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

Latent membrane protein 2A (LMP2A) blocks B-cell receptor signal transduction in vitro by binding the Syk and Lyn protein tyrosine kinases. As well as blocking B-cell signal transduction, LMP2A has been shown to activate the phosphatidylinositol 3-kinase (PI3-K)/Akt pathway, which acts as a survival signal in both B cells and epithelial cells. Transforming growth factor beta 1 (TGF-beta 1) is a multifunctional cytokine that plays important roles in regulating cell growth and differentiation in many biological systems. The loss of the growth-inhibitory response to the TGF-beta 1 signal is found in many cancers and is widely thought to promote tumor development. In this study, we found that LMP2A induced the phosphorylation of Akt (serine 473) in Burkitt's lymphoma cell line Ramos and in gastric carcinoma cell line HSC-39 and partially enhanced cell viability following TGF-beta 1 treatment. In addition, LMP2A partially inhibited TGF-beta 1-induced DNA fragmentation and cleavage of poly(ADP-ribose) polymerase (PARP). In the presence of LY294002, an inhibitor of PI3-K, the LMP2A-mediated inhibitory effects on TGF-beta 1-induced DNA fragmentation and cleavage of PARP were alleviated. Furthermore, LMP2A did not alter the levels of expression of type I and type II TGF-beta 1 receptors. Taken together, these results suggest that LMP2A may inhibit TGF-beta 1-mediated apoptosis through activation of the PI3-K/Akt pathway.
