Special Issue Information

Dear Colleagues,

Recent advances in molecular biology have enabled the discovery and characterization of an unexpected multitude of RNA molecules involved in various physiological processes and have shed new light on the complex network of molecular interactions that occur in each cell to determine its fate. Many of these transcripts originate from apparently non-functional parts of the genome and are rapidly degraded. However, experimental studies have shown that some classes of ncRNAs, such as lncRNAs and microRNAs, are involved in virtually all cellular processes and direct widespread gene regulation at transcriptional and posttranscriptional levels, respectively. More controversial is the function of circRNAs, although the role of miRNA regulator has been convincingly demonstrated for some of them. Many ncRNAs have been proposed as new potential biomarkers and therapeutic targets. Overall, considerable progress has been achieved in deconstructing ncRNA-driven cellular homeostasis and its deregulation in pathologies, and the generation of massive, high-resolution datasets is rapidly transforming the classical vision of sole-protein cellular pathways in a more sophisticated protein–ncRNAs–genes interaction network. A key challenge at this point is to build the appropriate bioinformatics tools to integrate different datasets in order to model the connections and their functional role.

This Special Issue focuses on the latest advances in proteins and ncRNAs’ interactions and functions. The topics of interest include, but are not limited to:

  • Characterization of protein and RNA interactions.
  • Description of ncRNA regulatory networks.
  • Latest technical approaches to investigate protein and RNA function and localization.
  • Databases to annotate interaction data sets.
  • Bioinformatics tools to predict interactions or integrate data.

The isothermal amplification of nucleic acids refers to processes that quickly increase the amount of DNA at a constant temperature. These methods are mainly developed as alternatives to PCR for cases in which the application of a thermal cycler is not possible or the assay method must be as rapid as possible. We have developed a new method of isothermal amplification based on the formation of hairpins at the ends of DNA fragments containing palindromic sequences and increased by the hydrolysis of one or both DNA strands by restriction endonuclease, known as hairpin-assisted isothermal reaction (HAIR). The key steps in HAIR are the formation of a self-complementary hairpin and the DNA breakage introduced by nickase. The end hairpins facilitate primer-free amplification, the amplicon strand cleavage by nickase produces additional 3′ ends that serve as new amplification points, and the amount of DNA can increase exponentially. The rate of amplification in HAIR is more than five times the rate of loop-mediated isothermal amplification (LAMP), and the total amount of DNA product of HAIR is more than double the amount of the LAMP product.

Eukaryotic cells are intracellularly divided into several compartments that provide spatiotemporal control over biochemical reactions. Phase separation of proteins and RNA is emerging as an important mechanism underlying the formation of intracellular compartments that are not delimited by membranes. These structures are also known as biomolecular condensates and have been shown to serve a myriad of cellular functions, such as organization of cytoplasm and nucleoplasm, stress response, signal transduction, gene regulation, and immune response. Here, the author will summarize our current understanding of intracellular phase separation, its biological functions, and how this phenomenon is regulated in eukaryotic cells. Additionally, the author will review recent evidence of the role of biomolecular condensates in the development of pathophysiological conditions, with special emphasis on cancer and immune signaling.

It is commonly understood that RNA-binding proteins crucially determine the fate of their target RNAs. Vice versa, RNAs are becoming increasingly recognized for their functions in protein regulation and the dynamics of RNA-protein complexes. Long non-coding RNAs are emerging as potent regulators of proteins that exert unknown RNA-binding properties and moonlighting functions. A vast array of RNA- and protein-centric techniques have been developed for the identification of protein and RNA targets, respectively, including unbiased protein mass spectrometry and next-generation RNA sequencing as readout. Determining true physiological RNA and protein targets is challenging as RNA–protein interaction is highly dynamic, tissue- and cell-type-specific, and changes with the environment. Here I review current techniques for the analysis of RNA–protein interactions in living cells and in vitro. RNA-centric techniques are presented on the basis of cross-linking or the use of alternative approaches. Protein-centric approaches are discussed in combination with high-throughput sequencing. Finally, the impact of mutations in RNA–protein complexes on human disease is highlighted. Full article

Epitranscriptome refers to post-transcriptional modifications to RNA and their associated regulatory factors that can govern changes in an organism’s cells in response to various environmental stimuli. Recent studies have recognized over 170 distinct chemical signatures in RNA, and the list keeps expanding. These modifications are hypothesized to have roles beyond simply fine-tuning the structure and function of RNA, as studies have linked them to various infectious and noninfectious diseases in humans. Dedicated cellular machinery comprising of RNA-binding proteins (RBPs) that can write, erase, and read these modifications drives the regulation of the epitranscriptomic code, and as such influences RNA metabolism and homeostasis. Equally, perturbations in the function of RBPs may disrupt RNA processing, further implicating them in pathogenesis. As such, the mechanisms underlying RNA modifications and their association with RBPs are emerging areas of interest within the field of biomedicine. This review focuses on understanding epitranscriptomic modifications, their effects on RNA–RBPs interactions, and their influence on cellular processes. Full article
