Methods of selecting a subject with cancer for treatment with an active agent that modifies pyruvate metabolism, the TCA cycle, or oxidative phosphorylation, as well as methods of treating the subject, determining the efficacy of the treatment, and adjusting the treatment dosage and frequency are provided. Methods of selecting and treating as subject typically include, (a) detecting the level of one or more biomarkers selected from the group consisting of one or more Mitochondrial Pyruvate Carriers (MPC), one or more components of the Pyruvate Dehydrogenase Complex (PDC), or mitochondrial glutamine transporter in diseased or disordered cells obtained from the subject; and (b) selecting the subject for treatment if the subject meets certain criteria and (c) administering the subject an effective amount of an active agent that modifies pyruvate metabolism, the TCA cycle, a related metabolic pathway, or oxidative phosphorylation to treat the disease or disorder.

The present invention relates to the discovery of a method for identifying a treatment regimen for a patient diagnosed with cancer, predicting patient resistance to therapeutic agents and identifying new therapeutic agents, obtaining the specificity profile of a therapeutic agent, a method of designing a scaffold of a therapeutic agent directed against a drug-resistant target, drug scaffolds, and methods of uses thereof to identify drugs to treat diseases such as cancer. Specifically, the present invention relates to the use of an algorithm to identify a mutation in a kinase, determine if the mutation is an activation or resistance mutation and then to suggest an appropriate therapeutic regimen. The invention also relates to the use of a pattern matching algorithm and a crystal structure library to predict the functionality of a gene mutation, predict the specificity of small molecule kinase inhibitors and for the identification of new therapeutic agents.

Provided herein are methods and devices for measuring pH and for amplifying a pH signal to obtain ultrasensitive detection of changes in pH. This is achieved by providing a sensor and a transducer, wherein the sensor transconductance is sensitive to changes in pH and the transducer transconductance is not affected by pH change. The transducer instead compensates for changes in the sensor transconductance arising from pH change. The unique configuration of the sensor and transducer with respect to each other provides substantial increases in a pH amplification factor, thereby providing pH sensing devices with a giant Nernst response and, therefore, effectively increased pH sensitivity.

The present inventors have surprisingly found that a deoxyhypusine synthase (DHPS) gene, which was previously reported to correlate with prostate cancer and cervical cancer, is highly responsive to arteriosclerosis or digestive system cancer, whereby the gene can be used as a desired marker for arteriosclerosis or digestive system cancer. The present invention has been accomplished on the basis of this finding. Specifically, the present invention provides a method for determining arteriosclerosis or digestive system cancer, which method includes detecting expression of a deoxyhypusine synthase gene in a test sample (preferably a blood sample), and determining arteriosclerosis or digestive system cancer of a test subject from which the test sample has been obtained, on the basis of an increase in the gene expression as an index.
