Abstract
Nucleic acid-based therapy has been emerging as a new strategy with great potential for the treatment of numerous diseases, especially those caused by gene defects. In this context, biotechnology plays a critical role on establishing suitable processes for biopharmaceuticals manufacturing, while the purification step still imposes a major burden. Affinity chromatography using amino acids as specific ligands has been successfully applied for plasmid DNA purification. In this protocol, we describe the process for nucleic acids production and extraction, as well as the chromatographic matrix synthesis for separation between DNA and RNA. This novel arginine-macroporous support presents excellent binding capacity and great robustness for nucleic acids isolation.

Efficient Isolation of Bacterial RNAs Using Silica-Based Materials Modified with Ionic Liquids. Life (Basel) 2021; 11:life11101090. [PMID: 34685465 PMCID: PMC8536996 DOI: 10.3390/life11101090] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2021] [Revised: 10/11/2021] [Accepted: 10/13/2021] [Indexed: 11/17/2022] Open
Abstract
High quality nucleic acids (with high integrity, purity, and biological activity) have become indispensable products of modern society, both in molecular diagnosis and to be used as biopharmaceuticals. As the current methods available for the extraction and purification of nucleic acids are laborious, time-consuming, and usually rely on the use of hazardous chemicals, there is an unmet need towards the development of more sustainable and cost-effective technologies for nucleic acids purification. Accordingly, this study addresses the preparation and evaluation of silica-based materials chemically modified with chloride-based ionic liquids (supported ionic liquids, SILs) as potential materials to effectively isolate RNAs. The investigated chloride-based SILs comprise the following cations: 1-methyl-3-propylimidazolium, triethylpropylammonium, dimethylbutylpropylammonium, and trioctylpropylammonium. All SILs were synthesized by us and characterized by solid-state 13C Nuclear Magnetic Resonance (NMR), Scanning Electron Microscopy (SEM), elemental analysis, and zeta potential measurements, confirming the successful covalent attachment of each IL cation with no relevant changes in the morphology of materials. Their innovative application as chromatographic supports for the isolation of recombinant RNA was then evaluated. Adsorption kinetics of transfer RNA (tRNA) on the modified silica-based materials were investigated at 25 °C. Irrespective to the immobilized IL, the adsorption experimental data are better described by a pseudo first-order model, and maximum tRNA binding capacities of circa 16 µmol of tRNA/g of material were achieved with silica modified with 1-methyl-3-propylimidazolium chloride and dimethylbutylpropylammonium chloride. Furthermore, the multimodal character displayed by SILs was explored towards the purification of tRNA from Escherichia coli lysates, which in addition to tRNA contain ribosomal RNA and genomic DNA. The best performance on the tRNA isolation was achieved with SILs comprising 1-methyl-3-propylimidazolium chloride and dimethylbutylpropylammonium chloride. Overall, the IL modified silica-based materials represent a more efficient, sustainable, and cost-effective technology for the purification of bacterial RNAs, paving the way for their use in the purification of distinct biomolecules or nucleic acids from other sources.

Abstract
The knowledge about non-coding RNAs (ncRNAs) is rapidly increasing with new data continuously emerging, regarding their diverse types, applications, and roles. Particular attention has been given to ncRNA with regulatory functions, which may have a critical role both in biological and pathological conditions. As a result of the diversity of ncRNAs and their ubiquitous involvement in several biologic processes, ncRNA started to be considered in the biomedical field, with immense potential to be exploited either as biomarkers or as therapeutic agents in certain pathologies. Indeed, ncRNA-based therapeutics have been proposed in many disorders and some even reached clinical trials. However, to prepare an RNA product suitable for pharmacological applications, certain criteria must be fulfilled, and it has to be guaranteed RNA purity, stability, and bioactivity. So, in this review, the different types of ncRNAs are identified and characterized, by describing their biogenesis, functions, and applications. A perspective on the main challenges and innovative approaches for the future and broad therapeutic application of RNA is also presented.

Abstract
Nucleic acids are relevant biopolymers in therapy and diagnosis, for which their purity and biological activity are of crucial relevance. However, these features are difficult to achieve by cost-effective methods. Herein, we report the functionalization of a macroporous chromatographic support functionalized with an ionic liquid (IL) with remarkable performance to purify nucleic acids. An initial screening with distinct IL chemical structures supported in silica was carried out, allowing to identify the IL 1-methyl-3-propylimidazolium chloride as the most promising ligand. A chromatographic macroporous matrix able to be used in preparative liquid chromatography was then functionalized and binding/elution studies were performed. The IL 1-methyl-3-propylimidazolium chloride acts as a multimodal ligand with a remarkable dynamic binding capacity. This macroporous support allows the (one-step) purification of nucleic acids, namely small RNAs, ribosomal RNA, and genomic DNA, from a bacterial lysate, and can be regenerated and reused without compromising its separation performance.

Abstract
Recent findings in genome-wide transcriptomics revealed that RNAs are involved in almost every biological process, across all domains of life. The characterization of native RNAs of unknown function and structure is particularly challenging due to their typical low abundance in the cell and the inherent sensitivity toward ubiquitous RNA degrading enzymes. Therefore, robust in vitro synthesis and extensive work-up methods are often needed to obtain samples amenable for biochemical, biophysical, and structural studies. Here, we present a protocol that combines the most recent advances in T7 in vitro transcription methodology with reverse phase ion pairing and ion exchange HPLC purification of RNAs for the production of yield-optimized large-scale samples. The method is easy to follow, robust and suitable for users with little or no experience within the field of biochemistry or chromatography. The complete execution of this method, for example, for production of isotopically labeled NMR samples, can be performed in less than a week.

Abstract
Genome-derived noncoding RNAs (ncRNAs), including microRNAs (miRNAs), small interfering RNAs (siRNAs), and long noncoding RNAs (lncRNAs), play an essential role in the control of target gene expression underlying various cellular processes, and dysregulation of ncRNAs is involved in the pathogenesis and progression of various diseases in virtually all species including humans. Understanding ncRNA biology has opened new avenues to develop novel RNA-based therapeutics. Presently, ncRNA research and drug development is dominated by the use of ncRNA mimics that are synthesized chemically in vitro and supplemented with extensive and various types of artificial modifications and thus may not necessarily recapitulate the properties of natural RNAs generated and folded in living cells in vivo. Therefore, there are growing interests in developing novel technologies for in vivo production of RNA molecules. The two most recent major breakthroughs in achieving an efficient, large-scale, and cost-effective fermentation production of recombinant or bioengineered RNAs (e.g., tens of milligrams from 1 L of bacterial culture) are (1) using stable RNA carriers and (2) direct overexpression in RNase III-deficient bacteria, while other approaches offer a low yield (e.g., nano- to microgram scales per liter). In this article, we highlight these novel microbial fermentation-based technologies that have shifted the paradigm to the production of true biological ncRNA molecules for research and development.

Abstract
Antisense oligonucleotides have been successfully investigated for the treatment of different types of diseases. Detection and determination of antisense oligonucleotides and their metabolites are necessary for drug development and evaluation. This review focuses mainly on the first step of the analysis of oligonucleotides i.e. the sample preparation stage, and in particular on the techniques used for liquid chromatography and liquid chromatography coupled with mass spectrometry. Exceptional sample preparation techniques are required as antisense oligonucleotides need to be determined in complex biological matrices. The text discusses general issues in oligonucleotide sample preparation and approaches to their solution. The most popular techniques i.e. protein precipitation, protein enzyme digestion and liquid-liquid extraction are reviewed. Solid phase extraction methods are discussed and the issues connected with the application of each method are highlighted. Other newly reported promising techniques are also described. Finally, there is a summary of actually used techniques and the indication of the direction of future research.

Abstract
RNA interference-based technologies have emerged as an attractive and effective therapeutic option with potential application in diverse human diseases. These tools rely on the development of efficient strategies to obtain homogeneous non-coding RNA samples with adequate integrity and purity, thus avoiding non-targeted gene-silencing and related side-effects that impair their application onto pre-clinical practice. These RNAs have been preferentially obtained by in vitro transcription using DNA templates or via chemical synthesis. As an alternative to overcome the limitations presented by these methods, in vivo recombinant production of RNA biomolecules has become the focus in RNA synthesis research. Therefore, using pre-miR-29b as a model, here it is evaluated the time-course profile of Escherichia coli and Rhodovolum sulfidophilum microfactories to produce this microRNA. As the presence of major host contaminants arising from the biosynthesis process may have important implications in the subsequent downstream processing, it is also evaluated the production of genomic DNA and host total proteins. Considering the rapidly growing interest on these innovative biopharmaceuticals, novel, more cost-effective, simple and easily scaled-up technologies are highly desirable. As microRNA recombinant expression fulfills those requirements, it may take the leading edge in the methodologies currently available to obtain microRNAs for clinical or structural studies.
