Project description:The affect of aldosterone on the miRNA landscape in mIMCD-3 cells was determined In the study presented here, the affect of aldosterone was examined on the miRNA content in a murine inner medullary collecting duct cell line
Project description:miRNA plays a role as post-transcriptional regulator. However, miRNAs in the kidney collecting duct cell have not been well understood. So we aimed to profile miRNAs in the kidney inner medullary collecting duct (IMCD) cells, and to identify the vasopressin-responsive miRNAs in the kidney IMCD cells. The microarray assay revealed that relative expression of miRNAs in the kidney IMCD cells was changed by desmopressin (dDAVP) stimulation.
Project description: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)

The microarray assay revealed that relative expression of miRNAs in the kidney IMCD cells was changed by desmopressin (dDAVP) stimulation. Fresh IMCD tubules were prepared from rat kidney and incubated in the medium in the absence or presence of dDAVP (1 nM, 2 h). Total RNA purified from IMCD tubules was used to analyze miRNA expression by GeneChipM-BM-. miRNA 3.0 Array (Affymetrix).

Project description:Purpose: The goal of this study is to identify doxycycle-responsive genes in mouse kidney inner medullary collecting duct cell line mIMCD3. To explore compreshensive profile of doxycycline-mediated gene expression, transcriptomes of doxycycline-responsive genes at two different time points (3 days and 6 days) were profiled and analyzed. Methods: Total RNAs were isolated from mIMCD3 cells treated with doxycycline or vehicle at different time points (3 days and 6 days). Four replicates for vehicle- or doxycycline-treated group were generated at each tested time point. cDNA libraries were prepared using a Nextera DNA library preparation protocol. The sequence reads from Illumina HiSeq3000 platform were qualified and quantified at the transcript level using Salmon (0.14.1). Differential expression analysis were performed using edgeR. Results: mRNA profiles of mouse kidney inner medullary collecting duct mIMCD3 cells treated with doxycycline or vehicle (DMSO) for 3 days and 6 days were generated using an optimized RNA-Seq workflow. Transcript level quantification using a pseudo-alignment quantification method (Salmon) was performed to calculate transcript abundance in each sample. Then differential expression analysis identified the differentially expressed genes at each time point comparison (DOX vs vehicle). Conclusions: This study revealed comprehensive transcriptomic changes of doxycycline-responsive gene expression in mouse kidney inner medullary collecting duct cells.
Project description:All-trans retinoic acid (tRA) is the bioactive derivative of vitamin A that regulates gene expression by activating RA receptors (RAR). By using a reporter mouse model, we recently showed that endogenous tRA/RAR signaling was present in kidney collecting duct cells, and in mouse inner medullary collecting duct cell line (mIMCD-3). In order to unveil target genes of endogenous tRA/RAR signaling in kidney collecting duct cells, whole genome microarray analysis was performed on mIMCD-3 cells treated with AGN193109, a pan-RAR antagonist, and 4-diethylaminobenzaldehyde (DEAB), an inhibitor of tRA synthesizing enzyme. Specificity of gene expression regulation was confirmed by determining the reversibility of the regulation by simultaneous addition of exogenous tRA.
