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

Valosin-containing protein (VCP) or p97, a member of AAA-ATPase protein family, has been associated with various cellular functions including endoplasmic reticulum-associated degradation (ERAD), Golgi membrane reassembly, autophagy, DNA repair, and cell division. Recent studies identified VCP and ubiquitin proteasome system (UPS) as synthetic lethal targets in ovarian cancer. Here, we describe the preclinical activity of VCP inhibitors in ovarian cancer. Results from our studies suggest that quinazoline-based VCP inhibitors initiate G1 cell cycle arrest, attenuate cap-dependent translation and induce programmed cell death via the intrinsic and the extrinsic modes of apoptosis. Mechanistic studies point to the unresolved unfolded protein response (UPR) as a mechanism by which VCP inhibitors contribute to cytotoxicity. These results support an emerging concept that UPR and endoplasmic reticulum (ER) stress pathways may be targeted in ovarian cancer as a source of vulnerability. Since prolonged ER stress may result in CHOP-mediated cell death, we tested the hypothesis that VCP inhibitors act synergistically with compounds that enhance CHOP expression. Here, we show that VCP inhibitors act synergistically with Salubrinal, an inhibitor of eIF2α dephosphorylation, by enhancing CHOP expression in ovarian cancer cell lines. Our results provide a proof-of-concept that VCP inhibitors can be used as a single agent and can be synergized with compounds that enhance CHOP expression to induce cell death in ovarian cancer cells.
