Gene electrotransfer of plasmid AMEP, an integrin-targeted therapy, has antitumor and antiangiogenic action in murine B16 melanoma

Abstract: Gene therapy with Plasmid AMEP (antiangiogenic metargidin peptide) has recently been studied as a potential targeted therapy for melanoma. This plasmid is designed to downregulate α5β1 and αvβ3 integrins. In our study, electroporation was used as a nonviral delivery system. We investigated the antiangiogenic and direct antitumor effectiveness of this gene therapy on low and highly metastatic B16 melanoma variants. In vitro, the antiangiogenic effectiveness as determined by tube formation assay on endothelial c… Show more

“…In in vitro study with Plasmid AMEP, we showed good antimetastatic action, which was observed as reduced migratory and invasive potential of melanoma cells, with no effects on cell adhesion [3]. Furthermore, our in vivo gene therapy study on murine melanoma tumor also indicated on antimetastatic potential after intratumoral gene therapy with Plasmid AMEP [9]. Moreover, the first clinical Phase I/II study with intratumoraly administrated Plasmid AMEP conducted on 5 patients demonstrated good tolerability of Plasmid AMEP and local antitumor effectiveness in the treated lesions.…”

“…Множество проведенных исследований по изучению зако-номерностей роста и прогрессии опухолей кожи показа-ли, что чем выше содержание интегринов в опухоли, тем выше скорость ее инвазии и более выраженный ангиогенез [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20]. Суть этих исследований заключалась в сравнении количества интегринов на разных клонах одной и той же опухоли, с определением скорости роста, инвазии и мета-стазирования каждого из клонов с последующим сравне-нием их между собой.…”

“…Суть этих исследований заключалась в сравнении количества интегринов на разных клонах одной и той же опухоли, с определением скорости роста, инвазии и мета-стазирования каждого из клонов с последующим сравне-нием их между собой. Результаты всех исследований были схожими: клоны, имевшие самый быстрый и злокаче-ственный рост, показывали наибольшую экспрессию ин-тегринов по сравнению с менее агрессивными вариантами тех же опухолей [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20].…”

“…AMEP (Antiangiogenic MEtargidin Peptide) is the disintegrin domain of human metargidin (also known as ADAM-15). It is an anti-cancer agent with proven anti-angiogenic properties by binding of avb3 and a5b1 integrins on endothelial cells [15][16][17]. Furthermore, intramuscular gene electrotransfer of plasmid AMEP has been shown to inhibit tumor growth in murine models [17].…”
