Abstract: The present invention provides methods for reducing the viability of cells that express PI3K?, treating myeloid malignancies, and sensitizing cells, particularly cancer cells that express PI3K? to chemotherapeutic agents. The methods comprise contacting a cell or administering to the subject a PI3K inhibitor that inhibits PI3K? in an isoform-specific manner.

Abstract: Embodiments of the present disclosure relate generally to the treatment of cancer involving activation of the tumor necrosis factor-related apoptosis inducing ligand receptor (TRAILR) pathway. In particular, the present disclosure provides compositions and methods for the identification of genes conferring TRAIL resistance, and the development of rational drug combinations targeting these genes. The therapeutic drug combinations of the present disclosure function synergistically to sensitize cancer cells to TRAIL-resistant cancers.

Abstract: Provided herein are devices, systems, and methods for analysis of objects, such as cells. The devices, systems, and methods organize a plurality of objects in a plurality of partitions by trapping an object in a trap and transferring the object to an adjacent partition. The devices, systems, and methods provide for parallel analysis of a plurality of objects.

Abstract: Compositions containing one or more types of membrane-targeting antimicrobial agents immobilized on a substrate with activity in relevant biological environments, and methods of making and using thereof, are described herein. The antimicrobial agents retain their activity in the presence of blood proteins and/or in vivo due to improved molecular structures which allow for cooperative action of immobilized agents and hydrophilic chemistries which resist non-specific protein adsorption. Suitable molecular structures include branched structures, such as dendrimers and randomly branched polymers. The molecule structures may also include hydrophilic tethers which provide both flexibility and resistance to non-specific protein adsorption. The membrane targeting antimicrobial agent coatings can be applied to a variety of different types of substrates including medical implants such as vascular grafts, orthopedic devices, dialysis access grafts, and catheters; surgical tools, surgical garments; and bandages.

Abstract: A decomposable thin film comprising a plurality of alternating layers of net positive and negative charge. At least a portion of the positive layers, the negative layers, or both, comprise a polyelectrolyte.
