Medicinal Chemistry Research 33 2079 - 2084 2024年8月
Pseudoknot (PK) is one of the prevalent and potential targets for drug discovery. It is still difficult to predict PK-forming regions within endogenous RNA transcripts because the intracellular environment consisting of various cellular agents has diverse effects on the structure and stability of nucleic acids. In this study, we have demonstrated the impact of the varied crowding conditions on the structural stability of pseudoknot RNA, emphasizing the distinct stabilities of PK structures depending on the crowding environment.

Intracellular chemical microenvironments, including ion concentrations and molecular crowding, play pivotal roles in cell behaviors, such as proliferation, differentiation, and cell death via regulation of gene expression. However, there is no method for quantitative analysis of intracellular environments due to their complexity. Here, we have developed a system for highlighting the environment inside of the cell (SHELL). SHELL is a pseudocellular system, wherein small molecules are removed from the cell and a crowded intracellular environment is maintained. SHELL offers two prominent advantages: (1) It allows for precise quantitative biochemical analysis of a specific factor, and (2) it enables the study of any cell, thereby facilitating the study of target molecule effects in various cellular environments. Here, we used SHELL to study G-quadruplex formation, an event that implicated cancer. We show that G-quadruplexes are more stable in SHELL compared with in vitro conditions. Although malignant transformation perturbs cellular K+ concentrations, environments in SHELL act as buffers against G-quadruplex destabilization at lower K+ concentrations. Notably, the buffering effect was most pronounced in SHELL derived from nonaggressive cancer cells. Stable G-quadruplexes form due to the binding of the G-quadruplex with K+ in different cancer cells. Furthermore, the observed pattern of G-quadruplex-induced transcriptional inhibition in SHELL is consistent with that in living cells at different cancer stages. Our results indicate that ion binding to G-quadruplexes regulates gene expression during pathogenesis.

G-quadruplexes in disease-related genes are associated with various biological processes and regulate disease progression. Although methods involving ligands and other techniques are available to stabilize G-quadruplexes, approaches for destabilizing G-quadruplexes remain limited. Here, we evaluated whether G-quadruplexes can be destabilized using choline dihydrogen phosphate (choline dhp), a highly biocompatible hydrated ionic liquid. Circular dichroism spectral measurements at increasing temperatures revealed that choline dhp destabilized G-quadruplexes more effectively than did KCl-containing solutions. Thermodynamic analysis indicated that destabilization occurred via an entropic contribution, suggesting that choline ions did not coordinate with the G-quartets, because of their large radii. Subsequently, plasmid DNAs containing G-quadruplexes were constructed, and transcription reactions were performed in nuclear extracts from living cells. G-quadruplexes repressed transcription, whereas the addition of choline dhp increased transcription. Although ionic liquids often inactivate biomolecules, choline dhp can be used to culture various cells. Furthermore, the transcription of template DNA containing the G-quadruplex was greatly enhanced in living MDA-MD-231 cells (aggressive human breast cancer cells) cultured with choline dhp. Our results show that choline dhp destabilizes G-quadruplexes in cells, indicating that choline dhp can regulate gene expression. Thus, choline dhp may be useful for regulating target disease-related genes.

In cells, the formation of RNA/DNA hybrid duplexes regulates gene expression and modification. The environment inside cellular organelles is heterogeneously crowded with high concentrations of biomolecules that affect the structure and stability of RNA/DNA hybrid duplexes. However, the detailed environmental effects remain unclear. Therefore, the mechanistic details of the effect of such molecular crowding were investigated at the molecular level by using thermodynamic and nuclear magnetic resonance analyses, revealing structure-dependent destabilization of the duplexes under crowded conditions. The transition from B- to A-like hybrid duplexes due to a change in conformation of the DNA strand guided by purine-pyrimidine asymmetry significantly increased the hydration number, which resulted in greater destabilization by the addition of cosolutes. By quantifying the individual contributions of environmental factors and the bulk structure of the duplex, we developed a set of parameters that predict the stability of hybrid duplexes with conformational dissimilarities under diverse crowding conditions. A comparison of the effects of environmental conditions in living cells and in vitro crowded solutions on hybrid duplex formation using the Förster resonance energy transfer technique established the applicability of our parameters to living cells. Moreover, our derived parameters can be used to estimate the efficiency of transcriptional inhibition, genome editing, and silencing techniques in cells. This supports the usefulness of our parameters for the visualization of cellular mechanisms of gene expression and the development of nucleic acid-based therapeutics targeting different cells.

Ligands that recognise specific i-motif DNAs are helpful in cancer diagnostics and therapeutics, as i-motif formation can cause cancer. Although the loop regions of i-motifs are promising targets for ligands, the interaction between a ligand and the loop regions based on sequence information remains unexplored. Herein, we investigated the loop regions of various i-motif DNAs to determine whether these regions specifically interact with fluorescent ligands. Crystal violet (CV), a triphenylmethane dye, exhibited strong fluorescence with the i-motif derived from the promoter region of the human BCL2 gene in a sequence- and structure-specific manner. Our systematic sequence analysis indicated that CV was bound to the site formed by the first and third loops through inter-loop interactions between the guanine bases present in these loops. As the structural stability of the BCL2 i-motif was unaffected by CV, the local stabilisation of the loops by CV could inhibit the interaction of transcription factors with these loops, repressing the BCL2 expression of MCF-7 cells. Our finding suggests that the loops of the i-motif can act as a novel platform for the specific binding of small molecules; thus, they could be utilised for the theranostics of diseases associated with i-motif DNAs.

Liquid–liquid phase separation (LLPS), which results in the formation of highly concentrated droplets of biomolecules, is involved in various physiological phenomena. We have performed a label-free quantification of the concentration of a G-quadruplex-forming RNA and an RGG peptide in a single droplet using Raman microscopy. The concentration ratio of the RNA to the peptide within the droplet was found to maintain even when the prepared concentration ratio of these two species was varied. This result indicates that electrostatic interactions between the RNA and the peptide induced the droplet formation. It was also shown that the RNA maintains its G-quadruplex structure inside the droplets.

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 査読あり 国際誌

Chem. Commun. 59 872 - 875 2023年1月
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.

Pressure-temperature control of activity of RNA polymerase ribozyme 査読あり 国際誌
S. Takahashi and N. Sugimoto
Biophys. Chem. 292 106914 2023年1月
A representative role of nucleic acids (DNA and RNA) is in the storage of genetic information. In contrast, RNAs act as ribozymes that catalyze various biochemical reactions. The “RNA world” hypothesis suggests that the origin of life was RNA because a ribozyme that shows RNA replication activity has been identified. However, prebiotic conditions in the RNA world remain unknown. In this study, we investigated the effect of high pressure and temperature on RNA replication using an RNA polymerase ribozyme tC9Y. We found that pressure accelerated the RNA replication activity of tC9Y ribozyme at higher temperatures than physiological conditions. Furthermore, molecular crowding by concentrated polyethylene glycol 200 (average molecular weight 200) synergistically enhanced the replication activity at higher pressure and temperature because the negative effect of a volumetric contribution of hydration on the tC9Y ribozyme activity decreased under crowding conditions. As a comparison, proteinaceous RNA polymerase that exists in the modern era did not show accelerated activity under high pressure and temperature. Thus, these results imply that the prebiotic conditions for the RNA world were at high pressure and temperatures under crowding conditions.

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.

We constructed a minimum liquid-liquid phase separation model system to form liquid droplets using only G-quadruplex-forming oligonucleotides and R- and G-rich oligopeptides. We found that the G-quadruplex structure is an essential component for RNA to form droplets with the peptide. Based on this model system and our findings, droplet redissolution via structure transition from a G-quadruplex to a duplex was achieved in a sequence-specific manner.
Liquid–liquid phase separation (LLPS) of biomacromolecules has been attracting attention as a novel phenomenon and a new phase in living cells.1 It is now evident that LLPS involving nucleic acids participates in the regulation of gene expression at various levels, including replication, transcription, RNA processing, localization, and translation.2 Dysfunction of LLPS is linked to the onset of viral infection,3 cancer,4 and neurodegenerative diseases.2 Although LLPS is induced by different molecular compositions, it is considered that LLPS of different molecular compositions has common assembly and disassembly mechanisms.5 Many of the protein motifs essential for LLPS are intrinsically disordered regions (IDRs) such as RGG motifs.6 Moreover, databases and prediction models of proteins undergoing LLPS have been established.7 Furthermore, fundamental properties of RNAs for inducing LLPS is becoming clear.8–11 RNA secondary structure-dependent LLPS has also been reported.12
Of note, the RGG domain derived from various RNA binding proteins (RBPs) selectively binds with G-quadruplexes (G4s), a non-canonical secondary structure of nucleic acids.13 G4 formed by guanine-rich sequences have been reported to induce LLPS in a structure-specific manner. Fragile X mental retardation protein (FMRP),14 SERPINE1 mRNA-binding protein 1 (SERBP1),15 and Histone H116 all induce LLPS with G4. The repetitive GGGGCC sequence, found within the C9orf72 gene, undergoes pathogenic expansion responsible for amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD).17 Repetitive expansion of GGC repeats on the FMR1 gene is considered as an onset mechanism of neurodegenerative diseases such as fragile X syndrome (FXS) and fragile X-associated tremor/ataxia syndrome (FXTAS).18 These sequences can fold to form G4 structures and induce aberrant RNA foci in the nucleus through sequestration of various RBPs.19 Although the characteristics of the various protein and nucleic acid sequences of droplets are becoming clearer, methods for regulating droplets have not yet been developed. Here, we developed a model system of LLPS based on oligonucleotides and oligopeptides to investigate the essential properties of RNA that directly induce and control LLPS.
A series of RNA oligonucleotides were designed to study their ability to undergo LLPS with a cationic peptide containing the RGG motif derived from FMRP (Table 1).13 FMR1 RNA and C9orf72 RNA are four repeats of GGC and GGGGCC, respectively, which may form a G4. sFMR1 RNA is a scrambled sequence of FMR1 RNA that does not form a G4. Comp-RNA is complementary to FMR1 RNA. dsRNA was designed to form an intramolecular duplex (a hairpin loop structure). The structure of the RNA oligonucleotides was studied by CD spectroscopy and UV melting curves (Fig. S1, ESI†). These results are consistent with each other and show that FMR1 RNA and c9orf72 RNA fold into parallel G4s, and the 1 : 1 mixture and dsRNA forms A-form duplexes in the experimental conditions. (See Fig. S1, ESI† for explanations of the CD spectra and UV melting curves).DOI: 10.1039/d2cc04366a

Hydration around nucleic acids, such as DNA and RNA, is an important factor not only for the stability of nucleic acids but also for their interaction with binding molecules. Thus, it is necessary to quantitatively elucidate the hydration properties of nucleic acids around a certain structure. In this study, volumetric changes in G-quadruplex (G4) RNA formation were investigated by systematically changing the number of G-quartet stacks under high pressure. The volumetric contribution at the level of each G4 structural unit revealed that the core G4 helix was significantly more dehydrated than the other parts, including the edges of G-quartets and loops. These findings will help in predicting the binding of G4 ligands on the surface of G4, depending on the chemical structure of the ligand and solution environment. Therefore, the preset volumetric parameter provides information that can predict molecular interactions in G4 formations during molecular crowding in cells.

The human telomere region is known to contain guanine-rich repeats and form a guanine-quadruplex (G4) structure. As telomeres play a role in the regulation of cancer progression, ligands that specifically bind and stabilize G4 have potential therapeutic applications. However, as the human telomere sequence can form G4 with various topologies due to direct interaction by ligands and indirect interaction by the solution environment, it is of great interest to study the topology-dependent control of replication by ligands. In the present study, a DNA replication assay of a template with a human telomere G4 sequence in the presence of various ligands was performed. Cyclic naphthalene diimides (cNDI1 and cNDI2) efficiently increased the replication stall of the template DNA at G4 with an anti-parallel topology. This inhibition was stability-dependent and topology-selective, as the replication of templates with hybrid or parallel G4 structures was not affected by the cNDI and cNDI2. Moreover, the G4 ligand fisetin repressed replication with selectivity for anti-parallel and hybrid G4 structures without stabilization. Finally, the method used, referred to as quantitative study of topology-dependent replication (QSTR), was adopted to evaluate the correlation between the replication kinetics and the stability of G4. Compared to previous results obtained using a modified human telomere sequence, the relationship between the stability of G4 and the effect on the topology-dependent replication varied. Our results suggest that native human telomere G4 is more flexible than the modified sequence for interacting with ligands. These findings indicate that the modification of the human telomeric sequence forces G4 to rigidly form a specific structure of G4, which can restrict the change in topology-dependent replication by some ligands.

The DNA G-quadruplex is known for forming a range of topologies and for the observed lability of the assembly, consistent with its transient formation in live cells. The stabilization of a particular topology by a small molecule is of great importance for therapeutic applications. Here, we show that the ruthenium complex Λ-[Ru(phen)2(qdppz)]2+ displays enantiospecific G-quadruplex binding. It crystallized in 1:1 stoichiometry with a modified human telomeric G-quadruplex sequence, GGGTTAGGGTTAGGGTTTGGG (htel21T18), in an antiparallel chair topology, the first structurally characterized example of ligand binding to this topology. The lambda complex is bound in an intercalation cavity created by a terminal G-quartet and the central narrow lateral loop formed by T10–T11–A12. The two remaining wide lateral loops are linked through a third K+ ion at the other end of the G-quartet stack, which also coordinates three thymine residues. In a comparative ligand-binding study, we showed, using a Klenow fragment assay, that this complex is the strongest observed inhibitor of replication, both using the native human telomeric sequence and the modified sequence used in this work.

In biological systems, the synthesis of nucleic acids, such as DNA and RNA, is catalyzed by enzymes in various aqueous solutions. However, substrate specificity is derived from the chemical properties of the residues, which implies that perturbations of the solution environment may cause changes in the fidelity of the reaction. Here, we investigated non-promoter-based synthesis of RNA using T7 RNA polymerase (T7 RNAP) directed by an RNA template in the presence of polyethylene glycol (PEG) of various molecular weights, which can affect polymerization fidelity by altering the solution properties. We found that the mismatch extensions of RNA propagated downstream polymerization. Furthermore, PEG promoted the polymerization of non-complementary ribonucleoside triphosphates, mainly due to the decrease in the dielectric constant of the solution. These results indicate that the mismatch extension of RNA-dependent RNA polymerization by T7 RNAP is driven by the stacking interaction of bases of the primer end and the incorporated nucleotide triphosphates (NTP) rather than base pairing between them. Thus, proteinaceous RNA polymerase may display different substrate specificity with changes in dielectricity caused by molecular crowding conditions, which can result in increased genetic diversity without proteinaceous modification.

The stability of Watson–Crick paired RNA/DNA hybrids is important for designing optimal oligonucleotides for ASO (Antisense Oligonucleotide) and CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats)–Cas9 techniques. Previous nearest-neighbour (NN) parameters for predicting hybrid stability in a 1 M NaCl solution, however, may not be applicable for predicting stability at salt concentrations closer to physiological condition (e.g. ∼100 mM Na+ or K+ in the presence or absence of Mg2+). Herein, we report measured thermodynamic parameters of 38 RNA/DNA hybrids at 100 mM NaCl and derive new NN parameters to predict duplex stability. Predicted ΔG°37 and Tm values based on the established NN parameters agreed well with the measured values with 2.9% and 1.1°C deviations, respectively. The new results can also be used to make precise predictions for duplexes formed in 100 mM KCl or 100 mM NaCl in the presence of 1 mM Mg2+, which can mimic an intracellular and extracellular salt condition, respectively. Comparisons of the predicted thermodynamic parameters with published data using ASO and CRISPR–Cas9 may allow designing shorter oligonucleotides for these techniques that will diminish the probability of non-specific binding and also improve the efficiency of target gene regulation.

Enhancement of the Catalytic Activity of Hammerhead Ribozymes by Organic Cations. 査読あり 国際誌
Shu-Ichi Nakano, Hirofumi Yamashita, Naoki Sugimoto
Chembiochem : a European journal of chemical biology 2021年7月
Catalytic turnover is important for the application of ribozymes to biotechnology. However, the turnover is often impaired because of the intrinsic high stability of base pairs with cleaved RNA products. Here, organic cations were used as additives to improve the catalytic performance of hammerhead ribozyme constructs that exhibit different kinetic behaviors. Kinetic analysis of substrate cleavage demonstrated that bulky cations, specifically tetra-substituted ammonium ions containing pentyl groups or a benzyl group, have the ability to greatly increase the turnover rate of the ribozymes. Thermal stability analysis of RNA structures revealed that the bulky cations promote the dissociation of cleaved products and refolding of incorrectly folded structures with small disruption of the catalytic structure. The use of bulky cations is a convenient method for enhancing the catalytic activity of hammerhead ribozymes, and the approach may be useful for advancing ribozyme technologies.
