Foxa1 and Foxa2 are essential for gender dimorphism in liver cancer

Project description:Foxa1loxP/loxP;Foxa2loxP/loxP and Foxa1loxP/loxP;Foxa2loxP/loxP;AfpCre mice of both genders were treated with or without carcinogen to induce liver cancer. ChIP-Seq was performed in the liver samples after cross-linking. ChIP-DNA was sequenced with the Illumina GAII sequencer. The AfpCre when present knocks out the Foxa1 and Foxa2 genes, so removing the corresponding proteins.

Foxa1 and Foxa2 are essential for sexual dimorphism in liver cancer.

Project description:Hepatocellular carcinoma (HCC) is sexually dimorphic in both rodents and humans, with significantly higher incidence in males, an effect that is dependent on sex hormones. The molecular mechanisms by which estrogens prevent and androgens promote liver cancer remain unclear. Here, we discover that sexually dimorphic HCC is completely reversed in Foxa1- and Foxa2-deficient mice after diethylnitrosamine-induced hepatocarcinogenesis. Coregulation of target genes by Foxa1/a2 and either the estrogen receptor (ERα) or the androgen receptor (AR) was increased during hepatocarcinogenesis in normal female or male mice, respectively, but was lost in Foxa1/2-deficient mice. Thus, both estrogen-dependent resistance to and androgen-mediated facilitation of HCC depend on Foxa1/2. Strikingly, single nucleotide polymorphisms at FOXA2 binding sites reduce binding of both FOXA2 and ERα to their targets in human liver and correlate with HCC development in women. Thus, Foxa factors and their targets are central for the sexual dimorphism of HCC.

Transcriptome of Foxa1/Foxa2-deficient colon [RNA]

Project description:FOXA1 and FOXA2 are essentail transcription factors for proper gut development. In adults, they have a role in the differentiation of intestinal secretory cell lineages and were also reporeted to directly activate Muc2 transcription. Here we show that deletion of Foxa1 and Foxa2 in mouse intestinal epithelium leads to a downregulation of glycosylation genes in the colon and to a massive change of the colonic surface glycans. In turn, the microbiome composition shifts dramatically and spontaneous inflammatory bowel disease ensued. We conclude that vertebrates shape a favorable microbiome by establishing a glycocalyx to nurture specific bacterial taxa through control of the epithelial glycosylation program by the FoxA transcription factors.

Regulatory cistrome landscape of Foxa1 and Foxa2 during prostate cancer progression [ChIP-seq]

Project description:To characterize the genome-wide regulatory cistrome of Foxa1 and Foxa2, we performed both Foxa1 and Foxa2 chromatin immunoprecipitation followed by sequencing (ChIP-seq) on freshly dissociated prostate tumor cells at the early stage (2 weeks post tamoxifen administration) and the late stage (6 months post tamoxifen administration) of NEPC progression, respectively.

FOXA1 and FOXA2 binding profile in mouse colon [ChIP]

Project description:FOXA1 and FOXA2 are essentail transcription factors for proper gut development. In adults, they play a role in the differentiation of intestinal secretory cells and were also reporeted to directly activate Muc2 transcription. Here we show that FOXA1 and FOXA2 bind near goblet cell genes, and are specifically enriched near glycosylation genes. Deletion of these transcription factors in mouse intestine leads to a downregulation of glycosylation genes in the colon and to a massive change of the colonic surface glycans. I turn, the microbiome composition shifts dramatically and spontaneous inflammatory bowel disease ensued. We conclude that vertebrates shape a favorable microbiome by establishing a glycocalyx to nurture specific bacterial taxa through control of the epithelial glycosylation program by the FoxA transcription factors.

The pioneer transcription factors Foxa1 and Foxa2 regulate alternative RNA splicing during positive selection in the thymus

Project description:Here we show that the pioneer transcription factors Foxa1 and Foxa2 are required to regulate RNA splicing during positive selection at the transition from CD4+CD8+ double positive (DP) to single positive (SP thymocyte). Conditional deletion of both Foxa1 and Foxa2 from DP thymocytes led to a partial arrest at the transition from DP to SP, with a reduction in the number of cells undergoing positive selection, and reduced the number and maturation of both CD4SP and CD8SP populations, with a reduction in peripheral naïve CD4+ T-cells. Foxa1 and Foxa2 were required for physiological levels of expression of several genes which encoding splicing factors (Mbnl1, Sf3b1, Hnrnpa1) in cells undergoing positive selection. Within the positively selecting CD69+DP cells, alternative RNA splicing was dysregulated leading to more than 859 significantly differentially expressed exons compared to control, with many genes important for T cell development and for RNA splicing showing differentially used exons.

FoxA1 and FoxA2 are required for gastric differentiation in NKX2-1-negative lung adenocarcinoma [single cell analysis]

Project description:Profound changes in cancer cell identity can alter malignant potential and therapeutic response. Loss of the pulmonary lineage specifier NKX2-1 augments the growth of KRAS-driven lung adenocarcinoma and causes pulmonary to gastric transdifferentiation. Here we show that the transcription factors FoxA1 and FoxA2 are required for initiation of mucinous NKX2-1-negative lung adenocarcinomas in the mouse and for activation of their gastric differentiation program. Foxa1/2 deletion severely impairs tumor initiation and causes a proximal shift in cellular identity, yielding tumors expressing markers of the squamocolumnar junction of the gastrointestinal tract. In contrast, stochastic loss of FoxA1/2 expression in NKX2-1-negative tumors is associated with keratinizing squamous differentiation. Using sequential in vivo recombination, we find that FoxA1/2 loss in established KRAS-driven neoplasia is sufficient for direct induction of keratinizing squamous cell carcinomas in the lung. Thus, NKX2-1, FoxA1 and FoxA2 coordinately regulate the growth and identity of lung adenocarcinoma in a context-specific manner.
