The COX-2 Inhibitor Celecoxib Sensitizes Nasopharyngeal Carcinoma Cells to Ferroptosis.
Article in Current cancer drug targets, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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.
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
backgroundNasopharyngeal cancer [NPC] is prevalent in Southeast Asia and North Africa, and is generally associated with limited treatment options and poor patient prognosis.
objectiveFerroptosis is a recently observed cell death modality and has been shown to link to the efficacy of different anti-cancer treatments, thus offering opportunities for the development of novel therapies. This study aims to investigate the potentiating effects of COX-2 inhibitors on ferroptosis in nasopharyngeal cancer.
methodsThe inhibitory effects of COX-2 inhibitors celecoxib and rofecoxib on nasopharyngeal cancer cells were assessed with MTT, colony formation, sphere formation, Transwell, and wound healing assays. The status of COX-2 with celecoxib and rofecoxib treatment was investigated by Western blotting and immunofluorescence experiments. Ferroptosis was induced with the GPX4 inhibitor RSL3 with or without COX-2 inhibition and was monitored by fluorescence microscopy. Transcriptomic profiling was conducted with 5-8F cells treated with DMSO as control or celecoxib, and ferroptosis-related candidates were validated by RT-PCR analysis.
resultsCelecoxib and rofecoxib effectively inhibited the growth and migration of nasopharyngeal cancer cells. Both inhibitors evidently sensitized nasopharyngeal cancer cells to ferroptosis induction by RSL3, with celecoxib outperforming rofecoxib. Celecoxib treatment resulted in significantly differentially expressed genes in 5-8F cells, among which CHAC1 was validated as a ferroptosis-related target.
conclusionThe COX-2 inhibitor celecoxib effectively sensitized nasopharyngeal cancer cells to ferroptosis induction.
