Akt signaling accelerates tumor recurrence following ras inhibition in the context of ink4a/arf loss.
Article in Genes & cancer, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Aberrant activation of the RAS signaling pathway contributes to nearly all human cancers, including gliomas. To determine the dependence of high-grade gliomas on this signaling pathway, we developed a doxycycline-regulated KRas glioma mouse model. Using this model we previously demonstrated that inhibition of KRas expression in gliomas induced by activated KRas and Akt results in complete tumor regression. We have also shown that, in the context of Ink4a/Arf loss, abrogation of KRas signaling is sufficient to decrease tumor burden but resistance ensues. In this study, we sought to determine the effect of activated Akt signaling in combination with activated KRas and loss of Ink4a/Arf on the growth and recurrence of brain tumors following suppression of KRas expression. We observed significant tumor formation in Ink4a/Arf(lox/lox) mice injected with retroviruses containing tetracycline responsive element (TRE)-KRas, Tet-off, Akt, and Cre. Abrogation of KRas signaling resulted in significant tumor regression; however, resistance developed after a relatively short latency. Tumor recurrence occurred more rapidly and the tumors were more aggressive in the presence of activated Akt signaling compared with loss of Ink4a/Arf alone suggesting that this pathway contributes to tumor progression in this context.
