Project description:Total RNA was isolated from serum samples by the Qiagen miRNeasy Serum/Plasma extraction kit and QIAcube automation. All samples were quantified using the Nanodrop spectrophotometer prior to plating. Small RNA-seq libraries were prepared using the Norgen Biotek Small RNA Library Prep Kit and then sequenced on the Illumina NextSeq 500 platform at 51bp single end reads. ExceRpt was employed to assess the read quality and annotate miRNAs. The read count was log transformed and normalized by quantile normalization.

Project description:Inactivation of prospero in Drosophila neuroblasts during larval stages induces unlimited neuroblast amplification leading to tumors that persist growing in adults. Tumors present in the ventral nerve cord of adult flies were dissected, dissociated and GFP-labelled tumor neuroblasts were isolated by FACS. 10000 neuroblasts were then processed for single-cell RNA-seq analysis. Single Cell RNA sequencing library were generated using the 10x Genomics Chromium Platform and sequenced on the Illumina Nextseq 500. eLife 2019;8:e50375 DOI: 10.7554/eLife.50375

Project description:Small RNA (<100 bases in length) were purified from total RNA using miRNeasy kit (Qiagen), then sequenced. Libraries were prepared at the Genomics Platform of the Cochin Institute, following the TruSeq small RNA protocol (Illumina), starting from 1 µg of high quality total RNA. Single read (1 × 75 bp) sequencing was performed on a Nextseq 500 platform (Illumina). FASTQ sequences were aligned on miRBase v.2052, then counted with STAR (v.2.5.2a). Counts were normalized with DESeq v1.30.0

Project description:The tumorigenesis of small intestinal neuroendocrine tumors (NETs) is poorly understood. Recent studies have associated alternative polyadenylation with proliferation, cell transformation and cancer. Polyadenylation is the process in which the pre-mRNA is cleaved at a polyA site and a polyA tail is added. Genes with two or more polyA sites can undergo alternative polyadenylation. This produces two or more distinct mRNA isoforms with different 3M-bM-^@M-^Y untranslated regions. Additionally, alternative polyadenylation can also produce mRNAs containing different 3M-bM-^@M-^Y-terminal coding regions. Therefore, alternative polyadenylation alters both the repertoire and the expression level of proteins. Here we used high-throughput sequencing data to map polyA sites and characterize polyadenylation genome-wide in three small intestinal neuroendocrine tumors and a reference sample. In the tumors sixteen genes showed significant changes of alternative polyadenylation pattern, which lead to either the 3M-bM-^@M-^Y truncation of mRNA coding regions or 3M-bM-^@M-^Y untranslated regions. Among these, 11 genes had been previously associated with cancer, with 4 genes being known tumor suppressors: DCC, PDZD2, MAGI1 and DACT2. We validated the alternative polyadenylation in 3 out of 3 cases with Q-RT-PCR. Our findings suggest that changes of alternative polyadenylation pattern in these 16 genes could be involved in the tumorigenesis of small intestinal neuroendocrine tumors. Furthermore, they also point to alternative polyadenylation as a new target for both diagnostic and treatment of small intestinal neuroendocrine tumors. The identified genes with alternative polyadenylation specific to the small intestinal neuroendocrine tumors could be further tested as diagnostic markers and drug targets for disease prevention and treatment.

Project description:Purpose: the effects of a gastrin receptor antagonist has been studies in patients with gastrin neuroendocrine (NE) tumours due to hypergastrinemia. This mouse model of hypergastrinemia is a model for studying long term acid inhibition, including NE hyperplasia and formation of Spasmolytic polypeptide expressing metaplasia (SPEM), a proposed premalignant alteration of the stomach. Methods: RNA was isolated from the oxyntic mucosa. RNA was sequenced using standard Illumina protocols on a NextSeq 500 instrument. Results: NTZ reduced oxyntic mucosal hypertropohy and stomach weight. Neuroendocrine cell hyperplasia and NE markers were also reduced. Spasmolytic polypeptide expressing metaplasia (SPEM) was expressed in KO mice and was not affected by the gastrin receptor antagonist. Conclusions: The gastrin receptor antagonist YF reduced gastric corpus mucosal hypertrophy and NE cell hyperplasia in HKATPase KO mice, but did not affect SPEM or SPEM related genes.
