However, many genes expressed in each cell type belong to widely conserved gene families with ancestrally ubiquitous expression. This raises a paradox: how have these genes evolved to shape cell type-specific traits without compromising their ancestral function in all other cells? This can be achieved through gene duplication and the origin of regulated, alternatively spliced exons, which generate new related proteins in the form of paralogous genes and alternative isoforms, respectively. Here, we explore how such new related proteins can contribute to the evolution of specific cell types while preserving broader ancestral roles. Specifically, we separately classify possible expression and functional fates for new related proteins and discuss their interplays and evolutionary likelihood. Our primary hypothesis is that expression specialization, mostly coupled with functional specialization, is the predominant fate for both paralogous genes and alternative isoforms throughout animal evolution.</p>","PeriodicalId":9264,"journal":{"name":"BioEssays","volume":" ","pages":"e202400202"},"PeriodicalIF":3.2,"publicationDate":"2025-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143490768","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study proposes adaptive hypotheses regarding its origins and phenotypic significance, suggesting that A-to-I editing enhances adaptability by alleviating genetic trade-offs. In metazoans, its emergence may have been driven by a development-defense trade-off associated with transposable element activation during the evolution of multicellularity. Late Devonian cooling and End-Permian warming are hypothesized to have driven the emergence of extensive A-to-I recoding in coleoid nervous systems and Sordariomycete sexual fruiting bodies, respectively. These adaptations may have influenced key evolutionary innovations, including the evolution of metazoan nervous systems, coleoid intelligence, and shell loss, and fungal sexual reproductive structures. Additionally, extensive A-to-I recoding is proposed to facilitate accelerated development and specific life-history strategies in both animals and fungi.

It serves as an orchestrated program for regulating gene expression. A previously reported role of IR is to induce intron-retained transcript (IRT) degradation via the nonsense-mediated mRNA decay (NMD) pathway, resulting in the downregulation of gene expression. However, accumulating evidence indicates that most IRTs are detained in the nucleus, and thus, IR can downregulate gene expression through the storage of IRTs in the nucleus. Although the importance of IRTs in gene expression regulation is well established, the detailed mechanisms remain unclear. Here, we propose a potential model to explain how IRTs are retained in the nucleus and respond to environmental changes or developmental transitions. Plenty of future studies are still ahead of us to fully dissect the biological function of IR and the underlying mechanisms.</p>\u0000 </div>","PeriodicalId":9264,"journal":{"name":"BioEssays","volume":"47 4","pages":""},"PeriodicalIF":3.2,"publicationDate":"2025-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143413341","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

After a period of increased rigor (no more “unpublished results” in papers, please), the rules seem to be relaxing somewhat. One example: referring to papers that have not undergone peer review (yet). Preprint repositories, such as bioRxiv, were around from the nineties but they really multiplied and got intensely used from about 2010 onward. To be honest, I have one manuscript, reflecting unfinished business, in such a repository myself. It has been there since 2013 and was, to my surprise, quoted on several occasions. I would still hesitate to do so myself and I will explain why.&lt;/p&gt;&lt;p&gt;Current Biology is an excellent journal with, for example, high-quality reviews that are a joy to read. Recently, I encountered a great paper about the evolutionary arms race with defense systems and anti-defense systems constantly evolving in prokaryotes on the one hand and phages and plasmids on the other [&lt;span&gt;1&lt;/span&gt;]. While perusing it, I stumbled upon a surprising fact: more than 5% (6 out of 103) of the references were to non-peer reviewed manuscripts on bioRxiv (deposited in 2023 and 2024). This example illustrates a pronounced development over the last decade: the use of preprints in such manner is now widely accepted [&lt;span&gt;2&lt;/span&gt;]. The positive aspects seem clear. Researchers can get rapid feedback and community review, as well as hasten dissemination, and all this in open access form. In mathematics, meeting abstracts and preprints are even standard and encouraged by major journals (the actual publication process is almost an afterthought). On the minus side stands the possible loss of one of the safeguards of scientific quality: peer review. However, on balance, the fact that the preprint is publicly available and is clearly identified as still having to undergo peer scrutiny, does help in neutralizing the potential harm of sub-standard research.&lt;/p&gt;&lt;p&gt;Indeed, the quality of the process of peer review itself could be under pressure. At the risk of anecdotal misrepresentation, I have the strong impression of seeing more mistakes in published articles nowadays as compared to a few decades before. This could just reflect a greater “publish or perish” pressure, as well as ever more complicated techniques and algorithms associated with massively increased datasets. However, rapidly evolving new areas of expertise, time pressures, and the “courtesy” basis of relatively unrewarded reviewing seem to be taking their toll. I will give just one example of an error that should have been spotted before publication, having to do with one of my own hobbyhorses, the mitochondrial electron transport chain (ETC). A highly interesting PNAS perspective looks at how modern-day ETCs could tell us something about how the earliest stages of evolution might have harnessed the potential available in electrochemical gradients [&lt;span&gt;3&lt;/span&gt;","PeriodicalId":9264,"journal":{"name":"BioEssays","volume":"47 4","pages":""},"PeriodicalIF":3.2,"publicationDate":"2025-02-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/bies.202500016","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143381585","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}
