| Title |
Renal medulla miRNA expression of hypertensive, m42D miR |
| Sample type |
RNA |
| |
|
| Source name |
Renal medulla of hypertensive male
|
| Organism |
Homo sapiens |
| Characteristics |
gender: male
tissue: renal medulla
blood pressure: hypertensive
|
| Treatment protocol |
Tissue was transferred into containers with RNAlater (Ambion) and preserved at 70°C before mRNA extraction.
|
| Growth protocol |
Approximately 1 cm3 of tissue from the healthy (unaffected by cancer) pole of the kidney was obtained immediately after surgery.
|
| Extracted molecule |
total RNA |
| Extraction protocol |
The RNeasy kit (Qiagen) was used for extraction of total RNA according to the manufacturer's instructions. Medulla and cortex were separated and individual RNA was obtained for each of them.
|
| Label |
Cy3
|
| Label protocol |
100ng of total RNA was prepared for hybridization according to the standard Agilent protocol (microRNA Labeling & Hybridization Kit Manual, Agilent, Version 1.7, October 2009).
|
| |
|
| Hybridization protocol |
After fragmentation, samples were hybridized to Agilent Human miRNA Microarrays (V3, release 12.0) for 20 hr at 55°C. Chips were washed and stained in the Agilent Microarray Hybridization Chamber SureHyb. The Agilent’s miRNA Complete Labeling and Hyb Kit was used according to Agilent's manual.
|
| Scan protocol |
The chips were scanned on an Agilent G2565BA scanner.
|
| Description |
miRNA expression from male hypertensive patient.
|
| Data processing |
The samples were between-array normalized so that expression intensities were similar across all arrays using the quantile method, in the R application (version 2.11.1). Differentially expressed miRNAs were identified using the moderated two-sample t-test in the Limma package.
