title: Molecular dysfunctions in acute rejection after renal transplantation revealed by integrated analysis of transcription factor, microRNA and long noncoding RNA.
abstract: Acute rejection remains a problem in renal transplantation. To further illustrate the mechanism of rejection, we integrated protein array-based proteomics and RNA microarray-based genomics to investigate the transcription factor, microRNA and long noncoding RNA of biopsies of three patients with acute rejections and a control group. 99 transcription factors were identified in acute rejection biopsies compared to normal renal tissue. We correlated transcription factor data with microRNA and long noncoding RNA data sets and reported the expression of 5 transcription factors (AP-1, AP-4, STATx, c-Myc and p53), 12 miRNAs and 32 lncRNAs in acute rejection biopsies. Pathway analysis demonstrated that over-presentation of transcription factor pathway plays a critical role in acute rejection. This is the first study to comprehensively report the acute rejection transcription factor pathway. Integrative analysis of the transcription factor, microRNA and long noncoding RNA provided an expansive view of molecular signaling pathways in acute rejection after renal transplantation.
