Project description:Murine inner medullary collecting duct cells were treated for 1 hour with vehicle (control) or aldosterone. Total RNA was isolated and used as template to generate the eventual cRNA target. The experiment was repeated a total of three times. Six cRNA samples, three control and three treated, were generated and used in a total of six hybridizations. The mineralocorticoid aldosterone is a major regulator of Na+ and acid-base balance and control of blood pressure. Although the long-term effects of aldosterone have been extensively studied, the early aldosterone-responsive genes remain largely unknown. Using DNA array technology, we have characterized changes in gene expression after 1 h of exposure to aldosterone in a mouse inner medullary collecting duct cell line, mIMCD-3. Results from three independent microarray experiments revealed that the expression of many transcripts was affected by aldosterone treatment. Northern blot analysis confirmed the upregulation of four distinct transcripts identified by the microarray analysis, namely, the serum and glucose-regulated kinase sgk, connective tissue growth factor, period homolog, and preproendothelin. Immunoblot analysis for preproendothelin demonstrated increased protein expression. Following the levels of the four transcripts over time showed that each had a unique pattern of expression, suggesting that the cellular response to aldosterone is complex. The results presented here represent a novel list of early aldosterone-responsive transcripts and provide new avenues for elucidating the mechanism of acute aldosterone action in the kidney.

Project description:Aldosterone is arguably the single most important hormone implicated in the control of blood pressure and extracellular fluid volume in mammals. It acts primarily by increasing the rate of transepithelial sodium transport in the kidney tubules. Several monogenetic defects resulting in hypertension have now been attributed to abnormalities in sodium handling within the aldosterone-sensitive distal nephron, where the epithelial sodium channel, ENaC, constitutes the rate-limiting step of sodium transport. To date, the transcription-dependent aldosterone-signaling pathway between receptor and membrane transport effectors, remains incompletely understood. The broad aim of our study is to explore these intracellular signaling pathways that are critical to the functioning of sodium channels. Microarray analysis in an aldosterone-responsive kidney cortical collecting duct cell line (mpkCCDc14), allowed us to identify many potential aldosterone-regulated transcripts. The present study describes the identification, and possible physiological relevance of various aldosterone-regulated transcripts. The results of this study promise to extend our understanding of the molecular basis of aldosterone-regulated sodium transport in kidney epithelia, and provide approaches for regulating this process in disease states such as congestive heart failure and hypertension.

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)

Project description:Kidneys are essential for acid-base homeostasis, especially when organisms cope with changes in acid or base dietary intake. Because collecting ducts constitute the final site for regulating urine acid-base balance, we undertook to identify the gene network involved in acid-base transport and regulation in the mouse outer medullary collecting duct (OMCD). For this purpose, we combined kidney functional studies and quantitative analysis of gene expression in OMCDs, by transcriptome and candidate gene approaches, during metabolic acidosis. Furthermore, to better delineate the set of genes concerned with acid-base disturbance, the OMCD transcriptome of acidotic mice was both compared to that of normal mice and mice undergoing an adaptative response through potassium depletion. Metabolic acidosis, achieved through a NH4Cl-supplemented diet for 3 days, not only induced acid secretion, but also stimulated the aldosterone and vasopressin systems and triggered cell proliferation. Accordingly, metabolic acidosis increased the expression of genes involved in acid-base transport, sodium transport, water transport and cell proliferation. In particular, more than 25 transcripts encoding proteins involved in urine acidification (subunits of H-ATPase, kidney anion exchanger, chloride channel Clcka, carbonic anhydrase 2, aldolase) were co-regulated during acidosis. We propose that these trancripts cooperating to a same function and co-regulated during acidosis constitute a functional regulon.

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.
