  • Transcription Factor Binding Sites, Motifs and Profiles from ChIP-seq data

    ChIPBase v2.0 is designed for studying transcription factor binding sites and motifs, and decoding transcriptional regulatory networks of non-coding RNAs (lncRNAs, miRNAs, snoRNAs, tRNAs...) and protein-coding genes (PCGs) from ~10,200 ChIP-seq data (ChIP-seq, ChIP-exo, MNChIP-seq) in 10 speices (Human, Mouse, Fruitfly, Worm, A. Thaliana, Yeast, Rat, Zebrafish, X. tropicalis, Chicken).

    We identified thousands of Binding Motif Matrices and their binding sites from ChIP-seq data of DNA-binding proteins and predicted millions of transcriptional regulatory relationships between transcription factors and genes (lncRNAs, microRNAs, protein-coding genes, snoRNAs, tRNAs).

    We constructed Regulator module to predict hundreds of transcription factors that were involved in or affected transcription of ncRNAs and protein-coding genes.

    Moreover, we built a web-based tool, Co-Expression, to explore the co-expression patterns between DNA-binding proteins and various types of genes by integrating the gene expression profiles of ~10,000 tumor samples and ~9,100 normal tissues or cell lines.

    ChIPBase also provides a ChIP-Function tool and a genome browser to predict functions of diverse genes and visualize various ChIP-seq data. This study will greatly expand our understanding of the transcriptional regulations of ncRNAs and protein-coding genes.

    ChIPBase paper is available at http://nar.oxfordjournals.org/conten...ar.gkw965.full

    ChIPBase is freely available at http://rna.sysu.edu.cn/chipbase/.

    Strategies for Sequencing Challenging Samples
    by seqadmin


    Despite advancements in sequencing platforms and related sample preparation technologies, certain sample types continue to present significant challenges that can compromise sequencing results. Pedro Echave, Senior Manager of the Global Business Segment at Revvity, explained that the success of a sequencing experiment ultimately depends on the amount and integrity of the nucleic acid template (RNA or DNA) obtained from a sample. “The better the quality of the nucleic acid isolated...
