The present invention describes polynucleotides that have been discovered to correlate to the relative intrinsic sensitivity or resistance of cells, e.g., lung cell lines, to treatment with compounds that interact with and modulate, e.g., inhibit, protein tyrosine kinases, such as, for example, members of the Src family of tyrosine kinases, e.g., Src, Fgr, Fyn, Yes, Blk, Hck, Lck and Lyn, as well as other protein tyrosine kinases, including, Bcr-abl, Jak, PDGFR, c-kit and Ephr. These polynucleotides have been shown, through a weighted voting cross validation program, to have utility in predicting the resistance and sensitivity of lung cell lines to the compounds. The expression level of some polynucleotides is regulated by treatment with a particular protein tyrosine kinase inhibitor compound, thus indicating that these polynucleotides are involved in the protein tyrosine kinase signal transduction pathway, e.g., Src tyrosine kinase. Such polynucleotides, whose expression levels correlate highly with drug sensitivity or resistance and which are modulated by treatment with the compounds, comprise polynucleotide predictor or marker sets useful in methods of predicting drug response, and as prognostic or diagnostic indicators in disease management, particularly in those disease areas, e.g., lung cancer, in which signaling through the protein tyrosine kinase pathway, such as the Src tyrosine kinase pathway, is involved with the disease process.

The use of the induced hepatocytes obtained by the present invention can establish and develop, as general medical treatment, cell transplantation into the liver, artificial livers, and drug response tests, which are the areas that have not been generalized because of the difficulty of procuring hepatocytes.

The disclosed technology describes compositions and methods useful for providing cell based therapy. For example, one embodiment of cell based therapy involves the regeneration of injured tissue and / or promoting wound healing. Certain embodiments provide improved therapeutic compositions using microbubbles by delivering biological progenitor cells to the injured tissues. The administration of the microbubbles is directed by acoustic radiation forces that interact with embodiments of microbubbles comprising an acoustically active gas. As such, a high efficiency of progenitor cell delivery to injured tissue is realized. One advantage of this technique over targeted delivery of pharmaceutical compounds, is that the delivered progenitors cells may be derived from the patient (i.e., personalized therapy), thereby avoiding side effects, allergic reactions, and overall problems associated with refractive drug responses.

A method and system for use in treating a patient receiving an anticoagulant or a substance containing warfarin to optimize therapy and prevent an adverse drug response. This system employs surrogate markers or indicators including blood levels of the anticoagulant to determine the next required dose for a patient. Since the surrogate markers are employed as a percent change in status, virtually any indicator can be used. Surrogate markers could include any measure of the effectiveness of the anticoagulant's action. Given the effectiveness of the anticoagulant's action relative to the surrogate markers, a change in anticoagulant dose is calculated by the system. Conversely, by employing this system, one could determine the expected result of the anticoagulant dose change on the surrogate markers.
