Abstract: In alternative embodiments, provided are compositions and methods for treating, enhancing the drug sensitivity of, and preventing the formation of cancer stems cells, including preventing or slowing the development or generation of a beta-3 (?3)-expressing, or integrin ?3 (ITG-B3)-expressing cancer or tumor cells. In alternative embodiments, provided are methods using histone acetyl transferase inhibitors and/or histone methyl transferase inhibitors to determine therapeutic values in cancer cells that induce an integrin ?3 (ITGB3) polypeptide expression. In alternative embodiments, provided are kits, blister packages, lidded blisters or a blister card or packet, clamshells, trays or shrink wraps, comprising at least one compound, composition or formulation used to practice a method as provided herein, and at least one Growth Factor Inhibitor.

Abstract: In alternative embodiments, provided are products of manufacture, such as assays, chimeric nucleic acids and nucleic acid constructs, recombinant cells, and methods, comprising use of beta3-integrin (ITGB3) promoters operatively linked to a reporter, for drug screening, and in particular, screening for agents that inhibit cancer cell survival and metastasis. In alternative embodiments, compositions and methods as provided herein also can be used to identifying novel pathways that lead to acquired resistance, stemness, and anchorage independent growth; and characterizing distinct populations of cancer cells within a tumor microenvironment.

Abstract: Provided are compositions, including kits, and methods comprising use of a biomarker ?3 integrin, including the ?v?3 integrin, for detecting circulating tumor cells (CTCs), tumor stem cells, extracellular vesicles (EV), including exosomes and microvesicles, that are released by CTCs or cancer cells, as well as the tumor from which the CTCs or EVs derive, and to make a patient prognosis, and to assess tumor progression, and drug resistance (for example, resistance to tyrosine kinase inhibitors), e.g., for several cancers including: breast, colon, lung and pancreatic cancers. In alternative embodiments, a patient fluid sample, e.g., a blood, serum, urine, CSF or other sample, is taken and used to detect cancer stem cells, EVs- and/or CTCs-comprising ?3 integrin and/or a ?v?3 integrin. Provided are compositions, including kits, and methods and uses of the biomarker ?3 integrin for anti-cancer drug design.

Abstract: In alternative embodiments, the invention provides compositions and methods for overcoming or diminishing or preventing Growth Factor Inhibitor resistance in a cell, or, a method for increasing the growth-inhibiting effectiveness of a Growth Factor inhibitor on a cell, or, a method for re-sensitizing a cell to a Growth Factor Inhibitor, comprising for example, administration of a combination of a TBK1 inhibitor and an RTK inhibitor. In alternative embodiments, the cell is a tumor cell, a cancer cell or a dysfunctional cell.

Abstract: In alternative embodiments, the invention provides compositions and methods for identifying individuals that would be responsive to a treatment comprising (including) blocking activation of integrin polypeptide alphav-beta3 (or ?v-?3), or blocking the interaction of a ligand with integrin polypeptide alphav-beta3 (or ?v-?3). The invention provides compositions and methods for determining the effectiveness of such a treatment and can contribute to a prognosis for the patient.
