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

p150(Sal2), a vertebrate homologue of the Drosophila melanogaster homeotic transcription factor Spalt, has previously been shown to be a binding target of the polyomavirus large T antigen. p150(Sal2) acts as an inhibitor of viral DNA synthesis, and the binding of p150(Sal2) by large T overcomes this inhibition. The present study focuses on the effects of p150(Sal2) on the growth and survival of ovarian carcinoma (OVCA) cells that are deficient in expression of p150(Sal2) and of normal established human ovarian surface epithelial (HOSE) cells which abundantly express the protein. Transient expression of exogenous p150(Sal2) in OVCA cells that show little or no endogenous expression resulted in inhibition of DNA synthesis and colony formation and in increased apoptosis. OVCA cells stably transfected and expressing physiological levels of p150(Sal2) showed reduced tumorigenicity accompanied by increased expression of p21(WAF1/CIP1) (p21) and BAX. Conversely, reduction of endogenous levels of p150(Sal2) in HOSE resulted in reduced p21 expression and increased DNA synthesis. p150(Sal2) bound to the p21 promoter adjacent to the known p53 binding sites and stimulated transcription in the absence of p53. We propose that p150(Sal2), acting in part as a p53-independent regulator of p21 and BAX, can function in some cell types as a regulator of cell growth and survival.
