Protein microarray technology has been successfully used for identifying substrates of purified activated kinases.We used protein microarrays to globally interrogate the effects of PTEN and Clocks Akt activity on the phospho-kinome of in vitro and in vivo glioma models and validated results in clinical pathological specimens.Whole cell lysates extracted from tumor samples can be applied to human kinome chip microarrays to profile the global kinase phosphorylation patterns in a high-throughput manner and identify novel substrates inherent to the tumor cell and the interactions with tumor microenvironment.Our findings identify a novel microarray-based method for assessing intracellular signaling events applicable to ORG SWEET APPLE CIDER human oncogenesis and other pathophysiologic states.
