Novel non-tumorigenic cell variants showing potentially different susceptibility to v-src-induced metastasis.
Article in Japanese journal of cancer research : Gann, 1990. 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
Two non-tumorigenic variant cells were isolated from UV-irradiated Balb/c 3T3 cells on the basis of their different responsiveness in phorbol ester-induced morphological change (rounding formation). They showed marked differences of lung metastatic potentials after intravenous injections of their v-src transformants into nude mice; phorbol ester-resistant variant TR4 cells transformed by v-src were hypermetastatic, whereas v-src transformants of phorbol ester-sensitive variant TR5 cells were not metastatic at all. These different metastatic responses were not observed in v-K-ras-induced transformants of the variants. These non-tumorigenic variant cells may pre-acquire the genetic alteration of certain src-specific and metastasis-associated factors. This system may be useful for genetic analysis of the induction of metastasis.
