Cancer proteomics is a branch of proteomics that studies cancer cells' proteins. It involves the identification and quantification of proteins within a biological sample. Cancer proteomics research uses various methods, including mass spectrometry, microarrays, bioinformatics, and gene expression profiling, to study the structure and function of different proteins involved in cancer. By combining proteomic and genomic data, researchers comprehensively understand cancer and potential treatment targets. This book offers insight into this rapidly evolving field of cancer research for researchers, clinicians, and students interested in cancer proteomics.
