Expression profile of PIK3R1 knockout and non-targeting control cells in response to Notch inhibition

ABSTRACT: To gain insights how loss of PIK3R1 confers resistance to pharmacological Notch inhibition in T-ALL cells, we performed gene expression analysis. Libraries for mRNA-seq were prepared with the Stranded mRNA Ligation method (Illumina) starting from 1µg RNA, according to manufacturer’s instructions. Libraries, all bearing unique dual indices, were subsequently loaded at 250pM in a HiSeq 4000 instrument (Illumina) and sequenced according to manufacturer’s instructions, yielding paired-end reads of 75 nucleotides. Reads were trimmed of their adapters with bcl2fastq v2.20 (Illumina) and quality-controlled with FastQC v0.11.9. PIK3R1 deficiency leads to up-regulation of cell cycle and pro-survival genes in response to Notch inhibition.

Transcriptome Analysis of Plasmodium CSP stable expressing or control A549 cells

Project description:To investigate the potential effect of overexpression of Plasmodium yoelii cirumsporozoite protein on A549 cells. Control and CSP stable expression A549 cells were constructed by infected with pLenti vector and pLenti-CSP plasmids and cultured with HBSS for 24h. Total RNA from Control and CSP stable expression A549 cells was extracted using the mirVana miRNA Isolation Kit (Ambion) following the manufacturer’s protocol. RNA integrity was evaluated using the Agilent 2100 Bioanalyzer (Agilent Technologies, Santa Clara, CA, USA). The samples with RNA Integrity Number (RIN) ≥ 7 were subjected to the subsequent analysis. The libraries were constructed using TruSeq Stranded mRNA LTSample Prep Kit (Illumina, San Diego, CA, USA) according to the manufacturer’s instructions. Then these libraries were sequenced on the Illumina sequencing platform (illumina novaseq6000) and 125bp/150bp paired-end reads were generated.

Project description:Purpose: Identification of glucocorticoid recepor binding sites on human kidney proximal tubular cells to better understand epigenetic alterations in diabetic kidney diseases Methods: CUT&RUN assay libraries for cultured cells or human kidneys were generated with the CUTANA kit (EpiCypher, 14-1048). 500,000 cells were mixed and incubated with Concanavalin A (ConA) conjugated paramagnetic beads. Antibodies to the glucocorticoid receptor were added to target samples and IgG was added to negative controls. The remaining steps were performed according to manufacturer’s instructions. Library preparation was performed using the NEBNext Ultra II DNA Library Prep Kit for Illumina (New England BioLabs, E7645S) with manufacturer’s instructions, including minor modifications indicated by CUTANA described above. CUT&RUN libraries were sequenced on a NovaSeq instrument (Illumina, 150 bp paired-end reads). For bulk ATAC-seq, 50,000 nuclei were transposed in 25 μL of ATAC-seq transposition mix [12.5 μL 2× Illumina Tagment DNA (TD) buffer; 10.5 μL nuclease-free water; 2.0 μL Tn5 transposase (Illumina/Nextera, FC-121-1030)] and incubated at 37°C for 1 h on a thermomixer.

Transcriptional profiling (RNA-seq) of wild-type and Arhgap35 knockout embryonic motor neurons (E12.5)

Project description:Ventral spinal cord regions micro-dissected from E12.5 Arhgap35 (aka, p190) knockout embryos or control littermates (wild-type or p190+/-) were pulled and dissociated with papain (Worthington Biochemical Cat# LK003153) according to the manufacturer’s instructions. Cells were sorted on a Becton Dickinson FACS Vantage SE DiVa using Coherent Sapphire 488 nm solid state laser and collected directly into RLT lysis buffer containing β-mercaptoethanol (Qiagen). RNA was isolated using the RNeasy Mini Kit (Qiagen) with on-column DNase digestion (Qiagen RNase-Free DNase Set). Each sample contained between 100,000 and 200,000 GFP+ motor neurons isolated from 2-5 spinal cords during a single experimental session. Five p190-/- and five control RNA samples were quantified with Agilent 2200 TapeStation system prior to preparation of mRNA-sequencing libraries (50 bp single-end) using the Illumina TruSeq RNA Library Preparation Kit (v2) according to the manufacturer’s instructions. Libraries were sequenced with Illumina HiSeq 2500 platform. "Negative" samples are from FACS-sorted Hb9:GFP-negative cells.

Postnatal loss of Arx transcriptional activity in parvalbumin interneurons induces epilepsy-like network abnormalities

Project description:We report the use to RNA-sequencing to understand the role of postnatal Arx in the regulation of PV interneuron function. Total RNA extracted from control and Arx CKO male mice cells were submitted to the Next-Generation Sequencing Core of the University of Pennsylvania for cDNA amplification, library preparation, and sequencing using the Ovation RNA-seq v2 and Rapid DR Multiplexing kits (NuGEN). Whole mRNAseq libraries were prepared from 9 mice (5 control and 4 Arx CKO mice) using the SMARTer Ultra Low RNA Kit for Illumina Sequencing (Clontech, Cat#634936) according to manufacturer’s instructions. Standard methods to assess sample quality (Agilent Bioanalyzer, Kappa Biosystems Library Quantification kit, Qubit® Fluorometer) and measure cDNA concentration were used. A total of 1ng of amplified cDNA for each sample was used as input to build the sequencing libraries. Whole mRNAseq libraries from control and Arx CKO mice were quantified using Agilent Bioanalyzer DNA 7500 chips. Libraries were sequenced on the Illumina HiSeq 4000 2 × 100 (Illumina, San Diego, CA, USA) to generate 150bp paired end reads, yielding approximately 20-40 million reads per sample (~80 million reads per lane).

Project description:Transcriptional analysis of the pancreatic islets of adult Paupar KO mice versus Paupar WT mice. Total RNA from Paupar WT and Paupar KO mice was converted into cDNA libraries (TruSeq RNA sample preparation kit, Illumina) according to manufacturer’s instructions. Sequencing was performed to a depth of 30 million, single-end reads in three biological replicates per genotype. Reads were aligned to the mouse genome (mm9) using HISAT2 v2.1.0 (Kim et al., 2013). Aligned reads were assigned to genes using annotations from Ensembl (Mus_musculus.GRCm38.73.gtf) and HTseq-count v0.10.0 (Anders et al., 2015). Differential expression across cohorts was assessed using DESeq2 v1.18 (Love, Huber, and Anders, 2014). Among the downregulated genes with a p-value < 0.05 genes important for alpha cell identity and function.
