Cytotoxicity of liposomal alpha-tocopheryl succinate towards hamster cheek pouch carcinoma (HCPC-1) cells in culture.
Article in Cancer letters, 2006. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
There is compelling evidence for the cancer chemopreventive effects of vitamin E and related compounds. Of all the vitamin E derivatives that have been investigated to date, vitamin E acid succinate is the most effective anti-cancer agent. This report describes the preparation and testing of liposomal formulation of mono alpha-tocopheryl ester of succinic acid (alpha-TOS) for cytotoxicity against hamster cheek pouch carcinoma cell line (HCPC-1). Small unilamellar vesicles (SUV) of phosphatidylcholine incorporating 70 microM alpha-TOS were superior to alpha-TOS alone or SUV without incorporated alpha-TOS, as inducers of apoptosis in HCPC-1 cells. Liposomal alpha-TOS perturbed the lipid structure in cells, promoted apoptosis, and decreased cell viability. The mechanism of action of alpha-TOS appears to involve membrane damage and induction of ceramide mediated apoptosis.
