Description: | Results revealed that a total of 41 tRFs/tiRNAs were dysregulated in the AD group compared to the control group. Among them, 12 were upregulated and 29 were downregulated (fold change≥1.5 And p < 0.05). RT-qPCR results revealed that expressions of tRF-1:30-chrM.Met-CAT was significantly upregulated, while that of tRF-54:71-chrM.Trp-TCA and tRF-1:32-chrM.Cys-GCA were notably downregulated; Expression patterns were consistent with the RNA sequencing data. Bioinformatic analysis showed that a variety of related pathways might be involved in the pathogenesis of AD. Functionally, tRF-1:30-chrM.Met-CAT could facilitate proliferation, migration, and phenotype switching in vascular smooth muscle cells (VSMCs), which might serve as a significant regulator in the progression of AD. |
