Inhibition of autophagy by 3-methyladenine promotes migration and invasion of colon cancer cells through epithelial mesenchymal transformation.
Article in Translational cancer research, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 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
Background: Colon cancer is the third leading cause of tumor-related deaths in the world. Inhibition of autophagy in the treatment of malignant tumors has attracted extensive attention. However, the association between inhibition of autophagy by 3-methyladenine (3-MA) and epithelial mesenchymal transformation (EMT) in colon cancer cells has not yet been fully elucidated. Methods: In this study, colon cancer cell lines (LOVO and SW620) were treated with 3-MA. Wound healing assays and transwell assays were used to detect the effect of inhibition of autophagy on the migration and invasion of colon cancer cells. The expression of EMT-associated markers, Twist1, E-cadherin, and vimentin, in colon cancer cells with and without 3-MA treatment was detected by Western blotting, immunohistochemistry, immunofluorescence staining, and real-time quantitative reverse transcription polymerase chain reaction (qRT-PCR). Results: Our data showed that inhibition of autophagy by 3-MA significantly enhanced the migration and invasion of colon cancer cells. At the molecular level, inhibition of autophagy upregulated the expression of Twist1 and vimentin, downregulated the expression of E-cadherin, and induced the EMT of colon cancer cells. Conclusions: Inhibition of autophagy by 3-MA upregulated the expression of Twist1 in colon cancer cells and promoted cancer cell migration and invasion through EMT. Inhibition of autophagy may have adverse effects on colon cancer.
