Due to its diverse activities, Nanog has been identified in multiple cell types, including embryonic stem cells (ESCs) and cancer stem cells (CSCs). However, its molecular mechanism in chondrocytes remains unclear. In this study, we explored the effects of Nanog on chondrocytes and its interaction with chondrocyte-specific proteins. Chondrocytes were transfected with a Nanog cDNA vector, resulting in reduced expression of the chondrogenic markers Type II collagen and SOX9, as confirmed by western blot, RT-PCR, and immunofluorescence. Following siRNA transfection, the dedifferentiation effect of Nanog was reversed, restoring Type II collagen and SOX9 expression. We also discovered that the mechanism by which Nanog affects chondrocytes is closely linked to p53 and KLF4. Overexpression of KLF4 induced the phosphorylation of p53, and phospho-p53 directly inhibited Nanog expression. Moreover, the p53 activator Nutlin-3 A accelerated Nanog degradation, while the p53 inhibitor Pifithrin-α stabilized Nanog. Stabilized Nanog continued to promote chondrocyte dedifferentiation. Additional experiments were performed to identify the signaling pathways involved in Nanog-induced chondrocyte dedifferentiation. Our results showed that Nanog overexpression in chondrocytes significantly impacted the p38 kinase and AKT signaling pathways. Inhibition of p38 and AKT with SB203580 and LY294002 reduced Nanog expression and partially restored Type II collagen levels. Conversely, activation with anisomycin(ANS) and 740 Y-P enhanced Nanog expression, further reducing Type II collagen levels. To investigate Nanog’s role in early development in vivo, we injected Nanog expression vectors into zebrafish embryos. The injected zebrafish exhibited structural defects in craniofacial cartilage, confirming Nanog’s involvement in chondrocyte differentiation. These findings suggest that Nanog induces chondrocyte dedifferentiation, and this process can be modulated via the p53/KLF4 and p38/AKT pathways.</p></div>","PeriodicalId":574,"journal":{"name":"Functional & Integrative Genomics","volume":"25 1","pages":""},"PeriodicalIF":3.9,"publicationDate":"2025-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143583426","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our analysis identified two potential developmental trajectories of nasopharyngeal cancer cells, each exhibiting varying levels of stemness. We subsequently identified and validated a cancer stemness-related signature (STEM-signature). Single-cell profiling revealed enrichment of LAYN + CD8 + , CTLA4 + CD4 + , CXCL13 + CD4 + T cells, tumor-associated macrophages, and CD14 + monocytes in NPC patients with high stemness. NicheNet analysis suggested these immune cells regulate cancer stemness. Bulk transcriptomic analysis corroborated these findings, indicating a poor therapeutic response in high-stemness NPC. We predicted 13 potential drugs and identified 13 stemness-related miRNAs for NPC with high stemness. A Least Absolute Shrinkage and Selection Operator (LASSO) Cox regression model, based on this miRNA signature, predicted overall survival with an AUC of 0.71 and 0.72 in validation and testing sets, respectively. The miRNA-based stemness signature outperformed previous established signatures. Multivariate Cox regression analysis indicated that our prognostic signature could serve as an independent prognostic factor (p &lt; 0.001). Basic experiments showed that miR-300, miR-361-5p, miR-1246, and miR-1290 enhanced the stemness characteristics of NPC cells, promoting proliferation, invasion, and migration.

The findings suggested that PGK1 is upregulated in various cancer types and closely associated with poor prognosis. In terms of functional enrichment analysis, PGK1 primarily plays a role in glycolysis, hypoxia, EMT, and immune-related pathways. Furthermore, PGK1 is highly expressed in immune and malignant cells in the tumor microenvironment. Notably, PGK1 expression varied significantly among immune cells with distinct activation states. The results of experiments in vitro showed that PGK1 was significantly upregulated in ESCC cells, and its knockdown led to significant inhibition of proliferation, migration, and invasion while increasing cell apoptosis; conversely, overexpression promoted proliferation, migration, and invasion while reducing apoptosis.

This epigenetic modification plays a crucial role in maintaining cell identity and controlling differentiation, while its dysregulation is closely linked to cancer progression. PRC2 silences tumor suppressor genes, promoting cell proliferation, metastasis, epithelial-mesenchymal transition, and cancer stem cell plasticity. Enhancement of zeste homolog 2 (EZH2) overexpression or gain-of-function mutations have been observed in several cancers, including lymphoma, breast, and prostate cancers, driving aggressive tumor behavior and drug resistance. In addition to EZH2, other PRC2 components, such as embryonic ectoderm development (EED) and suppressor of zeste 12, are essential for complex stability and function. EED, in particular, enhances EZH2 activity and has emerged as a therapeutic target. Inhibitors like MAK683 and EED226 disrupt EED’s ability to maintain PRC2 activity, thereby reducing H3K27me3 levels and reactivating tumor suppressor genes. Valemetostat, a dual inhibitor of both EZH2 and EED, has shown promising results in aggressive cancers like diffuse large B-cell lymphoma and small-cell lung cancer, underlining the therapeutic potential of targeting multiple PRC2 components. PRC2’s role extends beyond gene repression, as it contributes to metabolic reprogramming in tumors, regulating glycolysis and lipid synthesis to fuel cancer growth. Furthermore, PRC2 is implicated in chemoresistance, particularly by modulating DNA damage response and immune evasion. Tazemetostat, a selective EZH2 inhibitor, has demonstrated significant clinical efficacy in EZH2-mutant cancers, such as non-Hodgkin lymphomas and epithelioid sarcoma. However, the compensatory function of enhancer of zeste homolog 1 (EZH1) in some cancers requires dual inhibition strategies, as seen with agents like UNC1999 and Tulmimetostat, which target both EZH1 and EZH2. Given PRC2’s multifaceted role in cancer biology, its inhibition represents a promising avenue for therapeutic intervention. The continued development of PRC2 inhibitors and exploration of their use in combination with standard chemotherapy or immunotherapy has great potential for improving patient outcomes in cancers driven by PRC2 dysregulation.</p><h3>Graphical abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":574,"journal":{"name":"Functional & Integrative Genomics","volume":"25 1","pages":""},"PeriodicalIF":3.9,"publicationDate":"2025-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143564407","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Previously, it was assumed that apoptosis and necrosis were the only means of cell death. Recent discoveries of alternative cell death pathways highlighted a complicated interplay between cell death regulation and its role in numerous human pathologies. DNA methylation is a universal epigenetic mechanism characterized by the covalent addition of a methyl group to cytosine in CpG dinucleotides. Alterations in DNA methylation patterns lead to the dysregulation of multiple cell death pathways. DNA methylome studies on cell death pathways have improved our understanding of the mechanism of various types of cell death, such as apoptosis, pyroptosis, necroptosis, ferroptosis, anoikis, autophagy, and cuproptosis. The irregular DNA methylation patterns of genes encoding proteins linked to multiple cell death pathways could underlie resistance to cell death. Dysregulation of cell death is linked to ailments in humans, such as cancer. However, unlike genetic alterations, DNA methylation is reversible, making it extremely interesting for therapeutics considering the potential use of DNA methyltransferase inhibitors. Furthermore, tumor microenvironment and genetic heterogeneity of cancers may influence the methylation-dependent regulation of cell death, contributing to tumor progression and therapeutic resistance. Understanding how DNA methylation influences cell death pathways may illuminate the underlying causes of cancer. This review explores the significance of the DNA methylation patterns of key genes involved in cell death pathways, emphasizing their connections and identifying potential gaps that could be exploited for developing epigenetic therapies targeting cancer.</p></div>","PeriodicalId":574,"journal":{"name":"Functional & Integrative Genomics","volume":"25 1","pages":""},"PeriodicalIF":3.9,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143527613","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Its molecular mechanism includes steps that occur in a sequence, starting from a break in a double strand to repair. After a double-strand break in the DNA strand, the repairing of DNA done via Homology-Directed Repair (HDR) is considered important in different organisms as it is ideal for precise genome editing and the reduction of unintended mutations. Still, it is mostly dominated by the Non-Homologous End Joining (NHEJ) pathway. A recent study by Cullot et al. published in <i>Nature Biotechnology</i> showed interesting features of AZD7648 (a DNA-PKcs inhibitor) that increase the probability of HDR event while DNA repairing (Cullot et al. 2024).</p></div>","PeriodicalId":574,"journal":{"name":"Functional & Integrative Genomics","volume":"25 1","pages":""},"PeriodicalIF":3.9,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10142-025-01560-x.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143521675","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
