Genome-wide nucleosome occupancy profiling by high throughput sequencing, and microarray analysis of RNA abundance


ABSTRACT: We profiled nucleosome occupancy of different developmental stages in C. elegans. Mononucleosomal DNA was sequenced by Illumina paired-end sequencing. We used embryos, germlineless adults, germ line containing adults, and XO hermaphrodites at L3 larval stage. RNA abundance is determined by microarray analysis. We also digested naked DNA with MNase. For data usage terms and conditions, please refer to http://www.genome.gov/27528022 and http://www.genome.gov/Pages/Research/ENCODE/ENCODEDataReleasePolicyFinal2008.pdf After MNase digestion of chromatin, we purified mononucleosomal DNA and used Illumina paired-end sequencing. Mapping was done in embryo (strain N2), germlineless adults (strain JK1107), germ line containing adults (strain DH245),and XO hermaphrodites (strain TY2205) at L3 larval stage. For each experimental replicate RNA abundance is determined by microarray analysis. We also digested naked DNA with MNase.

Many animal species use a chromosome-based mechanism of sex determination, which has led to the coordinate evolution of dosage-compensation systems. Dosage compensation not only corrects the imbalance in the number of X chromosomes between the sexes but also is hypothesized to correct dosage imbalance within cells that is due to monoallelic X-linked expression and biallelic autosomal expression, by upregulating X-linked genes twofold (termed 'Ohno's hypothesis'). Although this hypothesis is well  ...[more]
