Copper-induced intracellular calcium release requires extracellular calcium entry and activation of L-type voltage-dependent calcium channels in Ulva compressa.

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 marine alga Ulva compressa exposed to 10 µM copper showed a triphasic increase of intracellular calcium with maximal levels at 2, 3 and 12 h involving the activation of ryanodine-, Ins(1,4,5)P3- and NAADP-sensitive calcium channels. In order to analyze the requirement of extracellular calcium entry for intracellular calcium release as well as the activation of voltage-dependent calcium channels (VDCC) and phospholipase C, U. compressa was treated with EGTA, a non-permeable calcium chelating agent, with verapamil, nipfedipine and diltiazem, inhibitors of L-type VDCC, and with neomycin and U731222, inhibitors of phospholipase C. The release of intracellular calcium was partially inhibited with EGTA at 2 and 3 h and completely inhibited at 12 h of copper exposure and decreased with inhibitors of L-type VDCC and phospholipase C. Thus, copper-induced intracellular calcium release depends on calcium entry and activation of L-type VDCC and phospholipase C. An integrative model of copper-induced cellular responses in U. compressa is presented.
