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. In alternative embodiments, the invention provides compositions and methods for determining: whether an individual or a patient would benefit from or respond to administration of a Growth Factor Inhibitor, or, which individuals or patients would benefit from a combinatorial approach comprising administration of a combination of: at least one growth factor and at least one compound, composition or formulation used to practice a method of the invention, such as an NFKB inhibitor, such as a lenalidomide or a REVIAMID™, or IKK inhibitor or an inhibitor of Galectin-3.
