Project description:Purpose: The aim of this study is to identify genes that are under the transcriptional control of the epigenetic regulator Smchd1 in neural stem cells (NSCs) derived from E14.5 mouse brain Methods: Total RNA was extracted using an AllPrep DNA/RNA Mini Kit (Qiagen) from cultured neural stem cells derived from male mouse E14.5 brains either wild-type or null for Smchd1. 1 µg total RNA was used to generate sequencing libraries for whole transcriptome analysis with Illumina’s TruSeq RNA Sample Preparation Kit v2 as per standard protocols. Libraries were sequenced on HiSeq 2000 with Illumina TruSeq SBS Kit v3-HS reagents as either 100 bp single-end or paired-end reads at the Australian Genome Research Facility (AGRF), Melbourne. Reads were aligned to the mouse reference genome mm10 and mapped to known genomic features at the gene level using the Rsubread package (version 1.10.5) (Liao et al. 2013). Mapped reads were then summarized into gene-level counts using FeatureCounts (Liao et al. 2014).

Project description:Purpose: The aim of this study is to determine the absolute and relative expression levels of mRNA transcripts across multiple flow cytometrically sorted epithelial cell types including freshly isolated CD24+CD29hi mammary stem cell-enriched basal cells (MaSC/basal), CD24+CD29loCD61+ luminal progenitor-enriched (LP) and the CD24+CD29loCD61- mature luminal-enriched (ML) cell populations. Additionally, a comparison between these primary cell types and cultured MaSC/Basal-derived mammosphere cells (mammosphere) and the CommaD-βGeo (CommaDβ) cell line was performed. Methods: Total RNA was extracted and purified from sorted luminal or basal populations from the mammary glands of female virgin 8- to 10-week-old FVB/N mice (3 independent samples per population), MaSC/Basal cells cultured for 1 week under mammosphere conditions and CommaDβ cells grown under maintenance conditions (Deugnier et al. 2006). Total RNA (100 ng) was used to generate sequencing libraries for whole transcriptome analysis following Illumina’s TruSeq RNA v2 sample preparation protocol. Completed libraries were sequenced on HiSeq 2000 with TruSeq SBS Kit v3- HS reagents (Illumina) as 100 bp single-end reads at the Australian Genome Research Facility (AGRF), Melbourne. Approximately 30 million 100 bp single-end reads were obtained for each sample. Reads were aligned to the mouse reference genome mm10 and mapped to known genomic features at the gene level using the Rsubread package (version 1.14.1) (Liao et al. 2013). Single reads were then summarized into gene-level counts using FeatureCounts (Liao et al. 2014).

Project description:Purpose: The aim of this study is to compare the transcriptome profiles of a limited number of lung cancer cell lines with the intention of selecting the two most similar cell lines for a mixture experiment (GSE64098). Methods - Cell Culture: Five lung adenocarcinoma cell lines (H2228, NCI-H1975, HCC827, H838 and A549) from a range of passages (2-4) were grown on 2 separate occasions in RPMI media (Gibco) supplemented with Glutamax and 10\% fetal calf serum to a 70\% confluence. To replicate common experimental conditions cell lines were treated with 0.01\% Dimethyl sulfoxide (Sigma), which is commonly used as a vehicle in drug treatment experiments. After 6 hours of treatment, cells were collected, snap-frozen on dry ice and stored at -80 degree C until required. Methods - RNA preparation: Total RNA was extracted from between half a million and million cells using Total RNA Purification Kit (Norgen Biotek) according to the kit instructions. RNA quality and concentration were assessed using Nanodrop and Tapestation RNA ScreenTape (Agilent) respectively. Methods - RNA-seq: 1 ug of total RNA from each sample were used for RNA-seq library preparation using TruSeq Total Stranded RNA with Ribozero (Illumina) according to manufacturer's instructions. Completed libraries were sequenced on HiSeq 2000 with TruSeq SBS Kit v3- HS reagents (Illumina) as 100 bp single end reads at the Australian Genome Research Facility (AGRF), Melbourne. We obtained on average 28 million for each sample (range from 25 to 29 million). Reads were aligned to the human reference genome hg19 using the Rsubread package (version 1.16.1) (Liao et al. 2013). Single reads were then summarized into gene-level counts using FeatureCounts in the reverse-stranded mode (Liao et al. 2014).

Project description:Purpose: The aim of this study is to compare different RNA extraction methods using a mixture design that allows the relative changes of the majority of genes profiled to be estimated. A number of samples were degraded to allow us to compare methods for dealing with more variable samples. Methods - Cell Culture: Lung adenocarcinoma cell lines NCI-H1975 and HCC827 from a range of passages (2-4) were grown on 3 separate occasions in RPMI media (Gibco) supplemented with Glutamax and 10% fetal calf serum to a 70% confluence. To replicate common experimental conditions cell lines were treated with 0.01% Dimethyl sulfoxide (Sigma), which is commonly used as a vehicle in drug treatment experiments. After 6 hours of treatment, cells were collected, snap-frozen on dry ice and stored at -80 degrees C until required. Methods - RNA preparation: Total RNA was extracted from between half a million and million cells using Total RNA Purification Kit (Norgen Biotek) with on-column DNAse treatment accorting to the kit instructions. RNA concentration for each pair of samples to be mixed was equalised to ~100 ng/μl using Qubit RNA BR Assay Kit (Life Technologies). Replicates were pooled in known proportions to obtain mixtures ranging from pure NCI-H1975 (100:0) to pure HCC827 (0:100) and intermediate mixtures ranging from 75:25 to 50:50 to 25:75 NCI-H1975:HCC827. All mixtures corresponding to the second replicate were split into two equal aliquots. One aliquot was left intact (we refer to this as the 'good' replicate), while the second aliquot was degraded to produce known outlier samples by incubation at 37 degrees C for 7 days in a thermal cycler with a heated lid. 10 μl from each replicated mixture (both good and degraded) were used for Next Generation Sequencing library preparation using two kits: Illumina TruSeq Total Stranded RNA with Ribozero (TotalRNA) and Illumina TruSeq RNA v2 (mRNA) according to the manufacturer's instructions. Completed libraries were sequenced on HiSeq 2500 with TruSeq SBS Kit v4- HS reagents (Illumina) as 100 bp single-end reads at the Australian Genome Research Facility (AGRF), Melbourne. Approximately 30 million 100 bp single-end reads were obtained for each sample. Reads were aligned to the human reference genome hg19 and mapped to known genomic features at the gene level using the Rsubread package (version 1.16.1) (Liao et al. 2013). Single reads were then summarized into gene-level counts using FeatureCounts (Liao et al. 2014).

Project description:We used our newly ultra deep sequence data and bioinformatics to re-annotate P. xylostella genome for high confidence miRNAs with the correct 5p and 3p arm features. Furthermore, the whole genome was screened to identify potential miRNA binding sites using three target-predicting algorithms. Totally, 203 mature miRNAs were annotated, including 33 novel miRNAs. Two geographical populations of Diamondback moth larvae from Queensland (Gatton) and South Australia (Waite) were collected and reared on the cabbage plant at the University of Queensland in Australia. Total RNA was extracted from fifteen 3rd instar larval samples using Triazol® following the manufacturerâs protocol (Life Technologies). The small RNA libraries were generated from both populations with three biological replicates using the Illumina Truseq small RNA preparation kit at the Australian Genome Research Facility (AGRF-Melbourne, Australia). The purified cDNA libraries were sequenced on Illumina HiSeq and raw sequencing reads (50 nt) were obtained using Illuminaâs Sequencing Control Studio software.

Project description:Purpose: The aim of this study is (1) to identify the chromatin occupancy of the epigenetic regulator Smchd1 in neural stem cells (NSCs) derived from E14.5 mouse brain; (2) to profile key epigenetic marks H3K4me3, H3K27me3 and DNA methylation in wild type and Smchd1 null NSCs; (3) to identify the chromatin occupancy of Ctcf in wild type and Smchd1 null NSCs. Methods: Chromatin immunoprecipitation for Smchd1, H3K4me3, H3K27me3 and Ctcf was performed essentially as in (Nelson et al. 2006). Briefly, nuclei were isolated from formaldehyde crosslinked NSCs and chromatin was fragmented by sonication. Chromatin immunoprecipitation was performed with corresponding antibodies for Smchd1, H3K4me3 and H3K27me3. DNA was extracted from the immunoprecipitated fraction following reverse-crosslinking. Isolated DNA was used to generate sequencing libraries with Illumina's TruSeq DNA Sample Preparation Kit or Ovation Ultralow system (NuGen) according to manufacturer's instruction. Libraries were pooled and sequenced on the Illumina HiSeq 2000 platform for 100 bp single-end reads. Image analysis was performed in real time by the HiSeq Control Software (HCS) v1.4.8 and Real Time Analysis (RTA) v1.12.4.2, running on the instrument computer. Real-time base calling on the HiSeq instrument computer was performed with the RTA software. Illumina CASAVA1.8 pipeline was used to generate the sequence data. To examine the level of DNA methylation, genomic DNA was extracted using an AllPrep DNA/RNA Mini Kit (Qiagen) and methylated DNA was isolated via binding to the methyl-CpG binding domain of human MBD2 protein coupled beads using the MethylMiner methylated DNA enrichment kit (Life Technologies) according to the manufacturer’s instructions. Isolated DNA was used to generate sequencing libraries as for the ChIP-seq experiment with Illumina’s TruSeq DNA Sample Preparation Kit according to manufacturer's instruction and sequenced on the Illumina HiSeq 2000 platform for 49 bp single-end reads. Sequencing analysis was performed as described for the ChIP-seq experiments.

Project description:Purpose: The aim of this study is to explore histone modification in four basal cell populations defined by Lgr5 and Tspan8 expression taken from adult mouse mammary glands using chromatin immunoprecipitation sequencing (ChIP-seq). Methods: The ChIP DNA samples were prepared and indexed for Ilumina sequencing using the TruSeq DNA sample Prep Kit (Ilumina) as per manufacturer's instruction. The library was quantified using the Agilent Tapestation and the Qubit's RNA assay kit for Qubit 2.0 Fluorometer (Life Technologies). The indexed libraries were then prepared for paired-end 75bp sequencing on a NextSeq500 instrument using the 150 cycle kit v2 chemistry (Ilumina) as per manufacturer's instructions. Reads were aligned to the mouse genome (mm10) using the subread algorithm by Liao et al. (2013) and counted into bins associated with Entrez gene identifiers (27080 genes in total) using featureCounts in two different ways. Genebody counts summarised the number of reads overlapping anywhere between the first and last base of a given gene while promoter counts summarized the number of reads overlapping a region 3000 bases upstream to 2000 bases downstream of the TSS of each gene. For downstream analysis, genebody counts were used for the H3K27me3 marks and promoter counts were used for the H3K4me3 marks.
