Primary cilium-dependent autophagy drafts PIK3C2A to generate PtdIns3P in response to shear stress.
Article in Autophagy, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
Primary cilium-dependent macroautophagy/autophagy is induced by the urinary flow in epithelial cells of the kidney proximal tubule. A major physiological outcome of this cascade is the control of cell size. Some components of the ATG machinery are recruited at the primary cilium to generate autophagic structures. Shear stress induced by the liquid flow promotes PtdIns3P synthesis at the primary cilium, and this lipid is required both for ciliogenesis and initiation of autophagy. We showed that PtdIns3P is generated by PIK3C2A, but not by PIK3C3/VPS34, during flow-associated primary cilium-dependent autophagy, in a ULK1-independent manner. Along the same line BECN1 (beclin 1), a partner of PIK3C3 in starvation-induced autophagy, is not recruited at the primary cilium under shear stress. Thus, kidney epithelial cells mobilize different PtdIns 3-kinases, ABBREVIATIONS: PtdIns3P: phosphatidylinositol-3-phosphate; PIK3C2A: class two alpha phosphatidylinositol 3-kinase; PIK3C3/VPS34: class three phosphatidylinositol 3-kinase; ATG: autophagy associated genes.
