(Submitter supplied) Though expression of the homeobox transcription factor Nanog is generally restricted to pluripotent cells and early germ cells, recent reports have found that Nanog is re-expressed in somatic and germ cell tumors associated with poor differentiation and aggressive disease progression. To elucidate its oncogenic properties, a modified Tet-On system was utilised to generate Nanog-inducible mice. By dexamethasone and doxycycline injection, similar Nanog expression levels as in wild-type embryonic stem cells were obtained in all major organs except for brain. more...

(Submitter supplied) Aberrant expression of the homeodomain transcription factor CDX2 occurs in most cases of acute myeloid leukemia (AML) and promotes leukemogenesis, making CDX2, in principle, an attractive therapeutic target. Conversely, CDX2 acts as a tumor suppressor in colonic epithelium. The effectors mediating the leukemogenic activity of CDX2 and the mechanism underlying its context-dependent properties are poorly characterized, and strategies for interfering with CDX2 function in AML remain elusive. more...

(Submitter supplied) Atoh1 is the master transcription factor of intestinal secretory cells. Lineage-tracing model of Atoh1+ve cells showed that the progeny of Atoh1+ve cells can develop into either LGR5+ve or LGR5-ve cells. Present analysis compared the gene expression profile of Atoh1+ve cell-derived LGR5+ve cells and LGR5-ve cells, compared to the resident LGR5+ve cell population of the mouse small intestine.

(Submitter supplied) Atoh1 is the master transcription factor of secretory-type intestinal epithelial cells. By using a lineage-tracing model of Atoh1+ve cells, those Atoh1+ve epithelial cells and their descendants were collected from the colon of DSS-colitis mice or from the control mice, and subjected to global gene expression analysis.

(Submitter supplied) Somatic DNA alteration underlies tumor development and progression, and gives rise to tumors with diverse genetic contexts. Here, we identify in a collection of 29 colorectal cancer cell lines and 226 primary colorectal tumors recurrent amplification of chromosome 13, an alteration highly restricted to colorectal-derived cancers. A minimal region of amplification on 13q12.2 pinpoints caudal type homeobox transcription factor CDX2, a master regulator of anterior-posterior patterning, midgut development, and intestinal epithelial cell differentiation and maintenance. more...

(Submitter supplied) NANOG is a key transcription factor for pluripotency in embryonic stem cells. However, its role in adult tissues remains largely unexplored. Here, we show that mouse NANOG is expressed in the progenitor layer of stratified epithelia, including esophagus, forestomach and skin. Accordingly, the Nanog promoter is hypomethylated in the epithelial layers of the esophagus and forestomach. Interestingly, ubiquitous transgenic overexpression of NANOG in mice induces hyperplasia in stratified epithelia, but not in other tissues. more...

(Submitter supplied) NANOG is a key pluripotency factor in embryonic stem cells that is frequently expressed in squamous cell carcinomas (SCCs). However, a direct link between NANOG and SCCs remains to be established. Here, we show that inducible overexpression of NANOG in mouse skin epithelia dramatically promotes the formation of carcinomas upon chemical carcinogenesis. Gene expression analyses in pre-malignant skin indicate that NANOG induces a large set of genes associated to stemness and to epithelial-mesenchymal transition (EMT).

(Submitter supplied) Stomach and intestinal adult epithelia harbor stem cells that are responsible for their continuous regeneration. Stomach and intestinal stem cells differ in their differentiation program and in the gene repertoire that they express. We show that single adult Lgr5-positive stem cells, isolated from 3D cultured small intestinal organoids, require Cdx2 to maintain their intestinal identity and are converted cell-autonomously into stomach-pyloric stem cells in the absence of this transcription factor.

(Submitter supplied) Organoids are a valuable 3D model to study the differentiated functions of the human intestinal epithelium. They are a particularly powerful tool to measure epithelial transport processs in health and disease. Though biological assays such as organoid swelling and intraluminal pH measurements are well established, their underlying functional genomics are not well characterized. Here we combine genome-wide analysis of open chromatin by ATAC-seq with transcriptome mapping by RNA-seq to define the genomic signature of human intestinal organoids (HIOs). more...

(Submitter supplied) It is not known why cancers arising in anatomically distinct locations but within the same tissue type can exhibit stark differences in molecular, pathological and clinical features. Cancers arising in proximal and distal sites of the colon are emblematic of these above differences as the proximal and distal colon cancers harbor differences in key molecular features, with BRAFV600E oncogene predominantly occurring in proximal colon cancers in the context of the increased promoter DNA methylation phenotype (CIMP-high), while distal colon cancers lack these molecular features. more...
