Platycodin D represses β-catenin to suppress metastasis of cetuximab-treated KRAS wild-type colorectal cancer cells.

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
Cetuximab, an epidermal growth factor receptor (EGFR) inhibitor, is extensively used for clinical therapy in KRAS wild-type colorectal cancer (CRC) patients. However, some patients still cannot get benefit from the therapy, because metastasis and resistance occur frequently after cetuximab treatment. New adjunctive therapy is urgently needed to suppress metastasis of cetuximab-treated CRC cells. In this study, we used two KRAS wild-type CRC cells, HT29 and CaCo2, to investigate whether platycodin D, a triterpenoid saponin isolated from Chinese medicinal herb Platycodon grandifloras, is able to suppress the metastasis of cetuximab-treated CRC. Label-free quantitative proteomics analyses showed that platycodin D but not cetuximab significantly inhibited expression of β-catenin in both CRC cells, and suggested that platycodin D counteracted the inhibition effect of cetuximab on cell adherence and functioned in repressing cell migration and invasion. Western blot results showed that single platycodin D treatment or combined platycodin D and cetuximab enhanced inhibition effects on expressions of key genes in Wnt/β-catenin signaling pathway, including β-catenin, c-Myc, Cyclin D1 and MMP-7, compared to single cetuximab treatment. Scratch wound-healing and transwell assays showed that platycodin D combined with cetuximab suppressed migration and invasion of CRC cells, respectively. Pulmonary metastasis model of HT29 and CaCo2 in nu/nu nude mice consistently showed that combined treatment using platycodin D and cetuximab inhibited metastasis significantly in vivo. Our findings provide a potential strategy to inhibit CRC metastasis during cetuximab therapy by addition of platycodin D.
