Global analysis of NFATc1 binding and histone marks in VEGF-activated endothelial cells

ABSTRACT: We performed the newly mapping of genome-wide NFATc1 binding events in VEGF-stimulated primary cultured endothelial cells, by chromatin immunoprecipitation followed by high-throughput sequencing (ChIP-seq). Combined NFATc1 ChIP-seq profile and the epigenetic histone marks revealed that predominant NFATc1-occupied peaks were overlapped with promoter marking but not silencer marking. DNA microarrays with NFATc1 expression or knockdown indicated the predominant NFATc1 binding targets were correlated with induced patterns. Examination of NFATc1 and two different histone marks in HUVEC in the presence/absense of VEGF.

Global analysis of NFATc1 targets in human vascular endothelial cells

Project description:We performed the newly mapping of genome-wide NFATc1 binding events in VEGF-stimulated primary cultured endothelial cells, by chromatin immunoprecipitation followed by high-throughput sequencing (ChIP-seq). Combined NFATc1 ChIP-seq profile and the epigenetic histone marks revealed that predominant NFATc1-occupied peaks were overlapped with promoter marking but not silencer marking. DNA microarrays with NFATc1 expression or knockdown indicated the predominant NFATc1 binding targets were correlated with induced patterns. To determine NFATc1-regulated genes, a total of 5 samples were derived from human umbilical vein endothelial cells (HUVECs) stimulated with or without 50ng/mL VEGF (VEGF 60min and 0min, respectively), pretreated with cyclosporine A (VEGF 60min plus CsA) and infected with adenovirus expressing the control or constitutively active NFATc1 (Ad-control and Ad-NFATc1).

Genome-wide maps of H3K27ac, PPARβ/δ and Pol II localization in HUVECs

Project description:H3K27Ac is one of the expressed enhancer markers, PPARβ/δ is a transcription factor and Pol II (RNA polymerase II) is an enzyme which catalyzes the transcription of DNA to synthesize precursors of mRNA and most snRNA and microRNA. These genomic localization in endothelial cells is unknown in endothelial cells. This time, we established a new antibody for H3K27ac, PPARβ/δ and Pol II and performed ChIP-seq to identify H3K27ac, PPARβ/δ and Pol II binding site in whole genome manner under PPARβ/δ agonist and/or hypoxia. We used chromatin immunoprecipitation with deep sequencing (ChIP-seq) of HUVECs treated with PPARβ/δ agonist (GW501516 100nM) and/or hypoxia (1%O2) for 24hours, then H3K27ac, PPARβ/δ and Pol II binding regions were identified. Normoxia and DMSO was used as a control condition. HUVECs were used within the first 6 passages.

Identifying dormant Nfatc1-marked stem/progenitor cells as an important contributor for mammary lobuloalveoli formation

Project description:The Mammary gland undergoes complicated epithelial remodeling to form lobuloalveoli during pregnancy, in which basal epithelial cells remarkably increase to form a basket-like architecture. However, it remains largely unknown how dormant mammary basal stem/progenitor cells involve in lobuloalveolar development. Here, we show that Nfatc1 expression marks a rare population of mammary epithelial cells with the majority being basal epithelial cells. Nfatc1 reporter-marked basal epithelial cells are relatively dormant mammary stem/progenitor cells. Although Nfatc1 reporter-marked basal epithelial cells show limited contribution to the homeostasis of mammary epithelium, they divide rapidly during pregnancy and contribute to lobuloalveolar development. Furthermore, Nfatc1 reporter-marked basal epithelial cells are preferentially used for multiple pregnancies. Using single-cell RNA-seq analysis, we identify multiple functionally distinct clusters within the Nfatc1 reporter-marked cell-derived progeny cells during pregnancy. Taken together, our findings underscore Nfatc1 reporter-marked basal cells as dormant stem/progenitor cells that contribute to mammary lobuloalveolar development during pregnancy.

Transcriptome analysis of WEHI B lymphoma cells overexpressing individual NFATc1 proteins

Project description:In lymphocytes, NFATc1 is the most prominent NFAT transcription factor which play a crucial role in the fate and activity of peripheral T and B cells. NFATc1 is synthesized in two prominent isoforms, the inducible short isoform NFATc1/aA and the constitutively expressed long isoform NFATc1/C. Several lines of evidence suggested that both isoforms differ markedly in their function. It was speculated that NFATc1/aA supports the proliferation and survival of lymphocytes, whereas NFATc1/C should support apoptosis and anergy induction. To proof this hypothesis we established WEHI 231 B lymphoma cells that stably (over-) express either NFATc1/aA or NFATc1/C. In preliminary experiments we could should that WEHI cells overexpressing NFATc1/aA were protected against apoptosis induction, while cells overexpressing NFATc1/C should a higher apoptosis rate. Transcriptom analysis of WEHI-231 cells overexpressing either NFATc1/aA or NFATc1/C were performed, along with a control group of WEHI-231 cells overexpressing the E.coli enzyme BirA Ligase (which is also present in all target cell lines since for further molecular assays the NFATc1 proteins were expressed as chimeric protein containing C-terminal bio-tags. The experimental results obtained indicate that the both NFATc1 proteins, NFATc1/aA and NFATc1/C, differ tremendously in their transcriptional properties.

Nfatc1 promotes stem cell contribution to squamous skin tumors

Project description:We find that epithelial-specific deletion of Nfatc1 decreases skin tumor susceptibility in mice subjected to DMBA/TPA carcinogenesis. To probe the molecular mechanisms by which Nfatc1 may regulate tumorigenesis, we identify gene expression changes associated with constitutive NFATc1 activation in primary mouse keratinocytes. Constitutively active NFATc1 activity in primary mouse keratinocytes to investigate how Nfatc1 regulates tumor initiation in the skin. Primary mouse keratinocytes were infected with retroviruses encoding a recombinant human NFATc1 containing mutations in the autoinhibitory domain that render it constitutively active (CAC1). Keratinocytes infected with retroviruses generated from an empty MSCV reotroviral vector were used as a control. Three biological replicates were performed.

Comparison expression data from wild-type and NFATc1-deficient osteoclasts

Project description:Genetic deletion of Nfatc1 in mice results in profound osteoclast-poor osteopetrosis, a high bone mass state caused by a lack of osteoclast activity. We hypothesized that the family of NFATc1 regulated transcripts in the osteoclast would be enriched for genes associated with osteoclast function. We used microarrays profile gene expression in wild-type and NFATc1-deficient osteoclasts generated in vitro to identify NFATc1-dependent transcripts in osteoclasts. Bone marrow macrophages from wild-type and mice with an induced deficiency of NFATc1 (NFATc1 fl/fl MxCre+ mice where NFATc1 excision was induced by polyIC treatment) were cultured ex vivo in MCSF and RANKL for 3 days. 2 biological replicates were assayed for each genotype.

NFATc1 cooperates with KrasG12D to promote pancreatic carcinogenesis.

Project description:Primary murine pancreatic cancer cells (referred to as NKC cells) derived from transgenic mice with pancreas-specific constitutive activation of NFATc1 and KrasG12D mutation in the presence or absence of NFATc1 expression were analyzed for target gene signatures.
