Circular RNAs (circRNAs) have been repeatedly suggested as crucial effectors in modulating the development of multiple malignancies. The expression of circ_0002762 was predicted to be high in CSCC tissues in GEO dataset, but the functional role and underlying regulatory mechanism of circ_0002762 in CSCC was unclear. By series of functional assays and mechanism assays, supported by bioinformatics analysis, reverse transcription quantitative real-time polymerase chain reaction (RT-qPCR) analysis and western blot assays, we identified that circ_0002762 aberrantly up-regulated in CSCC, promoting CSCC cell migration and invasion. Mechanically, circ_0002762 was transcriptionally activated by Fork head box A1 (FOXA1). Moreover, the involvement of nuclear factor kappa B (NF-kB) signalling in circ_0002762 regulation mechanism in CSCC cells was ascertained. Additionally, circ_0002762, predominantly accumulated in cell cytoplasm, was proved to recruit Mov10 RISC complex RNA helicase (MOV10) to enhance RelA mRNA stability, thus affecting CSCC cell migration and invasion. In summary, FOXA1-mediated circ_0002762 up-regulation could enhance the migratory and invasive abilities of CSCC cells via the MOV10/RelA/NF-kB pathway.","PeriodicalId":21351,"journal":{"name":"RNA Biology","volume":" ","pages":"1-13"},"PeriodicalIF":3.6,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11934174/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143625775","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

RBPs may exhibit either anti-tumour or pro-tumour functions by influencing the TIME through the modulation of mRNAs and non-coding RNAs expression, as well as post-transcriptional modifications, primarily N6-methyladenosine (m6A). Aberrant regulation of RBPs, such as HuR and YBX1, typically enhances tumour immune escape and impacts prognosis of GI tumour patients. Further, while targeting RBPs offers a promising strategy for improving immunotherapy in GI cancers, the mechanisms by which RBPs regulate the TIME in these tumours remain poorly understood, and the therapeutic application is still in its early stages.

Notably, numerous mRNAs have annotated antisense RNAs (asRNAs). Because asRNAs resemble the largest group of lncRNAs and were identified to serve a general function in Saccharomyces cerevisiae, they are the focus of this review. In S. cerevisiae, the absence of RNA interference (RNAi) enables unbiased study and allowed researchers to investigate their roles in gene regulation more directly with intriguing results, summarized here. Expression of asRNA leads to the formation of double-stranded RNAs (dsRNAs) with the regarding sense counterpart, resulting in enhanced gene expression through preferential nuclear export.

The discovery that RNA can catalyse reactions in addition to encoding information opened new directions for engineering life and the possibility of life emerging from an RNA World. But a key missing ingredient for RNA-based biochemical systems is a mechanism to organize RNAs and regulate their activity. Lipids, which are essential for life and one of the most ancient biomolecules, can spontaneously self-assemble to form membranous bilayers, theoretically providing a surface that can serve to concentrate, protect, and regulate RNAs. This review explores the interactions between RNA and lipids, including the chemical basis for their interactions, and the implications for synthetic biology, RNA World, and modern cell biology. We discuss observations that RNA can selectively bind to lipid membranes in a sequence-dependent manner, and entertain how these interactions might be employed to engineer RNA-based sensors and regulatory elements in synthetic systems. The emerging field of RNA-lipid interactions opens new possibilities for engineering orthogonal biochemistries for synthetic cells, innovations in RNA therapeutics, and discovering potentially new facets of cellular regulation.","PeriodicalId":21351,"journal":{"name":"RNA Biology","volume":" ","pages":"1-28"},"PeriodicalIF":3.6,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12269668/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144560949","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we examined the genome-wide functions of Prp16 in the short intron-rich genome of the basidiomycete yeast Cryptococcus neoformans. The presence of multiple introns per transcript with intronic features that are more similar to those of higher eukaryotes makes it a promising model for studying spliceosomal splicing. Using a promoter-shutdown conditional Prp16 knockdown strain, we uncovered genome-wide but substrate-specific roles in C. neoformans splicing. The splicing functions of Prp16 are dependent on helicase motifs I and II, which are conserved motifs for helicase activity. A small subset of introns spliced independent of Prp16 activity was investigated to discover that exonic sequences at the 5' splice site (5'SS) and 3' splice site (3'SS) with stronger affinity for U5 loop 1 are a common feature in these introns. Furthermore, short (60-100nts) and ultrashort introns (<60nts) prevalent in the C. neoformans transcriptome were more sensitive to Prp16 knockdown than longer introns, indicating that Prp16 is required for the efficient splicing of short and ultrashort introns. We propose that stronger U5 snRNA-pre-mRNA interactions enable efficient transition of the spliceosome from the first to the second catalytic confirmation in Prp16 knockdown, particularly for short introns and introns with suboptimal features. This study provides insights into fine-tuning spliceosomal helicase function with variations in cis-element features.","PeriodicalId":21351,"journal":{"name":"RNA Biology","volume":" ","pages":"1-14"},"PeriodicalIF":3.6,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11913375/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143597670","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While primarily known for its antiviral role, emerging evidence suggests that PKR can play multifaceted roles in uninfected cells by interacting with cellular dsRNAs and protein regulators. The misactivation of PKR in uninfected cells is associated with many degenerative and inflammatory diseases. Even in healthy cells, PKR can affect gene expression by controlling mRNA splicing and gene-specific translation under stress. In addition, PKR can modulate cell cycle progression and promote cellular differentiation in several tissue types.

We have shown that Sfb inhibits protein synthesis at the level of initiation in cancer cells. However, the global snapshot of mRNA translation following Sorafenib-treatment has not been explored so far. In this study, we performed a genome-wide polysome profiling analysis in Sfb-treated HCC cells and demonstrated that, despite global translation repression, a set of different genes remain efficiently translated or are even translationally induced. We reveal that, in response to Sfb inhibition, translation is tuned, which strongly correlates with the presence of established mRNA cis-acting elements and the corresponding protein factors that recognize them, including DAP5 and ARE-binding proteins. At the level of biological processes, Sfb leads to the translational down-regulation of key cellular activities, such as those related to the mitochondrial metabolism and the collagen synthesis, and the translational up-regulation of pathways associated with the adaptation and survival of cells in response to the Sfb-induced stress. Our findings indicate that Sfb induces an adaptive reprogramming of translation and provides valuable information that can facilitate the analysis of other drugs for the development of novel combined treatment strategies based on Sfb therapy.","PeriodicalId":21351,"journal":{"name":"RNA Biology","volume":" ","pages":"1-11"},"PeriodicalIF":3.6,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11934173/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143670923","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
