Project description:The first aim was to identify genes whose transcription is induced by rapamycin feeding in Drosophila S2 cells. Secondly, the goal was to find out which contribution the transcription factors REPTOR (=CG13624) and REPTOR-BP (REPTOR-binding partner, =CG18619) has to the observed changes in expression. We thus compared gene epxression between rapamycin and control treated S2 cells in GFP, REPTOR or REPTOR-BP knockdown cells.
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: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: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 analyzed transcriptional effects after depletion of Drosophila melanogaster S2 cells from CTCF via specific dsRNA treatment in comparison to cells treated with control dsRNA.
Project description:We analyzed transcriptional effects after depletion of Drosophila melanogaster S2 cells from CP190 via specific dsRNA treatment in comparison to cells treated with control dsRNA.
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:V5-TurboID-tagged Drosophila BubR1 and its cleavage variants were transiently expressed in Drosophila S2 cells in two biological replicates. Cells were treated with 500 µM biotin for 30 min for protein biotinylation. Biotinylated protein-containing lysate was subjected to FG-NeutrAvidin beads purification followed by on-beads trypsin digestion. Digested peptides were desalinated and purified using GL-tip SDB. Purified peptides were subjected to LC-MS/MS analysis.
