DNA microarray analysis of anaerobic Methanosarcina barkeri reveals responses to heat shock and air exposure.
Article in Journal of industrial microbiology & biotechnology, 2006. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 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
Methanosarcina barkeri is a methanogenic archaeon that can digest cellulose and other polysaccharides to produce methane. It can only grow under strictly anoxic conditions, but which can survive air exposure. To obtain further knowledge of cellular changes occurring in M. barkeri in response to air exposure and other environmental stresses, we constructed the first oligonucleotide microarray for M. barkeri and used it to investigate the global transcriptomic responses of M. barkeri to air exposure and heat shock at 45 degrees C for 1 h. The results showed that various house-keeping genes, such as genes involved in DNA replication recombination and repair, energy production and conversion, and protein turnover were regulated by environmental stimuli. In response to air exposure, up-regulation of a large number of transposase encoding genes was observed. However, no differential expression of genes encoding superoxide dismutase, catalase, nonspecific peroxidases or thioredoxin reductase was observed in response to air exposure, implying that no significant level of reactive oxygen species has been formed under air exposure. In response to heat shock, both Hsp70 (DnaK-DnaJ-GrpE chaperone system) the Hsp60 (GroEL) systems were up-regulated, suggesting that they may play an important role in protein biogenesis in M. barkeri during heat stress.
