Dataset Summary
Title | Proteomics identification of regulated proteins during cardyomyocyte differentiation |
Description | The rat cardio-myoblast cell line H9C2 has emerged as an important tool for studying cardiac development and toxicology. We present here a rigorous proteomic analysis that for the first time studied changes of proteins during H9C2 differentiation into cardiomyocyte-like cells over time. Quantitative mass spectrometry followed by gene ontology (GO) enrichment analysis revealed early changes in protein pathways that enable cardiac muscle morphogenesis/contraction and suggested an involvement of proteins relevant to sphingolipid synthesis. This early differentiation was followed by differentiation-induced alterations in cation transport and beta-oxidation at later time points. Applying a two-way ANOVA to study the temporal profile of H9C2 differentiation in further detail revealed eight clusters of co-regulated proteins that could be associated to early, late, continuous and transient up- and downregulation. Subsequent Reactome pathway analysis based on these eight clusters further corroborated and detailed the results of the GO analysis. Specifically, this analysis confirmed proteins related to pathways in muscle contraction as early and transiently upregulated, and proteins relevant to ECM matrix organization as early downregulated, while changes related to cardiac metabolism occurred at later time points. Our results are in line with a ‘function follows form’ model of differentiation, whereby early and transient changes of cellular morphology enable subsequent changes that are relevant for the characteristic physiology of cardiac cells. |
