Explain how breast cancer diagnosis and treatment has benefited from proteomics and genomic analyses. What will be an ideal response?
ANSWER: Proteomics and gene expression profiles provide information for the diagnosis and treatment
of disease and are becoming a routine part of medical care. Genomic and genetic analyses
have shown that breast cancer is not a single disease, but rather, a collection of diseases that
share the same place in the body. Four different subtypes of breast cancer have been
identified, each with distinct rates of progress and responses to therapy. Proteomic analysis
has shown that each subtype has a characteristic protein signature. These proteins are
biomarkers that are now used for diagnosis and the design of the most effective therapies for
each subtype
