Project description:Single/double/triple mutants of hat1, hat2, hif2 and histone mutants have been analyzed by expression profiling in high glucose and under starvation
Project description:(1)In vivo SILAC analyses of mouse embryonic fibroblasts (MEFs, triple labeling) were performed comparing phosphorylation events. ULK1 double knock out MEFs (VC) were compared to double knock out MEFs expressing human ULK1 (RE) in fed (DMEM) and starvation (HBSS) conditions. (2) In vivo SILAC analyses of A549 cells (triple labeling) were performed comparing phosphorylation events (195 raw files labeled ""A549""). A549 cells in fed conditions (DMEM) were compared to starved cells (HBSS) and cells treated with rapamycin (Rapa).
Project description:Many microRNAs (miRNAs) exist alongside abundant miRNA isoforms (isomiRs), most of which arise from post-maturation sequence modifications, such as 3’ uridylation and adenylation. However, the ways in which these sequence modifications affect miRNA function remain poorly understood. To this aim, we have generated single knock-out cell lines of TUT4, TUT7 and TENT2 (TUT2), as well as double knock-out (DKO) and triple knock-out (TKO) cell lines. Here, using these different cell lines, we have discovered that some of the redundant functions and specific functions of each tailing enzyme. Our study provides a comprehensive characterization of tailing on miRNAs.
Project description:The yeast PP2A-Cdc55 Serine/Threonine phosphatase regulates transcription under certain conditions. It is required for full activation of the environmental stress response mediated by the transcription factors Msn2 and Msn4. PP2A-Cdc55 contributes to sustained nuclear accumulation of Msn2 and Msn4 and extended chromatin recruitment under stress conditions such as hyperosmolarity stress. Transcript profiles of Msn2 and Msn4 double mutants are similar to cdc55 and the corresponding triple mutants. This argues for a Msn2/4 specific function of PP2A-Cdc55. Time course of 10 20 and 30 minutes hyperosmolarity treated yeast cells of wild type (W303), msn2msn4, cdc55, msn2msn5cdc55 genetic background.
Project description:Contains gene expression profiles of yeast single and double deletion mutants of gene-specific transcription factors. Genetic interactions were studied by comparing gene expression changes of double mutants with gene expression changes in the respective single mutants. Pairs of gene-specific transcription factors were chosen based on previous evidence for epistasis, including synthetic genetic interactions as well as common DNA binding.
Project description:We tested how complete or partial loss of endophilin A1, A2 and A3 affects gene expression in mouse hippocampus. Total loss of endophilin (triple knock-outs, TKO) was assessed in newborn mice, since the TKO mice only survive only several hours after birth. Partial loss of endophilin (endoA1,A2 double knock-out, DKO) was assessed between
Project description:BRD1, BRD2, and BRD13 are likely subunits of Arabidopsis SWI/SNF chromatin remodeling complexes. To investigate the effect of disruption of BRD genes on global gene expression in Arabidopsis, we performed transcriptome profiling of 18-day-old single brd2, double brd1 brd2 and triple brdx3 mutants.
