A comparative kidney transcriptome analysis of bicarbonate-loaded insrr-null mice

Project description:The maintenance of physiological pH level is critical for the life of all organisms. Well known, that kidney is key organ for acid-base regulation in vertebrates. Metabolic alkalosis is the most common acid-base disorder in hospitalized patients, particularly in the surgical critical care unit. The receptor tyrosine kinase IRR (insulin receptor-related receptor), a receptor like the insulin receptor, is involved in acid-base regulation by kidney due to its ability to autophosphorylate under alkalization of extracellular medium (pH > 7.9). IRR expressed in only β-intercalated cells. In mice with a knockout of the insrr gene, which encoding IRR, bicarbonate secretion to the urine is impaired. Here for the first time, we present analysis of kidney transcriptomes from wild type and insrr gene knockout mice under basal or bicarbonate-loaded conditions by 250 mM NaHCO3 in drinking water. Analysis of NGS sequencing data revealed changes in the expression of a number of genes in the kidney. Using real-time PCR we confirmed change of expression of the slc51b, slc26a4, rps7, slc5a2, aqp6, plcd1, gapdh, rny3, lypd2, kcnk5, slc6a6 , atp6v1g3 genes in IRR knockout mice. Also, we found that expression of kcnk5 gene is increased in wild type mice after bicarbonate loading but didn’t change in knockout mice. Gene set enrichment between the IRR knockout and wildtype samples identified that knockout causes alterations in expression of genes related mostly to the ATP metabolic and electron transport chain processes. Thus, for the first time, we described some details of the functioning of the IRR in the kidneys.

Gestational high salt stressed Embryonic Day 14.5 BdkrB2 Null Mouse Kidney vs. BdkrB2 Wild Type Mouse Kidney

Project description:Transcriptional profiling of Embryonic Day 14.5 mouse kidneys comparing the infuence of gestational high salt stress on gene expression remolding of BdkrB2 receptor null mice with that of BdkrB2 receptor wild type mice. 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 renal gene expression pattern. Two-condition experiment, BdkrB2 null mouse kidney vs. BdkrB2 WT mosue kidney with both on gestational high salt stress . Biological replicates: 3 BdkrB2 null/WT replicates, 3 BdkrB2 WT/null replicates, all 6 replicates were duplicated.

S6K1 Phosphoproteome in Tsc1-null mouse kidney iMCD3 cells

Project description:Loss of Tsc1 in the kidneys gives rise to rapid polycystogenesis and kidney failure due to the hyperactivation of mTOR complex I (mTORC1). One of the major downstream targets of mTORC1 is S6K1, which is responsible for driving many of the effector functions of mTOR. Strikingly, the loss of S6k1 in the context of hyperactivated mTOR is sufficient to reverse the generation of polycystic kidneys. In an effort to uncover novel direct S6k1 substrates involved in the generation of cystic kidneys, we generated Tsc1-null and Tsc1/S6k1-double null murine inner medullary collecting duct (iMCD3) cell lines using CRISPR/Cas9. Using these two cell lines, we conducted a phosphoproteome screen to search for novel candidates. Using a combination of antibody-motif enrichment and metal affinity enrichment, we provide a comprehensive phosphoproteome profile between these two genotypes.

Complete embryonic metanephric kidney analysis of wild type and Hoxa11, Hoxd11 null targeted mice

Project description:Complete (whole) embryonic kidneys were dissected from wild type and Hoxa11, Hoxd11 compound null embryons throughout development. Targets from two biological replicates of each were generated and the expression profiles were determined using Affymetrix MOE430A and MOE430B arrays. Comparisons between normal and mutant and comparisons of development samples identified global patterns of gene regulation in kidney development Keywords: embryonic metanephric kidney, kidney development, Hoxa11, Hoxd11, compound null targeted mice

Complete embryonic E11.5 metanephric kidney analysis of wild type and Hoxa11, Hoxd11 null targeted mice

Project description:E11.5 metanephric mesenchyme and ureteric bud were dissected from the E11.5 kidney rudiment using fine manual microdissection (ureteric bud only) or both fine manual microdissection and laser capture microdissection (metanephric mesenchyme) to define the gene expression profiles of these structures. Additionally, HoxA11, HoxD11 compound null E11.5 metanephric mesenchyme was obtained through laser capture microdissection allowing analysis of possible Hox targets in kidney development. Targets from multiple biological replicates of each were generated and the expression profiles were determined using Affymetrix MOE430_v2 arrays.

transcriptional profiling of kidney of PPARgamma null and AZIP mice

Project description:PPARgamma null (PpargΔ/Δ) mice and AZIP mice present a generalized lipodystrophy, accompanied by strong hyperlipidemia and hyperglycemia. Both mouse model develop progressive nephropathy. To shed ligh on the molecular mechanisms underlying the early kidney damage induced by lipodystrophy, we used microarrays to detail the global program of gene expression in whole kidney of PpargΔ/Δ mice and AZIP mice with their respective control mice at 3 weeks of age.
