Abstract: Bistable devices are constructed using a polynucleotide platform for sensing molecular events such as binding or conformational changes of target molecules. Uses include measuring target concentration, measuring effects of environmental conditions on the target, or screening a library for molecules that bind the target or modulate its biological function. Devices include three regions: a top lid, bottom lid, and flexible linker or hinge between them. A device has an open configuration in which the top and bottom lid are separated, and a closed configuration in which they are bound close together. Binding domains or variations of the target molecule are fixed to a device so that when the molecular event occurs, the device switches from open to closed, or vice versa, which generates a signal. Devices may carry DNA tags to enable separation of open and closed devices and barcoding for multiplexed detection.

Abstract: Phosphatidylinositol 3-kinases (PI3Ks) are known to be important regulators of signaling pathways. To determine whether PI3Ks are genetically altered in cancers, we analyzed the sequences of the PI3K gene family and discovered that one family member, PIK3CA, is frequently mutated in cancers of the colon and other organs. The majority of mutations clustered near two positions within the PI3K helical or kinase domains. PIK3CA represents one of the most highly mutated oncogenes yet identified in human cancers and is useful as a diagnostic and therapeutic target.
