Antitumor activity of cell-permeable p18(INK4c) with enhanced membrane and tissue penetration.
Article in Molecular therapy : the journal of the American Society of Gene Therapy, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Practical methods to deliver proteins systemically in animals have been hampered by poor tissue penetration and inefficient cytoplasmic localization of internalized proteins. We therefore pursued the development of improved macromolecule transduction domains (MTDs) and tested their ability to deliver therapeutically active p18(INK4c). MTD103 was identified from a screen of 1,500 signal peptides; tested for the ability to promote protein uptake by cells and tissues; and analyzed with regard to the mechanism of protein uptake and the delivery of biologically active p18(INK4c) into cancer cells. The therapeutic potential of cell-permeable MTD103p18(INK4c) (CP-p18(INK4c)) was tested in the HCT116 tumor xenograft model. MTD103p18(INK4c) appeared to traverse plasma membranes directly, was transferred from cell-to-cell and was therapeutically effective against cancer xenografts, inhibiting tumor growth by 86-98% after 5 weeks (P < 0.05). The therapeutic responses to CP-p18(INK4c) were accompanied by high levels of apoptosis in tumor cells. In addition to enhancing systemic delivery of CP-p18(INK4c) to normal tissues and cancer xenografts, the MTD103 sequence delayed protein clearance from the blood, liver and spleen. These results demonstrate that macromolecule intracellular transduction technology (MITT), enabled by MTDs, may provide novel protein therapies against cancer and other diseases.
