The purpose of this study is to investigate the amount of copper, copper-associated genes DLAT and FDX1 oxidative stress (OS) status in obesity. Since there is a close relationship between OS and cuproptosis, evaluating the effect of various strategies to reduce OS, including quercetin (QUER) and caloric restriction (CR), is another goal of this study. In this study, 30 male BALB-C mice aged 8 weeks and weighing 25 g, including the groups receiving normal diet (ND), ND with QUER (15 mg/kg, IP) and CR, a high-fat diet (HFD) with the QUER, CR or a combination of both were used. The activities of antioxidant enzymes superoxide dismutase (SOD), glutathione peroxidase (GPX), and glutathione reductase (GR), amount of copper in the liver and kidney tissues, and expression of DLAT and FDX1 genes were measured in all studied groups. The amount of copper in the liver and kidney tissue as well as the expression of FDX1 and DLAT in the HFD group increased significantly compared with the ND group. QUER, CR or their combination could significantly reduce the amount of copper as well as the expression of FDX1 and DLAT in liver and kidney tissues. QUER and CR, also significantly increased the activity of GR, SOD and GPX in serum, liver, and kidney tissues. Based on the results, QUER, CR and especially the simultaneous use of both, was able to reduce the amount of copper and its related cuproptosis. These effects may reduce cuproptosis-associated cell death. Therefore, the use of antioxidants and CR may be a promising solution to protect the human body against the effects of cuproptosis in conditions like obesity.","PeriodicalId":93981,"journal":{"name":"DNA and cell biology","volume":" ","pages":"370-379"},"PeriodicalIF":0.0,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144033026","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

GC development is a multistep and multifactorial process, and the molecular characterization of the multistage progression of gastric lesions to GC is poorly understood. Induction of ferroptosis driven by iron-dependent phospholipid peroxidation ameliorates the malignant progression of GC. Here, we found that solute carrier family 47 member 1 (SLC47A1) promoted GC progression by regulating ferroptosis. Clinically, SLC47A1 was elevated during the progression of gastritis to GC, and its high expression was associated with poor prognosis in patients with GC. Knockdown of SLC47A1 significantly inhibited cell proliferation, colony formation, and tumor growth. Further studies revealed that SLC47A1 was a regulator of ferroptosis rather than apoptosis or necrosis. Knockdown of SLC47A1 promoted ferroptosis in GC cells, as evidenced by increased erastin-induced cytoplasmic membrane rupture, cell death, lipid peroxidation, and malondialdehyde levels. Mechanistically, GATA6 promoted SLC47A1 transcription, leading to elevated SLC47A1 expression and promoting ferroptosis in GC cells. In summary, our study revealed the significant role of SLC47A1 in the development and progression of GC through regulating ferroptosis. Targeting the GATA6/SLC47A1 axis may be a promising therapeutic strategy for GC.","PeriodicalId":93981,"journal":{"name":"DNA and cell biology","volume":" ","pages":"360-369"},"PeriodicalIF":0.0,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144047215","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

ChIP determines the genomic location of specific proteins or post-translational modifications at an individual locus or genome-wide. The protocol endures complexity; hence it is of utmost importance to identify the variable responsible for experimental erraticism. The most sensitive and critical step involves the chromatin fragmentation step. In the current study, the parameters required for chromatin shearing in the Kasumi-1 cell line have been optimized. To address this, the protocol includes the fixation of cells with formaldehyde followed by cell lysis and nuclei isolation. Further chromatin shearing using various sonication buffers and sonicator parameters was performed. Successful sonication was observed at the following settings: peak incident power of 150 W, duty factor 7.0%, cycles per burst 200, and water fill level 8 generating fragments of ∼250-600 bp in 7 min. To analyze enriched DNA sequences that are associated with the target protein ChIP coupled with quantitative PCR was performed. With this study, the optimal procedure has been standardized for a percentage of detergents, SDS (0.15%), DOC (0.05%) in the sonication buffer, and duration of sonication to achieve the desired fragmentation pattern.

In recent years, long noncoding RNAs (lncRNAs) have garnered considerable attention as a novel and critical layer of biological regulation. Our knowledge regarding the roles and underlying mechanisms of lncRNAs in various diseases, including DKD, continues to evolve. Similarly, microRNAs (miRNAs), which are small noncoding RNAs, have been recognized as crucial contributors to cellular processes and disease pathogenesis. Emerging studies have highlighted the complex interactions between lncRNAs and miRNAs, particularly in the context of DKD, underscoring their importance in complex human diseases. Renal intrinsic cell damage is an important cause of inducing DKD. Persistent high glucose stimulation leads to remodeling of renal intrinsic cells and a cascade of pathological changes. This article aims to review recent literature on the lncRNAs-mediated regulation of miRNAs affecting renal intrinsic cells in DKD and to propose novel molecular-level therapeutic strategies for DKD. Through in-depth investigation of this dynamic molecular interaction, we can gain a profound understanding of the potential mechanisms underlying diabetic nephropathy, potentially identifying new targets for therapeutic intervention and paving the way for personalized and effective treatments.","PeriodicalId":93981,"journal":{"name":"DNA and cell biology","volume":" ","pages":"304-324"},"PeriodicalIF":0.0,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143675119","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

During lung homeostasis, they are involved in the clearance of inhaled particles, cellular remnants, and even participate in metabolic processes. In disease states, lung macrophages transition from the inflammatory M1 phenotype to the anti-inflammatory M2 phenotype.

Defects in gene regulation can lead to serious errors in genetic transmission, such as increased instability of chromosomes, thereby increasing susceptibility to cancer and promoting its development. The maintenance of chromosome stability depends on several mechanisms, such as efficient DNA repair, proper sister chromatid separation, and timely cytokinesis. The serine/threonine kinase Plk1 is a key molecule in maintaining chromosome stability, participating in multiple stages of precise regulation during mitosis, including promoting entry into mitosis, facilitating centrosome maturation and bipolar spindle formation, promoting sister chromatid separation, and facilitating cytokinesis. Several proteins can regulate the kinase activity of Plk1 through protein-protein interactions, coordinating the genetic stability of the cell, including the kinases Aurora A, c-Abl, and Chk1 as well as the phosphatase phosphatase and tension homolog (PTEN). PTEN has been described as an essential regulator of Plk1 for dephosphorylation and chromosomal stability during cell division, and Plk1 may directly interact with and phosphorylate PTEN at centromeres. Here, we review the bidirectional interplay between Plk1 and PTEN and how it contributes to genomic stability during mitosis.","PeriodicalId":93981,"journal":{"name":"DNA and cell biology","volume":" ","pages":"263-273"},"PeriodicalIF":0.0,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143675056","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The stomatal apparatus also consisted of two crescent-shaped guard cells, forming a spindle shape with thickened \"T-shaped\" ends. Furthermore, the outer stomatal arches had smooth surfaces, while the inner ones were shallowly undulated. Finally, subsidiary cells were covered by a shallowly undulated epidermal stratum corneum that was composed of three layers. Their pollen grains exhibited a prolate spherical shape. Based on pollen morphology, the Babu Tea was therefore classified within Sect. Theopsis Coh. St., Camellia.

While mucins are believed to play a role in the pathogenesis and pathophysiology of airway diseases, no genetic studies on mucin genes have been conducted to date. We initially analyzed a genome-wide association dataset of 608 asthmatics, focusing on mucin gene polymorphisms. Subsequently, we conducted fine genotyping of the MUC13 gene in a separate cohort of 704 bronchial asthma patients monitored for over a year. Using generalized linear models and multiple logistic regression analyses, we evaluated the genetic associations of single nucleotide polymorphisms (SNPs) with the frequency of annual exacerbations and the likelihood of frequent exacerbations. Among 105 SNPs in 14 mucin genes analyzed, rs6765247 in MUC13 showed the most significant association with annual asthma exacerbation frequency. Fine genotyping revealed that individuals homozygous for the minor allele of rs6765247T>G had significantly more annual exacerbations compared to those with the common allele (mean ± SD; 0.94 ± 1.73 vs. 0.43 ± 1.02 and 0.35 ± 0.79, p = 0.001). The frequency of minor allele homozygotes was 3.2 times higher in frequent exacerbators than in nonfrequent exacerbators. The associations were particularly significant in smokers (interaction p = 0.009). These findings indicate that MUC13 is important in exacerbating asthma due to smoking and could be used as a marker to predict frequent exacerbations in smokers.","PeriodicalId":93981,"journal":{"name":"DNA and cell biology","volume":" ","pages":"294-303"},"PeriodicalIF":0.0,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144028764","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
