Project description:Analysis of expression changes in renal collecting duct epithelial cells by adenoviral mediated Krüppel like transcription factor 5 (KLF5) overexpression. KLF5 is a key regulator of static and inflammatory stage in renal collecting duct epithelial cells. We thought these results provide insights into downstream genes of KLF5 in renal collecting duct epithelial cells.
Project description:Analysis of expression changes in renal collecting duct epithelial cells by adenoviral mediated Krüppel like transcription factor 5 (KLF5) overexpression. KLF5 is a key regulator of static and inflammatory stage in renal collecting duct epithelial cells. We thought these results provide insights into downstream genes of KLF5 in renal collecting duct epithelial cells. Total RNAs were isolated from adenovirally-mediated KLF5 over expressed cultured mIMCD-3 cells or control adenovirus infected mIMCD-3. We analyzed these two gene expression profiles after 24 hours after infection.
Project description:Vasopressin is the major hormone that regulates renal water excretion. It does so by binding to a receptor in renal collecting duct cells, triggering signaling pathways that ultimately regulate the abundance, location, and activity of the water channel protein aquaporin 2. We took an advantage of quantitative large scale proteomic technologies and oligonucleotide microarrays to quantify steady state changes in protein and transcript abundances in response to vasopressin in a collecting duct cell line, mpkCCD clone 11 (Yu et al. PNAS 2009, 106:2441-2446). This cell line originally developed by Alan Vandewalle’s group recapitulates vasopressin-mediated AQP2 expression and phosphorylation as seen in native colleting duct cells.
Project description:Transcriptional profiling of new born mouse kidney collecting duct (CD) cells comparing the infuence of gestational high salt stress on gene expression remolding of BdkrB2 receptor knockout CD cells with that of BdkrB2 receptor wild type CD cells. The BdkrB2 receptor has been shown to be playing a role in renal vascular tone, kidney secretion and reabsorption function, normal kidney development, while impaired BdkrB2 receptor in kidney shown being associated with renal agenesis and renal dysplasia. Goal was to determine the effects of BdkrB2 receptor knockout together with gestational high salt stress on collecting duct gene expression pattern.
Project description:We would like to know the gene expression pattern in absence of transcription factor GATA2 in adult renal collecting duct We used Gata2 flox::Pax8-rtTA::Tet-Cre to make a doxycycline induced Gata2 renal tubule cell specific knockout mice We performed microarray analyses using DBA-lectin and magnetic beads purifed collecting duct cells from WT (n=3) or Gata2 CKO mice (n=3) at 4-weeks after doxycycline induction

Goal was to determine the effects of BdkrB2 receptor knockout together with gestational high salt stress on collecting duct gene expression pattern. Single color microarray experiment, BdkrB2 knockout new born mouse CD cells vs. BdkrB2 WT mosue CD cells with both on gestational high salt stress. Biological replicates: 3 BdkrB2 null replicates, 3 BdkrB2 WT replicates. Expression level of each sample was normalized to WT1 replicate.
