Protein isoforms could serve as novel non-small cell lung cancer biomarkers or therapeutic targets

Proteomics is the study and analysis of proteins, including their structures, functions, interactions, and modifications within a biological system. Humans have approximately 20,000 genes that produce over a million different protein variants, including an estimated 100,000 protein isoforms. These protein variants comprise the vast complexity of the proteome that has remained largely unexplored.
