Enhanced growth inhibition of prostate cancer in vitro and in vivo by a recombinant adenovirus-mediated dual-aptamer modified drug delivery system.

abstract：:We investigated the influence of TNF-alpha on the metastasis of cancer cells. Treatment of cultured colon 26 cells with TNF-alpha enhanced metastatic properties including production of MMP-9, adhesion, migration and invasion. Cells treated with TNF-alpha in vitro showed marked potential to metastasize to the lung and ...
