Project description:Treatment for acute kidney injury (AKI) is suboptimal. A better understanding of its pathogenesis may lead to new therapeutic approaches. Kidney transcriptomics analyses of murine folic acid-induced AKI (FA-AKI) identified Runx1 as the most upregulated RUNX family gene. RUNX1 overexpression in FA-AKI was validated at the mRNA and protein levels and localized mainly to tubular cell nuclei. Bacterial lipopolysaccharide (LPS)-induced cytokine storm-AKI also upregulated kidney RUNX1. Increased tubular and interstitial RUNX1 expression were also observed in human AKI. In cultured murine tubular cells, the proinflammatory cytokine TWEAK and LPS increased RUNX1 and IL-6 expression. Mechanistically, RUNX1 bound to the Il-6 gene promoter while RUNX1 targeting with either the chemical inhibitor Ro5-3335 or a specific small interfering RNA (siRNA) prevented the TWEAK- and LPS-induced upregulation of IL-6 through a RUNX1/NFκB p50 pathway. TWEAK and LPS also induced RUNX1 binding to the promoter of Cdkn1a which encodes the cyclin-dependent kinase inhibitor p21 and increased p21 expression. In vivo, preventive Ro5-3335 improved kidney function and reduced inflammation and p21 expression in both FA-AKI, and in cytokine storm-AKI. However, administration of Ro5-3335 after the insult only improved kidney function in cytokine storm-AKI. Kidney transcriptomics identified inflammatory genes and the transcription factor Yap1 as key targets of Ro5-3335 in cytokine storm-AKI. In conclusion, RUNX1 contributes to AKI by driving the expression of genes involved in inflammation and represents a novel therapeutic target in AKI.

Project description:ETV6-RUNX1 is a first-hit mutation in childhood B cell precursor acute lymphoblastic leukaemia. ETV6-RUNX1 is a fusion protein which inherits the DNA-binding runt domain from RUNX1. Here we performed chromatin precipitation for native RUNX1 and ETV6-RUNX1 using RUNX1 antibodies and specifically for the ETV6-RUNX1 fusion using a V5-tag pull down.

Project description:The goal of this observational study is to compare anesthetic modalities (intravenous propofol anesthesia with sevoflurane gas anesthesia) in patients who underwent colorectal cancer resection surgery regarding the outcome of acute kidney injury.
The main questions it aims to answer are:
* is there a difference in acute kidney injury incidence in the two anesthetic modalities?
* is there a difference in plasma creatinine between the two anesthetic modalities?
* are there any patient characteristics or intraoperative factors that effect the incidence of acute kidney injury in either anesthetic modality?
The study will analyze data from the CAN clinical trial database. (Cancer and Anesthesia: Survival After Radical Surgery - a Comparison Between Propofol or Sevoflurane Anesthesia, NCT01975064)

Project description:ETV6-RUNX1 is a fusion protein bringing together almost the entire coding sequence of RUNX1, including the DNA binding runt domain, and the N-terminus of ETV6 which is known to include transcriptional repressors including histone deacetylation 3 (HDAC3). Here we perform ChIP-seq for the active chromatin mark H3K27ac in the NALM6 B-cell acute lymphoblastic leukaemia cell line expressing ETV6-RUNX1 or mutant derivatives of ETV6-RUNX1: Delta helix-loop-helix (dHLH) is a deletion of the pointed domain; R139G is a point mutation in the runt DNA-binding domain.

Project description:Cellular binary fate decisions require the progeny to silence genes associated with the alternative fate. The major subsets of alpha:beta T cells have been extensively studied as a model system for fate decisions. While the transcription factor RUNX3 is required for the initiation of Cd4 silencing in CD8 T cell progenitors, it is not required to maintain the silencing of Cd4 and other helper T lineage genes. The other runt domain containing protein, RUNX1, silences Cd4 in an earlier T cell progenitor, but this silencing is reversed whereas the gene silencing after RUNX3 expression is not reverse. Therefore, we hypothesized that RUNX3 and not RUNX1 recruits other factors that maintains the silencing of helper T lineage genes in CD8 T cells. To this end, we performed a proteomics screen of RUNX1 and RUNX3 to determine candidate silencing factors.

Project description:RUNX1 and ETV6-RUNX1 possess the same DNA-binding runt domain and are therefore expected to bind to canonical RUNX motifs. As the ETV6-RUNX1 fusion arises in the context of native RUNX1 expression, and since RUNX1 is retained or amplified in B-ALL, the two proteins are likely to compete for the same target sites. To assess this, we performed RUNX1 ChIP-seq in the presence of exogenous ETV6-RUNX1 (or non DNA binding ETV6-RUNX1-R139G) and the reciprocal experiment: ETV6-RUNX1 ChIP (using a V5 tag) in the presence of exogenous RUNX1 or vector control.

Project description:Runt-related transcription factor 1 (RUNX1) plays critical roles in hematopoiesis including myeloid development. Runx1 binds Runt consensus motifs at promoters and regulatory elements of its target genes. Interestingly, several Runx1-binding RNA aptamers have been successfully developed. Additionally, mounting evidences suggest that transcription factors are capable of binding to RNAs. In this study, we performed a transcriptome-wide screen for Runx1-interacting RNAs in living cells using fRIP-Seq. Anti-Runx1 antibody was used to capture Runx1 in the monocytic cell line THP-1. RNAs co-immunoprecipitated with Runx1 were sequenced by paired-end massively parallel sequencing and analyzed by HOMER peak calling and annotation algorithms. By doing so, we identified a repertoire of RNAs interacting with Runx1. We further investigate functional role of these interactions in Runx1-mediated transcription regulation.

Project description:Despite absent expression in normal hematopoiesis, the Forkhead factor FOXC1, a critical mesenchymal differentiation regulator, is highly expressed in ~30% of HOXAhigh AML to confer blocked monocyte/macrophage differentiation. Through integrated proteomics and bioinformatics, we discovered that FOXC1 and RUNX1 interact through Forkhead and Runt domains respectively and cooccupy primed and active enhancers distributed close to differentiation genes. FOXC1 stabilises association of RUNX1, HDAC1 and Groucho repressor TLE3 to limit enhancer activity: FOXC1 knockdown induced loss of repressor proteins, gain of CEBPA binding, enhancer acetylation and upregulation of nearby genes, including KLF2. Furthermore, it triggered genome-wide redistribution of RUNX1, TLE3 and HDAC1 from enhancers to promoters leading to repression of self-renewal genes including MYC and MYB. Our studies highlight RUNX1 and CEBPA transcription factor swapping as a feature of leukemia cell differentiation, and reveal that FOXC1 prevents this by stabilising enhancer binding of a RUNX1/HDAC1/TLE3 transcription repressor complex, to oncogenic effect.

Project description:Gene expression profiling of kidneys from the murine model of HIV-associated nephropathy (HIVAN) identified an association between the expression of an endoplasmic reticulum (ER)-associated protein reticulon-1, RTN1, and the severity of kidney disease. Of the three known RTN1 isoforms, only RTN1A protein expression was increased in kidneys of murine models of HIVAN, diabetic nephropathy (DN), and renal fibrosis and humans with HIVAN and DN. Both mRNA and protein expression of RTN1-A in the kidneys correlated inversely with estimated glomerular filtration rate (eGFR) in patients with DN. In kidney cells, RTN1 overexpression induced ER stress/apoptosis, whereas RTN1 knockdown attenuated tunicamycin-, and hyperglycemia-induced ER stress/apoptosis. Incubation of kidney cells with high glucose media induced RTN1A expression likely through oxidative pathway, while knockdown of RTN1A inhibited high glucose-induced apoptosis. RTN1A interacts with PERK and mutation of its N- or C-terminal domain abolished its effects on ER stress/apoptosis. In vivo, knockdown of Rtn1a expression either before or after kidney injury attenuated renal fibrosis in mice with unilateral ureteral obstruction (UUO) and tubular epithelial cell-specific knockdown of Rtn1a also ameliorated ER stress and renal fibrosis in the UUO mice. Finally, knockdown of Rtn1a also attenuated proteinuria, glomerular hypertrophy, and mesangial expansion in STZ-induced diabetic mice, which were associated with suppression of ER stress markers. Taken together, these data suggest that RTN1 is a mediator of kidney disease progression that exacerbates kidney injury through ER stress and apoptosis. Animal studies: All animal studies were approved by the IACUC committee of Mount Sinai School of Medicine. HIV-1 transgenic mice, Tg26, and their littermates were generated and genotyped as described. Only male heterozygous Tg26 in the FVB/N background were used in the study, because homozygous HIV-transgenic mice are not viable for more than few weeks postnatally. UUO and folic acid-induced nephropathy models were created as described . Mice were grouped as wild type, Tg26 with mild kidney injury, Tg26, with serious kidney injury. The kidneys were collected from these mice for histology, western blot, real-time PCR analysis, and microarray studies. Kidney disease was confirmed by measurement of proteinuria, renal function, and histologic analysis. Microarray studies: Affymetrix gene expression microarrays were performed at the Mount Sinai Institution Microarray Core Facility. The Affymetrix GeneChip® Mouse Genome 430 2.0 Array was used to profile gene expression in the kidney cortex of Tg26 and WT mice 37. One-way analysis of variance test (ANOVA) was applied to the dataset to identify the genes that were differentially expressed between the two groups. P-values were corrected using Benjamini–Hochberg false discovery rate (FDR) with a threshold of 0.05.
