Hsp70B' regulation and function.
Article in Cell stress & chaperones, 2007. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 50 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
Heat shock protein (Hsp) 70B' is a human Hsp70 chaperone that is strictly inducible, having little or no basal expression levels in most cells. Using siRNAs to knockdown Hsp70B' and Hsp72 in HT-29, SW-480, and CRL-1807 human colon cell lines, we have found that the two are regulated coordinately in response to stress. We also have found that proteasome inhibition is a potent activator of hsp70B'. Flow cytometry was used to assay hsp70B' promoter activity in HT-29eGFP cells in this study. Knockdown of both Hsp70B' and Hsp72 sensitized cells to heat stress and increasing concentrations of proteasome inhibitor. These data support the conclusion that Hsp72 is the primary Hsp70 family responder to increasing levels of proteotoxic stress, and Hsp70B' is a secondary responder. Interestingly ZnSO4 induces Hsp70B' and not Hsp72 in CRL-1807 cells, suggesting a stressor-specific primary role for Hsp70B'. Both Hsp70B' and Hsp72 are important for maintaining viability under conditions that increase the accumulation of damaged proteins in HT-29 cells. These findings are likely to be important in pathological conditions in which Hsp70B' contributes to cell survival.
