RNA-seq on ES cells where DDX6 was knocked down by the AID method

Project description:To degrade DDX6 acutely, we adopted an advanced protein degradation method, the auxin-induced degron (AID) system. For this purpose, we prepared an AID-tagged DDX6 and E3 ligase subunit of OsTIR1 in an engineered ES (D6AdP cell line). These deposited data are RNA-seq data on these D6AdP ES cells treated with the auxin analog (IAA) treatment for 0, 3, and 6 hours.

TJ1081)fer-15(b26)II; daf-16(m26)I) vs. BA713(fer-15(b26)II)

Project description:To identify changes in gene expression in daf-16 mutants, we compared expression in fer-15 young adults to expression in fer-15(b26); daf-16(m26) young adults grown at 25?C. At Stanford University, four samples of fer-15 and five samples of fer-15; daf-16 animals were prepared. At the University of Colorado, seven samples of fer-15 and six samples of fer-15; daf-16 was prepared. Set of arrays that are part of repeated experiments Place of growth: At Stanford vs Colorado Genotype: mutant strains vs wt (N2) mixed stage; some expts are reverse dye (wt in channel 2)

Project description:Transcriptional profiling of adult C. elegans comparing daf-16(-); daf-2(-) animals with adult daf-2(-) animals. Two-condition experiment, daf-2 mutants treated with daf-16 RNAi vs. daf-2 mutants treated with empty vector RNAi. Biological replicates: 8 daf-2 mutants treated with daf-16 RNAi vs. daf-2 mutants treated with empty vector RNAi, independently grown and harvested. One replicate per array.

RNA-seq analysis of young adult daf-18(ok480) and control worms

Project description:RNA-seq analysis was used to identify the gene expression changes in male and hermaphroditie when daf-18 is lost. Based on these sequencing data, the genes that were up-regulated or down-regulated by at least 2 times (|log2 (folding change) | ≥ 1 and padj ≤ 0.05) were analyzed. The analysis of these differentially expressed genes' pathway and gene ontology (GO) enrichment shows that the influence of different genders after daf-18 deletion is enriched to some signal pathways, including longevity and protein degradation pathway in endoplasmic reticulum, etc.

DAF-16/FoxO and EGL-27/GATA promote developmental growth in response to persistent somatic DNA damage [N2, daf-2, daf-16, daf-2;daf-16]

Project description:Genome maintenance defects cause complex disease phenotypes characterized by developmental failure, cancer susceptibility and premature aging. It remains poorly understood how DNA damage responses function during organismal development and maintain tissue functionality when DNA damage accumulates with aging. Here we show that the FoxO transcription factor DAF-16 is activated in response to DNA damage during development while the DNA damage responsiveness of DAF-16 declines with aging. We find that in contrast to its established role in mediating starvation arrest, DAF-16 alleviates DNA damage induced developmental arrest and even in the absence of DNA repair promotes developmental growth and enhances somatic tissue functionality. We demonstrate that the GATA transcription factor EGL-27 co-regulates DAF-16 target genes in response to DNA damage and together with DAF-16 promotes developmental growth. We propose that EGL-27/GATA activity specifies DAF-16 mediated DNA damage responses to enable developmental progression and to prolong tissue functioning when DNA damage persists. Synchronized L1 and mutant larvae were UV or mock treated, or starved. Mock treated samples served as controls for both the UV-treated and starved groups.

RNA-seq of C. elegans worms treated with RNAi toward daf-2 or cav-1 or left untreated (EV) to compare gene expression profiles

Project description:We observed functional outcomes of cav-1 knockdown and wanted to characterize changes in gene expression profiles following this manipulation. To address this, we treated nematodes with daf-2 or cav-1 RNAi and compared gene expression profiles to these of untreated worms. The knockdown of cav-1 resulted in modulation in the expression of 92 genes, and some of them overlapped with genes which were affected by knockdown of daf-2.
