The traditional single-omics strategy for identifying seed size-related genes has the disadvantage of low accuracy, limiting its potential application in molecular breeding.<h3>Objectives</h3>This study aimed to integrate multi-omics approaches to identify key genes and pathways regulating cotton seed size.<h3>Methods</h3>We employed 413 accessions of seeds from natural cotton populations to quantitatively obtain seed size-related phenotypes (length, width, area, roundness, perimeter, length-to-width ratio, and seed index) using phenomics technology. Dimensionality reduction was applied to seven phenotypic datasets to identify elements that can simultaneously map phenotypic traits. These were then combined with genomic data for genome-wide association studies (GWAS) to identify candidate genes. Representative accessions were screened by k-means clustering to construct differential gene expression profiles at different developmental stages, and a hub gene set was determined by WGCNA. Genes in QTL from GWAS and hub genes from WGCNA are co-localized to identify key genes, and gene functions are verified through genetic material construction and metabolomics analysis.<h3>Results</h3>The co-localization results from GWAS and transcriptomics efficiently and precisely identified a novel gene, <em>GhCSS10</em>. Constructed RNAi and overexpression transgenic lines confirmed their positive regulation of seed size. Metabolomics further demonstrated that variations in seed size are closely associated with metabolic processes, including cell energy activation, cell expansion, carbohydrate deposition, and seed filling.<h3>Conclusion</h3>The multi-omics integration strategy developed in this study effectively identifies key genes and metabolic pathways regulating cotton seed size. It provides a novel perspective for elucidating the molecular basis of cotton seed development and offers highly valuable targets for genetic improvement in cotton.","PeriodicalId":14952,"journal":{"name":"Journal of Advanced Research","volume":"10 1","pages":""},"PeriodicalIF":10.7,"publicationDate":"2026-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147695925","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We report that endogenous H<sub>2</sub> facilitates the floral transition in Arabidopsis.<h3>Methods</h3>The Nuclear Architecture Related 1 (NAR1) gene of <em>Arabidopsis</em> was prokaryotic expressed and purified, and its H<sub>2</sub>-synthesizing activity was subsequently detected. Furthermore, mutation experiments were used to investigate the catalytic roles of conserved sequences and Cys sites. Biochemistry and molecular approaches were employed to investigate the role of H<sub>2</sub> in regulating floral transition.<h3>Results</h3>Similar to [Fe-Fe] hydrogenase (HYD1) from <em>Chlamydomonas reinhardtii</em>, NAR1 protein is a H<sub>2</sub>-synthesizing enzyme in <em>Arabidopsis thaliana</em>. Protein mutation experiments in vitro show that four Cys residues are important for the inducible catalyzing activity upon hypoxia. Accordingly, NAR1-dependent circadian-rhythmic H<sub>2</sub> was observed under light/dark cycles, which was accompanied with contrasting changes in nitric oxide (NO) signal. Knockdown of <em>NAR1</em> by CRISPR or RNAi reduced H<sub>2</sub> production and delayed flowering. Whereas, exogenous H<sub>2</sub> supply and overexpressing <em>NAR1</em> or <em>CrHYD1</em> promoted early flowering. These early flowering phenotypes were aggravated by the removal of endogenous NO, but abolished by NO addition. Since the mutant (<em>mms19</em>) defective in Fe-S cluster assembly function displays early flowering regardless of H<sub>2</sub> addition, we further deduce that NAR1 control of early flowering is largely achieved by H<sub>2</sub>.<h3>Conclusion</h3>Biochemical and genetic evidences show that NAR1-driven floral transition is functionally linked to the modulation of circadian oscillators via NO signaling. Since H<sub>2</sub> production is modulated by circadian rhythms and constitutively produced, it may integrate external and internal cues into floral transition, and the modulation of its production might be a promising strategy for crop breeding cultivation.","PeriodicalId":14952,"journal":{"name":"Journal of Advanced Research","volume":"70 1","pages":""},"PeriodicalIF":10.7,"publicationDate":"2026-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147708668","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Respiratory tract tumors remain a leading cause of global cancer-related deaths due to their high invasiveness and late-stage diagnosis. With the rapid development of high-throughput sequencing technology, the complex associations between microbial communities and respiratory tract tumors have been gradually uncovered. In lung cancer, distinct microbiota-related signatures, including tissue-specific and microbiota-derived ones have been identified, showing variations across cancer subtypes, anatomical sample sources, and patient demographics. These findings collectively lay the foundation for in-depth investigations into the interplay between the microbiome and respiratory tract tumors.<h3>Aim of review</h3>This review aims to systematically synthesize the current understanding of the commensal microbiome across respiratory tract tumors, primarily taking lung cancer as the main example, with systematic extensions to other respiratory tract malignancies, including laryngeal carcinoma and nasopharyngeal carcinoma, focusing on clarifying the ecological characteristics of microorganisms, elucidating the mechanistic links between the microbiome and tumorigenesis as well as progression, and summarizing the translational value of the microbiome in clinical practice, including applications in diagnostics, therapeutics, and prognostic evaluation.<h3>Key scientific concepts of review</h3>Emerging evidence highlights that the microbiome contributes to the initiation of respiratory tract tumors through multiple pathways: dysbiosis-induced chronic inflammation, immune system dysregulation, and metabolite-mediated epigenetic or functional alterations. Beyond tumorigenesis, the microbiome also plays a vital role in modulating the efficacy of cancer treatments, particularly conventional therapies and immunotherapies. Additionally, the microbiome provides novel opportunities for the development of diagnostic biomarkers and microbiome-targeted intervention strategies. Its prognostic potential in predicting recurrence, metastasis, and survival is increasingly recognized. These core scientific concepts collectively constitute the theoretical framework for exploring the microbiome’s role in respiratory tract tumor research and clinical translation.","PeriodicalId":14952,"journal":{"name":"Journal of Advanced Research","volume":"32 1","pages":""},"PeriodicalIF":10.7,"publicationDate":"2026-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147696143","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nevertheless, whether PF4 participates in the development of depression has yet to be determined.<h3>Objectives</h3>The aim of this study was to investigate the role and the underlying mechanisms of PF4 in the pathophysiology of depression.<h3>Methods</h3>Mouse models of depression were established using chronic social defeat stress (CSDS) and lipopolysaccharide (LPS) paradigms. Plasma levels of PF4 and inflammatory cytokines were quantified by enzyme-linked immunosorbent assay (ELISA). A battery of behavioral tests were conducted to evaluate the effects of systemic and intra-nucleus accumbens (NAc) administration of PF4 siRNA or PF4 on depressive-like behaviors. RNA sequencing (RNA-seq) for transcriptomic analysis and immunofluorescence staining were performed to assess neuroinflammatory status and microglial activation.<h3>Results</h3>Plasma PF4 was significantly reduced in patients with major depression. Similarly, CSDS mice exhibited decreased PF4 levels in both plasma and the NAc. Systemic PF4 administration produced an antidepressant-like effect in naive mice and rescued depressive-like behaviors in both CSDS and LPS-treated mice. In CSDS mice, intravenous administration of PF4 suppressed peripheral inflammatory response and increased PF4 levels in the NAc. Knockdown of PF4 in the NAc induced depressive-like behaviors in mice and markedly elevated inflammatory levels in this region. Correspondingly, infusion of PF4 into the NAc mitigated neuroinflammation, inhibited microglial activation, and alleviated depressive-like behaviors in CSDS mice. RNA-seq analysis also confirmed the suppressive effect of PF4 on neuroinflammatory pathways in the NAc.<h3>Conclusion</h3>Our findings demonstrate that PF4 exert an antidepressant effect, at least in part, by suppressing neuroinflammatory responses within the NAc. This work identifies PF4 as a novel and promising therapeutic target for the treatment of major depression.","PeriodicalId":14952,"journal":{"name":"Journal of Advanced Research","volume":"22 1","pages":""},"PeriodicalIF":10.7,"publicationDate":"2026-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147695892","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
