Project description:The Forkhead family of transcription factors comprises numerous members and is implicated in various cellular functions, including cell growth, apoptosis, migration and differentiation.In this study we identified the Forkhead factor FoxQ1 as increased in expression during TGF-beta1 induced changes in epithelial differentiation, suggesting functional roles of FoxQ1 for epithelial plasticity.The repression of FoxQ1 in mammary epithelial cells led to a change in cell morphology characterized by an increase in cell size, pronounced cell-cell contacts and an increased expression of several junction proteins (e.g. E-cadherin). In addition, FoxQ1 knock-down cells revealed rearrangements in the actin-cytoskeleton and slowed down cell cycle G1-phase progression.Furthermore, repression of FoxQ1 enhanced the migratory capacity of coherent mammary epithelial cells.Gene expression profiling of NM18 cells indicated that FoxQ1 is a relevant downstream mediator of TGF-beta1 induced gene expression changes. This included the differential expression of transcription factors involved in epithelial plasticity, e.g. Ets-1, Zeb1 and Zeb2.In summary, this study has elucidated the functional impact of FoxQ1 on epithelial differentiation

Project description:FOXQ1 is a putative oncogene in several types of carcinomas and, in colorectal cancers, is one of the most highly upregulated genes. FOXQ1 has been previously identified as a candidate Wnt pathway activator in CRC cells. However, it is still unclear how the crosstalk between FOXQ1 and Wnt signalling influence the global behaviour of colorectal cancer cells. Here, we performed bulk RNA sequencing of FOXQ1 or vector transfected HCT116 cells with or without Wnt3a treatment. Each condition was performed in biological triplicates.

Project description:We report the genome wide RNA sequencing for high-throughput profiling of FOXQ1 target genes in melanoma and carcinoma cells. We generated melanoma (SK-Mel-147) and ovarian carcinoma cells (SCOV3) ectopically expressing FOXQ1. We find that FOXQ1 differentially regulates the expression of several genes in melanoma cells as compared to carcinoma cells. Specifically, FOXQ1 induces the expression of several genes in ovarian carcinoma cells SCOV3 and suppresses the expression of the same genes in melanom cells. We show that this differentialy regulation of the same target gene depends upon the nuclear levels of beta-catenin. High levels of active nuclear beta-catenin promote FOXQ1 mediated transcriptional activation of genes whereas low levels contribute to TLE/Groucho- mediated repression. This study provides a framework for understanding the lineage specific pattern of transcriptional regulation by FOXQ1 and its contextual determinants.

Project description:Transcription factor Foxq1 controls mucin gene expression and granule content in mouse stomach surface mucous cells ; Background and Aims: The gastric mucosa provides a stringent epithelial barrier and produces acid and enzymes that initiate digestion. In this regenerating tissue, progenitors differentiate continually into 4 principal specialized cell types, yet underlying mechanisms of differentiation are poorly understood. We identified stomach-restricted expression of the forkhead transcription factor FOXQ1. Methods: We used a combination of genetic, histochemical, ultrastructural and molecular analysis to study gastric cell lineages with respect to FOXQ1. Results: Within the developing and adult gastrointestinal tract, Foxq1 mRNA is restricted to the stomach, expressed prominently in foveolar (pit) cells, the abundant mucin-producing cells that line the mucosal surface, and required for their complete differentiation. Mice carrying Foxq1 coding mutations show virtual absence of mRNA and protein for the backbone of the predominant stomach mucin, MUC5AC. These observations correspond to a paucity of foveolar-cell secretory vesicles and notable loss of stomach but not intestinal mucus. Transcriptional profiling identified a surprisingly restricted set of genes with altered expression in Foxq1 mutant stomachs. MUC5AC is a highly tissue-restricted product that similarly depends on FOXQ1 in its other major site of expression, conjunctival goblet cells. Conclusions: Taken together, these observations imply that promotion of gastric MUC5AC synthesis is a primary, cell-autonomous function of FOXQ1. This study is the first to implicate a transcription factor in terminal differentiation of foveolar cells and begins to define the requirements to assemble highly specialized organelles and cells in the gastric mucosa. DOI: 10.1053/j.gastro.2008.04.019 Experiment Overall Design: RNA from stomach antrum from 2 of each Satin, Beige, and BL6 mice were compared using microarray analysis.

Project description:FOXQ1 transcription factors is highly induced in several types of carcinomas where it promotes tumour growth and metastasis, however, the molecular mechanisms leading to FOXQ1 deregulation in cancer are incompletely understood. Here, we used a CRISPR/Cas9-based genomic locus proteomics (GLoPro) to discover transcriptional regulators of FOXQ1 and identified the tumour suppressor p53 as a transcriptional repressor of FOXQ1 expression. ChIP-qPCR as well as complementary gain and loss-of-function assays in model cell lines indicated that p53 has multiple binding sites close to the transcription start site of the FOXQ1 promoter, and that it suppresses FOXQ1 expression in various cell types. Consistently, pharmacological activation of p53 using nutlin-3 or doxorubicin reduced FOXQ1 mRNA and protein levels in colorectal cancer cell lines harboring wild type p53. In conclusion, these results suggest that mutational loss-of-function of p53, a hallmark feature of many types of cancer, de-represses FOXQ1, which accelerates tumour progression.

Project description:Immunoresponsive gene 1 (IRG1) is one of the highest induced genes in macrophages under pro-inflammatory conditions and its function has been recently described: it codes for immune-responsive gene 1 protein/cis-aconitic acid decarboxylase (IRG1/CAD), an enzyme catalyzing the production of itaconic acid from cis-aconitic acid, a tricarboxylic acid (TCA) cycle intermediate. Itaconic acid possesses specific antimicrobial properties inhibiting isocitrate lyase, the first enzyme of the glyoxylate shunt, an anaplerotic pathway that bypasses the TCA cycle and enables bacteria to survive on limited carbon conditions. To elucidate the mechanisms underlying itaconic acid production through IRG1 induction in macrophages, we examined the transcriptional regulation of IRG1. Using a combination of literature information, transcription factor prediction models and genome-wide expression arrays, we inferred the regulatory network of IRG1 in mouse and human macrophages. 3 unstimulated (Control) and 3 LPS-stimulated RAW 264.7 macrophages

Project description:The forkhead box transcription factor FOXQ1 is aberrantly induced in various cancers, and contributes to tumour growth and metastasis. It has been suggested that the oncogenic potential of FOXQ1 may be explained by its activation of the Wnt/β-catenin signalling pathway.However, the mode of action of FOXQ1 in the Wnt pathway remains to be resolved. Here we report that FOXQ1 is bimodal transcriptional activator of Wnt target gene expression in normal and cancer cells. Using co-immunoprecipitation, proximity proteomics, and reporter assays, we show that FOXQ1 engages the Wnt transcriptional complex to promote gene expressionvia TCF/LEF transcription factors.
