Inflammation, pain and itch are the most common complications of severe EBS. However, pathophysiological mechanisms remain poorly characterised at a molecular level. Recently, RNA N6-methyladenosine (m6A) nucleotide modification has been implicated in several cutaneous physiological processes, including epidermal differentiation, inflammation, adaptive immune responses, host-pathogen interactions, wound healing and tissue repair. Nevertheless, the role of m6A in EBS has yet to be defined. In this pilot study, we investigated the gene expression of key regulators of m6A, such as writers Methyltransferase-like 3 and 4 (METTL3 and METTL14), readers YTH domain-containing proteins (YTHDC1, YTHDC2, YTHDC3) and YTH domain-containing family proteins ( YTHDF1 and YTHDF2) and erasers fat mass and obesity-associated (FTO) and alkB homolog 5 (ALKBH5), as well as total RNA m6A levels in the EB keratinocites cell line (KEB-7) derived from a patient with severe EBS, carrying the KRT14 R125P mutation. NEB-1 cells, derived from a healthy donor, were employed as controls. RNAseq and quantitative RT-PCR demonstrated up-regulation of the writer METTL14, while FTO was down-regulated. Moreover, the total RNA m6A colorimetric assay reported higher levels of m6A in severe EBS cells (KEB-7). Additionally, increased expression of the reader of YTHDC1 suggests a dysregulation of downstream pathways. These findings suggest a potential role for m6A in determining complications in severe EBS; however, its role and effects need to be fully elucidated.</p>","PeriodicalId":8926,"journal":{"name":"Bioscience Reports","volume":"45 7","pages":""},"PeriodicalIF":3.8,"publicationDate":"2025-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144697472","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}

Recent studies suggest that erythrocyte cholesterol content correlates positively with atherosclerotic cardiovascular disease (ASCVD) severity independent of low-density lipoprotein levels, potentially reflecting residual ASCVD risk. However, conventional methods for measuring erythrocyte cholesterol content require labor-intensive lipid extraction procedures, limiting their clinical applicability. In this study, we developed a novel enzymatic assay that enables direct quantification of erythrocyte total cholesterol content using two denaturants to eliminate hemoglobin interference. This simple method demonstrated high accuracy and precision, as confirmed by intra-assay repeatability, between-day precision, linearity, and spike-recovery tests. Using this assay, we determined the erythrocyte cholesterol content per volume (154.8 ± 2.9 mg/dl in men, 155.9 ± 6.9 mg/dl in women) and per cell (139.0 ± 5.2 fg/cell in men, 140.8 ± 5.3 fg/cell in women) (n = 12, healthy subjects). While erythrocyte cholesterol content per volume correlated with the conventional method, the erythrocyte cholesterol content per cell showed no such correlation. Moreover, neither measure was associated with serum lipid levels, suggesting their potential as independent biomarkers for ASCVD. Additionally, we evaluated erythrocyte cholesterol content across different maturation stages and found that older erythrocytes had significantly lower cholesterol content, consistent with mass spectrometry results. These findings further validated the physiological relevance of the proposed method. In conclusion, we successfully established a simple and clinically applicable enzymatic method for measuring erythrocyte cholesterol content, providing novel insights into erythrocyte cholesterol metabolism and its potential role in ASCVD risk assessment.</p>","PeriodicalId":8926,"journal":{"name":"Bioscience Reports","volume":" ","pages":""},"PeriodicalIF":3.8,"publicationDate":"2025-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144367857","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}

Chlortetracycline (CTC), the first tetracycline (TC) antibiotic discovered nearly eight decades ago, contains a chlorine group. This chlorine is installed enzymatically by the flavin adenine dinucleotide (FAD)-dependent halogenase CtcP. CtcP and the FAD reductase CtcQ, which is also encoded in the CTC biosynthetic gene cluster, function as a two-component system. Structural information on CtcP and CtcQ has been lacking. In this study, we determined crystal structures of CtcP from Kitasatospora aureofaciens in a complex with polyethylene glycol and sulfate ions and in a complex with FAD, and a crystal structure of CtcQ in a complex with FAD and NAD. The structures of CtcP revealed a close similarity of this enzyme to the phenolic halogenase PltM, despite a large difference in the sizes of their respective substrates, presumably TC and phloroglucinol. The CtcP structure showed a conserved dimeric organization also found in PltM crystals. We showed that dimerization of CtcP is allosterically influenced by a distant C-terminal helical hairpin. A closed substrate-binding cavity of CtcP suggested that conformational changes were required to allow a substrate, likely not TC, to bind CtcP. We demonstrated that CtcP and CtcQ weakly bound each other. The dimeric structures of CtcP and CtcQ prompted us to propose approximate models of a 2:2/CtcP:CtcQ complex, where FAD(H2) would shuttle between the two enzymes for chlorination and reduction.</p>","PeriodicalId":8926,"journal":{"name":"Bioscience Reports","volume":" ","pages":""},"PeriodicalIF":3.8,"publicationDate":"2025-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144473923","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}

We here investigate the incidence of AAA at different ages or different doses of Ang II in C57BL/6J mice. There was no AAA formation at a concentration of 1.44 mg/kg/day or 2.16 mg/kg/day at the age of 14 weeks.

Using single-cell RNA sequencing, we found that increased clusters of monocytes and neutrophils, macrophages, T cells, and B cells were the typical changes in AAA. A special cluster transformed from endothelial cells (malignant ECs) was identified, in which genesinvolved in lipid metabolism, including Cd36, Lpl, Gpihbp1, Fabp4, and Pparg, were highly expressed. Mice receiving Ang II treatment without AAA development showed increased fibroblasts, which may prevent the occurrence of AAA. Through cell-cell interaction analysis, we found that the Cxcl12-Cxcr4/Ackr3 axis, which functions in inflammatory ligand- receptor binding, may play a role in AAA formation. Our results reveal that specific cell clusters may contribute to the progression or prevention of AAA formation.
