Genetic interaction analysis of RSA1 deletion strains (GIM screen)

ABSTRACT: A S. cerevisiae strain with deletion of RSA1 gene was combined with two collections of yeast mutants: one in which non-essential genes were deleted and one in which an long 3' UTR extension has been added to the mRNA of essential genes (GIM method, Decourty et al., 2008). Combined double-mutant deletion cells growth was quantified using barcodes that are specific for each gene mutation. A reference population was obtained by mixing the results of 15 GIM screens DNA prior to barcode amplification and labeling (Decourty et al., in preparation). The identification of genetic interactions between deletion of RSA1 and deletion of RTT106, a histone chaperone, indicate a potential role of Rtt106 in snoRNP formation.

Genetic interaction mapping (GIM) for factors involved in RNA and protein synthesis and degradation

Project description:A S. cerevisiae strain a gene of interest mutated or deleted was combined with two collections of yeast mutants: one in which non-essential genes were deleted and one in which an long 3' UTR extension has been added to the mRNA of essential genes (GIM method, Decourty et al., 2008). Combined double-mutant deletion cells growth was quantified using barcodes that are specific for each gene mutation. A reference population was obtained by mixing the results of 15 GIM screens DNA prior to barcode amplification and labeling (Decourty et al., in preparation). The identification of genetic interactions between genes involved in different cellular pathways indicate new functions for previously characterized genes and new links between

Transcriptome profiling reveals a novel role for Trichostatin A in antagonizing histone chaperone Chz1 mediated telomere anti-silencing.

Project description:The histone chaperones play an important role in chromatin assembly and disassembly during replication and transcription. We assessed the global roles of histone chaperones in Saccharomyces cerevisiae. Microarray transcriptional analyses indicate that histone chaperones have their own specific target genes, and various histone chaperones have partially overlapping functions during transcriptional regulation. Histone deacetylase inhibitor TSA and histone chaperones Asf1, Vps75 and Rtt106 can function in parallel pathways to regulate transcription. Moreover, TSA can specifically antagonize histone chaperone Chz1-mediated telomere anti-silencing. This study demonstrates that a mutual cross-talk mechanism exists between histone chaperones and histone deacetylation in transcriptional regulation. All yeast strains used in this study are listed in the paper (Table S1). CHZ1, NAP1, ASF1, VPS75 and RTT106 genes were deleted individually by homologous recombination in BY4742 (WT) by using a previously described in (Wan, Y. et al. MCB, 2009) PCR-based procedure. The strains were cultured at 30°C in YPD (1% yeast extract, 2% peptone, 2% glucose) media. For TSA treatments, WT and deletion mutants were grown to mid-log phase (OD600=0.5), TSA (Sigma-Aldrich) was then added to the yeast cultures at a final concentration of 10 ?M and cells were cultured for additional hour.Total RNA was isolated by hot acid phenol extraction protocol as previously described in Wan, Y. et al. MCB, 2009. Microarray labeling and hybridization reactions were performed as previously described in Wan, Y. et al. MCB, 2009 and Wan, Y. et al. NAR, 2010. Two color microarrays, comparing RNA from the experimental conditions (deletion mutations grown in YPD, WT and deletion mutations grown in YPD with TSA treatment) to RNA from the control WT cells grown in glucose-containing medium (YPD), were performed using Agilent whole-genome S. cerevisiae arrays.

Strain abundance assay of barcoded DAmP loss of function S. cerevisiae strains exposed to various compounds

Project description:The ability to perform complex bioassays in parallel enables experiments otherwise impossible due to throughput and cost constraints. By way of example, highly parallel chemical-genetic screens using pooled collections of thousands of defined Saccharomyces cerevisiae gene deletion strains are feasible because each strain is barcoded with unique DNA sequences. It is, however, time consuming and expensive to individually barcode individual strains. To provide a simple and general method of barcoding yeast collections, we built a set of donor strains, called Barcoders, with unique barcodes that can be systematically transferred to any S. cerevisiae collection. We applied this technology by generating a collection of barcoded DAmP (Decreased Abundance by mRNA Perturbation) loss-of-function strains comprising 87.1% of all essential yeast genes. This test collection validates both the Barcoders and the DAmP collection as useful tools for genome-wide chemical genetic assays.

Mouse Smartseq3 Data from Mold et al. Clonally Heritable Gene Expression Imparts a Layer of Diversity in Cell Types

Project description:Mouse cells harvested from the central nervous system of two different mice injected at post-coital day 9.5 with lentivirus encoding barcodes that allow for clonal tracking and gene expression in single cell RNAseq measurements (TREX, Ratz et al 2022). Cells are isolated from the cortex 14 days after birth and profiled by scRNA-seq using the Smartseq3 method.
