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

As deregulation of RAS signaling is important in the pathogenesis of myeloid leukemias, molecular targeting of RAS signaling may be a promising therapeutic strategy. Farnesyl transferase inhibitors (FTIs) are the most promising class of these new cancer therapeutics. Several FTIs have entered phase II clinical trials in acute myeloid leukemia (AML). Since geranylgeranylation of K-RAS and N-RAS in the presence of FTIs may represent an important mechanism of FTI resistance, 6 geranylgeranyl transferase-I inhibitors (GGTIs) were screened alone and in combination with FTI for growth inhibition of myeloid leukemia cells. Significant growth inhibition (>70%) in myeloid cell lines was observed for GGTI-286 (9/19), GGTI-298 (14/19), GGTI-2147 (16/19) and FTI L-744,832 (17/17). GGTI treatment of NB-4 cells resulted in an accumulation of cells in G(0)/G(1), whereas FTI L-744,832 primarily caused an increase in G(2)/M. FTI and GGTIs both induced apoptosis. In all cases, FTI/GGTI cotreatment led to synergistic cytotoxic effects in both myeloid cell lines (5/5) and primary AML cells (6/6). This synergy coincided with increased apoptosis. FTI/GGTI cotreatment caused an accumulation of unprocessed N-RAS and inactive N-RAS-RAF complexes. Our results suggest that alternative geranylgeranylation of N-RAS may represent an important mechanism of resistance to FTI monotherapy in myeloid leukemia cells.
