RNAseq of ribosomal fractionation to assess the effect of CBFB on translation regulation

Project description:Five million wild type (WT) and CBFB knockout (CBFB_KO) MCF10A cells were subject to ribosomal fractination. Total RNA from each fraction was extracted using Trizol followed by Qiagen RNAeasy kit. Polyribosomal fractions were polled as one sample. RNAs in the free, mono- (mono) and polyribosomal (poly) fractions were used for RNAseq.

Cbfb/Runx1-repression independent blockage of differentiation and accumulation of Csf2rb expressing cells by Cbfb-MYH11

Project description:It is known that CBFB-MYH11, the fusion gene generated by inversion of chromosome 16 in human acute myeloid leukemia, is causative for oncogenic transformation. However, the mechanism by which CBFB-MYH11 initiates leukemogenesis is not clear. Previously published reports showed that CBFB-MYH11 dominantly inhibits RUNX1 and CBFB, and such inhibition has been suggested as the mechanism for leukemogenesis. However, knockin mice expressing Cbfb-MYH11 (Cbfb+/MYH11) showed defects in primitive hematopoiesis not seen in Cbfb null (Cbfb-/-) embryos indicating that Cbfb-MYH11 has repression independent activities as well. To identify gene expression changes associated with this novel activity, we compared the gene expression profile in the blood cells of Cbfb+/MYH11 and Cbfb-/- embryonic day 12.5 (E12.5) embryos with that of their wildtype littermates. Cbfb-MYH11 chimeras were mated to C57/Bl6 females to generate Cbfb+/MYH11 (Cbfb+/MYH11) and Cbfb+/+ (WT) embryos. Cbfb+/- x Cbfb+/- matings were used to generate Cbfb+/+ (Cbfb+/+) and Cbfb-/- (Cbfb-/-) embryos. Blood from 8-10 E12.5 embryos of the same genotype was pooled, and RNA was isolated, labeled, and hybridized to Affymetrix Genechip mouse microarray (430 2.0) chips. 4 chips were used for both the Cbfb+/MYH11 and littermate control samples. 3 chips were used for the Cbfb-/- samples and littermate control samples.

p26 condensates from Pea enation mosaic virus 2 sequester ribosomal components and suppress translation

Project description:The p26 movement protein of Pea enation mosaic virus 2 (PEMV2) interacts with the 2'-O-methyltransferase fibrillarin within nuclear and cytoplasmic condensates. This study analyzed global 2'-O-methylation patterns in PEMV2-infected Nicotiana benthamiana using RiboMethSeq, focusing on ribosomal RNAs (rRNAs). The aim was to assess whether PEMV2 disrupts rRNA 2'-O-methylation to interfere with host translation or ribosome assembly.

Duplicated ribosomal protein paralogs promote alternative translation and drug resistance

Project description:Ribosomes are often seen as monolithic machines produced from uniformly regulated genes. However, in yeast most ribosomal proteins come from duplicated genes. Here, we demonstrate that gene duplication may serve as an adaption mechanism modulating the global proteome through the differential expression of ribosomal proteins paralogs after exposure to stress. Our data indicate that the yeast paralog pair of the ribosomal protein L7/uL30 produces two differentially acetylated proteins. Under normal conditions most ribosomes incorporate the hypo-acetylated major form favoring the translation of genes with short open reading frames. Exposure to drugs, on the other hand, increases the production of ribosomes carrying the hyper-acetylated minor paralog that increases translation of long reading frames. Many of these long genes encode cell wall proteins that increase drug resistance in a programed change in translation equilibrium. Together the data reveal a mechanism of translation control through the differential fates of near-identical ribosomal protein isoforms.

Extensive translation of small Open Reading Frames revealed by Poly-Ribo-Seq

Project description:We present a genome-wide assessment of small open reading frames (smORF) translation by ribosomal profiling of polysomal fractions in Drosophila S2 cell. In this way, mRNAs bound by multiple ribosomes and hence actively translated can be isolated and distinguished from mRNAs bound by sporadic, putatively non-productive single ribosomes or ribosomal subunits.

Ribosomal deficiencies in Diamond-Blackfan anemia impair translation of transcripts essential for differentiation of murine and human erythroblasts

Project description:Diamond Blackfan Anemia (DBA) is associated with developmental defects and profound anemia. Mutations in genes encoding a ribosomal protein of the small (e.g. Rps19) or large (e.g. Rpl11) ribosomal subunit are found in over half of these patients. The mutations cause ribosomal haploinsufficiency, which reduces overall translation efficiency of cellular mRNAs. We reduced expression of *Rps19* or *Rpl11* in mouse erythroblasts and investigated mRNA polyribosome association, which revealed deregulated translation initiation of specific transcripts. Among these were *Bag1*, encoding a Hsp70 co-chaperone, and *Csde1*, encoding an RNA binding protein, both expressed at increased levels in erythroblasts. Their translation initiation is cap-independent and starts from an internal ribosomal entry site (IRES), which appeared sensitive to knock down of Rps19 or Rpl11. Mouse embryos lacking Bag1 die at embryonic day E13.5 with reduced erythroid colony forming cells in the fetal liver, and low Bag1 expression impairs erythroid differentiation in vitro. Reduced expression of Csde1 impairs proliferation and differentiation of erythroid blasts. Protein but not mRNA expression of *BAG1* and *CSDE1* was reduced in erythroblasts cultured from DBA patients. Our data suggest that impaired IRES-mediated translation of mRNAs expressed at increased levels in erythroblasts contributes to the erythroid phenotype of DBA. 3 biological replicates of erythroblasts treated with different shRNA were used for polyribosomal sucrose gradients; RNA was extracted from gradients in 2 samples - mRNA associated with polyribosomes (poly) and the rest (sub).
