Project description: Ribosome profiling (RiboSeq) has emerged as a powerful technique for studying the genome-wide regulation of translation in various cells. Several steps in the biological protocol have been improved, but the bioinformatics part of RiboSeq suffers from a lack of standardization, preventing the straightforward and complete reproduction of published results. Too many published studies provide insufficient detail about the bioinformatics pipeline used. The broad range of questions that can be asked with RiboSeq makes it difficult to use a single bioinformatics tool. Indeed, many scripts have been published for addressing diverse questions. Here, we propose a unique tool (for use with multiple operating systems, OS) to standardize the general steps that must be performed systematically in RiboSeq analysis, together with the statistical analysis and quality control of the sample. The data generated can then be exploited with more specific tools. We hope that this tool will help to standardize bioinformatics analyses pipelines in the field of translation.

Project description:We show that ribosome collisions, induced by Rptor deletion or aminoacid starvation, causes a ZAK alpha mediated identity switch in intestinal stem cells by activating a more fetal-like stem cell signature. This switch also causes changes in metabolic profiles of the cells, which is heavily regulated by RNA translation efficiency of different group of metabolic genes. These observations originate from performing in vitro Riboseq and RNAseq in mouse intestinal organoids, and in vivo Riboseq in Lgr5 expressing intestinal stem cells from WT and Rptor.fl/fl mice.

Project description:To identify DDX3X-dependent translation targets in the developing mouse cortex, we used E11.5 cortices from both sexes of wildtype and conditional Ddx3x knockout mice (driven by Emx1-Cre). We performed RNAseq and Riboseq on these samples in parallel.

Project description:<p>Acute Myeloid Leukemia (AML) commonly relapses after initial chemotherapy response. We assessed metabolic adaptations in chemoresistant cells in vivo before overt relapse, identifying altered branched-chain amino acid (BCAA) levels in patient-derived xenografts (PDX) and immunophenotypically identified leukemia stem cells from AML patients. Notably, this was associated with increased BCAA transporter expression with low BCAA catabolism. Restricting of BCAAs further reduced chemoresistant AML cells but relapse still occurred. Among the persisting cells we found an unexpected increase in protein production. This was accompanied by elevated translation of 2-oxoglutarate-and-iron-dependent oxygenase 1 (OGFOD1), a known ribosomal dioxygenase that adjusts the fidelity of tRNA anticodon pairing with coding mRNA1–3 and upregulates protein synthesis in AML driving disease aggressiveness. Inhibiting OGFOD1 impaired translation processing, decreased protein synthesis and improved animal survival even with chemoresistant AML through regulation of protein synthesis. Leukemic cells can therefore persist despite the stress of chemotherapy and nutrient deprivation through adaptive control of translation while sparing normal hematopoiesis. Targeting OGFOD1 may offer a distinctive, translation modifying means of reducing the chemopersisting cells that drive relapse.</p>
