About this Research Topic
Some changes are consistently evolving while others are inconsistent and sporadic. In this Research Topic, we want to explore the coordination among physiological regulation at multiple levels, to further the understanding of aging and age-related diseases. With the fast development of omic technologies , it is more affordable and feasible, with a shorter timespan, to conduct omics based studies. Therefore, more human and animal samples can be analysed and changes detected at multiple levels by utilizing more than one omic technique. The functions of the same or different molecules are affected by different levels of regulations to different degrees. The different forms of products expressed by the same gene, i.e., RNA, protein, metabolite, etc., play different roles in the same or different biological processes and signaling pathways. With the invention and practice of new bioinformatic methods and algorithms, different omic studies can be conducted on the same sample and the results from different omics studies can be combined and integrated within the same analysis. The combination and integration of multi-omics, e.g., genomics, transcriptomics, proteomics, metabolomics, lipidomics, etc., provides great opportunities to dissect and compare the molecular regulation of aging at multiple levels,to reveal the coordination among regulatory changes at multiple levels of control.
We welcome high-quality, original research and review articles focused on improving the current knowledge in the aging and age-related diseases field from the aspects of clinics and basic science. Specifically, at least more than one omic technique should be applied in the original research or discussed in the review article. Areas to be covered in this research topic may include, but are not limited to:
• Tracing progression of aging or age-related diseases at different levels with multi-omics
• Comparison of changes in different species or tissues at different levels
• Feedback and crosstalk of different levels of regulations
• New techniques and bioinformatic methods and algorithms to combine and integrate multi-omics
• Machine learning models with multi-omics data
Please Note: Descriptive studies (e.g. gene expression profiles, or transcript, protein, or metabolite levels under particular conditions or in a particular cell type) and studies consisting solely of bioinformatic investigation of publicly available genomic / transcriptomic data do not fall within the scope of the journal unless they are expanded and provide significant biological or mechanistic insight into the process being studied.
