The hypoxic bone marrow environment imparts peculiar metabolic characteristics to hematopoietic processes. Here, we discuss the internal metabolism of HSCs and describe external influences exerted on HSC metabolism by the bone marrow niche environment. Importantly, we suggest that the metabolic environment and metabolic cues are intertwined with HSC cell fate, and are crucial for hematopoietic processes. Metabolic dysregulation within the bone marrow niche during acute stress, inflammation, and chronic inflammatory conditions can lead to reduced HSC vitality. Additionally, we raise questions regarding metabolic stresses imposed on HSCs during implementation of stem cell protocols such as allo-SCT and gene therapy, and the potential ramifications. Enhancing our comprehension of metabolic influences on HSCs will expand our understanding of pathophysiology in the bone marrow and improve the application of stem cell therapies.</p>","PeriodicalId":9264,"journal":{"name":"BioEssays","volume":"47 2","pages":""},"PeriodicalIF":3.2,"publicationDate":"2024-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11755706/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142590176","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}

Some cells have been successful in solitude, some moved into cooperatives (i.e., multicellular organisms), but one additional strategy emerged. Throughout eukaryotes, many of the diverse multicellular cooperatives took life in partnership one step further. These cells came together and lost their singularity in the expanse of syncytial life. Recently in our search for this elusive “how”, we discovered the intriguing peculiarity of a nuclear, RNA-binding protein living a second life as a fusion manager at the surface of developing osteoclasts, ushering them into syncytia 1. It is from here that we will develop several thoughts about the advantages of multinucleated cells and discuss how these fusing cells pass through several hallmarks of cell death. We will propose that cell fusion shares much with cell death because cell fusion is a death of sorts for the cells that undergo it – a death of the life that was and the beginning of new life in a community without borders.</p>","PeriodicalId":9264,"journal":{"name":"BioEssays","volume":"47 2","pages":""},"PeriodicalIF":3.2,"publicationDate":"2024-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11755699/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142590162","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}

Cancer cells with elevated IFN-stimulated gene (ISG) scores, representing a viral mimicry-primed state, are particularly sensitive to PARP7 inhibition. This review focuses on the endogenous sources of NA in cancer and the potential to exploit elevated aberrant self-NA in cancer therapy. We describe strategies to increase cytoplamic NA levels, including targeting epigenetic control, DNA damage response, and mitochondrial function. We also discuss targeting RNA processing pathways, such as splicing and RNA editing, to enhance the immunostimulatory potential of existing NA.

Although excess intake of energetic macronutrients is implicated in causing obesity, ongoing debate centers on whether sugar or fat or both are driving the rising obesity rates. This has led to competing models of obesity such as the “Carbohydrate Insulin Model”, the “Energy Balance Model”, and the “Fructose Survival Hypothesis”. Conflicting evidence from studies designed to focus on individual energetic macronutrients or energy rather than macronutrient mixtures underlies this disagreement. Recent research in humans and animals employing the nutritional geometry framework (NGF) emphasizes the importance of considering interactions among dietary components. Protein interacts with carbohydrates, fats, and dietary energy density to influence both calorie intake (“protein leverage”) and, directly and indirectly, metabolic physiology and adiposity. Consideration of these interactions can help to reconcile different models of obesity, and potentially cast new light on obesity interventions.</p>","PeriodicalId":9264,"journal":{"name":"BioEssays","volume":"47 2","pages":""},"PeriodicalIF":3.2,"publicationDate":"2024-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142590179","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}

These genes have been extensively studied, under the assumption that they represent valid proxies for species-specific genes. Here, we critically evaluate taxonomic, phylogenetic, and sequence evolution evidence showing that orphan genes belong to a range of evolutionary ages and thus cannot be assigned to a single lineage. Furthermore, we show that the processes generating orphan genes are substantially more diverse than generally thought and include horizontal gene transfer, transposable element domestication, and overprinting.
