LSD1 and CoREST2 Regulate STAT3 Activity to Promote Enteroendocrine Cell Differentiation in Mucinous Colorectal Cancer[scMultiome-seq]

Project description:Neuroendocrine cells have been implicated in therapeutic resistance and worse overall survival in many cancer types. Mucinous colorectal cancer (mCRC) is uniquely enriched for enteroendocrine cells (EECs), the neuroendocrine cell of the normal colon epithelium, as compared to non-mucinous CRC. Therefore, targeting EEC differentiation may have clinical value in mCRC. Here, single cell multi-omics was used to uncover epigenetic alterations that accompany EEC differentiation, identify STAT3 as a novel regulator of EEC specification, and discover a rare cancer-specific cell type with enteric neuron-like characteristics. Further experiments demonstrated that lysine-specific demethylase 1 (LSD1) and CoREST2 mediate STAT3 demethylation and regulate STAT3 chromatin binding. Knockdown of CoREST2 in an orthotopic xenograft mouse model resulted in decreased primary tumor growth and lung metastases. In culmination, these results provide rationale for new LSD1 inhibitors that target the interaction between LSD1 with STAT3 or CoREST2, which may improve clinical outcomes for patients with mCRC.

RNA-Seq analysis of mouse small intestine enteroendocrine cells

Project description:We generated knock-in mice expressing GFP under the control of the endogenous GIP (Glucose-dependent Insulinotropic Polypeptide) promoter that enable the isolation of a purified population of small intestine K cells. Using RNA-Seq, we comprehensively characterized the transcriptomes of GIP-GFP cells as well as the entire enteroendocrine lineage derived from Neurogenin3 (Ngn3)-expressing progenitors. We interrogated the whole transcriptome of FACS-isolated small intestine GIPGFP cells using high-throughput mRNA sequencing. We also obtained the global gene expression patterns of the entire enteroendocrine cell lineage as well as the non-enteroendocrine cell population, comprising enterocytes, goblet cells and Paneth cells. To achieve this, small intestine epithelial cells from male mice resulting from the breeding of Neurogenin3 (Ngn3)-Cre mice with ROSA26-LoxP-STOP-LoxP-tomato indicator mice were isolated based on Tomato fluorescence and negative staining for CD45. Due to the small cell numbers, we constructed each of the three RNA-Seq libraries (GIPGFP, Ngn3TOMATO, and Ngn3-) using a pool of equal amounts of individual RNA samples without RNA amplification.

Proteome profiling of mucinous and non-mucinous colorectal cancer

Project description:Mucus is associated with poor prognosis of colorectal cancer, but its mechanism remains unclear. The aim of this study was to reveal the key proteins in mucinous colorectal cancer. In this study, high-resolution liquid chromatography tandem mass spectrometry (LC-MS / MS) combined with quantitative 6-plex tandem mass mass tag labeling was used to profile protein changes in the left and right sides of mucinous and non-mucinous colorectal cancer tissues. A total of 7432 proteins were identified and analyzed.

Expression data of mouse mucinous lung tumors

Project description:Transgenic mice (Scgb1a1-rtTA/[tetO]-KRAS.G12D/Nkx2-1+/-) develop mucinous lung tumors. Gene expression analysis was performed using mRNAs from the whole lungs of the mice compared to that of the control mice. We used microarrays to detail the global program of gene expression underlying development of mucinous lung tumors and identified distinct classes of up-regulated genes during this process. mRNAs were isolated from the whole lungs of the transgenic mice (Scgb1a1-rtTA/[tetO]-KRAS.G12D/Nkx2-1+/-) after 2 months doxycycline administration and hybridized on Affymetrix microarrays. We sought to identify genes induced in mucinous lung tumors.

scMultiome analysis identifies embryonic hindbrain progenitors with mixed rhombomere identities

Project description:Rhombomeres serve to position neural progenitors in the embryonic hindbrain, thereby ensuring appropriate neural circuit formation, but the molecular identities of individual rhombomeres and the mechanism whereby they form have not been fully established. Here we apply scMultiome analysis in zebrafish to molecularly resolve all rhombomeres for the first time. We find that rhombomeres become molecularly distinct between 10hpf (end of gastrulation) and 13hpf (early segmentation). While the mature hindbrain consists of alternating odd- versus even-type rhombomeres, our scMultiome analyses do not detect extensive odd versus even characteristics in the early hindbrain. Instead, we find that each rhombomere displays a unique gene expression and chromatin profile. Prior to the appearance of distinct rhombomeres, we detect three hindbrain progenitor clusters (PHPDs) that correlate with the earliest visually observed segments in the hindbrain primordium and that represent prospective rhombomere r2/r3 (possibly including r1), r4 and r5/r6, respectively. We further find that the PHPDs form in response to Fgf and RA morphogens and that individual PHPD cells co-express markers of multiple mature rhombomeres. We propose that the PHPDs contain mixed-identity progenitors and that their subdivision into individual mature rhombomeres requires resolution of these mixed-identity cell states.

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.

Analysis of miRNA profiles in mucinous ovarian cancer cells that silenced PRKRA.

Project description:We compared miRNAs expression in mucinous ovarian cancer cell between treated with siPRKRA and contrl siRNA. We hypothesize that PRKRA regulates chemosensitivity in mucinous ovarian cancer. Therefore, we aim to idetify the PRKRA-mediated miRNA which regulate chemosensitivity in mucinous ovarian cancer.
