Molecular Biological and Moleculargenetic Monitoring of Therapy After Kidney Transplantation

Molecular monitoring is conducted in blood cells, plasma samples, urine samples and/or tissue from recipients after kidney transplantation and donors. In the present study the investigators examine the hypothesis that noninvasive diagnostic molecular monitoring can improve the outcome after transplantation. Routine clinical and laboratory data from serum and urine are evaluated at baseline and after 0-1-2-3-4-12-16-52 weeks and 1-2-3-4-5-6-7-8-9-10 years, after kidney transplantation. Mononuclear cells were obtained from the blood and transcripts of several diagnostic genes (including GATA3 (Trans-acting T-cell-specific transcription factor3), GATA4 (Trans-acting T-cell-specific transcription factor4), GAPDH (Glyceraldehyde 3-phosphate dehydrogenase), TRPC3 (Transient receptor potential cononical type3), TRPC6 (Transient receptor potential cononical type6), granzyme B, perforin, FOXP3 (Forkhead box P3), ISG15 (Interferon-stimulated gene 15), Mx1 (Interferon-induced GTP-binding protein), MMP3 (Matrix metalloproteinase-3), MMP9 (Matrix metalloproteinase-9), long-non-coding RNA, and others) are quantified using standard quantitative RT-PCR (Reverse transcription polymerase chain reaction) techniques. Proteomic analysis were performed in plasma and urine samples. Polymorphisms of selected genes are analyzed using standard techniques.
