(Submitter supplied) Amoung their pleiotropic functions, a role was recently assigned for b-arrestin scaffold proteins in tumor growth, angiogenesis and invasion. In order to elucidate the roles of b-arrestins in tumour developement in intestinal epithelium initiated by Apc mutation, we determined the effects of b-arrestin gene deletion on intestinal polypolis using ApcD14/+ mice, a relevant mouse model of human intestinal tumorigenesis.Here we show that unlike b-arrestin1, absence of b-arrestin2 dramatically decreased the number of spontaneously developping intestinal tumors in ApcD14/+ mice.The size of residual tumors was similarto that of controls, suggesting that their growth is b-arrestin2-independent. more...

(Submitter supplied) The role of ribosome biogenesis in erythroid development is supported by the recognition of erythroid defects in ribosomopathies in both Diamond-Blackfan anemia and 5q- syndrome. Whether ribosome biogenesis exerts a regulatory function on normal erythroid development is still unknown. In the present study, a detailed characterization of ribosome biogenesis dynamics during human and murine erythropoiesis shows that ribosome biogenesis is abruptly interrupted by the drop of rDNA transcription and the collapse of ribosomal protein neo-synthesis. more...

(Submitter supplied) Wnt signaling plays a pivotal role in colorectal cancer. Intrinsic activation of Wnt by mutational events, such as mutations in the tumor suppressor gene APC, represents the most frequent initiating event in this disease background. Long truncated versions of APC retain partial functionality, which leads to a sub-maximal, “just right” activation state of Wnt signaling supposed to be beneficial for disease initiation. more...

(Submitter supplied) To analyse roles of HAI-1/Spint1 in intestinal tumorigenesis, we examined the effect of intestine-specific deletion of Spint1 gene on Apc(Min/+) mice. The loss of Hai-1/Spint1 significantly accelerated tumor formation in ApcMin/+ mice and shortened their survival periods. Mouse small intestine tumor tissue or background mucosa lacking macroscopically visible tumors were proceeded to RNA extraction and hybridization on microarrays (Affymetrix Mouse Genome 430 2.0 Array).

(Submitter supplied) To assess cellular changes upon abrogation of the WNT-signaling pathway, we induced expression of a dominant-negative T-cell factor 4 (TCF4). This showed a remarkable overlap with activation of the unfolded protein response (UTR) in the same colon cancer cell line.

(Submitter supplied) To assess the effect of activation of the unfolded protein response (UPR) in colon cancer cell lines, we treated cells with the AB5 subtilase cytotoxin (SubAB). This proteolytically cleaves the 78-kDa glucose-regulated protein (GRP78; also known as HSPA5 or BiP) inside the endoplasmic reticulum. We find that the WNT signaling pathway is highly affected upon treatment with SubAB.

(Submitter supplied) Expression profiling is a well established tool for the genome-wide analysis of the transcriptional activity of human neoplasia. However, the high sensitivity of this approach combined with the well-known cellular and molecular heterogeneity of cancer often result in extremely complex and extended expression signatures of difficult functional interpretation. The majority of sporadic colorectal cancer cases are triggered by mutations in the APC tumor suppressor gene leading to constitutive activation of the Wnt/b-catenin signaling pathway and adenoma formation. more...

(Submitter supplied) The majority of sporadic colorectal cancer cases are initiated by mutations in the APC tumor suppressor gene leading to constitutive activation of the Wnt/b-catenin signaling pathway and adenoma formation. Several pre-clinical models carrying germline mutations in the endogenous mouse Apc tumor supressor gene have been generated and their phenotype characterized. The predisposition of these mouse models to multiple intestinal adenomas closely resembles the FAP phenotype at the molecular, cellular and phenotypic level and may prove valuable to elucidate the molecular and cellular mechanisms underlying colorectal tumorigenesis. more...

(Submitter supplied) Relatively little is known about how the identity of early neuronal stem cells changes before and after neural tube closure (neurulation). We performed RNA sequencing on microdissected forebrain precursors and revealed sharp reductions in expresion of protein biosynthetic machinery after neurulation. These reductions were paralleled by down-regulation of Myc, which regulated forebrain precursor ribosome ribosome biogenesis. more...

(Submitter supplied) APC is a key regulator of canonical Wnt signalling since it participates to beta-catenin targeting to proteasomal degradation when the pathway is inactive. Moreover, independently of Wnt signaling, APC regulates several cellular functions such as mycrotubule dynamics, chromosome segregation, cell adhesion. Although APC has been widely studied for its implication in initation and progression of several cancers, its role in satellite cells (skeletal muscle stem cells) has never been investigated. more...

(Submitter supplied) APC mutant mice develop polys in the intestine, but not carcinoma. We found that additional deletion of Olfm4 gene induced carcinoma formation in the distal colon. To explore the molecular mechanism, we performed cDNA microarray to understand the gene expression files in the tumor tissues compared with WT, APC mutant and Olfm4 mutant mice.

(Submitter supplied) Dyskeratosis congenita is a bone marrow failure syndrome characterized by the presence of short telomeres at presentation. The X-linked form is caused by mutations in the gene DKC1, encoding the protein dyskerin. Dyskerin is required for in the assembly and stability of telomerase and is also involved in ribosomal RNA (rRNA) processing where it converts specific uridines to pseudouridine. DC is thought to result from failure to maintain tissues, like blood, that are renewed by stem cell activity, suggesting induced pluripotent stem (iPS) cells from X-linked DC patients may provide information about the mechanisms involved. more...
