Abstract: A composition comprises a glucocorticoid receptor agonist and a compound which decreases levels of active human serine/threonine protein phosphatase 5 protein in cells. The glucocorticoid receptor agonist is dexamethasone and the compound is an antisense oligonucleotide of about 8 to 50 nucleotides in length which is targeted to a nucleic acid encoding human serine/threonine protein phosphatase 5. The composition is useful in a method of enhancing glucocorticoid activity, and in a method of enhancing the inhibition of hyperproliferation of cells where the inhibition is by contacting the cells with a compound which decreases levels of active human serine/threonine protein phosphatase 5 protein in cells. The compound is thus useful to enhance glucocorticoid therapy and to enhance inhibition of hyperproliferation relating to PP5.
