Claudin18.2 promote gastric cancer proliferation by activating MCM2/5.
Article in Scientific reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Pooled analysis of the SPOTLIGHT and GLOW phase III trials, involving 1072 patients with locally advanced or metastatic gastric/gastroesophageal junction (GC/GEJ) adenocarcinoma positive for claudin18.2 (CLDN18.2) and negative for HER2, showed that zolbetuximab combined with chemotherapy significantly improved progression-free survival (PFS) compared to placebo (HR = 0.72; 95% CI, 0.61-0.84). Subgroup analyses revealed better outcomes in Asian patients, those with gastric cancer, and those with intestinal-type GC. In a cohort of 92 GC patients (immunohistochemical detection based on a CLDN18.2 subtype-specific antibody), CLDN18.2 positivity was associated with lymph node metastasis, advanced cancer stages (III-IV), and shorter overall survival (OS) (HR = 1.728; 95% CI, 1.003-2.977; P = 0.0404). In our study, knockdown of CLDN18.2 inhibited tumor growth in vivo and in vitro. Additionally, CLDN18.2 knockdown down-regulated minichromosome maintenance (MCM) proteins, particularly MCM2 and MCM5, and decreased phosphorylation of ERK, CDK, and MCM2 in GC cells. These findings provide a theoretical basis for the future selection of advantageous populations for CLDN18.2-targeted therapy and combination therapy strategies.
