Yuanhuacine suppresses head and neck cancer growth by promoting ASCT2 degradation and inhibiting glutamine uptake.

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
Head and neck squamous cell carcinoma (HNSCC) cells exhibit a high dependency on glutamine metabolism, making it an attractive target. Despite the well-established link between glutamine reliance and tumor progression, the specific role of glutamine transporters in HNSCC remains poorly understood. The alanine-serine-cysteine transporter 2 (ASCT2), a key glutamine transporter, is overexpressed in HNSCC, and its silencing has been shown to reduce intracellular glutamine and glutathione levels, inhibiting tumor growth. These facts suggest that targeting ASCT2-mediated glutamine uptake could offer a promising therapeutic strategy for HNSCC. But no clinically approved drugs directly target ASCT2, and challenges such as the limited stability of antisense oligonucleotides persist. In this study we evaluated the correlation between ASCT2-mediate glutamine metabolism and its impact on HNSCC patients. We established a virtual screening method followed by cytotoxic assays to identify small molecules that specifically target ASCT2. Among the top 15 candidates, we identified yuanhuacine (YC) as the most potent antitumor compound with IC
