    摘要: Embodiments of the invention are directed methods that include a thymidine kinase deficient vaccinia virus. The methods include administering the vaccinia virus at increased viral concentrations. Further aspects of the invention include methods for inducing oncolysis or collapse of tumor vasculature in a subject having a tumor comprising administering to a subject administered at least 1×108 viral particles of a TK-deficient, GM-CSF-expressing, replication-competent vaccinia virus vector sufficient to induce oncolysis of cells in the tumor.

    摘要: Cripto, a developmental oncoprotein, antagonizes activin and TGF-β signaling by forming a complex with activin and TGF-β and their type II receptors. This complex precludes the formation of a functional activin/TGF-β•type II•type I complex, thereby blocking the signaling of activin and TGF-β. Cripto may be generally capable of blocking antiproliferative Smad2/3 signals and provides a novel mechanism of oncogenic action with multiple therapeutic implications. Inhibiting the formation of Cripto and activin/TGF-β complex may enhance antiproliferative effects of activin and TGF-β.
