Their efficient utilisation depends on understanding their history and genetic relationships. The current study investigates the phylogenetic relationships of barley landraces from Algeria, varieties from the Near and Middle East, traditional landraces, and modern cultivars from Europe. Using a core set of 33 varieties, including the wild ancestor <i>Hordeum spontaneum</i> from Armenia, genetic diversity was analysed with Random Amplified Polymorphic DNA (RAPD) and Simple Sequence Repeat (SSR) markers spanning all barley chromosomes. Based on the SSR-based phylogeny, the Algerian varieties are well clustered with those from the Near East, while distinct from the European varieties. The findings from RAPD markers partially support these results. Using exclusively traditional landraces, where a region of origin can be defined, the SSR markers are analysed separately for each chromosome individually, and the resulting clades are represented by the respective region of origin. This strategy resolves qualitative differences in geographic resolution, depending on the chromosome. While marker HvB23D (chromosome 4) separated the wild <i>H. spontaneum</i> from all domesticated genotypes, markers Bmag19 and Hv13GIII (chromosome 3) reveal four distinct geographic clusters (Maghreb, Near and Middle East, West Europe, Central Europe). These biogeographic patterns suggest a model, where divergence of domesticated barley due to human activity interacted with introgression of individual chromosomes from wild barley, yielding adaptive diversity. These biogeographic patterns suggest a model in which the divergence of domesticated barley, driven by human activity, interacts with the introgression of chromosomes from wild barley, resulting in the creation of adaptive genetic diversity. Our research advances our knowledge of barley landraces' functional genomics and highlights their potential in molecular breeding, particularly for developing resilient varieties suited to diverse environmental conditions.</p>","PeriodicalId":10839,"journal":{"name":"Current Issues in Molecular Biology","volume":"46 12","pages":"14226-14243"},"PeriodicalIF":2.8,"publicationDate":"2024-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11674917/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142892735","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

C6 ceramide is recognized for its multifaceted anti-cancer properties, yet its specific influence on CMCs remains to be elucidated. Long noncoding RNAs (lncRNAs), now recognized as functional \"dark matter\" in precision oncology, are particularly intriguing, with 44% of canine lncRNAs exhibiting tissue-specific expression. In this study, we performed a thorough analysis of lncRNA expression profiles to uncover the mechanisms behind C6 ceramide's anti-cancer activity in CHMp cells. Our findings reveal that C6 ceramide notably inhibits the proliferation of CHMp cells. RNA sequencing identified 4522 lncRNAs with expression changes following C6 ceramide treatment, of which 2936 were upregulated and 1586 were downregulated. Further investigation into Lnc_025370 showed that it is predominantly nuclear-localized and is significantly downregulated by C6 ceramide treatment. Functional studies discovered that overexpression of Lnc_025370 enhances the growth and metastatic capabilities of CHMp cells, which is associated with an increase in NRG1, and concurrently diminishes the anti-cancer effectiveness of C6 ceramide in vitro. Mouse xenograft models also showed that Lnc_025370 overexpression promotes tumor growth and Ki67 expression. Together, our results suggest that Lnc_025370 acts as a pivotal target mediator of C6 ceramide's anti-cancer effects, facilitating the malignant progression of CHMp cells.</p>","PeriodicalId":10839,"journal":{"name":"Current Issues in Molecular Biology","volume":"46 12","pages":"14190-14203"},"PeriodicalIF":2.8,"publicationDate":"2024-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11674213/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142892259","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
