A new light of proteomics in cell biology and toxicology

We expect more studies on proteomics-dominated multi- and trans-omics to paint out a dynamic, multi-level, multi-dimensional picture of molecular mechanisms in the single-cell or targeted cell population to elucidate the regulation of gene-gene, gene-protein, and protein-protein interactions, and define proteome-wide strategy of disease-specific biomarker and therapeutic target discovery and development. We hope that the current issue will be the initiation and stimulation of proteome-based investigations to explore molecular mechanisms in cell functioning and responses to drugs.
