The role of protein kinase C and cyclic AMP in the ammonia-induced shift of the taurine uptake/efflux balance towards efflux in C6 cells.

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
A previous study showed that treatment of C6 glioma cells with 10 mM ammonium chloride monia") for 24 h decreases taurine uptake and evokes sodium-dependent taurine efflux, indicating reversal of the taurine transporter (TauT)-mediated transport as an underlying mechanism. Consistent with the involvement of TauT we now show that the ammonia-induced changes in Tau uptake and efflux are inhibited by the protein kinase C (PKC) activator phorbol 12,13-dibutyrate (PDBu). Ammonia treatment of C6 cells resulted in increased intracellular accumulation of cAMP. Incubation of the cells with dibutyryl cAMP (dbcAMP) mimicked the effects of ammonia on both taurine uptake and efflux. The effects of dbcAMP on taurine uptake and efflux were additive to the effects of ammonia. Collectively, the results suggest that the effects of ammonia on taurine uptake and efflux may be partly mediated by cAMP. Consistent with this mechanism, the adenyl cyclase inhibitor, miconazole reduced the stimulation of efflux by ammonia.
