cfDNA) in circulating blood derived from a transplanted organ is a powerful approach to monitoring post-transplant injury. Genome transplant dynamics (GTD) quantifies donor-derived cfDNA (dd-cfDNA) by taking advantage of single-nucleotide polymorphisms (SNPs) distributed across the genome to discriminate donor and recipient DNA molecules. In its current implemen...
