1 · What the graph read from it

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.

2 · The registry

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

Anchorage-independent growth (AIG) of cancer cells requires escape from integrin-mediated signals. A protein frequently downregulated in cancer, caveolin-1 (Cav1), mediates integrin control of several growth-regulatory pathways. We report that loss of Cav1 results in faster exit from quiescence and progress through the cell cycle, proliferation without anchorage to substrate, and absence of cyclin D1 downregulation upon serum deprivation or detachment. Surprisingly, this proliferative advantage is independent of Erk-mitogen-activated protein kinase signaling; instead, cyclin expression and cell cycle progression in the absence of Cav1 are driven by increased membrane order and Rac targeting. AIG was induced in Cav1-expressing cells by forced membrane targeting of Rac1 or by inhibiting Cav1-mediated internalization of plasma membrane ordered domains at which Rac1 accumulates. Restoring Rho activity, which is downregulated after loss of Cav1, antagonizes Rac1 and prevents cyclin D1 accumulation after serum starvation or loss of adhesion. Anchorage independence and increased proliferation in Cav1-deficient tumoral and null cells are thus due to an increased fraction of active Rac1 at membrane ordered domains. These results provide insight into the mechanisms regulating growth of cancer cells, which frequently lose Cav1 function.
