Project description:A total of 35 samples of renal tissues (15 DN, 10 DM, and 10 CON) were selected randomly from archived deidentified formalin-fixed paraffin-embedded DN biopsy tissue specimens. Normal control kidney tissues were obtained from kidneys that had been refused for use in transplantation due to vascular anomalies or from preimplant biopsy samples. Three random samples from each group were used for lncRNA microarrays
Project description:In order to find out the different expression of miRNA in DKD patients and controls, the kidney tissues of DKD and controls were used to do the miRNA mircroassy.
Project description:We identified 1,700 differentially expressed probesets in DKD glomeruli and 1,831 in diabetic tubuli; 330 probesets were commonly differentially expressed in both compartments. The canonical complement signaling pathway was determined to be statistically differentially regulated in both DKD glomeruli and tubuli and was associated with increased glomerulosclerosis even in an additional set of DKD samples. Affymetrix expression arrays were used to identify differentially regulated transcripts in 44 microdissected human kidney samples. Stringent statistical analysis using the Benjamini_Hochberg corrected 2-tailed t-test was used to identify differentially expressed transcripts in control and diseased glomeruli and tubuli. This Series includes DKD and control glomeruli samples.

Project description:In order to explore the role of circRNA in diabetic kidney disease (DKD), we employed circRNAs microarray expression profile in the plasma of daibetes patients (n=6), diabetic kidney disease patients (n=6) and healthy controls (n=6). According to the microarray data, we found 2079 differentially expressed circRNA in the plasma of DKD patients compared to the healthy people, including 1182 up-regulated and 897 down-regulated.Among the differentially expressed circRNA, nine DKD-related circRNAs were chosen and further validated by qRT-PCR.The results revealed that circUBXN7 was significantly elevated in the plasma of DKD patients, and might be a diagnostic plasma marker for DKD.
Project description:Diabetic kidney disease (DKD), a progressive kidney disease, is a major complication associated with diabetes and has become the leading cause of chronic kidney disease in China. Increasing evidences have demonstrated that lncRNAs play vital roles in kidney diseases, including DKD. To search for new ncRNAs involved in DKD, we performed gene expression profiling in the kidney tissues isolated from DKD patients and non-diabetic renal cancer patients undergoing surgical resection by RNA sequencing. And we identified 65 DEncRNAs (29 upregulated and 36 downregulated in DKD) and 171 DEmRNAs (72 upregulated and 99 downregulated in DKD).This study will provide insights into the prevent and treatment of DKD in the future.

Project description:Analysis of gene expression changes in differentiated human podocytes treated with the serum from patients with (DKD+) or without (DKD-) diabetic kidney disease when compared to normal subjects (C). The hypothesis is that the three groups can be distinghed by their differential gene expression pattern. The results obtained revealed important information regarding differences in gene expression in human podocytes treated with the serum from patients with (DKD+) or without (DKD-) diabetic kidney disease when compared to normal subjects (C). Human podocytes were contacted with the serum from patients with diabetes and kidney disease (DKD+) or without kidney disease (DKD-) and compared to normal human podocytes contacted with serum from patients without diabetes (C).
