Induction of miR-224 by Reactive Oxygen Species Regulates RASSF6 and Thus Modulates Malignant Behaviors and Chemosensitivity in Esophageal Squamous Cell Carcinoma.
Article in Journal of biochemical and molecular toxicology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Esophageal cancer is one of the most common malignant tumors of the digestive tract, and miR-224 can promote the hypoxia tolerance of esophageal cancer cells. The expression of miR-224 and HIF-1α in esophageal cancer cells under hypoxic induction and their relationship with ROS was studied using RT-qPCR and Western Blot assays; cell viability and apoptosis under hypoxia, as well as the effects of miR-224 on cell proliferation and drug resistance, were investigated using CCK8, Annexin V-FITC/PI, H2DCFDA staining and Western Blot assays. Under hypoxic induction, miR-224 and HIF-1α expressions were upregulated, with the upregulation of miR-224 being related to ROS accumulation, while HIF-1α upregulation was not affected by ROS. Furthermore, the upregulation of miR-224 facilitated the survival of esophageal cancer cells under hypoxic conditions and reduced their chemosensitivity to CDDP. This effect was also validated in vitro, as miR-224 overexpression promoted the malignant behaviors in ESCC cells. Under hypoxic induction, ROS accumulation can lead to the upregulation of miR-224. MiR-224 facilitates the survival of esophageal cancer cells under hypoxic conditions and induces chemotherapeutic drug resistance.
