Its pathogenesis is multifactorial involving inflammation and immune dysregulation. Proinflammatory TNFα/NFκB signaling is believed to play a cardinal role in ulcerative colitis. Growing evidence indicates the molecular interactions between the cellular metabolites and different phases of inflammation. This study aims to identify the metabolites that can inhibit TNFα/NFκB signaling and are potentially therapeutic against various TNFα-associated inflammatory diseases, particularly inflammatory bowel diseases. We performed <em>in vitro</em> and <em>in vivo</em> screening of cellular metabolites to inhibit TNFα/NFκB signaling. Multiple confirmation assays, including NFκB translocation, quantitative real-time PCR, ELISA, immunofluorescence staining, and RNA sequencing analysis were executed. Drug affinity-responsive target stability assay with proteomics was utilized for target identification. cPLA2 ablated mice with dextran sodium sulfate-induced colitis were employed to assess pyruvate's dependence on its molecular target in attenuating ulcerative colitis pathogenesis. Metabolite screening and subsequent validation with multiple approaches led to the isolation of pyruvate, a glycolytic metabolite, and a critical node in several metabolic pathways, as a novel inhibitor of TNFα/NFκB signaling. Importantly, pyruvate suppressed inflammation, preserved colonic histology, maintained tight junction proteins, and regulated permeability in the ulcerative colitis model. Additionally, cPLA2 was identified as a previously unknown target of pyruvate and pyruvate largely lost its therapeutic effects against ulcerative colitis in cPLA2-deficient mice. Conclusively, this study not only unveils pyruvate as an antagonist of TNFα/NFκB signaling and therapeutic intervention against colitis but also provides mechanistic insight into the mode of action of pyruvate.</div></div>","PeriodicalId":12689,"journal":{"name":"Genes & Diseases","volume":"12 5","pages":"Article 101571"},"PeriodicalIF":6.9,"publicationDate":"2025-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144322050","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Overexpression and knockdown of PDE4DIP were constructed in H9C2 cells and neonatal Sprague–Dawley rat primary cardiomyocytes, respectively.

Cell scratching and CCK-8 assays were employed to detect cell migration and proliferation abilities of H9C2, respectively. We found that PDE4DIP expression was increased in the LVNC-derived human-induced pluripotent stem cell-derived cardiomyocytes compared with normal subjects. Furthermore, overexpression of PDE4DIP induced cytoskeletal disorganization, decreased ATP content and cell migration, and increased cell proliferation and mitochondrial vacuolation. Moreover, the knockdown of PDE4DIP promoted cytoskeleton formation and contributed to increased ATP content and elevated cell migration. Mechanically, overexpression of PDE4DIP inhibited cell polarity-, skeleton-, and Rho-ROCK signaling-related genes and proteins, which could be increased by knockdown of PDE4DIP, suggesting that a critical regulation of PDE4DIP to Rho-ROCK pathway.

Insulin-like growth factor-2 mRNA-binding protein 1 (IGF2BP1), a member of a conserved family of single-stranded RNA-binding proteins, has recently been identified as a vital m6A reading protein. IGF2BP1 is highly expressed in various tumors and is associated with poor prognosis and treatment resistance. Furthermore, previous studies have shown that IGF2BP1 plays critical roles in regulating various cancer hallmarks, including sustained cell proliferation, cell death resistance, activation of invasion and metastasis, deregulated cellular energetics, immune evasion, and unlocking phenotypic plasticity. IGF2BP1 could promote the expression of cancer-related genes by recognizing their m6A sites, thereby altering cell characteristics, and eventually, malignancy. Therefore, IGF2BP1 might be a potential target for tumor diagnosis and anti-tumor therapeutic strategies. This review summarizes the current knowledge on the functional roles and underlying molecular mechanisms of IGF2BP1 in regulating cancer hallmarks. Moreover, we discuss the prospects of IGF2BP1 as a potential tumor diagnosis marker, as well as a potential target for an anti-tumor therapeutic strategy.</div></div>","PeriodicalId":12689,"journal":{"name":"Genes & Diseases","volume":"12 5","pages":"Article 101567"},"PeriodicalIF":6.9,"publicationDate":"2025-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144271408","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The cooperative and competitive interactions among these cellular components contribute to the proliferation, progression, metastasis, and immune evasion of osteosarcoma. Alterations in bone-related cells, resulting from oncogenic changes, can rapidly increase bone density or aggravate bone loss, thereby promoting the survival of osteosarcoma cells. During the progression of osteosarcoma, genetic alterations in tumor cells lead to changes in extracellular matrix components, influencing the variation in cell-secreted factors, promoting immunosuppression within the tumor microenvironment, and consequently affecting tumor proliferation and progression. This review summarizes the roles of tumor microenvironment components in the pathogenesis of osteosarcoma and discusses existing therapeutic targets.

However, the intricate mechanisms driving this function of BMP9 remain elusive. This study endeavors to investigate the potential role of sirtuin 5 (SIRT5) in enhancing BMP9's osteogenic capacity and decipher the underlying molecular pathways. To achieve this aim, we employed real-time PCR, western blotting, histochemical staining, and a cranial defect repair model to assess the impact of SIRT5 on BMP9-mediated osteogenesis. We utilized real-time PCR, western blotting, immunofluorescent staining, and immunoprecipitation assay to explore the associated mechanisms. Our results revealed that SIRT5 significantly up-regulated BMP9-induced osteogenic markers, while SIRT5 knockdown reduced their expression. Concurrently, hypoxia-inducible factor 1 subunit alpha (HIF-1α) level was increased by SIRT5, but reduced by SIRT5 knockdown. Notably, HIF-1α potentiated the SIRT5's ability to strengthen BMP9's osteogenic potential, whereas HIF-1α silencing reduced this effect, which was confirmed by bone defect repair assay. The acetylation and malonylation levels of HIF-1α were reduced by SIRT5, which may enhance its stability to promote BMP9's osteogenic effect. Conversely, SIRT5 knockdown reversed these effects and promoted the degradation of HIF-1α. Collectively, our results demonstrated that the BMP9's osteogenic potential could be promoted by SIRT5, potentially through stabilizing HIF-1α by reducing its acetylation and malonylation modification.

Lactate accumulations play pleiotropic roles in disease progression through metabolic rearrangements and epigenetic modifications. Monocarboxylate transporter 4 (MCT4) is highly expressed in hepatocytes and responsible for transporting intracellular lactate out of the cell. To explore whether elevated MCT4 levels played any role in NAFLD development, we overexpressed and silenced MCT4 in hepatocytes and performed a comprehensive <em>in vitro</em> and <em>in vivo</em> analysis. Our results revealed that MCT4 overexpression down-regulated the genes for lipid synthesis while up-regulating the genes involved in lipid catabolism. Conversely, silencing MCT4 expression or inhibiting MCT4 expression led to the accumulation of intracellular lipid and glucose metabolites, resulting in hepatic steatosis. In a mouse model of NAFLD, we found that exogenous MCT4 overexpression significantly reduced lipid metabolism and alleviated hepatocellular steatosis. Mechanistically, MCT4 alleviated hepatic steatosis by regulating a group of hub genes such as <em>Arg2</em>, <em>Olr1</em>, <em>Cd74</em>, <em>Mmp8, Irf7</em>, <em>Spp1</em>, and <em>Apoe</em>, which in turn impacted multiple pathways involved in lipid metabolism and inflammatory response, such as PPAR, HIF-1, TNF, IL-17, PI3K-AKT, Wnt, and JAK-STAT.
