Transcription profiling by array of Apc-deficient proximal colonic epithelium upon Msx1 transcription factor depletion

ABSTRACT: The first step in the development of human colorectal cancer (CRC) is the aberrant hyperactivation of the Wnt signaling pathway, predominantly caused by inactivating mutations in the adenomatous polyposis coli (APC) gene which encodes an essential tumor suppressor. In order to identify genes affected by Apc loss, expression profiling of intestinal epithelium isolated from mice harboring the conditional allele of the gene was performed. The gene encoding transcriptional factor msh homeobox 1 (Msx1) displayed robust upregulation upon Apc inactivation. To characterize the gene signature in colon upon Msx1 depletion, colonic epithelium from mice harboring conditional alleles of Apc and Msx1 was isolated and the gene expression profile was compared with control mice harboring the conditional allele of Apc only.

Transcription profiling by array of Apc-deficient mouse small intestinal epithelium upon Msx1 depletion.

Project description:The first step in the development of human colorectal cancer is the aberrant hyperactivation of the Wnt signaling pathway, predominantly caused by inactivating mutations in the adenomatous polyposis coli (Apc) gene encoding an essential tumor suppressor. The gene encoding transcriptional factor msh homeobox 1 (Msx1) displayed robust upregulation upon Apc inactivation in intestinal epithelium isolated in mice harboring the conditional allele of the Apc gene. To identify the gene signature in the small intestine upon Msx1 depletion, small intestinal epithelium from mice harboring conditional alleles of Apc and Msx1 was isolated and the gene expression profile was compared with control mice harboring the conditional allele of Apc only.

Transcription profiling by array of human colorectal cancer SW620 cells upon MSX1 depletion.

Project description:The first step in the development of human colorectal cancer (CRC) is the aberrant hyperactivation of the Wnt signaling pathway, predominantly caused by inactivating mutations in the adenomatous polyposis coli (APC) gene encoding an essential tumor suppressor. In order to identify genes affected by Apc loss, expression profiling of intestinal epithelium isolated from mice harboring the conditional allele of the gene was performed. The gene encoding transcriptional factor msh homeobox 1 (Msx1) displayed robust upregulation upon Apc inactivation. Subsequently, the expression pattern of human MSX1 was examined in a collection of colonic tumors. The MSX1 mRNA level was increased in all types of human intestinal neoplasia tested. In order to identify genes affected by MSX1 loss, expression profiling of human colorectal cancer cells SW620 upon MSX1 gene depletion was performed.

Transcription profiling by array of effects of TMEM70 downregulation on gene expression in liver of spontaneously hypertensive rats

Project description:TMEM70 (transmembrane protein 70), a 21 kDa protein localized in the inner mitochondrial membrane, facilitates the biogenesis of mammalian F1Fo ATP synthase. Mutations of Tmem70 gene represent most frequent cause of isolated deficiency of human ATP synthase resulting in a severe, often fatal neonatal mitochondrial encephalo-cardiomyopathy. Contrary to humans, targeting of Tmem70 results in embryonic lethality in both mice and rats. In the current study, we tested effects of downregulation of the Tmem70 gene on gene transcription in the SHR (spontaneously hypertensive rat) heterozygotes.We performed gene expression profiling in the liver and found differentially expressed genes involved in innate imunity (RT1-T24-4, RT1-N3, RT1-CE5, Cd36, Marco, Socs3) and regulation of oxidative phosphorylation (Cdk1, Ccna2, Slc25a3).

Expression data from mouse intestinal organoids I

Project description:APC inactivation is the early process in the tumorigenesis of colorectal cancer. We established organoid cultures from intestines of genetically modifeid mice harboring Apcfl/fl and R26CreERT2 allele We used microarrays to determine the alterations in intestinal stem cells in response to APC inactivation. Organoids were treated with 4OHT to induce recombination of APC or left untreated, and collected at 4 or 6 days after treatment. RNA were extracted and hybridization on Affymetrix microarrays.

Gene expression profiling of uterine epithelial cells isolated from Msx1Msx2 floxed and Msx1Msx2 ablated mice on day 4 of pregnancy

Project description:Our preliminary study revealed that the homeobox transcription factors, Msx1 and Msx2, are expressed in the mouse uterus during early pregnancy. Further, conditional deletion of Msx1 and Msx2 in mouse uterus leads to implantation failure due to impaired uterine epithelial receptivity. To identify the downstream targets of Msx1Msx2 in the uterus, we performed gene expression profling of uterine epithelial cells isolated from Msx1Msx2-null mice and the corresponding controls on day4 of pregnancy (the time of implantation). The microarray results revealed elevated expression of mRNAs corresponding to several Wnts in uterine epithelium of Msx1Msx2-ablated mice. We performed conditional ablation of Msx1Msx2 in the mouse uterus using the PRcre mouse model. we isolated uterine epithelial cells from day4 pregnant mice (n=5 for each genotype). Total RNA was purified from these cells to hybridize to high density affymetrix microarrays.

Transcriptome analysis of Brg1 deficient small intestinal epithelium in the context of normal and aberrant Wnt signalling

Project description:Brg1 has been reported to act as a trans-activator for the Wnt pathway by interacting with beta-catenin. Given this interaction and the crucial role Wnt signalling plays in the intestinal homeostasis, we aimed to investigate the effect of Brg1 loss on gene expression in normal and Wnt activated small intestinal epithelium. We used VillinCreERT2 Cre recombinase and loxP targeted allels of Brg1 and Apc to generate 4 cohorts of conditional knock-out mice: Cre-negative controls (n=4), Brg1 deficient (n=4), Apc deficient (n=3) and double Brg1-Apc deficient (n=4). All mice were induced by 4x80mg/kg daily injections of Tamoxifen. Epithelium enriched (gut scrapes) samples of small intestine (jejunum) were collected at day 4 post induction. Loss of Brg1 expression in the small intestinal epithelium at this time point was confirmed by immunohistochemistry.

The cellular basis for epithelial-mesenchymal interaction during mouse tooth development

Project description:In this study, using mouse molar as the model, we developed a dual fluorescence reporter mouse to precisely track and analyze dental epithelium and mesenchyme at single-cell resolution from early embryonic to postnatal stages. Moreover, we constructed the virtual molar explorer (VMEx) to spatially map 15,967 molar-expressed genes and identified that Msx1+ Sdc1+ marked the developing dental papilla while surrounded by Msx1+ Sdc1- molar niche. Through tooth germ reconstitution and organoid culture in vitro and kidney capsule transplantation in vivo, we provided evidence that the Msx1+ Sdc1- dental follicle cells might function as the tooth organizers that promoted epithelium survival and tooth germ organization. Furthermore, the appearance of Msx1+ Sdc1+ dental papilla cells relied on the interaction between dental epithelium and Msx1+ Sdc1- dental follicle cells. Together, our results revealed the cellular dynamics of tooth development in mice and identified that the dental follicle might be the key driver of epithelial-mesenchymal interaction and tooth morphogenesis.
