| abstract |
The present invention relates to methods and compositions designed for treatment, management, or prevention of a hyperproliferative cell disease, particular cancer. The methods of the invention comprise the administration of an effective amount of a composition that targets cells expressing low molecular weight protein tyrosine kinase ('LMW-PTP') in particular using moieties that bind an Eph family receptor tyrosine kinase, such as EphA2 or EphA4, and inhibits or reduces LMW-PTP expression and/or activity. In i one embodiment, the method of the invention comprises administering to a subject a composition comprising an EphA2 or EphA4 targeting moiety attached to a delivery vehicle, and one or more agents that inhibit LMW-PTP expression and/or activity operatively associated with the delivery vehicle. In another embodiment, the method of the invention comprises administering to a subject a composition comprising a nucleic acid comprising a nucleotide sequence encoding an EphA2 or EphA4 targeting moiety and an agent that inhibits or reduces LMW-PTP expression and/or activity. In yet another embodiment, the method of the invention comprises administering to a subject a composition comprising an EphA2 or EphA4 targeting moiety and a nucleic acid comprising a nucleotide sequence encoding an agent that inhibits or reduces LMW-PTP expression and/or activity, where the nucleic acid is operatively associated with the delivery vehicle. Pharmaceutical compositions are also provided by the present invention. |
