Heat-induced transcription of diphtheria toxin A or its variants, CRM176 and CRM197: implications for pancreatic cancer gene therapy.
Article in Cancer gene therapy, 2010. 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
Vectors combining the heat shock proteins (HSPs) promoter with the catalytic subunit A of the diphtheria toxin (DTA) or its variants, cross-reacting material (CRM) 176 and 197, were engineered to investigate the effect of bacterial toxins on pancreatic cancer (PC) cells. Three heat-inducible enhanced green fluorescent protein (eGFP)-expression vectors were obtained: V1 (91% homology to HSPA6), V2 (five heat shock elements upstream the minimal HSPA6 promoter) and V3 (V1 and V2 combined). The highest eGFP transcription and translation levels were found in V3 transfected PC cells. The V3 promoter was used to control DTA, CRM176 and CRM197 expression, treatment response being investigated in four PC cell lines. DTAwt or CRM176 transfected cell growth was completely arrested after heat shock. CRM197 toxin presumed to be inactive, caused mild distress at 37 degrees C and induced a 25-50% reduction in cell growth after heat shock. Preliminary in vivo findings showed that heat treatment arrests tumor growth in DTA197 stably transfected PSN1 cells. In conclusion, the efficient HSP promoter identified in this study may be extremely useful in controlling the transcription of toxins such as CRM197, which have lethal dose-related effects, and may thus be a promising tool in PC gene therapy in vivo.
