Osteoblastic ferroptosis inhibition by small-molecule promoting GPX4 activation for peri-prosthetic osteolysis therapy.
Article in Journal of nanobiotechnology, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
Peri-prosthesis osteolysis (PPO) represents the most severe complication of total joint arthroplasty (TJA) surgery and imposes the primary cause of prosthesis failure and subsequent revision surgery. Antiresorptive therapies are usually prescribed to treat PPO, especially for elderly people. Nevertheless, the efficacy of anti-osteoporotic medications remains constrained. Recent therapeutic strategies to promote periprosthetic osseointegration by restoring osteoblast function are considered more effective approaches. However, the precise mechanism underlying the inhibition of osteogenesis triggered by wear particles remains enigmatic. Herein, we demonstrate that wear particles inhibit osteoblast function by inducing ferroptosis to sabotage extracellular mineralization and arouse periprosthetic osteolysis. The suppression of ferroptosis could significantly rescue osteogenesis thus alleviating PPO. Furthermore, Glutathione Peroxidase 4 (GPX4) has been identified as a key target in regulating osteoblastic ferroptosis. By utilizing virtual screening techniques, we have successfully conducted a comprehensive screening of a natural compound known as Urolithin A (UA), which exhibits remarkable inhibition of osteoblastic ferroptosis while simultaneously promoting the process of osteogenesis through its precise targeting mechanism on GPX4. Meanwhile, UA improves the osteolytic conditions significantly in vivo even when the adjunction of titanium (Ti) nanoparticles. This strategy has great potential in treating peri-prosthesis osteolysis and potentially broadens the scope of clinical therapy.
