Elucidating the microRNA-203 specific biological processes in glioblastoma cells from comprehensive high-throughput RNA-sequencing transcriptome profiling

ABSTRACT: We report the application of high-throughput RNA-sequencing Profile of miR-203 expressing glioma U251 cells. Glioblastoma (GBM) is the most common primary malignant intracranial adult brain tumor. Allelic deletion on chromosome 14q plays an essential role in GBM pathogenesis, and this chromosome 14q site was thought to harbor multiple tumor suppressor genes associated with GBM, a region that also encodes microRNA-203 (miR-203). This study was conducted to identify whole transcriptome profile changes associated with miR-203 expression by high-throughput NGS-RNA sequencing. Total RNA samples are quantified using Nanodrop and qualified by agarose gel electrophoresis. The mRNA is enriched by oligo(dT) magnetic beads or the total RNA is depleted of rRNAs by Arraystar rRNA Removal Kit if the RNA sample is degraded or is of prokaryotic origin. We use Illumina kits for the RNA-seq library preparation, which include procedures of RNA fragmentation, random hexamer primed first strand cDNA synthesis, dUTP based second strand cDNA synthesis, end-repairing, A-tailing, adaptor ligation and library PCR amplification. Finally, the prepared RNA-seq libraries are qualified using Agilent 2100 Bioanalyzer and quantified by qPCR absolute quantification method. The sequencing is performed using Illumina Hiseq 4000.

ASC-J9 blocks STAT3 signaling, cell proliferation, collagen synthesis, inflammation, and ROS generation in keloid fibroblasts

Project description:The purified RNA from NFs (n=1) and KFs (n=1) treated with DMSO or ASC-J9 was used for the preparation of the sequencing library by the TruSeq Stranded mRNA Library Prep Kit (Illumina, San Diego, CA, USA) according to the manufacturer’s recommendations. Briefly, mRNA was purified from total RNA (1 µg) by oligo(dT)-coupled magnetic beads and fragmented into small pieces under elevated temperature. The first-strand cDNA was synthesized using reverse transcriptase and random primers. After the generation of double-strand cDNA and adenylation on the 3’ ends of DNA fragments, the adaptors were ligated and purified with the AMPure XP system (Beckman Coulter, Beverly, USA). The quality of the libraries was assessed by the Agilent Bioanalyzer 2100 system and a real-time PCR system. The qualified libraries were then sequenced on an Illumina NovaSeq 6000 platform with 150-bp paired-end reads generated by Genomics BioSci & Tech Co., Ltd.

RNA sequencing of bone marrow macrophages from non-Hodgkin lymphoma Raji cell engrafted mice

Project description:Purpose: The study aimed to characterize the molecular phenotype of bone marrow macrophages in NHL with RNA sequencing analysis. Methods:RNA of sorted femur macrophages (CD11b+F4/80+) were extracted with an RNA extraction kit (Qiagen). The samples were submitted to Novogene Inc. for library preparation and subsequent RNA sequencing. RNA was used for cDNA library construction using an NEBNext® Ultra RNA Library Prep Kit for Illumina® (New England Biolabs) according to the manufacturer’s protocol. The resulting 250-350 bp insert libraries were quantified using a Qubit 2.0 fluorometer (Thermo Fisher Scientific) and quantitative PCR. Size distribution was analyzed using an Agilent 2100 Bioanalyzer (Agilent Technologies). Qualified libraries were sequenced on an Illumina HiSeq 4000 Platform (Illumina) using a paired-end 150 run (2×150 bases). Reads containing adapter or poly-N and those of low quality were trimmed, after which gene counts were obtained though mapping the clean reads to reference genome mm10 using STAR 2.5.3a.

Project description:Whole MeRIP-sequencing analysis was performed and analyzed by Lc. Aksomics Co. Ltd. (Shanghai, China). The peri-infarct cortex from sham mice, PT mice with EV-Vector, and PT mice with EV-circSCMH1 was collected in TRIzol. Total RNAs were qualified by agarose gel electrophoresis and quantified using Nanodrop. mRNA was isolated and then fragmented to 100-nucleotide-long fragments. m6A methylated mRNAs were enriched with anti-N6-methyadenosine(m6A) antibody. We use commercial kit for RNA-seq library prepa ration of m6A mRNA and input samples. Completed libraries were qualified and then sequenced on Hiseq 4000 platform.

TP53 and TP63 modulation of Squamous PDAC

Project description:Based on the association of TP53 mutation and upregulated TP63 expression in the squamous subtype, we used cell lines derived from genetically engineered mouse models of PDAC (KRAS Trp53fl/+ and KRAS Trp53fl/+ Trp63fl/fl) to begin to unravel the functional consequences of these events in defining squamous tumours. RNA-Seq libraries were generated using TruSeq Stranded Total RNA (Part no. 15031048 Rev. D April 2013) kits, using on a Perkin ElmeraTMs Sciclone G3 NGS Workstation (Product no. SG3-31020-0300). Ribosomal depletion step was performed on 1 ug of total RNA using Ribo-Zero Gold prior to a heat fragmentation step aimed at producing libraries with an insert size between 120-200 bp. cDNA was then synthesized from the enriched and fragmented RNA using InvitrogenaTMs SuperScript II Reverse Transcriptase (Catalog no. 18064) and random primers. The resulting cDNA was further converted into double stranded DNA in the presence of dUTP to prevent subsequent amplification of the second strand and thus maintain the strandedness of the library. Following 3aTM adenylation and adaptor ligation libraries were subjected to 15 cycles of PCR to produce RNA-Seq libraries ready for sequencing. Prior to sequencing, exome and RNA-Seq libraries were qualified and quantified via CaliperaTMs LabChip GX (Part no. 122000) instrument using the DNA High Sensitivity Reagent kit (Product no. CLS760672). Quantification of libraries for clustering was performed using the KAPA Library Quantification Kits For Illumina sequencing platforms (Kit code KK4824) in combination with Life Technologies Viia 7 real time PCR instrument. All libraries were sequenced using the Illumina HiSeq 2000/2500 system with TruSeq SBS Kit v3 - HS.

RNA-seq of primary mouse podocytes with KDM6A overexpression against controls

Project description:We performed RNA-seq experiments (three replicates) on primary mouse podocytes that were infected with control lentivirus or KDM6A-encoding lentiviruses. RNAs were first extracted using Trizol reagent (Invitrogen, USA) according to the manufacturer’s instruction. The purified RNAs were quantified at OD260nm using a ND-1000 spectrophotometer (Nanodrop Technology, USA) and qualified using a Bioanalyzer 2100 (Agilent Technology, USA) with RNA 6000 LabChip kit (Agilent Technology, USA). All procedures for library preparation and sequencing were performed according to the Illumina protocol. Library construction was carried out using the TruSeq RNA Library Preparation Kit for 75 bp Single-End sequencing on Solexa platform. The sequence was directly determined by sequencing-by-synthesis technology via the TruSeq SBS kit (Illumina Inc., USA). Raw sequences were obtained from the Illumina Pipeline software bcl2fastq v2.0, which was expected to generate 30 million reads per sample. Qualified reads after filtering low-quality data were analyzed using TopHat/Cufflink. Quantification for gene expression was calculated as fragments per kilobase of transcript per million mapped reads (FPKM).

Effect of miR-203 on the transcriptomic profile of IPSCs and IPSC-derived teratomas

Project description:The balance between pluripotency and differentiation is critical during development and regeneration. miR-203 is a microRNA previously involved in differentiation of different tissues as well as in tumor suppression in multiple malignancies. We have shown that miR-203 is able to promote differentiation of embryonic stem (ES) and induced pluripotent stem (iPS) cells without decreasing pluripotency. We have observed that transient expression of miR-203 significantly improves the efficiency of ES/iPS cells in the generation of quimeras and tetraploid complementation assays, in addition to inducing complex embryo-like structures when these pluripotent cells are injected in mice. In the present RNA seq, we intend to analyze the trascriptomic profile of WT IPSCs, compared to miR-203 KO IPSCs and miR-203 tKI IPSCs (in which we have induced a transient over-expression of miR-203). Moreover, we analyze the mRNA profiles of the teratomas derived from those IPSCs.
