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
backgroundColorectal cancer (CRC) is a common and aggressive malignancy that frequently metastasizes to the liver, presenting significant therapeutic challenges. Despite its clinical importance, the mechanisms underlying CRC liver metastasis and resistance to immune therapy remain poorly understood. In this study, we aimed to investigate the molecular mechanisms driving CRC metastasis using a novel approach, which includes the establishment of highly metastatic CRC cell lines.
methodsTo explore the role of specific genes in CRC liver metastasis, we developed two highly metastatic CRC cell lines (LoVo-Hm and HCT116-Hm) by applying sustained selective pressure to primary CRC cells. RNA sequencing was performed to identify differentially expressed genes in these metastatic cells. Additionally, we conducted assays for cell migration, invasion, angiogenesis, and ELISA to evaluate VEGFA production, all to confirm the functional role of SLC9A2. Our findings were further validated in human CRC tissue samples and publicly available datasets to assess the clinical relevance of the identified targets.
resultsOur analysis revealed a significant downregulation of SLC9A2 in the highly metastatic CRC cell lines. Mechanistically, we found that SLC9A2 inhibits epithelial-mesenchymal transition (EMT) and metastasis by suppressing the STAT3 signaling pathway. Moreover, SLC9A2 reduces VEGFA secretion, normalizing tumor vasculature and reshaping the tumor microenvironment (TME), which ultimately enhances anti-tumor immunity. Comparative analysis of CRC tissue samples showed reduced SLC9A2 expression in tumor tissues compared to adjacent normal tissues, with a negative correlation to TNM staging. Importantly, higher SLC9A2 expression was associated with better treatment responses in immunotherapy cohorts.
conclusionThese findings highlight the critical role of SLC9A2 in regulating metastasis, angiogenesis, and TME remodeling in CRC. By modulating the STAT3 pathway and tumor vasculature, SLC9A2 emerges as a potential prognostic biomarker and therapeutic target. Targeting SLC9A2 may enhance immune responses and improve treatment outcomes in CRC, offering a promising avenue for future therapeutic strategies.
