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

The human glioma cell lines, U87 and T98G, were evaluated for their ability to survive and form colonies in an acidic environment of pH(ext) 6.0. In contrast to U87, which showed an 80-90% survival rate, only 40% of T98G cells survived 6 days at pH(ext) 6.0 and lost their colony forming ability when returned to a normocidic environment. Although both U87 and T98G cells maintain an intracellular pH (pH(i)) of 7.0 at pH(ext) 6.0 and arrest mostly in G1 phase of the cell cycle, only T98G demonstrated a major loss of cyclin D1 that was prevented by the proteasome inhibitor MG132. Colony forming ability was restored by stably transfecting T98G cells with a cyclin D1-expressing plasmid. Both U87 and T98G cells demonstrated increased cytoplasmic localization of cyclin D1 during exposure at pH(ext) 6.0. Upon prolonged (24 h) incubation at pH(ext) 6.0, nuclear cyclin D1 was nearly absent in T98G in contrast to U87 cells. Thus, an acidic environment triggers cytoplasmic localization and proteasomal degradation of cyclin D1.
