Anterograde and retrograde transport of neutral sphingomyelinase-2 between the Golgi and the plasma membrane.

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 activation of neutral sphingomyelinase-2 (nSMase2) and consequent ceramide production are implicated in many stress-induced signaling pathways. Trafficking of nSMase2 from the Golgi compartment to the plasma membrane (PM) in response to signaling stimuli has been described. However, the precise mechanisms of transport remain unknown. This study aimed to investigate the trafficking of nSMase2 between the Golgi and the PM. We show here that V5-nSMase2 localizes at the PM and Golgi in MCF-7 cells and confirm relocalization of nSMase2 to the PM at confluence. Although cycloheximide (CHX) treatment partially inhibited the Golgi localization of GFP-nSMase2, recovery of GFP-nSMase2 to an intracellular compartment was still observed after photobleaching. Moreover, in the presence of CHX, GFP- and V5-nSMase2 co-localized with endosomal/recycling markers. In HEK293 cells, activation of either protein kinase C-alpha or betaII, with the phorbol ester PMA led to relocalization of both wild-type and inactive nSMase2 to the pericentrion, a PKC-dependent subset of recycling endosomes. Finally, inhibition of nSMase2 endocytosis by K+depletion reduced the intracellular pool of nSMase2 and increased nSMase2 activity resulting in elevated ceramide levels. Altogether, these results suggest that nSMase2 traffics from the Golgi to the PM as a membrane protein en route to the cell surface and recycles back to the Golgi through the endosomal/recycling compartment. Moreover, the recycling of nSMase2 from the PM is important for its catalytic regulation.
