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.

Identifying dormant cells in colorectal cancer spheroids

Project description:Cellular dormancy and heterogeneous cell cycle lengths provide important explanations for treatment failure following adjuvant therapy with S-phase cytotoxics in colorectal cancer (CRC) yet the molecular control of the dormant versus cycling state remains unknown. In CRCs dormant cells are found to be highly clonogenic and resistant to chemotherapies. We sought to understand the molecular features of dormant CRC cells to facilitate rationale identification of compounds to target both dormant and cycling tumour cells.

Transcriptional Regulation by NFATc1 during murine thymocyte development [ChIP-seq]

Project description:In thymus hematopoietic precursor cells differentiate into αβ T cells, γδ T cells, mucosa-associated invariant T cells (MAIT), and natural killer T (NKT) cells. We show that both ablation of NFATc1 or its induction during the DN stages of thymocyte development leads to an almost normal thymocyte development but a marked increase in γδ T cells. The γδ cells deficient for NFATc1 acquire an NKT γδ cell phenotype that exhibits the expression of CD4 co-receptor, the NK1.1 marker, the augmented usage of the Vγ1.1 and Vδ6.3 segments, and an increased in IL4 and IFN-γ production.

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.

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).

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.
