Introduction: Mitosis is fundamental to the life of eukaryotic multicellular organisms. Its medical significance is demonstrated by the fact that its dysregulation is a hallmark of cancer. Due to its importance, mitosis is a widely studied process: a wealth of multi-omics and molecular interaction data is available, yet the system-level integration of these data poses a major challenge.
Aims: We are building a systems-level dynamic network model of mitosis based on time-course multi-omics data, high-resolution 3D confocal imaging, and data from external databases (e.g., MitoCheck). Initially, our aims were to identify differentially abundant proteins (DAPs) and differentially expressed genes (DEGs) in the time-course proteomics and transcriptomics data from HeLa cells across the phases of mitosis.
Method: The time-course proteomics data from 40 subsections of mitosis, generated by the combination of the “Regression Plane” concept with Computer-Aided Microscopy Isolation (CAMI) and the “Deep Visual Proteomics” method, and a pilot transcriptomics dataset from the metaphase and telophase were analysed with Limma (Linear Models for Microarray Data) to identify DAPs and DEGs. The STRING database was used to annotate biological functions.
Results: In the proteomics dataset, we identified 720 DAPs among 4335 analysed protein groups (FDR<0.1), whereas in the transcriptomics dataset, we identified 101 DEGs among 5998 analysed transcripts (FDR<0.1). As expected, these proteins and transcripts were enriched (FDR<0.05) in mitosis-related processes. Concurrently, we observed enrichment in protein translation–related processes.
Conclusion: Crucial quality control steps showed that the available time-course omics data is suitable for use in dynamic modelling. According to the gene set enrichment analysis, we need to consider the regulation of protein translation alongside mitotic signalling in our model.
