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

Sugen kinase 495 (Sgk495), also known as Serine/Threonine Kinase 40 (STK40), is a pseudokinase previously implicated in T cell differentiation via regulation of Foxo transcription factors. However, its function and mechanism in lung squamous cell carcinoma (LUSC) remain unclear. Here, we report that Sgk495 is highly expressed in LUSC tissues and correlates with shorter disease-free survival in patients. Knockdown of Sgk495 significantly inhibited the proliferation, migration, and invasion of LUSC cells. Mechanistically, Sgk495 facilitates the binding of the E3 ubiquitin ligase COP1 to Foxo1, enhancing K48-linked polyubiquitination and subsequent proteasomal degradation of Foxo1. This process alleviates the tumor-suppressive effects of Foxo1, thereby promoting the oncogenic capabilities of LUSC cells in vivo. Our findings identify Sgk495 as an oncogene in LUSC acting through the COP1/Foxo1 axis, revealing a potential therapeutic target for this malignancy.
