Biomarking and Induction of Apoptosis in Ovarian Cancer Using Bifunctional Polyethyleneimine-Caged Platinum Nanoclusters.
Article in Frontiers in oncology, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 1 paper.
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
According to the 2020 GLOBOCAN Global Cancer Women's Cancer Data, ovarian cancer is the eighth most common tumor in humans. Still, its mortality rate ranks first among all gynecological tumors, with a 5-year survival rate of 30% to 50%. Widespread clinical use of platinum-based drugs has improved survival outcomes in patients with ovarian cancer, but organ toxicity and drug resistance hinder their anticancer effects. In particular, the resistance to platinum drugs is an important reason for ovarian cancer's high recurrence rate and mortality. With the development of chemotherapeutic drugs synthesized by nanomaterials in the biomedical field, we developed bifunctional ultrafine polyethyleneimine caged platinum nanoclusters (PEI-Pt NCs) to improve the dilemma of platinum drugs. This study aimed to elucidate the antitumor effect of PEI-Pt NCs in OC. First, as observed by confocal microscopy, Pt NCs entered OC cells in a dose-dependent manner and accumulated on the surface of the nuclear membrane and in the nucleus. Subsequently, through cck8, ki-67 immunofluorescence, wound healing assay, transwell assay, clone formation assay, flow cytometry, tunel staining, and western blotting assay, it was confirmed that PEI-Pt NCs could inhibit the proliferation and migration and induce the apoptosis of ovarian cancer cells. PEI-Pt NCs can be used as fluorescent markers for systemic bioimaging of ovarian cancer, showing great potential in diagnosing and treating ovarian cancer, and making a specific contribution to solving the dilemma of platinum-based drug therapy for OC.
