ERRγ coordinates a transcriptional program of mitochondrial and renal reabsorptive functions implicated in kidney disease [RNA-seq]

ABSTRACT: Here we show that estrogen-related receptor γ (ERRγ) is an essential transcriptional coordinator of both renal mitochondrial and reabsorptive functions. ERRγ is highly and specifically expressed in the RECs, and its expression correlates with kidney function in humans. We generated REC-ERRγ KO mice which developed severe renal mitochondrial and reabsorptive dysfunction and fluid-filled cysts. Transcriptome and cistrome analysis revealed that ERRγ directly regulates mitochondrial metabolism and renal reabsorption. ChIP-reChIP-Seq studies further suggest that ERRγ employs a distinct mechanism to regulate renal reabsorption genes through functional cooperation with hepatic nuclear factor 1 beta (HNF1β), mutations of which cause strikingly similar renal dysfunction and cysts in humans and animals. Together these findings reveal a novel role for ERRγ in simultaneously coordinating a transcriptional program for renal energy production via mitochondria and energy consumption to perform reabsorptive functions required for normal kidney function

Transcription factor hepatocyte nuclear factor 1β controls a transcriptional network regulating cell polarity in kidney cells

Project description:Mutations or deletions in HNF1β cause autosomal dominant tubulointerstitial kidney disease (ADTKD)-HNF1β, a rare and heterogenous disease characterized by renal cysts and/or malformation, maturity-onset diabetes of the young, hypomagnesemia, hypokalemia and hypocalciuria. The electrolyte disturbances may develop in the distal part of the nephron, which is important for finetuning of Mg2+, Ca2+, K+ reabsorption. Moreover, this segment is a prevalent site of cyst formation in ADTKD-HNF1β patients. Therefore, we aim to study the transcriptional network directed by HNF1β in the distal part of the nephron. For this we combined HNF1β ChIP-seq and mRNA expression data to identify direct targets of HNF1β in a renal distal convoluted tubule cell line (mpkDCT).

ERRγ links adaptive neuronal metabolism to spatial learning and memory [ChIP-Seq]

Project description:Neurons utilize glucose to generate adenosine triphosphate (ATP) essential for their survival, excitability and synaptic signaling, as well as initiating changes in neuronal structure and function. Defects in oxidative metabolism and mitochondria functions are also associated with aging and diverse human neurological diseases1-4. While neurons are known to adapt their metabolism to meet the increased energy demands of complex behaviors such as learning and memory, the molecular underpinnings regulating this process remain poorly understood4-6. Here we show that the orphan nuclear receptor estrogen related receptor gamma (ERRγ) becomes highly expressed during retinoic-acid induced neurogenesis and is widely expressed in neuronal nuclei throughout the brain. Mechanistically, we show that ERRγ directly orchestrates the expression of networks of genes involved in mitochondrial oxidative phosphorylation and energy generation in neurons. The importance of this regulation is evidenced by decreased adaptive metabolic capacity in cultured neurons lacking ERRγ, and reduced long-term potentiation (LTP) in ERRγ-/- hippocampal slices. Notably, the defect in LTP was rescued by the metabolic intermediate pyruvate, functionally linking the ERRγ knockout metabolic phenotype and memory formation. Consistent with this notion, mice lacking neuronal ERRγ exhibit defects in spatial learning and memory. These findings implicate ERRγ in the metabolic adaptations required for long-term memory formation. We used ChIP-Seq analysis to determine the genome-wide binding of ERRγ in neurons derived from ES cells.

ERRγ links adaptive neuronal metabolism to spatial learning and memory [Array data]

We used microarray analysis to compare the genome-wide gene expression changes between wild type (WT) and ERRγ-/- P0 cerebral cortex as it contains mainly neuronal lineage at this stage compared to adult cortex.

Candidate genes mediated by estrogen-related receptor gamma (ERRγ) in pancreatic β cells

Project description:Recent studies have established the importance of ERRγ as a required participant for insulin secretion in pancreatic β cells. Key downstream genes of ERRγ remain unclear in the pancreatic β cell. To understand the molecular role of ERRγ and elucidate potential key candidate genes involved in pancreatic β cells, the eukaryotic expression plasmid containing mouse ERRγ was constructed and transfected into NIT-1 pancreatic β cells. Overexpression of ERRγ was confirmed by Q-RT-PCR and western blot. RNA-seq was conducted to get the gene expression profiling between the experimental cells and control cells. Differentially expressed genes (DEGs) were identified and subsequently analyzed by gene ontology (GO) enrichment analysis and kyoto encyclopedia of genes and genomes (KEGG) pathway enrichment analysis. We found that overexpression of ERRγ in pancreatic β cells enables regulation of the expression of certain genes involved in cell apoptosis and mitochondrial function, such as TFPT, Bcl7c, Dap, Thoc6, Ube2d3, ATP5H, MPV17, and NDUFA6. GO analysis revealed that the DEGs were mainly enriched in biological regulation, cell, and binding. KEGG pathway analysis demonstrated that DEGs were significantly enriched in infectious diseases, translation annd signal transduction. This study helps to further understand and reposition the molecular mechanisms of ERRγ in pancreatic β cells.

Activation of ERRγ enhances mitochondrial and sarcomere maturation in human induced pluripotent stem cell-derived cardiomyocytes

Project description:We identified two cardiac maturation stimulators from 9,048 compounds using Troponin I1 (TNNI1) and Troponin I3 (TNNI3) double reporter hiPSC-derived CMs. An estrogen-related receptor gamma (ERRγ)-specific agonist increased the size of hiPSC-CMs and their mitochondrial content and enhanced their mitochondrial function. In addition, combination of this agonist with an inhibitor of S-phase kinase-associated protein 2 (SKP2) increased the TNNI3 expression more highly than previous methods and enhanced cardiac maturation-related gene expression profiles.

ERRγ mediates Tamoxifen resistance in novel models of invasive lobular breast cancer

Project description:One-third of all ER+ breast tumors treated with endocrine therapy fail to respond, and the remainder are likely to relapse in the future. Almost all data on endocrine resistance has been obtained in models of invasive ductal carcinoma (IDC). However, invasive lobular carcinomas (ILC) comprise up to 15% of newly diagnosed invasive breast cancers diagnosed each year and, while the incidence of IDC has remained relatively constant during the last 20 years, the prevalence of ILC continues to increase among postmenopausal women. We report a new model of Tamoxifen (TAM)-resistant invasive lobular breast carcinoma cells that provides novel insights into the molecular mechanisms of endocrine resistance. SUM44 cells express ER and are sensitive to the growth inhibitory effects of antiestrogens. Selection for resistance to 4-hydroxytamoxifen led to the development of the SUM44/LCCTam cell line, which exhibits decreased expression of estrogen receptor alpha (ERα) and increased expression of the estrogen-related receptor gamma (ERRγ). Knockdown of ERRγ in SUM44/LCCTam cells by siRNA restores TAM sensitivity, and overexpression of ERRγ blocks the growth-inhibitory effects of TAM in SUM44 and MDA-MB-134 VI lobular breast cancer cells. ERRγ-driven transcription is also increased in SUM44/LCCTam, and inhibition of activator protein 1 (AP1) can restore or enhance TAM sensitivity. These data support a role for ERRγ/AP1 signaling in the development of TAM resistance, and suggest that expression of ERRγ may be a marker of poor Tamoxifen response.
