ER-α36 mediates gastric cancer cell invasion.
Article in International journal of clinical and experimental pathology, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled it.
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
Estrogen evidently exerts a protective role against gastric cancer. Accordingly, we evaluated the relationship between the expression of the estrogen receptor ER-α36 and the clinicopathologic features in gastric cancer. ER-α36 expression levels differed among the tumor center, invasion front, and vascular metastases. The effects of E2β (17β-Estradiol, E2β) on invasion ability in SGC7901, High36 (with ER-α36 upregulation), and Low36 (with ER-α36 downregulation) cells were evaluated using Transwell assays. Furthermore, the c-Src signaling pathway was inhibited using PP2 and the effects on E2β-induced increases in E-cadherin, MMP2, and MMP9 were evaluated using western blotting. ER-α36, c-Src, MMP2, and E-cadherin levels were also evaluated in tumor xenografts. We found that 0.1 nM E2β promoted gastric cancer cell invasion by reducing E-cadherin expression and increasing MMP2 and MMP9 levels. The upregulation of ER-α36 promoted gastric cancer cell invasion and the downregulation of ER-α36 reduced the invasive ability of cells. The levels of ER-α36, c-Src, and MMP2 were the highest in tumor xenografts using High36 cells, intermediate in tumor xenografts using SGC7901 cells, and lowest in tumor xenografts using Low36 cells. The opposite results were obtained for E-cadherin expression. ER-α36 enhanced gastric cancer cell invasion by the activation of membrane-initiated c-Src signaling pathways. In particular, treatment with E2β and ER-α36 influenced gastric cancer cell invasion. Furthermore, c-Src was involved in the ER-α36-mediated estrogen signaling pathway and cell invasion.
