Molecular characterization and expression analysis of sodium pump genes in the marine red alga Porphyra yezoensis.
Article in Molecular biology reports, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 16 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
Sodium pumps (EC 3.6.3.9, Na(+)-ATPase), which mediate excretion of Na(+) from the cell, play a crucial role in Na(+) homeostasis in eukaryotic cells. The objective of this study is to understand the Na(+) efflux system in a marine red alga. We identified a novel sodium pump gene, PyKPA2, from the marine red alga Porphyra yezoensis. The amino acid sequence of PyKPA2 shares 65 % identity with PyKPA1, a previously identified P. yezoensis sodium pump. Similar to PyKPA1, PyKPA2 contains conserved sequences for functions such as phosphorylation, ATP binding, and cation binding. Phylogenetic analysis revealed that the two genes cluster with sodium pumps from algae. Reverse-transcription polymerase chain reaction (RT-PCR) analysis showed that PyKPA1 is expressed preferentially in sporophytes, whereas PyKPA2 is expressed specifically in gametophytes. RT-PCR and quantitative real-time PCR analysis revealed that PyKPA1 and PyKPA2 transcripts were upregulated and downregulated, respectively, in gametophytes during exposure to alkali stress. In addition, transcription of both genes in gametophytes was also induced by cold stress. These results suggest that PyKPA1 and PyKPA2 play an important role in alkali and cold stress tolerance.
