Project description:Expression profiling following depletion of Mediator Cdk8 module subunits Cdk8, Cyclin C (CycC), Med12 and Med13 72 hours after dsRNA treatment of Drosophila melanogaster S2 cells. Results provide insight into the role of individual Cdk8 module subunits in regulation of transcription.
Project description:We report the application of single-molecule-based sequencing technology (XR-seq) for high-throughput profiling of nucleotide excision repair in Drosophila four developmental stages and S2 cells. By obtaining over six billion bases of sequence from UV and cisplatin damage antibodies immunoprecipitated excision DNA, we generated genome-wide nucleotide excision repair maps of Drosophila Embryo, Larva, Pupa , two gender of adults and S2 cells . We find that Drosophila performs transcription-coupled repair (TCR) at all its developmental stages. S2 cell carry out TCR response to both UV and Cisplatin damage. Finally, we show that XPC repair factor is required for both global and transcription-coupled repair in Drosophila. This study provides the mechanism of nucleotide excision repair of Drosophila in vivo and vitro response to UV and Cisplatin damage.
Project description:H3-ChIP-seq was performed in order to analyze changes in nucleosomal occupancy after depletion of CTCF/P190 and ISWI from Drosophila S2 cells Histone H3 ChIP-seq from Drosophila S2 cells after CTCF/CP190 or ISWI-specific RNAi treatment
Project description:MNase-seq was performed in order to analyze changes in nucleosomal occupancy after depletion of CTCF/P190 and ISWI from Drosophila S2 cells MNase-seq from Drosophila S2 nuclei after CTCF/CP190 or ISWI-specific RNAi treatment
Project description:Profiling of changes in steady state RNA levels upon RNAi-mediated knockdown of the chromosomal kinase JIL-1 in Drosophila S2 cells. Drosophila S2 cells were incubated 7 days after treatment with 10 µg of dsRNA directed against GST/EGFP or JIL-1, respectively. 5 biological replicates per target have been collected.
Project description:Using CRISPR-Cas9 to tag endogenous remodeler subunits in Drosophila melanogaster S2 cells, we demonstrate that developmental gene transcription requires SWI/SNF-type complexes, primarily to maintain distal enhancer accessibility.
Project description:Identification of the interaction partners of the protein ecdysoneless (Ecd) in Drosophila melanogaster S2 cells as well as profiling of the changes in binding for mutant, truncated Ecd del34 protein.
Project description:An Affimetrix GeneChip Drosophila genome 2.0 array was used to study the effect of protocatechuic aldehyde on gene expression. The addition of 0.1 mM protocatechuic aldehyde to Drosophila S2 cells significantly affected the expression of 52 genes, with 29 being up-regulated and 23 being down-regulated.
Project description:We report the application of ultrashort metabolic labeling of RNA for high-throughput profiling of RNA processing in Drosophila S2 cells.
