Ubiquitin-Specific Protease 49 Interacts with Bax to Modulate Apoptosis.

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
Bax, a key member of the B-cell lymphoma 2 (Bcl-2) protein family, is essential for inducing mitochondrial apoptosis. In this study, we employed yeast two-hybrid screening to identify ubiquitin-specific protease 49 (USP49) as a binding partner of Bax. Subsequent immunoprecipitation and glutathione S-transferase (GST) pull-down assays confirmed their direct interaction. Functional assays showed that USP49 reduces Bax polyubiquitination at multiple lysine residues within ubiquitin, with the strongest effects observed on K11, K29, K33, and K63 linkages. In contrast, its effect on K48-linked ubiquitination was weak and insufficient to influence Bax protein stability, indicating that USP49 does not regulate Bax abundance through proteasomal degradation. Instead, RT-qPCR analysis revealed that USP49 overexpression significantly increased Bax mRNA levels, and this effect was maintained under apoptosis stimuli (UV, H
