USP4 promotes proliferation and metastasis in human lung adenocarcinoma.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
Research the expression of USP4 in lung adenocarcinoma and its correlation with clinicopathological features and prognosis analysis, to explore the invasion and metastasis mechanism of USP4 in lung adenocarcinoma, and to clarify the mechanism of USP4's involvement in the occurrence and development of lung adenocarcinoma. The expressions of USP4, VEGF, MMP2 and Ki67 in lung adenocarcinoma and adjacent tissues of 139 patients with lung adenocarcinoma were detected by immunohistochemical method, and the correlation between expression and clinicopathological features and survival curve were analyzed by statistical method. The expression of USP4 was interfered by LIP-2000 cell transfection technology, and the expression of USP4 and its related factors in protein level was detected by Western Blot, and their correlation was analyzed. After silencing USP4 expression, the effects of USP4 on proliferation, invasion and migration of lung adenocarcinoma cells were detected by cell scratches assay, MTT assay, Transwell assay and tumorigenesis assay in nude mice. The expression of USP4 in lung adenocarcinoma tissues was higher than that in normal adjacent tissues, and the high expression of USP4 was significantly correlated with the differentiation degree of lung adenocarcinoma, clinical stage and pathological grade lymph node metastasis. After silencing USP4 expression, the expression of cyclin apoptosis protein invasion related proteins and phosphorylation factors were affected, and then cell migration and the proliferation ability decreased, the number of invasion and metastasis decreased, and the tumor volume decreased in nude mice. USP4 may play a certain role in the invasion and metastasis of lung adenocarcinoma by regulating the expression of tumor-related factors and affecting the prognosis of patients with lung adenocarcinoma. USP4 can be used as a potential therapeutic target for clinical diagnosis of lung adenocarcinoma and provide a new opportunity for clinical research on lung adenocarcinoma.
