RNAseq analysis of the duodenum of intestine-specific adult SD mutant mice

ABSTRACT: Aim: Transcriptional analysis of the duodenum of adult Nkx2.2flox/SD;Villin-Cre (SDint) mice versus control Methods: 2 cm of the duodenum (as measured from the stomach) of 6 week old control and mutant mice were dissected and total RNA extracted. Libraries were prepared from total RNA (RIN>8) with the TruSeq RNA prep kit (Illumina) and sequenced using the HiSeq2000 (Illumina) instrument. More than 20 million reads were mapped to the mouse genome (UCSC/mm9) using Tophat (version 2.0.4) with 4 mismatches and 10 maximum multiple hits. Significantly differentially expressed genes were calculated using DEseq. Results: 206 genes with a p-value <0.05 were significantly changed. Among these are some enteroendocrine hormones. Conclusion: The SD domain of Nkx2.2 regulates specification of some enteroendocrine cells mRNA profiles of the duodenum of 6 week old control and SDint mice were generated by deep sequencing, in triplicate, using Illumina HiSeq2000.

RNA-Seq analysis of E15.5 pancreas of both whole body Nkx2.2 mutant embryos and endocrine progenitor specific Nkx2.2 mutant embryos

Project description:Aim: Transcriptional analysis of E15.5 whole pancreas of Nkx2.2-LacZ/LacZ embryos versus control and Ngn3-Cre; Nkx2.2-flox/flox embryos versus control Methods: Embryonic pancreata were isolated at E15.5 from Nkx2.2 mutant mice and controls. Total RNA was extracted. Libraries were prepared from total RNA (RIN>8) with the TruSeq RNA prep kit (Illumina) and sequenced using the HiSeq2000 (Illumina) instrument. More than 20 million reads were mapped to the mouse genome (UCSC/mm9) using Tophat (version 2.0.4) with 4 mismatches and 10 maximum multiple hits. Significantly differentially expressed genes were calculated using DEseq. Results: There is significant overlap between the differentially expressed genes of whole body Nkx2.2 mutant embryos and endocrine progenitor specific Nkx2.2 mutant embryos; many of the downregulated genes (p-value < 0.05) are genes involved in beta cell function. Conclusion: Nkx2.2 functions within the endocrine progenitor lineage to activate beta cell genes

Global profiling of Nkx2.2 SD-domain mutant pancreas during development and adulthood compared to transcriptional profiling of SD-domain mutant expressing neural progenitors.

Project description:The consolidation of unambiguous cell fate commitment relies on the ability of transcription factors (TFs) to exert tissue-specific regulation of complex genetic networks. The mechanisms by which TFs establish such precise control over gene expression, however, have remained elusive—especially in instances where a single TF operates in two or more discrete cellular systems. In this study, we demonstrate that  cell specific functions of NKX2.2 are driven by the highly conserved NK2-Specific Domain (SD). Mutation of the endogenous NKX2.2 SD domain prevents the developmental progression of beta cell precursors into mature, insulin-expressing beta cells, resulting in overt neonatal diabetes. Within the adult beta cell, the SD domain stimulates beta cell performance through the activation and repression of a subset of NKX2.2-regulated transcripts critical for beta cell function. These irregularities in beta cell gene expression may be mediated via SD domain-contingent interactions with components of the nuclear pore complex. In stark contrast to these pancreatic phenotypes, however, the SD domain is entirely dispensable for the development of NKX2.2-dependent cell types within the CNS. Together, these results reveal a previously undetermined mechanism through which NKX2.2 directs disparate transcriptional programs in the pancreas vs. neuroepithelium.
