Bone Marrow-Derived Myofibroblasts Promote Gastric Cancer Metastasis by Activating TGF-β1 and IL-6/STAT3 Signalling Loop.
Article in OncoTargets and therapy, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
backgroundMurine bone marrow-derived myofibroblasts (BMFs) have previously been shown to promote gastric cancer growth. However, whether BMFs promote gastric cancer cell metastasis remains largely unknown.
methodsWound healing assay, Transwell invasion and migration assay and 3D organotypic co-culture systems were conducted to study the effects of BMFs on invasion and migration of gastric cancer cells and the invasion and migration ability of gastric cancer stem cell-like cells (CSC-LCs) induced by BMFs. We employed two animal model to study the role of BMFs on the in vivo metastasis of gastric cancer cells and the metastatic ability of gastric BMF-induced CSC-LCs. A human gastric cancer tissue microarray and TCGA gastric cancer database were analysed to study the relationship between the expression of IL-6 and TGF-β1 and clinicopathological characteristics and survival in gastric cancer.
resultsWe found that BMFs promoted the in vitro migration and invasion of gastric cancer cells. BMFs promoted liver, lung, subcutaneous, and splenic metastases of MKN28 cells in the spleen injection liver metastasis model and co-injection of caudal vein (IOCV) mouse model. BMFs reprogrammed non-gastric cancer stem cell (CSC) to CSC-LCs and enhanced CSC-LC migration and metastasis. BMF-derived IL-6 and gastric cancer cell-secreted TGF-β1 mediated the interaction between BMFs and gastric cancer cells, promoting tumour metastasis. BMFs enhanced the expressions of STAT3 and p-STAT3 in co-cultured gastric cancer cells. A combination of Napabucasin and Galunisertib exhibited the strongest inhibition of cell migration compared to when administered alone. Gastric cancer tissue array and TCGA database indicated that the overexpression of IL-6 and TGF-β1 was associated with gastric cancer metastasis.
conclusionOur results demonstrated that BMFs promote gastric cancer metastasis through the activation of the TGF-β1 and IL-6/STAT3 signalling pathways. Targeting the inhibition of these interactions may be a potent therapeutic strategy for addressing gastric cancer metastasis.
