Affymetrix Mouse Gene 2.0 ST Array (mogene20st)
Description
Recognition and removal of apoptotic cells by professional phagocytes, including dendritic cells and macrophages, preserve self-tolerance and prevent chronic inflammation and autoimmune pathologies. However the diverse array of phagocytes residing within different tissues combined with the necessarily prompt nature of apoptotic cell clearance has made it difficult to study this process in situ. Thus, the full spectrum of functions executed by tissue resident phagocytes in response to homeostatic apoptosis remains unclear.
Publication Title
Different tissue phagocytes sample apoptotic cells to direct distinct homeostasis programs.

Description
The preferential localization of some neoplasms, such as serrated polyps, in specific areas of the intestine suggests that non-genetic factors may be important for their development. To test this hypothesis, we took advantage of transgenic mice that expressed HB-EGF throughout the intestine, but develop serrated polyps only in the cecum.

Description
APCmin/+ mice develop spontaneous gastrointestinal polyposis due to a dominantly inhereited germline loss-of-function mutation in the tumor suppressor adenomatous polyposis coli (APC). Changes in intestinal immune activity have been documented to occur prior to the development of fulminate polyposis. Such changes are thought to contribute to disease development.

Description
Inflammatory response has been identified as a molecular signature of high-risk Group A ependymoma (EPN). To better understand the biology of this phenotype and aid therapeutic development, transcriptomic data from Group A and B EPN patient tumor samples, and additional malignant and normal brain data, were analyzed to identify the mechanism underlying EPN group A inflammation.

Description
This serie was performed on liver progenitor isolated based on their expression of the Sca1 surface marker. It contains two independent samples from Rb family deficient liver and three independent samples from control liver, all isolated 2 weeks after Tamoxifen-induced Rb family ablation. Hematopoietic (CD45, Ter119) and endothelial (CD31) markers were used as negative selection markers to exclude blood or endothelial cells from the isolated fraction.

Description
p53 is a pivotal tumor suppressor and a major barrier against cancer. We now report that silencing of the Hippo pathway tumor suppressors LATS1 and LATS2 in non-transformed mammary epithelial cells reduces p53 phosphorylation and increases its association with the p52 NF-?B subunit. Moreover, it partly shifts p53’s conformation and transcriptional output towards a state resembling cancer-associated p53 mutants, and endow p53 with the ability to promote cell migration. Notably, LATS1 and LATS2 are frequently downregulated in breast cancer; we propose that such downregulation might benefit cancer by converting p53 from a tumor suppressor into a tumor facilitator. Overall design: MCF10A cells transfected with siRNA against LATS1/2 alone, p53 alone or LATS1/2 and p53 together. Two independent MCF10A batches provided biological replicates
Publication Title
Down-regulation of LATS kinases alters p53 to promote cell migration.

Description
Background & Aims: HNF4 is an important transcriptional regulator of hepatocyte and pancreatic function. Hnf4 deletion is embryonically lethal with severe defects in visceral endoderm formation, liver maturation and colon development. However, the precise role of this transcription factor in maintaining homeostasis of the adult intestine remains unclear. Herein, we aimed to elucidate the adult intestinal functions of Hnf4. Methods: A conditional intestinal epithelial Hnf4 knockout mouse was generated. Histological abnormality of the colonic mucosa was assessed by immunodetection and Western. Changes in global gene expression and biological network were analyzed. Results: Hnf4 intestine null mice developed normally until reaching young adulthood. Crypt distortion became apparent in the Hnf4 null colon at 3 months of age followed by focal areas of crypt dropout, increased immune cell infiltrates, crypt hyperplasia and early signs of polyposis later in life. A gene profiling analysis identified cell death and cell cycle related to cancer as the most significant sets of genes altered in the Hnf4 colon null mice. Expression levels of the tight junction proteins claudin 4, 8 and 15 were altered early in the colon epithelium of Hnf4 mutants and correlated with increased barrier permeability to a molecular tracer that does not normally penetrate normal mucosa. Conclusion: These observations support a functional role for Hnf4 in protecting the colonic mucosa against the initiation of the changes resembling inflammatory bowel diseases and polyp formation.
