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

To develop a new approach to the treatment of advanced, hormone-refractory prostate cancer, the signal transductions regulating the growth of human androgen-independent prostate carcinoma cell lines were studied. Agonist-stimulated Ca2+ mobilization, a critical regulatory event in other secretory cell types, was studied as a means of identifying previously undescribed plasma membrane receptors that may transduce a growth inhibitory signal. In all of the cell lines tested, P2-purinergic receptor agonists, including ATP and certain hydrolysis-resistant adenine nucleotides, induced a rapid, transient increase in cytoplasmic free Ca2+ that was detectable at 50 to 100 nM ATP, was maximal at 100 microM ATP, and was inhibited approximately 50% by chelation of extracellular Ca2+. Within 8 s after addition, ATP stimulated accumulation of the polyphosphatidylinositol products inositol (1, 4, 5) trisphosphate, inositol (1, 3, 4) trisphosphate, and inositol tetrakisphosphate. In addition to stimulating phosphatidylinositol turnover and Ca2+ mobilization, ATP and hydrolysis-resistant ATP analogues induced greater than 90% inhibition of the growth of all lines tested. These data demonstrate that human androgen-independent prostate carcinoma cells express functional P2-purinergic receptors linked to phospholipase C, and that agonists of this receptor are markedly growth inhibitory, suggesting a novel therapeutic approach to this common adult neoplasm.
