Morphoproteomics and bortezomib/dexamethasone-induced response in relapsed acute lymphoblastic leukemia

"Morphoproteomics" is defined as the identification by immunohistochemistry of the molecular circuitry of various proteins in a tumor by noting their state of activation (translocation and phosphorylation) and correlative expressions. This approach can uncover potential targets, amenable to therapeutic interventions, that are specific for an individual patient's tumor (ie, customized chemotherapy). This communication illustrates the successful application of such an approach in a patient with relapsed acute lymphoblastic leukemia.
