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

Molecular mechanisms of prostate cancer progression are poorly understood. Here, we studied gene amplification of the large conductance calcium-activated potassium channel alpha subunit (KCNMA1), which is located at the chromosomal region 10q22. Fluorescence in situ hybridization (FISH) revealed KCNMA1 amplification in 16% of 119 late-stage human prostate cancers and in the hormone-insensitive prostate cancer cell line PC-3. In contrast, KCNMA1 amplification was absent in 33 benign controls, 32 precursor lesions and in 105 clinically organ-confined prostate cancers. Amplification was associated with mRNA and protein overexpression as well as increased density of BK channel protein and beta-estradiol-insensitive BK currents in PC-3 cells as compared to non-amplified control cell lines. Specific blockade of BK channels by iberiotoxin or RNA(i) significantly inhibited K(+) currents and growth of PC-3 cells. The data demonstrate that 10q22 amplification drives KCNMA1 expression and cell proliferation. Thus, KCNMA1 qualifies as a promising diagnostic and therapeutic target in patients with prostate cancer.
