RNA-seq transcriptome profiling of young gametophytes and capsules at different developmental stages of Pogonatum aloides

ABSTRACT: To investigate global gene expression during development in Pogonatum aloides, digital gene-expression profiling of capsules at different developmental stages was performed by Illumina HiSeq™ 2000 sequencing platforms, with the young gametophyte being used as a control. The samples of P. aloides were collected from Jiming Mountain, Ningde (26°56'39.34"N; 118°57'21.45"E, and stored in RNAlater solution. Total RNAs were extracted using the TRIzol reagent. The RNA-Seq reads were assembled into transcripts using SOAPdenovo v1.04. Gene expression levels were calculated from the number of uniquely aligned clean reads and then normalized into units of Reads Per Kilobase per Million reads mapped (RPKM). Genes were considered to be differentially expressed if they had an FDR < 0.05, P-value < 0.05, and the absolute value of log2Ratio ≥ 1 between reproductive and vegetative samples. As a result, 4007 genes were found to be up-regulated in reproductive/meiotic samples.

RNA-Sequencing analysis of reproduction/meiosis in Selaginella moellendorffii

Project description:To investigate global gene expression during meiosis in S. moellendorfii, digital gene-expression profiling of a series of sporangia at different developmental stages was performed by Illumina HiSeq™ 2000 sequencing platforms, with young leaves being used as a control. The samples were collected from South Mountain, Chongqing (29°33'44.18"N; 106°37'35.62"E) and stored in RNAlater solution. Total RNAs were extracted using the TRIzol solution. The clean reads were aligned to the genome sequence of S. moellendorfii at JGI database by SOAP2. Gene expression levels were calculated from the number of uniquely aligned clean reads and then normalized into units of Reads Per Kilobase per Million reads mapped (RPKM). Genes were considered to be differentially expressed if they had an FDR < 0.05, P-value < 0.05, and the absolute value of log2Ratio ≥ 1 between reproductive and vegetative samples. As a result, 5416 genes were found to be up-regulated in reproductive/meiotic samples.

Next generation sequencing of the transcriptome in MCF-7 cells with/without SRA knockdown

Project description:We employed next generation sequencing to examine whether knocking down the steroid receptor RNA activator (SRA) gene significantly affect the expression levels of certain genes in MCF-7 cells. MCF-7 cells were transfected with either a pool of four non-target control siRNAs or a pool of four SRA siRNAs for 32 hrs. 157 million reads were generated from triplicate samples of the control group; 151 million reads were generated from triplicate samples of the SRA knockdown group. Six genes were identified as significantly changed in the expression levels with the cutoff of q value ≤ 0.05, fold change ≤ 0.5 or ≥ 2, and reads per kilobase per million mapped reads (RPKM) ≥ 1. However, except for SRA itself, the other five genes were shown by real-time PCR to be only affected by one siRNA in the SRA siRNA pool. Further analysis of this dataset with different cuttoff setting may reveal true SRA-regulated genes in MCF-7.

Next-generation sequencing analyses of the differently expressed genes of wild type and atcep1 mutant Arabidopsis thaliana

Project description:Purpose: The goal of this study is to compare the differently expressed genes in the wild type and the KDEL-tailed cysteine protease AtCEP1 knockout (atcep1) Arabidopsis using RNA-sequencing (RNA-seq). Methods: Arabidopsis buds mRNA profiles of anther development stages 5-6, 7-9, and 10-11 of the wild type (WT) and atcep1 mutant were generated by deep sequencing via Illumina HiSeqTM 2000. The sequence reads that passed quality filters were analyzed at the transcript isoform level with the following steps: Remove reads with adaptor sequences; Remove reads in which the percentage of unknown bases (N) is greater than 10%; Remove low quality reads, in which the percentage of the low quality base (base with quality value ≤ 5) is greater than 50%. The clean reads were mapped to the Arabidopsis reference genome and reference genes using SOAP aligner/SOAP2. No more than 2 mismatches were allowed in the alignment. The gene expression level was calculated using RPKM (Reads Per Kb per Million reads). Differential expression analysis between the wild type and the atcep1 mutant was performed using the DEGseq R package (1.12.0) based on normalized read counts. A corrected P value of < 0.005 and |log2Ratio| > 1 were set as the threshold for significantly differential expression. Results: We identified 872 genes showing significant differential expression, and in the atcep1 mutant, the upregulated genes significantly outnumbered the downregulated genes at the three time points. The GO analysis of the differently expressed genes showed that the expression of genes participating in anther tapetal secretory structure formation, pollen wall development, and tapetal cell wall generation, clearly changed.

Results: Using an optimized data analysis workflow, we mapped about 68-91 million sequence reads per sample to the chicken spleens from the infection and control group by Hisat2. Approximately a quarter of the transcripts showed differential expression between the infection and control group, with a 5x SD fold change and p value <0.05.

Gene expression profiling of human angiosarcoma

Project description:We generated RNA-Seq data from human angiosarcoma tissues (N=13) and non-malignant tissue samples (N=6). The goal of this study was to determine differentially expressed genes in the tumors compared to controls. We sequenced about 80 – 100 million sequence reads per sample and mapped to the human reference genome (GRCh38). We identified 1,237 differentially expressed genes between the tumors and non-malignant controls (FDR P-value < 0.05): 490 genes were upregulated and 747 genes were downregulated in angiosarcomas. Our results show a comprehensive data of fusion genes and gene expression profile in human angiosarcomas using RNA-seq technology.
