Project description:Understanding the molecular mechanisms underlying the regulation of gene expression during skeletal muscle cell proliferation and differentiation is critical to the development of novel therapeutic targets to treat muscle disorders. In this study, we report the identification and characterization of mt-Ty 5’tiRNAs, tRNA-derived fragments (tiRNAs) we identified in skeletal muscle. mt-Ty 5’tiRNAs are found in the nucleus and mitochondria of skeletal muscle cells and its expression is induced by angiogenin. Gapmer-mediated inhibition of tiRNAs in skeletal muscle C2C12 myoblasts resulted in mitochondrial fragmentation. We also observed a decrease in cell proliferation and myogenic differentiation upon mt-Ty 5’tiRNA inhibition; consistent with this observation, RNA-seq and transcriptome analyses revealed that skeletal muscle cell differentiation and cell proliferation pathways were also downregulated. Conversely, overexpression of mt-Ty 5’tiRNAs in C2C12 cells led to a reversal of the transcriptional trends noted for these pathway genes. These data reveal mt-Ty 5’tiRNAs as a skeletal muscle enriched tiRNA that plays important roles in myoblast proliferation and differentiation. Our study also highlights the potential for the development of tiRNAs as novel therapeutic targets for muscle related diseases

Project description:To investigate the effects of NFKB signaling, RNA-seq analysis was performed on both Jurkat and MT-2 cells. It was observed that either NFKB1 or NFKB2 knockout could alter the gene expression profile in MT-2 cells compared to Jurkat cells. Gene expression profiles of NFKB1/NFKB2 knockout Jurkat cells were compared to the mock edited Jurkat cells. On the other hand, it was hypothesized that the gene expression profile of MT-2 cells can be more drastically altered by NFKB1 or NFKB2 knockout. NFKB2 knockout MT-2 cells exhibited a unique gene expression profile compared to those of NFKB1 knockout MT-2 cells and mock edited MT-2 cells.

Project description:Mitochondrial gene expression uses a non-universal genetic code in mammals. Besides reading the conventional AUG codon, mitochondrial (mt-)tRNAMet mediates incorporation of methionine on AUA and AUU codons during translation initiation and on AUA codons during elongation. We show that the RNA methyltransferase NSUN3 localises to mitochondria and interacts with mt-tRNAMet to methylate cytosine 34 (C34) at the wobble position. NSUN3 specifically recognises the anticodon stem loop (ASL) of the tRNA, explaining why a mutation that compromises ASL basepairing leads to disease. We further identify ALKBH1/ABH1 as the dioxygenase responsible for oxidising m5C34 of mt-tRNAMet to generate an f5C34 modification. In vitro codon recognition studies with mitochondrial translation factors reveal preferential utilization of m5C34 mt-tRNAMet in initiation. Depletion of either NSUN3 or ABH1 strongly affects mitochondrial translation in human cells, implying that modifications generated by both enzymes are necessary for mt-tRNAMet function. Together, our data reveal how modifications in mt-tRNAMet are generated by the sequential action of NSUN3 and ABH1, allowing the single mitochondrial tRNAMet to recognise the different codons encoding methionine.
