  • Nearest-neighbor parameters for the prediction of RNA duplex stability in diverse in vitro and cellular-like crowding conditions. Reviewed International journal

     More details

    RNA performs various spatiotemporal functions in living cells. As the solution environments significantly affect the stability of RNA duplexes, a stability prediction of the RNA duplexes in diverse crowded conditions is required to understand and modulate gene expression in heterogeneously crowded intracellular conditions. Herein, we determined the nearest-neighbor (NN) parameters for RNA duplex formation when subjected to crowding conditions with an ionic concentration relevant to that found in cells. Determination of the individual contributions of excluded volume effect and water activity to each of the NN parameters in crowded environments enabled prediction of the thermodynamic parameters and their melting temperatures for plenty of tested RNA duplex formation in vitro and in cell with significant accuracy. The parameters reported herein will help predicting RNA duplex stability in different crowded environments, which will lead to an improved understanding of the stability-function relationship for RNAs in various cellular organelles with different molecular environments.

  • Endogenous G-quadruplex-forming RNAs inhibit the activity of SARS-CoV-2 RNA polymerase. Invited Reviewed International journal

    Replication of RNA viruses is catalysed by virus-specific polymerases, which can be targets of therapeutic strategies. In this study, we used a selection strategy to identify endogenous RNAs from a transcriptome library derived from lung cells that interact with the RNA-dependent RNA polymerase (RdRp) of SARS-CoV-2. Some of the selected RNAs weakened the activity of RdRp by forming G-quadruplexes. These results suggest that certain endogenous RNAs, which potentially form G-quadruplexes, can reduce the replication of viral RNAs.

  • Cladogenetic Orthogonal Light-Up Aptamers for Simultaneous Detection of Multiple Small Molecules in Cells. Reviewed International coauthorship International journal

    Recent successes in construction of light-up RNA aptamers allowed fluorescence-based live-cell imaging of RNAs. In addition, light-up aptamers have been converted into signaling aptamers that enable fluorometric detection of small chemicals. To date, only a single target chemical has been detected at a time in cells. In this study, we selected cladogenetic orthogonal light-up aptamers that output three different colors from the RNA library having the same ligand binding core. Two of the three functioned in mammalian cells. These two aptamers, which fluoresce blue and green upon binding of cognate fluorogen, were converted into signaling aptamers. Using these signaling aptamers in combination with a previously described light-up aptamer with red fluorescence, we demonstrated simultaneous detection of multiple chemicals in living cells. The cladogenetic orthogonal light-up aptamers developed in this study and the simple strategy for rational designing of the signaling aptamers will provide innovative advances in the field of RNA-based bioimaging.

  • High-temperature adaptation of an OsNRT2.3 allele is thermoregulated by small RNAs. Reviewed International coauthorship International journal

    Climate change negatively affects crop yield, which hinders efforts to reach agricultural sustainability and food security. Here, we show that a previously unidentified allele of the nitrate transporter gene OsNRT2.3 is required to maintain high yield and high nitrogen use efficiency under high temperatures. We demonstrate that this tolerance to high temperatures in rice accessions harboring the HTNE-2 (high temperature resistant and nitrogen efficient-2) alleles from enhanced translation of the OsNRT2.3b mRNA isoform and the decreased abundance of a unique small RNA (sNRT2.3-1) derived from the 5' untranslated region of OsNRT2.3. sNRT2.3-1 binds to the OsNRT2.3a mRNA in a temperature-dependent manner. Our findings reveal that allelic variation in the 5' untranslated region of OsNRT2.3 leads to an increase in OsNRT2.3b protein levels and higher yield during high-temperature stress. Our results also provide a breeding strategy to produce rice varieties with higher grain yield and lower N fertilizer input suitable for a sustainable agriculture that is resilient against climate change.

  • Applicability of the nearest-neighbour model for pseudoknot RNAs. Reviewed International journal

    Chemical Communications   58 ( 40 )   5952 - 5955   2022.5

     More details

    The validity of the nearest-neighbour (NN) model was verified in an RNA pseudoknot (PK) structure. The thermodynamic parameters of the second hairpin stem (S2) region, which separates the PK from a hairpin structure, were monitored using CD and UV melting. Different PKs with identical NN base pairs in the S2 region exhibited similar thermodynamic parameters, highlighting the validity of the NN model in this RNA tertiary structure motif.

    本研究では、細胞内の化学的分子環境下での核酸の構造特性及びその熱安定性に着目し、これを制御する機能性分子を設計することで遺伝子発現の制御システムを開発することを目的とする。その中で、
    (1)天然の核酸構造及びその安定化エネルギーの観点から遺伝子発現の調節機構を『知る』。
    (2)細胞内環境下で核酸の構造形成及び構造変性を誘起する人工分子を合目的的に『生む』。
    (3)細胞内における遺伝子発現の制御に『活かす』。
    というステップを段階的に遂行することにより、効率的かつ合理的な機能性分子の創出を行う。特に、核酸の非標準構造(三重鎖構造、四重鎖構造、シュードノット構造など)の重要性に着目し、これらの核酸構造により緻密に調節される転写や翻訳の遺伝子発現過程を解析する。そして、合理的設計に基づいた機能性分子を用いて核酸構造の安定化エネルギーを調節することで、遺伝子発現過程の制御を目指す。
