One of the most important characteristics of SCs is their remarkable plasticity. In various injury contexts, SCs undergo a reprogramming process that generates specialized cells to promote tissue regeneration and repair. However, in pathological conditions, this same plasticity and regenerative potential can be hijacked. Different studies highlight the activation of the epithelial-mesenchymal transition (EMT) as a driver of SC phenotypic plasticity. Although SCs are not epithelial, their neural crest origin makes EMT activation crucial for their ability to adopt repair phenotypes, mirroring the plasticity observed during development. These adaptive processes are essential for regeneration. However, EMT activation in SCs-derived tumours enhances cancer progression and aggressiveness. Furthermore, in the tumour microenvironment (TME), SCs also acquire activated phenotypes that contribute to tumour migration and invasion by activating EMT in cancer cells. In this review, we will discuss how EMT impacts SC plasticity and function from development and tissue regeneration to pathological conditions, such as cancer.","PeriodicalId":19629,"journal":{"name":"Open Biology","volume":"15 3","pages":"240337"},"PeriodicalIF":4.5,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12105798/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143557485","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}

Diapause is triggered by environmental cues such as shortening of the photoperiod (lengthening of the night). The time of entry into diapause depends on the latitude of the insects' habitat, and this applies even within a species: populations living at higher latitudes enter diapause earlier in the year than populations living at lower latitudes. A long-standing question in biology is whether the internal circadian clock, which governs daily behaviour and serves as a reference clock to measure night length, shows similar latitudinal adaptations. To address this question, we examined the onset of diapause and various behavioural and molecular parameters of the circadian clock in the cosmopolitan fly, Drosophila littoralis, a species distributed throughout Europe from the Black Sea (41° N) to Arctic regions (69° N). We found that all clock parameters examined showed the same correlation with latitude as the critical night length for diapause induction. We conclude that the circadian clock has adapted to the latitude and that this may result in the observed latitudinal differences in the onset of diapause.","PeriodicalId":19629,"journal":{"name":"Open Biology","volume":"15 3","pages":"240403"},"PeriodicalIF":4.5,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12105796/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143557442","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}

Despite being a hallmark of eukaryotic cells, recent discoveries reveal that even prokaryotes exhibit nucleolus-like structures, hinting at ancient origins for nucleolar functions. This review explores the evolutionary journey of the nucleolus, tracing its roots back to early life and examining its structural and functional diversity across domains. We highlight key nucleolar proteins that play vital roles not only in ribosome production but also in regulating cell cycle, DNA repair and cellular stress, linking nucleolar activity directly to health and disease. Dysfunctions in nucleolar processes are implicated in cancer, ribosomopathies and neurodegenerative disorders, positioning the nucleolus as a critical target for innovative therapeutic strategies. As advanced imaging and molecular techniques unlock deeper insights into both canonical and mysterious non-canonical roles, the nucleolus stands as a model for how cellular microenvironments can evolve to meet complex biological demands. By addressing open questions surrounding the evolution of the nucleolus, its organization and diverse functions, the ideas presented here aim to contribute to the ongoing discussion, challenging traditional paradigms and suggesting new avenues for uncovering the fundamental principles that drive cellular life.","PeriodicalId":19629,"journal":{"name":"Open Biology","volume":"15 3","pages":"240330"},"PeriodicalIF":4.5,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11896706/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143605815","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}

Venom of jellyfish (Medusozoa) and sea anemones (Anthozoa) has been investigated since the 1970s, revealing a remarkable molecular diversity. Specifically, sea anemones harbour a rich repertoire of neurotoxic peptides, some of which have been developed in drug leads. However, venoms of the vast majority of Anthozoa species remain uncharacterized, particularly in the class Octocorallia. To fill this gap, we applied a proteo-transcriptomic approach to investigate venom composition in Eunicella singularis, a gorgonian species common in Mediterranean hard-bottom benthic communities. Our results highlighted the peculiarities of the venom of E. singularis with respect to sea anemones, which is reflected in the presence of several toxins with novel folds, worthy of functional characterization. A comparative genomic survey across the octocoral radiation allowed us to generalize these findings and provided insights into the evolutionary history, molecular diversification patterns and putative adaptive roles of venom toxins. A comparison of whole-body and nematocyst proteomes revealed the presence of different cytolytic toxins inside and outside the nematocysts. Two instances of differential maturation patterns of toxin precursors were also identified, highlighting the intricate regulatory pathways underlying toxin expression.","PeriodicalId":19629,"journal":{"name":"Open Biology","volume":"15 3","pages":"250015"},"PeriodicalIF":4.5,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11896702/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143605879","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}

However, how the host response partitions across these processes has not been directly tested in a single host-pathogen system, let alone in the context of known adaptive trajectories resulting from experimental evolution. Here, we compare a Drosophila melanogaster population adapted to oral infection with its natural pathogen Pseudomonas entomophila (BactOral), to its control population to find no evidence for behavioural changes but measurable differences in both resistance and disease tolerance. In BactOral, no differences were detected in bacterial intake or defecation, nor gut cell renewal. However, a measurable relative decrease in bacterial loads correlates with an increase in gut-specific anti-microbial peptide production, pointing to a strengthening in resistance. Additionally, we posit that disease tolerance also contributes to the response of BactOral through a tighter control of self- and pathogen-derived damage caused by bacteria exposure. This study reveals a genetically complex and mechanistically multi-layered response, possibly reflecting the structure of adaptation to infection in natural populations.","PeriodicalId":19629,"journal":{"name":"Open Biology","volume":"15 3","pages":"240265"},"PeriodicalIF":4.5,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11896704/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143605811","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}

However, most research has focused on the role of small RNAs, such as microRNAs, transfer RNAs and long non-coding RNAs, while protein-coding messenger RNAs (mRNAs) received less attention, even though they represent a substantial amount of the sperm RNA pool. Here, we curated mouse transcriptomic data from mature sperm and selected the most abundant mRNAs (above the 0.7 quantile). The obtained gene list was further filtered using two criteria: (i) mRNAs that are statistically higher in the one-cell embryo compared to the MII oocyte transcriptome, indicative of paternal mRNA contribution after fertilization; and (ii) mRNAs that are found bound to ribosomes in the one-cell embryo, indicative of positive translation in the zygote translatome. Our analysis identified 94 genes that form networks functionally involved in epigenetic chromatin organization, gene expression, RNA processing and translation during zygote genome activation. These findings underscore the significant role of sperm-borne mRNAs in early embryonic development and epigenetic inheritance, highlighting the need for further research to fully understand their functions.","PeriodicalId":19629,"journal":{"name":"Open Biology","volume":"15 3","pages":"240321"},"PeriodicalIF":4.5,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11936680/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143710687","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}

Atherosclerosis occurs when cholesterol and fat build up in plaques along blood vessel walls, restricting blood flow and preventing nutrients and oxygen from diffusing in and out of the bloodstream. High-density lipoprotein cholesterol (HDL) particles prevent the build-up of such plaques, removing excess cholesterol from the peripheral tissues and delivering it to the liver, where it can be removed from the body. This pathway is known as reverse cholesterol transport (RCT). Because HDL plays a key role in preventing plaque buildup, understanding how this molecule and RCT function in the body could help us develop much-needed new atherosclerosis therapies and prevention strategies. However, HDL metabolism is complex, and research on HDL has been less favoured than research investigating a much better-understood molecule, low-density lipoprotein cholesterol, as a treatment target. More specifically, the receptors involved in the process of taking up HDL within the liver and their relationships to one another, along with the mechanism of whole, or holoparticle uptake of HDL remain to be clarified. In this review, we discuss several outstanding mysteries in HDL metabolism, consider why previous clinical trials to improve cardiovascular health by modulating HDL levels have been unsuccessful and argue that understanding HDL metabolism is essential for crafting interventions to reduce cardiovascular disease risk.","PeriodicalId":19629,"journal":{"name":"Open Biology","volume":"15 2","pages":"240372"},"PeriodicalIF":4.5,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11835495/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143449644","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}

MAMs serve as dynamic communication hubs between the ER and mitochondria, orchestrating essential processes such as calcium signalling, lipid metabolism and cellular stress responses. Recent research has implicated MAM dysfunction in a wide array of conditions, including neurodegenerative diseases, metabolic disorders, cardiovascular diseases and cancer. The significant lack of biological knowledge behind MAM function emphasizes the need to study these enigmatic subcellular sites in greater detail. Key open questions include the mechanisms controlling MAM formation and disassembly, the full complement of MAM-associated proteins and how MAMs contribute to cellular decision-making and ageing processes. Advancing our understanding of MAMs through interdisciplinary approaches and cutting-edge technologies promises to reveal new insights into fundamental cellular signalling pathways and potentially lead to innovative therapeutic strategies for a range of diseases.
