RBMS1 interference inhibits malignant progression of glioblastoma cells and promotes ferroptosis.

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
backgroundGlioblastoma (GBM) is a brain tumor characterized by the highest malignancy and the poorest prognoses. RNA binding motif single strand interacting protein 1 (RBMS1) has been implicated to be involved in various cancer progression. This study was conceived to explore the role and the mechanism of RBMS1 in GBM. MATERIALS: RT-qPCR and western blot were used to evaluate RBMS1 expression and examine the transfection efficiency of sh-RBMS1. Cell proliferation was detected using CCK-8 assay and colony formation assay while cell apoptosis was detected with flow cytometry. Cell migration and invasion were detected with wound healing and transwell assay. The activities of MMP2 and MMP9 were detected using gelatin zymography. Western blot was used to measure proliferation-, apoptosis-, ferroptosis- and EMT-related proteins. Lipid peroxidation was detected with TBARS Assay Kit and lipid ROS was detected with a BODIPY 581/591 C11 kit. The total iron level was detected using corresponding assay kits.
resultsAccording to GEPIA database, RBMS1 expression was upregulated in GBM and the present study found that RBMS1 expression was upregulated in GBM cells. After interfering RBMS1, GBM cell proliferation, migration, invasion and EMT process were inhibited while cell apoptosis and ferroptosis were promoted. However, ferroptosis inhibitor Fer-1 partially counteracted the protective effects of RBMS1 knockdown on GBM.
conclusionCollectively, this study revealed that RBMS1 silence inhibited the malignant progression of GBM possibly through ferroptosis.
