Genome-wide maps of QKI-5, SREBP2, and POL II in eye lens cells

ABSTRACT: We found the genome-wide co-binding of QKI-5 and SREBP2. Notably, the genomic distribution analysis revealed that the co-binding events between QKI-5 and SREBP2 highly occurred at the regions of the promoter/transcription start site (TSS), where active transcription was taken place in a lens cell-specific manner, which was indicated by POL II binding events. Cellular pathway analysis of the genes whose promoters were co-bound by QKI-5, SREBP2, and POL II showed a significant enrichment of the SREBP2-medaited cholesterol biosynthesis pathway, and QKI depletion led to reduced co-occupancies of SREBP2 and POL II on the promoters of the genes involved in cholesterol biosynthesis. These data suggest QKI-5 as a potential transcription co-activator mediating SREBP2-dependent cholesterol biosynthesis in eye lens cells.

Genome-wide maps of Qki-5, Srebp2, and Pol II in oligodendrocytes

Project description:We found the genome-wide co-localization of Qki-5 and Srebp2. Notably, the genomic distribution analysis revealed that Qki-5 and Srebp2 highly co-occupied the regions of the promoter/transcription start site (TSS), where active transcription was taken place in a oligodendrocyte-specific manner, which was indicated by Pol II binding events. GO analysis of the genes whose promoters were co-bound by Qki-5, Srebp2, and Pol II showed a significant enrichment of the Srebp2-mediated cholesterol biosynthesis pathway, and Qki depletion led to reduced recruitment of Srebp2 and Pol II on the promoters of the genes involved in cholesterol biosynthesis. These data suggest Qki-5 as a potential transcription co-activator of Srebp2-mediated cholesterol biosynthesis in oligodendrocytes.

Genome-wide maps of Qki-5 and PPARb in mouse oligodendrocytes

Project description:We found that there is a big overlap between the Qki5- and PPARb-binding events by ChIP-seq. Interestingly, the genomic distribution analyses of Qki-5- and PPARβ-binding events showed significant enrichment at the regions of the promoter/transcription start site (TSS) which were indicated by Pol II-binding events. The strong preference of the promoter/TSS co-occupancy suggested that Qki-5 might play an important role in PPARβ-mediated transcriptional regulation of its downstream genes.

The mechanistic studies of GATA1 regulation of SREBP2 in G1-ER4 cells

Project description:In our work, we uncovered a critical role for cholesterol homeostasis in terminal erythropoiesis. The master transcriptional factor GATA1 binds to Sterol-regulatory element binding protein 2 (SREBP2) to downregulate cholesterol biosynthesis, leading to a gradual reduction in intracellular cholesterol levels. To reveal genetic interactions and epistatic relations between GATA1 and SREBP2 on depth at the whole genome level, we performed RNA sequencing to analyze the gene expression profiles change between treated with Vehicle or β-estradiol in overexpressing active SREBP2 G1E-ER4 cells.

Analysis of gene expression in QKI knockdown CG-4 cells

Project description:QKI is required for myelin formation in the verterbrate brain. It functions by binding RNA and regulating its stability, translation, and/or aternative splicing. We have used Affymetrix exon arrays to assess changes in gene expression in response to QKI knockdown on an exon level in rat CG-4 oligodendrocyte precursor cells. Knockdown cells were compared to control cells. Knockdown groups included QKI siRNA transfection, QKI shRNA stable transfection, and hnRNP A1 transient transfection. Control groups consisted of untransfected, control siRNA transfection, control shRNA stable transfection. Each group was analyzed in triplicate.
