SLIC-CAGE of paired-end sequencing data in mouse islets

ABSTRACT: Super-Low Input Carrier Cap Analysis of Gene Expression (SLIC-CAGE) to identify transcription start sites (TSS) and existing genome-wide maps of islet histone marks to characterise the contribution of transcriptional regulation of LKB1-mediated control of gene expression in mouse β-cells. SLIC-CAGE was performed as in (Cvetesic et al. - doi: 10.1101/gr.235937.118) using 100 ng of total RNA extracted as described above from islets isolated from a 18 week old female mouse on a C57BL6/J background. 12 cycles were performed for library amplification. The amplified library was purified with AMPure XP beads and visualised using a HS DNA chip (Bioanalyzer, Agilent). The library was sequenced on a HiSeq2500 instrument with paired-end, 150bp reads). SLIC-CAGE paired-end sequencing data was aligned to GENCODE assembly annotation version GRCm38.p6 using the STAR alignment tool v2.4.2a.

A miR-494 dependent feedback loop regulates ER stress (ANAN-376 Project)

Project description:Defects in stress responses are important contributors in many chronic conditions including cancer, cardiovascular disease, diabetes, and obesity-driven pathologies like non-alcoholic steatohepatitis (NASH). Specifically, endoplasmic reticulum (ER) stress is linked with these pathologies and control of ER stress can ameliorate tissue damage. MicroRNAs have a critical role in regulating diverse stress responses including ER stress. Here we show that miR-494-3p plays a functional role during ER stress. ER stress inducers (tunicamycin and thapsigargin) robustly increase the expression of miR-494 in vitro in an ATF6 dependent manner. Surprisingly, miR-494 pretreatment dampens the induction and magnitude of ER stress in response to tunicamycin in endothelial cells. Conversely, inhibition of miR-494 increases ER stress de novo and amplifies the effects of ER stress inducers. Using Mass Spectrometry (TMT-MS) we identified many proteins that are downregulated by both tunicamycin and miR-494 in cultured human umbilical vein endothelial cells (HUVECs). Among these, we found 6 transcripts which harbor a putative miR-494 binding site. Our data indicates that ER stress driven miR-494 may act in a feedback inhibitory loop to dampen downstream ER stress signaling. We propose that RNA-based approaches targeting miR-494 or its targets may be attractive candidates for inhibiting ER stress dependent pathologies in human disease.

Regional Differences in gene expression and promoter usage in aged human brains

Project description:Cap analysis of gene expression (CAGE) and massive parallel sequencing were used to profile the promoterome of aged human brains from five regions, namely: caudate, frontal cortex, hippocampus, putamen and temporal cortex. 25 RNA libraries from post-mortem brain tissue (five caudate, five frontal, 5 hippocampus, 5 putamen, five temporal RNA libraries from seven individuals) were processed using CAGE protocol and CAGE tags derived from the 25 libraries were sequenced with Illumina.

SLIC-CAGE (Super-Low Input Carrier-CAGE) development: comparison with Saccharomyces cerevisiae nAnTi-CAGE and nanoCAGE libraries and validation of SLIC-CAGE on Mus musculus total RNA

Project description:We developed SLIC-CAGE (Super-Low Input Carrier-CAGE) approach to capture 5'end of RNA polymerase II transcripts from as little as 5-10 ng of total RNA. The dramatic increase in sensitivity compared to existing CAGE methods is achieved by specially designed, selectively degradable carrier RNA. We tested SLIC-CAGE on Saccharomyces cerevisiae (BY4741 strain) and produced libraries from 1-100 ng of total cellular RNA. We also produced S. cerevisiae nAnT-iCAGE libraries as the current gold-standard CAGE libraries using the recommended 5 micrograms of total cellular RNA to assess the quality of SLIC-CAGE libraries produces with up to 1000-fold less material. We provide a direct comparison between SLIC-CAGE and the latest nanoCAGE protocol (libraries created using S. cerevisiae total RNA) and show that SLIC-CAGE produces unbiased libraries of higher complexity and quality than nanoCAGE. Finally, we provide SLIC-CAGE libraries on mouse embryonic stem cells (E14) using 5-100 ng of total cellular RNA as starting material.

Nuclear SLIC-CAGE of human cortical neurons from Cornelia de Lange Syndrome patients and control individuals

Project description:We used SLIC-CAGE to map transcriptional start sites in cortical neurons from Cornelia de Lange Syndrome (CdLS) patients and control individuals. SLIC-CAGE was performed using nuclear RNA isolated from pre-frontal cortical grey matter. Usage of nuclear RNA allows enrichment of unstable RNAs, such as RNA originating from enhancer transcription. We characterised promoter-level gene expression in cortical neurons from CdLS patients and found deregulation of hundreds of genes enriched for neuronal functions.

miRNA and consolidation of cued fear memory

Project description:miRNA profiling was carried out using the miRCURY LNA™ microRNA Array (6th gen - hsa, mmu & rno) miRNA were profiled in amygdala brain tissue obtained from adult mice 30 mins after auditory fear conditioning and expression levels compared to tissue obtained from Home cage controls Adult male mice were fear conditioned using tone-shock pairings and brains were harvested 30 mins later. The brains of Home Cage controls and Fear Conditioned animals (n = 4/group) were then punched to collect amygdala tissue. miRNA were extracted using the Qiagen miRNeasy Kit, and then shipped to Exiqon. Exiqon performed labeling, hybridization and data analysis after use of the miRCURY LNA™ microRNA Array (6th gen - hsa, mmu & rno). https://www.exiqon.com/ls/Documents/Scientific/miRCURY-LNA-microRNA-Array-6th-gen-hsa-mmu-rno-manual.pdf

MicroRNA expression profiling of human pancreatic islets reveals microRNAs with altered expression due to glyceamic status

Project description:Global microRNA (miRNA) profiling was performed in 18 human islet donors using Exiqon’s LNA (locked nucleic acid)-based array platform. Donors were divided into three groups according to their HbA1c levels and type-2 diabetes diagnosis (normal glucose tolerance - NGT, impaired glucose tolerance - IGT, diagnosed with type-2 diabetes-T2D). To identify miRNAs with altered expression due to glyceamic status, donors were matched for age, gender and BMI and differential expression analysis was performed in 7 NGT vs 7 IGT/T2D donors using Significance Analysis of Microarrays (SAM) based on False Discovery Rate (FDR) statistics.
