Ribosome profiling in transgenic and HEK293T cells treated with NAEK

ABSTRACT: To investigate whether natural TAG was decoded by stably transfected Mb pyltRNA in transgenic cells, their cell lysate was subjected to ribosome profiling, examining the physical locations of ribosomes. HEK293T cells were taken as control.

Ribosome profiling in transgenic and HEK293T cells

Project description:To investigate whether natural TAG can be decoded by stably transfected pyltRNA, whole cell lysate of transgenic cells was collected 48h after the addition of NAEK and subjected to ribosome profiling, examining the physical locations of ribosomes along 15662 TAG terminated transcripts. And HEK293T cells were taken as control.

Ribo-seq of HEK293T overexpressing WT and G240R GARS

Project description:Charcot-Marie-Tooth (CMT) disease can be caused by mutations in Aminoacyl-tRNA-Synthetases, including G240R mutation in Glycyl-tRNA-Synthetase (GARS). Ribo-seq generates snapshots of translating ribosomes on mRNA and therefore allows analysis of ribosome pausing mRNA. Here we performed Ribo-seq on lysates of HEK293T cells overexpressing GARS, WT or G240R, to dissect mechanism of CMT linked with translation. We found that GARS G240R causes pausing of ribosomes with glycine codons in A-site. The effect is specific for 21 nt ribosome-protected fragments, produced by ribosomes with empty A-sites, suggestive of the deficit of charged Glycyl-tRNA in GARS G240R-CMT.

Active ribosome profiling with RiboLace and standard ribosome profiling in HEK-293 cells

Project description:We developed RiboLace, a novel method based on a new puromycin-containing molecule, for the isolation of active ribosomes by means of an antibody-free and tag-free pull-down approach. RiboLace is fast, it works with very low input material and can be easily and rapidly used to enhance Ribo-Seq, obtaining a global snapshot on active ribosome footprints at single nucleotide resolution from eukaryotic in vitro and in vivo systems. Keywords: ribosome profiling, translation, RiboLace, Ribo-Seq, active translation

mRNAs associated with Ago2: Ago2, Ago2+miR-1, Ago2+miR-124, mock transfected

Project description:As a core RISC component, Ago2 associates with miRNAs and target mRNAs. To identify these mRNAs, we ran lysate from HEK293T cells over a FLAG resin from 2 conditions: +FLAG-Ago2, +mock transfection. To identify mRNAs associated with specific miRNAs, we ran lysate from HEK293T cells over a FLAG resin from 2 conditions: +FLAG-Ago2 & miR-1, and +FLAG-Ago2 & miR-124. Set of arrays that are part of repeated experiments Compound Based Treatment: mock transfected Keywords: Biological Replicate

Analysis of the genomic composition of phage YerA41

Project description:Genomic material isolated from purified phage YerA41 lysate was shown to contain RNA. YerA41 phage lysate was RNase treated to remove phage-external RNA and total RNA was then isolated from the phage preparate using Qiagen Rneasy mini kit. The isolated RNA was sequenced to elucidate its origin. The results suggested that the RNA originated from intact ribosomes of the host bacterium that contaminated the phage lysate.
