The objective of this study was to elucidate the proteomic and transcriptomic alterations within the cartilage in Kashin-Beck disease (KBD) compared to a normal control. We conducted a comparison of the expression profiles of proteins, mRNAs, and lncRNAs via data-independent acquisition (DIA) proteomics and transcriptome sequencing in six KBD individuals and six normal individuals. To facilitate the functional annotation enrichment analysis of the differentially expressed (DE) proteins, DE mRNAs, and DE lncRNAs, we employed bioinformatic analysis utilizing Gene Ontology (GO) and the Kyoto Encyclopedia of Genes and Genomes (KEGG). Additionally, we conducted integration analysis of multi-omics datasets using mixOmics. We revealed a distinct proteomic signature, highlighting 53 DE proteins, with notable alterations in the pathways related to tryptophan metabolism and microbial metabolism. Additionally, we identified 160 DE mRNAs, with the functional enrichment analysis uncovering pathways related to RNA metabolism and protein splicing. Furthermore, our analysis of the lncRNAs demonstrated biological processes involved in protein metabolism and cellular nitrogen compound metabolic processes. The integrative analysis uncovered significant correlations, including the positive correlation between superoxide dismutase 1 () and mitochondrial import receptor subunit TOM6 homolog (TOMM6), and the negative correlation between C-X9-C motif-containing 1 () and succinate-CoA ligase [GDP-forming] subunit beta, mitochondrial (SUCLG2). Our results provide novel insights into the molecular mechanisms underlying KBD.
本研究的目的是阐明与正常对照相比,大骨节病(KBD)软骨内的蛋白质组和转录组变化。我们通过数据非依赖采集(DIA)蛋白质组学和转录组测序,对6例KBD患者和6例正常个体的蛋白质、mRNA和lncRNA表达谱进行了比较。为便于对差异表达(DE)蛋白、DE mRNA和DE lncRNA进行功能注释富集分析,我们利用基因本体论(GO)和京都基因与基因组百科全书(KEGG)进行了生物信息学分析。此外,我们使用mixOmics对多组学数据集进行了整合分析。我们揭示了一种独特的蛋白质组特征,突出了53种DE蛋白,色氨酸代谢和微生物代谢相关途径有显著变化。此外,我们鉴定出160种DE mRNA,功能富集分析揭示了与RNA代谢和蛋白质剪接相关的途径。此外,我们对lncRNA的分析表明其参与蛋白质代谢和细胞氮化合物代谢过程。整合分析发现了显著的相关性,包括超氧化物歧化酶1()与线粒体导入受体亚基TOM6同源物(TOMM6)之间的正相关,以及含C-X9-C基序的1()与线粒体琥珀酰辅酶A连接酶[GDP形成]亚基β(SUCLG2)之间的负相关。我们的结果为KBD潜在的分子机制提供了新的见解。
