PAR2 promotes malignancy in lung adenocarcinoma.
Article in American journal of translational research, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Proteinase-activated receptor-2 (PAR2) is closely linked to tumor malignancy, but its biological role in cancer remains underexplored. In this study, we assessed PAR2 expression in lung adenocarcinoma (LUAD) and normal lung tissues, analyzed associations between clinicopathological features and survival rates, and confirmed that PAR2 promotes apoptosis resistance and reduces cisplatin-induced cytotoxicity in lung cancer cells. Using TCGA datasets, western blotting, qPCR, and immunohistochemistry (IHC), we observed a significant increase in PAR2 levels in LUAD samples compared to normal tissues (P<0.05), with high PAR2 expression correlating with poor differentiation and lymphatic invasion (P<0.05). Upregulated PAR2 was associated with reduced survival. Additionally, PAR2 inhibition increased the BAX/BCL-2 axis and contributed to cisplatin-induced endoplasmic reticulum stress and apoptosis in H1299 cells. However, PAR2 inhibition reduced cisplatin-induced ATF4 expression. Overall, PAR2 upregulation is strongly associated with poor postoperative survival, differentiation, and lymphatic metastasis in LUAD and modulates cisplatin cytotoxicity.
