1 · What the graph read from it

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.

2 · The registry

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

Cutaneous squamous cell carcinoma (cSCC) is a common and aggressive skin cancer, with treatment options for advanced stages often limited by chemoresistance. Here, we observe a positive correlation between PHF20 expression and the malignancy and tumor grade of cSCC. Functional studies suggest that PHF20 promotes oncogenic phenotypes, including proliferation, invasion, and epithelial-mesenchymal transition. Notably, PHF20 depletion appears to sensitize cSCC cells to chemotherapeutic agents. Mechanistically, we show that PHF20 interacts with and promotes the ubiquitin-mediated degradation of GAS7. This downregulation of GAS7 is associated with nuclear F-actin assembly, a process that has been implicated in DNA damage repair (DDR). Consequently, PHF20 loss stabilizes GAS7, enhances nuclear F-actin assembly, and is accompanied by increased DNA damage accumulation. These in vitro findings were corroborated in vivo, where PHF20 knockdown suppressed tumor growth and increased DNA damage. Together, PHF20 may contribute to the regulation of DDR and chemotherapeutic response, highlighting its potential as a therapeutic target in poorly differentiated cSCC.
