Abstract
- Diabetic cardiovascular complication is a common systemic disease with high morbidity and mortality worldwide. We hypothesise that exosomes derived from human umbilical cord mesenchymal stem cells (hUCMSCs-exos) can rescue these disorders and alleviate vascular remodeling in diabetes. Morphological, non-targeted metabolomics and 4D label-free proteomics techniques were used to analyze the aortas of db/m mice as normal control group (NCA), saline treated db/db mice (DMA), and hUCMSCs-exos treated db/db mice (DMTA), and to clarify the molecular mechanism of the protection of hUCMSCs-exos in vascular remodeling from a new point of view. The results showed that 74 metabolites were changed significantly in diabetic aortas, of which 15 were almost restored by hUCMSCs-exos. In proteomics, 30 potential targets such as Stromal cell-derived factor 2-like protein 1, Leukemia inhibitory factor receptor, Peroxisomal membrane protein and E3 ubiquitin-protein ligase MYCBP2 were detected. Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway-based analysis showed that Central carbon metabolism in cancer and Galactose metabolism pathway were up-regulated to near normal by hUCMSCs-exos in metabolomics, with janus associated kinase-signal transducer and activator of transcription (JAK-STAT) pathway displayed in proteomics. According to bioinformatics and integrated analysis, these targeted molecules of hUCMSCs-exos to attenuate the vascular remodeling were mainly associated with regulation of energy metabolism, oxidative stress, inflammation, and cellular communications. This study provided a reference for the therapy of diabetes-induced cardiovascular complications. [Display omitted] • Diabetic cardiovascular complication is a common systemic disease worldwide. • Metabolomics and proteomics are used to identify potential markers and mechanisms. • Exosomes from mesenchymal stem cells alleviate aortic remodeling in diabetic mice. • JAK-STAT signaling is enriched by proteomics in exosomes interference.
