Loss of AMBRA1 activates MAPK and angiogenesis signaling pathways in melanoma cells.
Article in FEBS open bio, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
The protein activating molecule in Beclin1-regulated autophagy1 (AMBRA1), discovered in 2007, is crucial for autophagy and plays roles in nervous system development, cell survival, and proliferation. Here, we investigated AMBRA1's involvement in various cellular processes using a systems-based "omics" approach, focusing on melanoma. Transcriptomic analysis of AMBRA1 overexpression or knock-down was shown to result in significant dysregulation of several transcripts. We identified several novel roles for AMBRA1 in a range of cellular pathways including cancer signaling pathways such as MAPK, angiogenesis, tissue growth factor signaling, axon guidance, and Wnt signaling. Furthermore, using yeast two-hybrid assays, we identified novel binding partners which provide evidence of new roles for AMBRA1 in different cellular processes. Ultimately, we conclude that AMBRA1 loss upregulates metastatic genes/proteins highlighting AMBRA1 as a tumor suppressor gene in melanoma.
