Transcriptional analysis of the hsp70 gene in a haloarchaeon Natrinema sp. J7 under heat and cold stress.

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
Although ubiquitous in all haloarchaea, little is known about the transcription and regulation of the haloarchaeal hsp70. The purpose of this study is to investigate the transcription of the haloarchaeal hsp70 gene in Natrinema sp. J7 under the temperature and osmotic stress. The hsp70 gene was found to be both temperature- and osmotic-induced, while the response of hsp70 to cold shock was stronger than that to heat shock. Western blot analysis corroborated the similar results at the level of Hsp70 protein. Northern blot and primer extension analyses indicated that the hsp70 was transcribed into a monocistronic transcript and the thermal stress had no effect on the transcription initiation sites choice. The deletion analyses showed that two putative elements, TATA-box (TTTAAAA) and BRE (AGTAAC) located -27 bp upstream of the transcription initiation site played an essential role for the basal transcription of P( hsp70 ). The results suggested that there are some special regulators of hsp70 gene in Natrinema sp. J7.
