Transcription profiling of rat inner medullary collecting duct


ABSTRACT: Identification of gene expressed in the enriched inner medullary collecting duct cells in rat. Experiment Overall Design: Rat inner medullary collecting duct (IMCD) cells were isolated from 7 male Sprage-Dawley rats by collagenase and hyaluronidase digestion and follow by low speed centrifugation. The non-IMCD cells were collected by centrifugation of supernatant of enriched IMCD samples. Experiment Overall Design: Total RNA about 3 ug were used per microarray (Rat 230 2.0 Genechip array). Experiment Overall Design: The experiments were repeat 3 times (3 pairs of IMCD VS non-IMCD)

ORGANISM(S): Rattus norvegicus

Vasopressin acts on the inner medullary collecting duct (IMCD) in the kidney to regulate water and urea transport. To obtain a "parts list" of gene products expressed in the IMCD, we carried out mRNA profiling of freshly isolated rat IMCD cells using Affymetrix Rat 230 2.0 microarrays with approximately 31,000 features; 7,913 annotated transcripts were found to be expressed above background in the IMCD cells. We have created a new online database (the "IMCD Transcriptome Database;" http://dir.nh  ...[more]
