Latency-Associated Nuclear Antigen (LANA) Promotes Ferroptosis by Suppressing Nrf2/GPX4 and Upregulating MDM2.

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
Ferroptosis, an iron-dependent cell death driven by lipid peroxidation, is regulated by key mediators including glutathione peroxidase 4 (GPX4) and nuclear factor erythroid 2-related factor 2 (Nrf2). Kaposi's sarcoma-associated herpesvirus (KSHV) encodes latency-associated nuclear antigen (LANA), a multifunctional protein critical for viral persistence. Although studies reported that KSHV infection enhanced cellular resistance to ferroptosis, the specific role of LANA in this process remains unexplored. Here, we demonstrate that LANA unexpectedly promotes ferroptosis. In KSHV-positive iSLK.219 cells, LANA knockdown significantly attenuated RSL-3-induced ferroptosis, whereas LANA overexpression sensitized HeLa cells to ferroptotic death. Quantitative analysis revealed that LANA-depleted cells exhibited significantly elevated ROS accumulation (
