The protein-coding genes are first transcribed as pre-mRNAs in the nucleus and undergo a series of RNA processing steps before being transported into the cytoplasm for translation. During RNA processing, most human genes (>95%) undergo alternative splicing to generate multiple mRNA isoforms from a single gene, which effectively diversifies the genome complexity. Since the splicing of most genes occurs co-transcriptionally, the regulation layers of gene expression often show functional interactions with each other. In this review, we provide a brief overview of alternative splicing regulation in three different layers (controlled by the splicing machinery, transcription process, and chromatin structure), emphasizing the regulatory roles of epigenetic modifications and the crosstalk between these layers. Specifically, we categorize the major effects of the epigenetic modifications on alternative splicing into three different types: by affecting transcription rate, splicing factor recruitment, or the expression/activity of splicing factor. The dysregulation of epigenetics and splicing are extremely common in cancer, we also discuss the potential mechanisms of how epigenetic changes can lead to splicing dysregulation and their functional consequences. We aim to provide insights into the complicated regulation of different gene expression layers, which will shed light on the novel approaches to modulate disease-related splicing dysregulation.

Due to these advantages, it has been used to study an array of complex human diseases. From broad, complex pathological conditions such as aging and neurodegenerative disease to newer uses such as SARS-CoV-2, yeast continues to offer new insights into how cellular processes are affected by disease and how affected pathways might be targeted in therapeutic settings. At the same time, the roles of RNA and RNA-based processes have become increasingly prominent in the pathology of many of these same human diseases, and yeast has been utilized to investigate these mechanisms, from aberrant RNA-binding proteins in amyotrophic lateral sclerosis to translation regulation in cancer. Here we review some of the important insights that yeast models have yielded into the molecular pathology of complex, RNA-based human diseases.

N⁶ -methyladenosine (m⁶ A) is the most abundant modification in eukaryotic messenger RNA (mRNA) and has also been detected in non-coding RNAs, including long non-coding RNA, ribosomal RNA, and small nuclear RNA. In general, m⁶ A marks can alter RNA secondary structure and initiate unique RNA-protein interactions that can alter splicing, mRNA turnover, and translation, just to name a few. Although m⁶ A marks in human RNAs have been known to exist since 1974, the structures and functions of methyltransferases responsible for writing m⁶ A marks have been established only recently. Thus far, there are four confirmed human methyltransferases that catalyze the transfer of a methyl group from S-adenosylmethionine (SAM) to the N⁶ position of adenosine, producing m⁶ A: methyltransferase-like protein (METTL) 3/METTL14 complex, METTL16, METTL5, and zinc-finger CCHC-domain-containing protein 4. Though the methyltransferases have unique RNA targets, all human m⁶ A RNA methyltransferases contain a Rossmann fold with a conserved SAM-binding pocket, suggesting that they utilize a similar catalytic mechanism for methyl transfer. For each of the human m⁶ A RNA methyltransferases, we present the biological functions and links to human disease, RNA targets, catalytic and kinetic mechanisms, and macromolecular structures. We also discuss m⁶ A marks in human viruses and parasites, assigning m⁶ A marks in the transcriptome to specific methyltransferases, small molecules targeting m⁶ A methyltransferases, and the enzymes responsible for hypermodified m⁶ A marks and their biological functions in humans. Understanding m⁶ A methyltransferases is a critical steppingstone toward establishing the m⁶ A epitranscriptome and more broadly the RNome.

All members share an RNA recognition motif (RRM), and a particular affinity for the GCAUG signature in target RNA molecules. The role of Rbfox, as a splice factor, deciding the tissue-specific inclusion/exclusion of an exon, depending on its binding position on the flanking introns, is well known. Rbfox often acts in concert with other splicing factors, and forms splicing regulatory networks. Apart from this canonical role, recent studies show that Rbfox can also function as a transcription co-factor, and affects mRNA stability and translation. The repertoire of Rbfox targets is vast, including genes involved in the development of tissue lineages, such as neurogenesis, myogenesis, and erythropoeiesis, and molecular processes, including cytoskeletal dynamics, and calcium handling. A second layer of complexity is added by the fact that Rbfox expression itself is regulated by multiple mechanisms, and, in vertebrates, exhibits tissue-specific expression. The optimum dosage of Rbfox is critical, and its misexpression is etiological to various disease conditions. In this review, we discuss the contextual roles played by Rbfox as a tissue-specific regulator for the expression of many important genes with diverse functions, through the lens of the emerging data which highlights its involvement in many human diseases. Furthermore, we explore the mechanistic details provided by studies in model organisms, with emphasis on the work with Drosophila.

Upon discovery, these proteins are typically classified as either DNA or RNA binding as defined by their in vivo functions; however, recent evidence suggests dual DNA and RNA binding by many of these proteins. High mobility group box (HMGB) proteins have a DNA binding HMGB domain, act as transcription factors and chromatin remodeling proteins, and are increasingly understood to interact with RNA as means to regulate gene expression. Herein, multiple layers of evidence that the HMGB family are dual DNA and RNA binding proteins is comprehensively reviewed. For example, HMGB proteins directly interact with RNA in vitro and in vivo, are localized to RNP granules involved in RNA processing, and their protein interactors are enriched in RNA binding proteins involved in RNA metabolism. Importantly, in cell-based systems, HMGB-RNA interactions facilitate protein-protein interactions, impact splicing outcomes, and modify HMGB protein genomic or cellular localization. Misregulation of these HMGB-RNA interactions are also likely involved in human disease. This review brings to light that as a family, HMGB proteins are likely to bind RNA which is essential to HMGB protein biology.
