1 · What the graph read from 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.

2 · The registry

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

The hypoxic microenvironment is an important contributor of glioblastoma (GBM) aggressiveness via HIF1α, while tumour inflammation is profoundly influenced by FAT Atypical Cadherin (FAT1). This study was designed to explore the functional interaction and significance of FAT1 and HIF1α under severe hypoxia-mimicking tumour microenvironment in primary human tumours. We first identified a positive correlation of FAT1 with HIF1α and its target genes in GBM tumour specimens, revealing the significance of the FAT1-HIF1α axis in glioma cells. We found that severe hypoxia leads to an increased expression of FAT1 and HIF1α in U87MG and U373MG cells. To reveal the relevance of FAT1 under hypoxic conditions, we depleted endogenous FAT1 under hypoxia and found a substantial reduction in the expression of HIF1α and its downstream target genes like CA9, GLUT1, VEGFA, MCT4, HK2, BNIP3 and REDD1, as well as a significant reduction in the invasiveness in GBM cells. At the molecular level, under hypoxia the FAT1 depletion-associated reduction in HIF1α was due to compromised EGFR-Akt signaling as well as increased VHL-dependent proteasomal degradation of HIF1α. In brief, for the first time, these results reveal an upstream master regulatory role of FAT1 in the expression and role of HIF1α under hypoxic conditions and that FAT1-HIF1α axis controls the invasiveness of GBM. Hence, FAT1 represents a novel potential therapeutic target for GBM.
