Project description:Beyond the regulation of mRNAs by individual ncRNA types, such as miRNAs or lncRNAs, their interplay as so-called competitive endogenous RNAs (ceRNAs) appears to play a pivotal role in diseases. In our study we aimed to get a holistic understanding of the tRNA 2’O-methyltransferase FTSJ1 and its regulatory role in the context of cognitive disability. Here, we investigated the impact of Ftsj1 deficiency on ceRNA networks across different mouse organs. Our study underscores the critical role of organ-specific ceRNA networks, particularly in metabolic regulation, and emphasizes the need for cross-organ analyses to unravel the complexity of ceRNA-mediated gene regulation. Our findings reveal a prominent ceRNA network in the liver, mediated by four hub miRNAs (miR-378d, miR-3076-5p, miR-3474, and miR-296-3p) and enriched with acetyl CoA-related genes, including Acly, Acss2, and Mvk. These genes are integral to fatty acid metabolism, which is heavily disrupted in both liver and kidney. In contrast, brain tissues exhibited minimal changes, suggesting only a limited impact directly related to Ftsj1 in this organ. These results suggest that the cognitive disability associated with Ftsj1 is driven by metabolic and ceRNA crosstalk along the liver-brain and kidney-brain axes. This dataset comprises the miRNA-seq data used in our study.

Project description:FTSJ1 is a conserved human 2’-O-methyltransferase (Nm-MTase) that modifies several transfer RNAs (tRNAs) at position 32 and the wobble position 34 in the AntiCodon Loop (ACL). Its loss of function has been linked to Non-Syndromic X-Linked Intellectual Disability (NSXLID), and more recently to cancers. However, the molecular mechanisms underlying these pathologies are currently unclear. Here we report a novel FTSJ1 pathogenic variant from a NSXLID patient. Using blood cells derived from this patient and other affected individuals carrying FTSJ1 mutations, we performed an unbiased and comprehensive RiboMethSeq analysis to map the ribose methylation (Nm) on all tRNAs and identify novel targets. In addition, we performed a transcriptome analysis in these cells and found that several genes previously associated with intellectual disability and cancers were deregulated. We also found changes in the miRNA population that suggest potential cross-regulation of some miRNAs with these key mRNA targets. Finally, we show that differentiation of FTSJ1-depleted human neuronal progenitor cells (NPC) into neurons displays long and thin spine neurites compared to control cells. These defects are also observed in Drosophila and are associated with long term memory deficit in this organism. Altogether, our study adds insight into FTSJ1 pathologies in human by the identification of novel FTSJ1 targets and the defect in neuron morphology.

Project description:We analyzed the transcriptomic differences of cultured mouse spermatocytes (GC2 cells) stably transfected with PHB-targeting shRNA (called PHB KD GC2) from those with a control shRNA (called Ctrl GC2). Furthermore, we also analyzed the difference in the transcriptomes of spermatocytes between Phb conditional knock-out and control mice.

Project description:Our previous study identified that a novel tRNA-derived fragment (tRF) termed AS-tDR-007333 was up-regulated in non-small cell lung cancer (NSCLC), but the molecular mechanisms of AS-tDR-007333 in NSCLC were unclear. Here, we used RNA-seq for high-throughput profiling of transcriptomes in A549 cells transfected with AS-tDR-007333, in order to find differentially expressed genes regulated by AS-tDR-007333.
