Project description:Gene-expression noise can influence cell-fate choices across pathology and physiology. However, a crucial question persists: do regulatory proteins or pathways exist that control noise independently of mean expression levels? Our integrative approach, combining single-cell RNA sequencing with proteomics and regulator enrichment analysis, reveals 32 putative noise regulators. The approach utilizes global translation inhibition (i.e., potential protein regulators), and single-cell RNA sequencing (scRNA-seq) to quantify the changes in noise of all transcripts (i.e., potential mRNA targets). This dataset corresponds to the aforementioned scRNA-seq experiment upon translation inhibition with cycloheximide.
Project description:To investigate the role of translation in the decay of cytoplasmic lncRNAs, we performed RNA-Seq in WT and upf1-delta yeast cells, treated or not with CHX.

The approach utilizes global translation inhibition (i.e., potential protein regulators), and single-cell RNA sequencing (scRNA-seq) to quantify the changes in noise of all transcripts (i.e., potential mRNA targets). This dataset corresponds to a control bulk RNAseq experiment experiment upon translation inhibition with cycloheximide to validate the changes in mean observed with single-cell.

Project description:CHX is an inhibitor of translation elongation often used in ribosome profiling experiments. There is evidence that CHX treatment of cells may cause artefacts in the distribution of ribosomes on mRNAs. We investigate this possibility in S. pombe by performing ribosome profiling in the presence and absence of this drug.
Project description:To analyze the effect of global translation initiation inhibition associated to glucose deprivation on cytoplasmic lncRNAs levels, we performed RNA-Seq using WT, xrn1-delta and upf1-delta cells grown in glucose-containing complete synthetic medium (CSM) and then shifted for 16 min in glycerol- and ethanol-containing medium. In parallel, control cells were maintained for the same time in glucose-containing CSM. For the WT strains, we also included a treatment of 15 min with CHX (100 μg/ml final concentration) or an equal volume of DMSO (Mock).
