Transcriptomic and Proteomic Profiling of Human Mesenchymal Stem Cell Derived from Umbilical Cord in the Study of Preterm Birth


ABSTRACT: Mesenchymal stem cells (MSCs) hold great therapeutic potential in morbidities associated with preterm birth. However, the molecular expressions of hMSCs in preterm birth infants have not been systematically evaluated. In this study, we presented the dual-omics analyses of umbilical cord (UC) derived hMSCs to identify the dysregulated cellular functions. Materials and methods: The UC-MSCs were collected from 10 full-term and 8 preterm birth infants for transcriptomics and proteomics analyses by using microarray and iTRAQ-based proteome profiling. The integrative analysis of dual-omics data discovered 5,615 commonly identified genes/proteins of which 29 genes/proteins showed consistent up- or down-regulation in preterm birth. The Gene Ontology analysis revealed that the biological processes of mitochondrial translation and cellular response to oxidative stress were mainly enriched in 290 differential expression proteins (DEPs) while the 421 differential expression genes (DEGs) were majorly involved in secondary alcohol metabolic process, cellular response to stress, and mitotic cell cycle in preterm birth. Besides, we identified a 13-protein module involving CUL2 and CUL3, which plays an important role in cullin-RING-based ubiquitin ligase complex, as potential mechanism for preterm birth. The dual-omics data not only provided new insights to the molecular mechanism but also to identify panel of candidate markers associated with preterm birth.
