β-Asarone Inhibits Carboplatin Resistance in Retinoblastoma Cells Through the UCA1/miR-206/NRP1 Axis.
Retinoblastoma (RB) is an aggressive form of eye cancer. β-Asarone is a bioactive component isolated from the medicinal plant Acorus tatarinowii Schott and has anticancer effects on various human cancers. However, reports regarding the role of β-Asarone in RB remain limited. Our study investigates the mechanisms of β-Asarone in regulating drug resistance in RB, providing a theoretical foundation for RB treatment. A carboplatin-resistant RB cell line was established and treated with β-Asarone, followed by overexpression of long non-coding RNA (lncRNA) urothelial carcinoma-associated 1 (UCA1). The half-maximal inhibitory concentration and cell apoptosis were determined. The levels of lncRNA UCA1/miR-206/neuropilin 1 (NRP1) were measured. The subcellular localization of lncRNA UCA1 was examined. The binding relationships between lncRNA UCA1 and microRNA (miR)-206, and between miR-206 and NRP1 were analyzed. NRP1 expression was analyzed by Western blot assay. We found that β-Asarone downregulated lncRNA UCA1 expression in carboplatin-resistant RB cells. Overexpression of lncRNA UCA1 reversed the inhibitory effect of β-Asarone on cell drug resistance and cell proliferation and reduced apoptosis. LncRNA UCA1 functioned as a sponge for miR-206, which suppressed NRP1 expression. Inhibition of miR-206 or overexpression of NRP1 could partially reverse the suppressive effect of β-Asarone on RB cell drug resistance. In conclusion, β-Asarone suppresses RB cell drug resistance through the lncRNA UCA1/miR-206/NRP1 axis.
期刊介绍：
Biochemical Genetics welcomes original manuscripts that address and test clear scientific hypotheses, are directed to a broad scientific audience, and clearly contribute to the advancement of the field through the use of sound sampling or experimental design, reliable analytical methodologies and robust statistical analyses.
Although studies focusing on particular regions and target organisms are welcome, it is not the journal’s goal to publish essentially descriptive studies that provide results with narrow applicability, or are based on very small samples or pseudoreplication.
Rather, Biochemical Genetics welcomes review articles that go beyond summarizing previous publications and create added value through the systematic analysis and critique of the current state of knowledge or by conducting meta-analyses.
Methodological articles are also within the scope of Biological Genetics, particularly when new laboratory techniques or computational approaches are fully described and thoroughly compared with the existing benchmark methods.
Biochemical Genetics welcomes articles on the following topics: Genomics; Proteomics; Population genetics; Phylogenetics; Metagenomics; Microbial genetics; Genetics and evolution of wild and cultivated plants; Animal genetics and evolution; Human genetics and evolution; Genetic disorders; Genetic markers of diseases; Gene technology and therapy; Experimental and analytical methods; Statistical and computational methods.
