Expression data from laser microdissected murine intestinal epithelial cells

ABSTRACT: Microarray analyses of laser microdissected murine intestinal epithelial cells under the control of maternal inflammation at 17.5 days post conception demonstrates that maternal inflammation differentially regulates 2174 (iWT) and 3345 (iARE) genes in fetal tissue, but these transcriptional profiles were overwritten in the postnatal environment dominated by tissue inflammation at 8 weeks postnatal. We isolated 50 ng total RNA out of laser microdissected fetal and adult intestinal epithelial cells from the distal ileum and performed microarrays to address whether maternal inflammation programs the fetal intestine towards TNF-driven pathology

Female Tnf+/+ wild type (WT) mice were bred with male TnfM-NM-^TARE/+ (ARE) mice and vice versa, generating offspring from healthy WT dams (WT and ARE) and inflamed ARE dams (iWT and iARE). On day 17.5 post conception (dpc) and 8 weeks postnatal the fetuses and offspring were sacrificed.The gut was freshly frozen in Optimal Cutting Temperature (O.C.T.) embedding compound (Sakura Finetek, Torrance, USA) on dry ice and stored at -80M-BM-0C until laser microdissection.

Gene expression profiling of laser capture microdissected prostate specimens

Project description:We performed gene expression profiling of laser capture microdissected normal non-neoplastic prostate (cystoprostatectomies) epithelial tissue and compared it to non-transformed and neoplastic low and high grade prostate epithelial tissue from radical prostatectomies, each with its immediately surrounding stroma.

Gene expression of ulcer-associated cell lineage

Project description:We applied RNA-seq analysis of total RNA isolated from laser capture microdissected intestinal epithelium. The analysis aimed at charactericing the gene expression seen in ulcer-associated cell lineage epithelial cells, and to contrast this with that of healthy control epithelium and epithelium from inflammatory bowel disease-patients with active inflammation.

Gene expression profiles obtained from laser-microdissected human choroid plexus papilloma cells

Project description:Gene expression profiles generated from human tumor cells laser-microdissected from surgical samples of seven choroid plexus papillomas (Grade I WHO) as eight samples of epithelial cells lasermicrodissected from normal choroid plexus obtained at autopsy.

Proteomic analysis of laser-microdissected murine fetal glomeruli

Project description:Alteration of fetal kidney morphogenesis in diabetic pregnancies is poorly described, especially changes in the extracellular matrix (ECM) and glomerular basement membrane (GBM) during glomerulogenesis. Addressing the ECM proteome, or matrisome, in mouse fetal glomeruli in a healthy and diabetic environment will improve understanding about the association between ECM and GBM changes in the glomerulus as potential reprogramming mechanisms for glomerular dysfunction in infants of mothers with diabetes. This project aimed to define the matrisome and BM composition in the maturing murine fetal glomeruli collected from normal and diabetic mothers. For this, we used laser microdissection microscopy to isolate maturing glomeruli from cryosections, and analyse by label-free tandem mass spectrometry to test the hypothesis that maternal diabetes influences ECM and GBM composition, assembly and function.

Microdissected tumor epithelium and tumor stroma from patients with breast cancer

Project description:Stratification of breast cancers into subtypes are generally based on immune assays on tumor cells and/or mRNA expression of tumor cell enriched tissues. Here, we have laser microdissected tumor epithelium and tumor stroma from 24 breast cancer biopsies (12 luminal-like and 12 basal-like). We hypothesized that the stromal proteome would separate patients with breast into groups independently of the traditional epithelial based subtypes.

Gene expression profile of microdissected mucinous ovarian tumors

Project description:Gene expression profile of 8 mucinous borderline ovarian tumors and 9 mucinous ovarian carcinomas. Frozen tumor samples were laser-capture microdissected for their epithelial component. RNA was extracted. Gene expression profiling was completed using Affymetrix U133 Plus 2.0 oligonucleotide microarrays.
