摘要
Background: Salvianolic Acid B (SalB) has been proven to delay the progression of atherosclerosis. The therapeutic mechanisms of this compound are unclear. A novel class of short non-coding RNAs, pre-transfer RNA and mature transfer RNA (tsncRNAs) may regulate gene expression. TsncRNAs-sequencing revealed novel therapeutic targets for SalB. This is the first study focusing on tsncRNAs to treat atherosclerosis using SalB. Purpose: To explore the potential mechanism of SalB treating atherosclerosis through tsncRNAs. Methods: Five groups of mice were created at random: control group (CON), atherosclerosis model group (MOD), SalB with high dose-treated group (SABH), SalB with low dose-treated group (SABL), and Simvastatin-treated group (ST). Aortic sinus plaque, body weight and inflammatory cytokines were evaluated. The Illumina NextSeq equipment was used to do expression profiling of tsncRNAs from serum. The targets of tsncRNAs were then predicted using tRNAscan and TargetScan. The KEGG pathway and GO analysis were utilized to forecast the bioinformatics analysis. Potential tsncRNAs and associated mRNAs were validated using quantitative real-time PCR. Results: tRF-Glu-CTC-014 and tRF-Gly-GCC-074 were markedly increased by SalB with high dose treatment and validated with quantitative real-time PCR. Two mRNAs SRF and Arrb related to tRF-Glu-CTC-014 changed consistently. GO analysis revealed that the altered target genes of the selected tsncRNAs were most enriched in protein binding and cellular process. Moreover, KEGG pathway analysis demonstrated that altered target genes of tsncRNAs were most enriched in MAPK signaling pathway. Conclusion: SalB can promote the expression of tRF-Glu-CTC-014 to treat atherosclerosis.
