Illumina tRFs & tiRNAs-seq analysis was used to characterize the whole transcriptomes of acute rejection caused by vascularized composite allotransplantation (VCA). tRFs & tiRNAs-seq information for muscle samples with VCA was obtained and compared with similar information for same age- and sex-matched healthy control subjects. The expression of 16 tRFs and tiRNAs, including 5 up-regulated target genes and 11 down-regulated target genes, were significantly different. According to bioinformatics analysis and reverse transcription quantitative polymerase chain reaction, we speculate that tiRNA-1-34-Glu-CTC-1 plays an important role in VCA-induced acute rejection by regulating the CACNA1D gene in the MAPK signaling pathway The findings provide the whole-transcriptome signatures of acute rejection for VCA, allowing further exploration of gene expression patterns/signatures associated with the various clinical symptoms of acute rejection for VCA.
Illumina tRFs 和 tiRNAs-seq 分析用于描述血管化复合组织移植 (VCA) 引起的急性排斥反应的全转录组。获取了 VCA 肌肉样本的 tRFs 和 tiRNAs-seq 信息，并与同年龄和性别匹配的健康对照者的类似信息进行了比较。有 16 种 tRFs 和 tiRNAs 的表达存在显著差异，包括 5 个上调的靶基因和 11 个下调的靶基因。根据生物信息学分析和逆转录定量聚合酶链反应，我们推测 tiRNA-1-34-Glu-CTC-1 通过调节 MAPK 信号通路中的 CACNA1D 基因在 VCA 诱导的急性排斥反应中发挥重要作用。研究结果为 VCA 提供了急性排斥的全转录组特征，进一步探索了与 VCA 各种急性排斥临床症状相关的基因表达模式/特征。
