The tRNA Gm18 Methyltransferase TARBP1 Promotes Hepatocellular Carcinoma Progression via Metabolic Reprogramming of Glutamine [tRNA-seq]

Project description:Cancer cells rely on metabolic reprogramming to sustain the prodigious energetic requirements for rapid growth and proliferation. Glutamine metabolism is frequently dysregulated in cancers and is being exploited as a potential therapeutic target. In current study, we identified TARBP1 (TAR (HIV-1) RNA Binding Protein 1) as a novel driver gene critical for glutamine metabolic reprogramming in tumor through the CRISPRi/Cas9 screening. Our in vivo and in vitro assays demonstrated that TARBP1 is the methyltransferase of Guanosine 2'-O-methylation targeting position 18 (G18) of tRNAGln (TTG/CTG) and tRNASer (TGA/GCT), and loss of Gm18 modification diminishes the stability of tRNAs. Therefore, TARBP1 is critical for maintaining efficient translation of mRNA, in particular the glutamine transportor-ASCT2 (also known as SCL1A5). Importantly, TARBP1 is frequently amplified and overexpressed in HCC, consequentially promotes the protein synthesis of ASCT2 and glutamine import to fuel the growth of cancer cell, which is associated with poor patient survival. Taken together, this study reveals the critical role of TARBP1 in HCC progression through glutamine metabolic reprogramming and provides a potential target for tumor therapy.

Yeast glutamine tRNA synthetase doxycycline shut-off

Project description:During protein synthesis, charged tRNAs deliver amino acids to translating ribosomes, and are then re-charged by tRNA synthetases (aaRS). In humans, mutant aaRS cause a diversity of neurological disorders, but their molecular aetiologies are incompletely characterised. To understand system responses to aaRS depletion, the yeast glutamine aaRS gene (GLN4) was transcriptionally regulated using doxycycline by tet-off control. Depletion of Gln4p inhibited growth, and induced a transcriptional GCN4 amino acid starvation response, indicative of uncharged tRNA accumulation and Gcn2 kinase activation. The GCN4 response was confirmed using SILAC proteomics, using heavy isotope labelling to identify changes in protein expression during glutamine tRNA synthetase depletion.

METTL6 is a tRNA m3C methyltransferase that regulates translation and cell proliferation

Project description:Here, we identified METTL6 as a bona fide tRNA methyltransferase, catalysing the formation of 3-methylcytidine (m3C) at C32 of specific serine tRNA isoacceptors. Accordingly, deletion of METTL6 in mouse stem cells results in changes in ribosome occupancy and RNA levels, as well as a spontaneous loss of pluripotency

Comparison of endogenous tRNA expression levels from cells expressing and sgRNA from either a U6 or tRNA promoter

Project description:The goal of this study was to compare the endogenous tRNA expression levels from cells transduced with a lentiviral vector encopding Cas9 and an sgRNA from a U6 or a Glutamine tRNA promoter. Using high-throughput sequencing methods (Illumina Hi-Seq 2000) we show that endogenous tRNA expression levels are not perturbed by expression of an sgRNA from a human tRNA. tRNA expression profiles were generated from 2 different transduced polyconal cell lines.

Lack of TRMT2A, a tRNA methyltransferase, induces the generation of tRNA-derived small RNAs due to m5U54 tRNA hypomodification [Seq]

Project description:Transfer RNA (tRNA) molecules contain a variety of post-transcriptional modifications which are crucial for tRNA stability, translation efficiency, and fidelity. Besides their canonical roles in translation, tRNAs also originate tRNA-derived small RNAs (tsRNAs), a class of small non-coding RNAs with regulatory functions ranging from translation regulation, to gene expression control and cellular stress response. Recent evidence show that tsRNAs are also modified, however the impact of tRNA epitranscriptome deregulation on tsRNAs generation is only now beginning to be uncovered. The 5-methyluridine (m5U) modification at position 54 of cytosolic tRNAs is one of the most common and conserved tRNA modifications among species. This modification is catalyzed by the tRNA methyltransferase TRMT2A, but its biological role remains largely unexplored. Here, we show that TRMT2A knockdown in human cells induces m5U54 tRNA hypomodification, resulting in angiogenin (ANG) dependent tsRNA formation. More specifically, m5U54 hypomodification is followed by ANG overexpression and tRNA cleavage near the anticodon, resulting in accumulation of 5’tRNA-derived stress-induced RNAs (5’tiRNAs), in particular 5’tiRNA-GlyGCC and 5’tiRNA-GluCTC. Additionally, transcriptomic analysis confirms that down-regulation of TRMT2A and consequently m5U54 hypomodification impacts the cellular stress response and RNA stability, which is often correlated with tsRNA generation. Accordingly, exposure to oxidative stress conditions induces TRMT2A down-regulation and tsRNA formation in mammalian cells. These results establish a link between tRNA demethylation and tsRNAs formation and unravel m5U54 as a tRNA cleavage protective mark.
