Natural compounds, particularly those derived from marine sources, present a promising avenue for developing novel therapeutics. In this study, we investigated the potential of <em>Chlorella vulgaris</em>, a unicellular green alga with a rich profile of bioactive compounds, as a source of anti-inflammatory agents. Through <em>in silico</em> molecular docking and dynamics simulations, we identified compounds C8 and C4 as potent inhibitors of COX-1 and NIK, key targets in inflammatory pathways. These compounds demonstrated significantly stronger binding affinities than standard inhibitors MXM and OWC. For COX-1, C8 and C4 showed binding affinities of −8.625 and −4.359 kcal/mol, respectively, compared to −3.454 kcal/mol for MXM. Similarly, for NIK, the binding affinities were −6.798 and −3.789 kcal/mol for C8 and C4, respectively, compared to −2.628 kcal/mol for OWC. Molecular dynamics simulations further demonstrated that C8 and C4 formed stable interactions, including hydrogen bonds and hydrophobic contacts, with key residues in the active sites of COX-1 and NIK, suggesting a potential for sustained inhibitory activity. These findings highlight the therapeutic potential of <em>C. vulgaris</em> derived compounds for the treatment of inflammatory conditions. Although further in vitro and in vivo studies are necessary to fully elucidate their efficacy and safety, these results provide a promising foundation for the development of novel, naturally sourced anti-inflammatory therapies.</div></div>","PeriodicalId":53463,"journal":{"name":"Journal of Genetic Engineering and Biotechnology","volume":"23 3","pages":"Article 100531"},"PeriodicalIF":3.5,"publicationDate":"2025-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144513573","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}

Using an integrative bioinformatics approach, we analyzed GEO datasets (GSE3365 and GSE9128) to identify shared genetic pathways between CD and ICM. Through differential expression analysis, we identified 60 common differentially expressed genes (CDEGs). Functional enrichment analysis revealed enrichment in inflammatory pathways, including NF-κB and TNF-α signaling, highlighting their role in disease pathogenesis. We conducted microRNA (miRNA), transcription factor (TF), and protein–protein interaction (PPI) analyses to uncover regulatory networks. Notably, hsa-miR-98-5p emerged as a key miRNA, while RELA and NFKB1 were identified as prominent TFs interacting with CDEGs. Six hub genes—IL1B, CXCL8, CXCL2, TLR2, FCGR1A, and FCGR2A—were pinpointed, demonstrating high diagnostic potential via receiver operating characteristic (ROC) analysis. To advance diagnostic precision, we developed AutoClass, a deep learning framework that leverages hub gene regulatory networks to classify CD patients with approximately 95 % accuracy. These hub genes and regulators likely drive neutrophil-mediated inflammation, offering insights into the molecular interplay between CD and ICM. Our findings suggest that the identified CDEGs, miRNAs, and TFs hold promise as therapeutic targets and biomarkers, paving the way for precision medicine approaches in managing CD and its cardiovascular complications.

The disease has intensified in Asian countries such as Bangladesh, India, Myanmar, and Thailand, with regular outbreaks since 2015, partly due to the lack of effective vaccines or treatments against this ferocious virus. Nonstructural (NS) genes of Dengue virus (DENV) are believed to play vital role in viral replication. Targeting the NS genes of existing serotypes of DENV, we aimed to design a potential small interfering RNA (siRNA) that has the capability to silence the NS genes hence, provide a ground strategy for antiviral therapeutics. In this investigation, a comprehensive computational approach encompassing data collection from NCBI database, GC content analysis, conservation prediction across all DENV serotypes, mRNA-siRNA duplex thermodynamic assessment, siRNA efficacy evaluation, molecular modeling and structural refinement, molecular docking were performed. These analyses anticipated three efficient siRNAs (S2, S3 and S11) that could have the capability to silence all the NS protein-coding genes employed by the DENV. Based on additional analysis including molecular dynamic (MD) simulation, principal component analysis (PCA) and free energy landscape (FEL), two siRNAs (S2 and S11) were recommended as potential therapeutics that could effectively degrade viral NS protein-coding genes through the RNAi pathway. However, S2 (Guide: 5′-UGUUUUUCGCCUUUUUCCGUU-3′ and Passenger: 5′- CGGAAAAAGGCGAAAAACACG-3′) molecule is supposed to be appeared the most promising siRNA compared to S11.
