Project description:Acute kidney injury (AKI) is an important contributor to the development of chronic kidney disease (CKD). We performed miRNA and mRNA sequencing on biobanked human kidney tissues obtained in the routine clinical care of patients with the diagnoses of AKI and minimal change disease (MCD), in addition to nephrectomized (Ref) tissue from individuals without known kidney disease. From all renal biopsy samples, 2 cryosections (10 μM) including the entire cross-section of the tissue were placed directly into PicoPure RNA extraction buffer. RNA was isolated using the PicoPure isolation kit. Total RNA was evaluated for quantity and quality using an Agilent Bioanalyzer. Approximately 100 ng of total RNA was used for library construction with QIASeq miRNA Library Kit. Each resulting indexed library was quantified and its quality assessed by Qubit and Agilent Bioanalyzer. The libraries were then loaded onto an Illumina NextSeq 500 for 75 bp single-read sequencing to a depth of 15-20M reads per library. Sequence reads were uploaded to the Qiagen GeneGlobe Data Analysis Center (https://www.qiagen.com/us/resources/geneglobe) for quality control, alignment and expression quantification. Reads were mapped to different databases for mature, hairpin, noncoding RNA, mRNA and other RNA using bowtie v1.2. Read counts and UMI counts for each RNA category (mature, hairpin, piRNA, tRNA, rRNA, mRNA and otherRNA) were calculated for each sample, using miRbase V21 for miRNA, and piRNABank for piRNA.

Approximately 10 ng of total RNA were used for each sample’s library preparation. Ribosomal RNA was removed using RiboGone – Mammalian Kit protocol. After rRNA depletion, double-stranded cDNA was synthesized and amplified using the SMARTer Universal Low Input RNA Kit protocol. The cDNA was sheared by Covaris, and the library was prepared and barcoded following the Ion Plus Fragment Library Kit protocol. Each resulting barcoded library was quantified and quality assessed by Agilent Bioanalyzer. Multiple libraries were pooled in equal molarity. Finally, 8 μL of 100 pM pooled libraries were loaded into lanes of an Illumina HiSeq 4000. At least 30M reads per library were generated.

Project description:The goal of this observational study is to compare anesthetic modalities (intravenous propofol anesthesia with sevoflurane gas anesthesia) in patients who underwent colorectal cancer resection surgery regarding the outcome of acute kidney injury.
The main questions it aims to answer are:
* is there a difference in acute kidney injury incidence in the two anesthetic modalities?
* is there a difference in plasma creatinine between the two anesthetic modalities?
* are there any patient characteristics or intraoperative factors that effect the incidence of acute kidney injury in either anesthetic modality?
The study will analyze data from the CAN clinical trial database. (Cancer and Anesthesia: Survival After Radical Surgery - a Comparison Between Propofol or Sevoflurane Anesthesia, NCT01975064)

Project description:Purpose: The pathogenesis of contrast-induced acute kidney injury (CI-AKI) has not yet been clearly understood. miRNAs are important mediators which normally work by post-transcriptional degradation of target mRNAs. Emerging evidence indicated a number of differentially expressed miRNAs in CI-AKI following intravenous contrast medium injection. However, there exist differences in the pathological mechanisms and incidences of CI-AKI between intravenous and intra-arterial contrast administration. We aimed to investigate the critical roles of dysregulated miRNAs and the correlated mRNAs in the kidney injury following intra-arterial contrast exposure. Methods: Based on a reliable CI-AKI rat model, we sought to investigate the roles of miRNA-mRNA interactions in the kidney injury following intra-arterial contrast exposure using the Illumina Genome Analyzer IIx. Results: In the study, 36 differentially expressed mature miRNAs were identified ( fold change > 1.5 and p value < 0.05) in the kidney of CI-AKI rats (n = 3) compared with controls (n = 3), consisting of 23 up-regulated and 13 down-regulated ones. Bioinformatics analysis revealed that Wnt, TGF-β, and AMPK signaling pathways were most likely to be modulated by these dysregulated miRNAs. Around 453 dysregulated genes ( fold change > 2.0 and p value < 0.05) were identified. Integrated analysis revealed 2037 putative miRNA-mRNA pairs with negative correlations. Of which, 6 differential miRNAs and 13 genes were selected for further quantitative real-time polymerase chain reaction validation (n = 6 for each group), and a well correspondence between the 2 techniques was observed. Conclusions: In conclusion, our present study contributes to the first evidence of miRNA-mRNA regulations in the development of kidney injury following an intra-arterial contrast injection route. These novel findings provide insights into the underlying mechanisms of CI-AKI.

Project description:Contrast-induced acute kidney injury (CI-AKI) is typically defined by an increase in serum creatinine (SCr) after intravascular administration of contrast medium. Since creatinine is an unreliable indicator for acute changes in kidney function, an early biomarkers for CI-AKI diagnosis is important for initiating therapy.We assessed the hypothesis that circulating microRNAs (miRNAs) could be served as potential biomarkers to early detect CI-AKI.The rat model of acute kidney injury was developed as we previously described. We first detect miRNA profile of plasma and kidney tissue using Agilent microarray platform. 3 miRNA species with > 1.5-fold increase in plasma samples of CI-AKI rats, including miRNA-30a, miRNA-30e and miRNA-188, were selected as candidate miRNAs of potential biomarkers. 24 rats were randomly divided into 2 groups (CI-AKI group and control group), each with 4 subgroups (n=3). Peripheral blood and kidney samples were harvest at 8h after contrast medium/normal saline administration. Total RNA sample from each rat in the same subgroup was combined together as pooled sample for further test. The Agilent microarray platform was adapted to profile the miRNA spectra.
