Development of a Pseudocellular System to Quantify Specific Interactions Determining the G-Quadruplex Function in Cells International journal

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.

Choline Dihydrogen Phosphate Destabilizes G-Quadruplexes and Enhances Transcription Efficiency In Vitro and in Cells. International journal
Hisae Tateishi-Karimata, Naoki Sugimoto
ACS omega 9 ( 5 ) 5675 - 5682 2024.2
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-Cell Stability Prediction of RNA/DNA Hybrid Duplexes for Designing Oligonucleotides Aimed at Therapeutics. International journal

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.

Do ion channels control the formation of non-canonical nucleic acids and gene expression?
2020.7 - 2022.3
JSPS Grants-in-Aid for Scientific Research Grant-in-Aid for Challenging Research (Exploratory)
Sugimoto Naoki
The formation of nucleic acids of non-canonical structures induces mutations in biological reactions such as replication, transcription, and translation. In diseased cells, the molecular environments, especially ionic environments, are very different from that of normal cells due to overexpression (or inactivation) of disease-specific ion channels. These environmental differences are thought to affect the formation of non-canonical structures. In this study, we analyzed nucleic acid structures in the environments that mimic the molecular environment in diseased cells using physicochemical methods. As results, we clarified the mechanisms of stability changes of the non-canonical structures by intracellular environmental factors. Furthermore, we developed techniques to control gene expression by ion-nucleic acid interactions using small molecules and modified nucleic acids.
