Project description:microRNA profiling of rat small intestinal crypt cell IEC-6. Comparing control untreated with cells treated with transforming growth factor-beta (TGF-beta). TGF-beta stimulated cell differentiation, as observed in the stimulation of intestinal epithelial cell markers (alkaline phophotase, villin, aminopeptidase N, etc.). Two condition experiment. Control vs TGF-beta treatment. Biological replicates: 3 control, 3 treated. Independently grown and harvested. One replicate per array

Project description:A series of two color gene expression profiles obtained using Agilent 44K expression microarrays was used to examine sex-dependent and growth hormone-dependent differences in gene expression in rat liver. This series is comprised of pools of RNA prepared from untreated male and female rat liver, hypophysectomized (‘Hypox’) male and female rat liver, and from livers of Hypox male rats treated with either a single injection of growth hormone and then killed 30, 60, or 90 min later, or from livers of Hypox male rats treated with two growth hormone injections spaced 3 or 4 hr apart and killed 30 min after the second injection. The pools were paired to generate the following 6 direct microarray comparisons: 1) untreated male liver vs. untreated female liver; 2) Hypox male liver vs. untreated male liver; 3) Hypox female liver vs. untreated female liver; 4) Hypox male liver vs. Hypox female liver; 5) Hypox male liver + 1 growth hormone injection vs. Hypox male liver; and 6) Hypox male liver + 2 growth hormone injections vs. Hypox male liver. A comparison of untreated male liver and untreated female liver liver gene expression profiles showed that of the genes that showed significant expression differences in at least one of the 6 data sets, 25% were sex-specific. Moreover, sex specificity was lost for 88% of the male-specific genes and 94% of the female-specific genes following hypophysectomy. 25-31% of the sex-specific genes whose expression is altered by hypophysectomy responded to short-term growth hormone treatment in hypox male liver. 18-19% of the sex-specific genes whose expression decreased following hypophysectomy were up-regulated after either one or two growth hormone injections. Finally, growth hormone suppressed 24-36% of the sex-specific genes whose expression was up-regulated following hypophysectomy, indicating that growth hormone acts via both positive and negative regulatory mechanisms to establish and maintain the sex specificity of liver gene expression.

Project description:Depending on the tumor type IκB kinase α (IKKα) can act as tumor promoter or tumor suppressor in various malignancies. Here we demonstrate a key function of IKKα in the suppression of a tumoricidal microenvironment during intestinal carcinogenesis. Mice deficient in IKKα kinase activity are largely protected from intestinal tumor development that is dependent on the enhanced recruitment of IFNγ expressing M1-like myeloid cells. In IKKα mutant mice M1-like polarization is not controlled in a cell autonomous manner but depends rather on the interplay of both IKKα mutant tumor epithelia and immune cells. Tamoxifen-inducible β-catc.a. mice comprise an excellent model to study Wnt-dependent tumor initiation. These mice are characterized by IEC-restricted stabilization of β-catenin causing rapid expansion of intestinal crypts and loss of differentiated IEC. To further explore the underlying IKKα controlled pro-proliferative mechanism, we performed a microarray analysis comparing RNA isolated from wildtype, IkkαAA/AA, β-catc.a. or β-catc.a./IkkαAA/AA IEC 15 days after the first tamoxifen administration. and within 4 weeks β-catc.a. mice succumb to this marked crypt hyperproliferation
