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

backgroundEpithelial ovarian cancer (EOC) is an alarming malignancy with frequent relapse and resistance to chemotherapy. Understanding the mechanism related to these phenotypes is urgent. Here, we investigated the roles of inflammasomes, NLRP1 and NLRP3, and pyroptosis in EOC progression and resistance to treatment.

methodsCell viability under cisplatin (CDDP) treatment was measured with diphenyltetrazolium bromide (MTT), and the IC50 values were calculated for the A2780, ACRP, and OVCAR3 cell lines. The levels of cytokines (interleukin-1β, IL-6, and TNFα) present in the supernatant were measured via ELISA. Caspase-1 activation was detected through the Caspase-Glo® 1 Assay. The cell death profile was determined via flow cytometry using Annexin V/PI staining, and the formation of pores in the cell membrane was measured using PI. A wound healing assay was used to investigate the effects of treatment with CDDP combined with a caspase-1 inhibitor (Ac-YVAD-CHO) on cell migration.

resultsIC50 values indicate increasing CDDP resistance across the following cell lines: A2780 (10.41 μM), ACRP (35.92 μM), and OVCAR3 (43.52 μM). Cytokine secretion and Caspase-1 activation were greater in treated cells than in untreated cells. CDDP-treated cells exhibited increased lytic cell death and pore formation. Caspase-1 inhibition during treatment with CDDP reduced wound closure, indicating reduced cell migration.

conclusionOur findings suggest that inflammasome activation and pyroptosis are mechanisms associated with ovarian cancer chemoresistance to CDDP, contributing to the devastating scenario of this disease. Targeting the NLRP1 and NLRP3 pathways could represent a promising strategy to improve OC treatment.
