Regulation of autophagy by Rab27B in colorectal cancer.
Article in The international journal of biochemistry & cell biology, 2024. 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
Autophagy is a cellular recycling process that is associated with tumor growth, anti-tumor immune responses, and therapy resistance in colorectal cancer (CRC). In this report, we identify the small GTPase Rab27B to control the autophagy process in CRC. Depletion of Rab27B showed an abnormal accumulation of autophagy vesicles and increased autophagy markers in CRC cells, indicating autophagy dysregulation. Image analysis indicated that autophagy flux is blocked at the autophagosome/lysosome fusion step when Rab27B is lost. While Rab27B deficient cells are proficient at growth under 2D in vitro conditions, cell growth was significantly impacted in both in vitro 3D growth and in vivo tumorigenesis studies. Together, these results demonstrate a new role of Rab27B in the autophagy trafficking process in CRC and identify Rab27B as a potential therapeutic target for CRC.
