Project description:This study annotates the NGS reads in ICC and Sm Int sncRNA libraries. In addition to known sncRNAs, we identified numerous somatic piRNA-like RNAs. This study confirms the expression of pilRNAs in somatic tissues and outlines their major characteristics. ICC and Sm Int were collected from adult mice (C57BL/6). Small RNA was isolated from samples and cDNA libraries were generated for 454 sequencing. Sequences from FastA files were aligned to known sncRNA and the mouse mm9 genome. This was followed by subsequent novel small RNA annotation.

Project description:Interstitial cells of Cajal (ICC) have important functions in regulation of motor activity in the gastrointestinal tract. In murine small intestine ICC are gathered in the region of the myenteric plexus (ICC-MY) and within the deep-muscular plexus near the submucosal surface of the circular muscle layer (ICC-DMP). These two classes of ICC have different physiological functions. ICC-MY are pacemaker cells and generate the slow wave electrical rhythmicity of gastrointestinal organs. ICC-DMP form synaptic connections with the varicose nerve terminals of enteric motor neurons and are involved in reception and transduction of motor neurotransmission. In the present study we used recently developed highly selective techniques to isolate the two classes of ICC from enzymatically dispersed intestinal muscles by fluorescence-activated cell sorting. Transcriptional expression of the two functional classes was investigated using DNA microarray analysis. Experiment Overall Design: ICC-DMP and ICC-MY cells were isolated from the murine small intestinal tissues and their transcriptional expression was compared with that of the tunica muscularis tissues. Transcriptional expression profiles of ICC-DMP and ICC-MY were compared to each other also.

Project description:GIST is considered to invariably arise through gain-of-function KIT or PDGFRA mutation of the interstitial cells of Cajal (ICC). However, the genetic basis of the malignant progression of GIST is poorly understood. We analysed the expression levels of 54,613 probe sets in 32 surgical samples of untreated GIST of the stomach and small intestine with GeneChip Human Genome U133 Plus 2.0 arrays. Keywords: gene expression array-based, count

We analysed the expression levels of 54,613 probe sets in 32 surgical samples of untreated GIST of the stomach and small intestine with GeneChip Human Genome U133 Plus 2.0 arrays. Experiment Overall Design: Total RNA was extracted from 32 fresh frozen tumour specimens. We analysed the global gene exprssion profiles of these GIST cases in order to clarify the genomic basis behind the malignant progression of this tumor

Project description:Gastrointestinal (GI) motility disorders affect millions of people worldwide, yet remain poorly treated due to insufficient knowledge of the molecular networks controlling GI motility. Interstitial cells of Cajal (ICC) are critical GI pacemaker cells, and abnormalities in ICC are implicated in GI motility disorders. Nevertheless, human ICC are poorly characterised, largely due to difficulties in accessing sufficient numbers for research. Two cell surface proteins have been identified as ICC markers: the receptor tyrosine kinase, KIT; and the calcium-activated chloride channel, Anoctamin-1 (ANO1). Anti-KIT antibodies have been used to purify mouse ICC via flow cytometry. Here, we performed single-cell RNA sequencing of KIT-sorted, primary human gastric ICC to better understand networks controlling human ICC biology.

Project description:Gastrointestinal stromal tumors (GIST) are thought to derive from the interstitial cells of Cajal (ICC) or an ICC precursor. Oncogenic mutations of the receptor tyrosine kinase KIT are present in most GIST. KIT K642E was originally identified in sporadic GIST and later found in the germ line of a familial GIST. A mouse model of harboring a germline Kit K641E mutant was created to model familial GIST. The expression profile was investigated in the gastric antrum in the knock-in Kit K641E murine GIST model by microarray.

Project description:Genome scale expression data on absolute numbers of gene isoforms offer essential clues for cellular functions and biological processes. Gastrointestinal (GI) motility is regulated by smooth muscle cells (SMC) closely contacted with interstitial cells of Cajal (ICC) and fibroblast-like PDGFRα+ cells (PαC), forming an electrical syncytium. To uncover genetic identifies and cellular functions of the cells, we isolated these three cell populations from mouse small intestine and colon, obtained the transcriptome for each type of cells, and built each cell type transcriptome browser. To our knowledge, this is the first genetic resource providing a comprehensive reference for all mRNA transcripts expressed in these unique GI cell populations. Integration of these data with the UCSC genome browser revealed novel cell-specific markers, ion channel and transporter isoforms, and unique cellular and biological functions of these cells in GI physiology. Our transcriptome browsers bring new insight into the alternative expression of genes in different types of the cells and provides references for future functional studies. mRNA profiles of SMC, ICC and PDGFRa cells isolated from mouse jejunum and colon were generated by deep sequencing using Illumina Hiseq2000..
