[Colorectal fibroblasts promote malignant phenotype of colorectal cancer cells by activating the ERK signaling pathway].
Article in Nan fang yi ke da xue xue bao = Journal of Southern Medical University, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectiveTo investigate the effect of human colorectal fibroblast (CCD-18Co)-conditioned medium (CCD18-Co-CM) on biological behaviors of colorectal cancer (CRC) cells and explore the possible molecular mechanisms.
methodsReal-time cellular analysis (RTCA), clone formation assay and wound healing assay were used to analyze the changes in proliferation, clone formation, and migration abilities of CRC cell lines HCT116 and Caco-2 treated with CCD18-Co-CM. Western blotting was used to detect the changes in ATK, ERK and STAT3 signaling pathways in the CRC cells activated by CCD18-Co-CM. The effect of CCD18-Co-CM on spheroidization ability of the cells was assessed with sphere-formation assay, and the changes in expressions of CRC stemness markers were detected using RT-PCR.
resultsCCD-18Co-CM significantly promoted proliferation, colony formation, and migration of HCT116 and Caco-2 cells, enhanced sphere-forming ability and expressions of CRC stemness markers, and increased ERK phosphorylation in the cells. Treatment with SCH772984 effectively inhibited CCD-18Co-CM-induced ERK signaling pathway activation, suppressed the malignant phenotype, and lowered the sphere-forming ability and expression of stemness markers of the two CRC cells.
conclusionColorectal fibroblasts promote malignant phenotype of CRC cells by activating the ERK signaling pathway.
